So why am I subjecting my sinuses to ancient tortures when I could be doing something fun like cleaning out the garage? Because there’s no better place to learn how to survive a helicopter water crash than here at the Marine Survival Training Center (MSTC) in Lafayette, Louisiana. I am enrolled in MSTC’s Helicopter Underwater Egress Training, or HUET course. After spending a full day in training, I’m convinced that my chances of surviving and exiting a submersed, inverted helicopter are significantly higher than they otherwise would Vol 3 Issue 1 Graphic courtesy of MSTC have been . That attitude stems from the reality of the training. MSTC is one of only two civilian survival training centers in the world fully equipped and staffed to teach helicopter pilots how to survive a ditching. MSTC caters to the Gulf area, but trains pilots from all over the world. A branch of the University of Louisiana at Lafayette, the training center has been teaching water survival skills since the 80’s. According to Jim Gunter, Acting Director of the center, MSTC now teaches between 4000 to 5000 souls annually in a broad range of vital marine survival skills. Originally established at the request and sponsorship of the offshore industry to teach lifeboat launch and survival skills to offshore crews, the now fully self-funding institution, boasts a comprehensive curriculum of over 18 classes. Those of particular interest to helicopter pilots include Basic Aviation Water Survival (BAWS) and Helicopter Underwater Egress Training (HUET). The class I’ve been invited to attend combines both BAWS and HUET and has been modified to include HEED III training. HEED III devices are small SCBA like systems with tank, regulator and mouthpiece all included in one, small, stick in a big pocket, package. A HEED III set up can provide one to three minutes of air—hopefully, enough to get you out of a complicated roll over accident. The hard part—remembering to breathe air through your mouth instead of water through your nose. Trust me! One of the things that makes MSTC unique in the field of water survival training is ‘The Dunker.’ Officially known as METS (Modular Egress Training Simulator), ‘The Dunker’ is a highly modified air frame that can be customized to represent nearly any helicopter in significant use over major bodies of water—everything from a B206 to an S76. Doors and windows can be swapped out to exactly match those found in the pilot’s or crew’s customary aircraft. The METS is attached to a large crane and a unique rollover system that can emulate the sometimes violent actions and motions of a real water landing and rollover. The METS allows you to experience and train in a very realistic simulation. But, before we get wet, there’s a morning of water survival training to attend to. “Be prepared”—not just for scouts Seven of us gathered early on this May morning to learn how to survive a water landing. Our small class included four Petroleum Helicopter (PHI) pilots, an offshore helicopter crew member, a U.S. Coast Guard officer, and myself. Surviving any crash, especially one into the drink, involves an element of luck. The purpose of the MSTC training is to minimize the luck factor by putting the ultimate outcome of a water landing more in the pilot’s control. There are at least five distinct phases to a ditching, each with its own keys to survival. They are preflight & preparation, the crash, underwater egress, water survival, and rescue. A failure in any one of the phases can drastically change the outcome of an otherwise survivable water landing. While the primary focus of the training is the crash and underwater egress, a reasonable amount of time is spent in the other three areas as well. Your best chance of avoiding the ditching altogether or preparing yourself and your passengers to survive it occurs in pre-flight and preparation. Being prepared encompasses aircraft pre-flight, clothing, survival equipment, passenger briefing and smart flying. Shoes look better dry Much of my flying is done in the deserts of the Southwest. So, with occasional exceptions, the only way I’m going to ditch is if I do an auto into a shimmering swimming pool in someone’s back yard. There have been some 110° F days when I’ve considered this to be an attractive option. Occasionally, however, even I find myself over a large body of water. Nearly all of us, at one point or another, will 3 • Signal mirror • Collapsible radar reflector • Rope • Anti-seasick pills • Plastic garbage bag (warmth, shelter, waste containment) • Roll yellow caution tape • Space blanket • Sea dye marker • Chem. lights on a lanyard (Swing in a circle for larger target) 42 Talk to your pax As pilots in command of an aircraft, we’re not only responsible for ourselves and our aircraft, we bear a huge responsibility to those who have entrusted their well being into our care—our passengers. The standard passenger briefing of, “put on your seat belt and don’t get out until I tell you,” does not stand up to the rigors of over water flight. Does your passenger know the basic crash brace position? For that matter, do you? Will they try to get out while the blades are still turning? Could they locate and open the door handle if they were severely disoriented? As PIC, you need to take the time to understand these points yourself and to explain them to your passengers. Your passenger briefing does not have to be a grueling, scare the crud out of everyone experience. Demonstrating a brace position, asking people to put their hands on their door side knees and locate the door handle from that position using their own body as a reference (i.e. towards my head or towards my feet) is neither too difficult nor too frightening. Remind them that in the event of a water landing, they are to remain in their seat belts until the aircraft has stabilized in whatever position it wishes to assume. The harness keeps them in constant reference to the doors and gives them leverage to push them open. Give them an opportunity to ask questions and answer them clearly. Nobody wants to think about the possibility of a crash landing. But, better to have a plan explained and understood than to wish you had in the few seconds between, “What the…” and “Hang on…” One more thing. If you’re going to be flying over a large body of water, or expect to fly over water with any frequency, invest in life vests for yourself and all your passengers. They can be had for around $60.00 U.S. and even on a bad day, my wife will tell you that I’m worth at least twice that. Do not ask my teenage daughter for her opinion. Make sure that everyone knows how and when to use them and put them on before you take off. Life vests should not be inflated until you have exited the aircraft. That is, not unless you want to find yourself firmly stuck against the floor of an upside down helicopter. Graphic courtesy of MSTC end up flying over or near big lakes, rivers and oceans. Fly higher over water than you might normally over land. By remaining a minimum of 1000 ft. AGL, you’ll have a little more time to brief your passengers and prepare for the landing—water or otherwise. Remain especially alert during takeoffs and landings. According to a MSTC analysis, more than 50% of water accidents occurred during these highrisk phases of flight. You are more likely to be flying inside shaded areas of the height-velocity chart and you will be closer to the ground with little or no time for last second preparations or reminders. Take a moment to reflect upon the relatively inhospitable nature of the surface below and do a good job on your planning and pre-flight. This is no time to do fuel management on a piece of scratch paper and you should be highly intolerant of marginal or questionable instrument readings or potential mechanical problems. A noise or vibration that may seem acceptable until the next 100 hour when flying over miles of open country, becomes much more ominous when Davy Jones awaits. Have your radio tuned to a frequency where you will be heard in the event of a sudden emergency. Have a good idea of your location at all times so you can provide a smaller search area to those who will come looking for you. And, of course, file either an internal or actual flight plan, and provide regular position Personal Ditching Kit updates so people Even if the helicopter does not will know where have an aircraft ditching kit, you’re going, consider making a personal kit where you are of your own. Here is a list of and when you items to consider: should be • Strobe light expected—or • Mk 13 day/night flares missed! • Knife & whistle Let’s get small Your chances of exiting an inverted helicopter and surviving in the water are greatly enhanced if you Vol 3 Issue 1 remain uninjured in the crash sequence. Believe it or not, there are things you can do to help. Crash injuries fall into two categories: acceleration and contact. Acceleration injuries occur when your body’s inertia is suddenly changed. You remember inertia—the tendency of a body in motion to continue in the same straight line unless acted upon by some external force. Your inertia becomes seriously hosed when a forward, descending, 60 knot autorotation suddenly stops as you slam into the crest of a wave. Good piloting technique plays a role here. Acceleration injuries can be reduced by reducing the energy of a ditching before it can be transmitted to the individuals on board. Another way this occurs The final thing we can do to protect ourselves from injury during a crash sequence is to assume a good brace position. Many helicopter crashes involve forward, downward, and rotational axis forces. Braces are designed to reduce the body’s movement and resulting secondary collisions. All braces are designed to protect the head and face and reduce flailing of the arms, legs and upper torso. is through the aircraft design itself. Energy absorbing equipment, like collapsible seats, dissipate energy before transmitting it to the pilot or passenger. Contact injuries occur when either you run into something or something runs into you. There are a number of things we can do to make a difference here. First, stow all loose items located in the cabin. I don’t know about you, but I’ve been in a few helicopters (piloted by someone else, of course) that had a broad range of projectiles just waiting to receive launch instructions: pens, flashlights, manuals, sunglasses, screwdrivers. I don’t care what it is, if it hits you in the face moving about 55-90 miles an hour, it is going to hurt! It is also in our best interest to minimize the size of our strike envelope. Make yourself a smaller target. This will help protect you against injury from foreign objects coming at you as well as injuries from you coming at foreign objects. The first line of defense against contact injury is a tight harness or seat belt. Your seat restraints should be as tight as possible, while still providing at least a minimal level of comfort. The loose ends of any straps should be tucked in. If left to dangle, they may become hung, prevent you from finding the release mechanisms or otherwise interfere with your ability to free yourself and exit the aircraft. for the controls to do. This means keeping your feet on the pedals, your left hand on the collective, your right hand on the cyclic and your eyes open. Even so, there are several steps you can take to help protect yourself. First, protect your thumbs. That’s right—thumbs. It’s much more difficult to undo a seat belt and exit an inverted helicopter with one or two broken thumbs. To give your hands a better chance of escaping without injury, prior to crash, bring your thumbs around to rest in a natural position in line with your other fingers. Your thumb should be resting on top of your pointer finger. By eliminating the opposable thumb position you’re reducing the chance of significant hand injury. Another action available to the pilot is also available to others. Consciously ‘suck’ your head down deeper between your shoulders—turtle fashion. This will not only reduce your strike envelope, but it will also lend additional support to your neck and spine. (Please do not get me going on where you should stick your head in the event of a crash…) Once the helicopter is in the water the pilot should assume the brace position of the pilot not in control. Graphics courtesy of MSTC Pilot in control If you are the pilot in control, you are a little bit out of luck here. You need to continue to fly the helicopter until contact is made with the water, the main rotors have stopped and there’s nothing more Pilot not in control Because violent inputs can be transmitted back 5 3 Pax If a passenger has a full harness on, then their brace position resembles that of the pilot not flying. If they only have a lap belt they should bend forward at the waist with their head down against the knees. 2 6 Knees should be held firmly together with the feet flat on the floor about 4 to 6 inches apart. The arm closest to the primary exit should be wrapped under the thighs with the hand gripping the opposite thigh or pants. The other hand needs to grip the edge of the seat close to the pant seam. Remember, the hand wrapped under the knees is used to locate the exit and the hand gripping the seat is used to release the seat belt. Complete disorientation After completing the morning’s classroom session, prior to entering ‘The Dunker,’ I remember thinking two things that proved to be completely wrong. First wrong thing, “I’ve had water up my nose before, it can’t be that bad.” Wrong, totally wrong. Second wrong thing, “I won’t really become disoriented when we’re inverted. Worst case, I’ll release some bubbles and watch which way they go.” Ha! There’s a big difference between a little water in the nose and a gallon of water filling your entire head. Worse still, there’s just not much you can do about it because you need every molecule of air you’ve managed to suck into your lungs and frankly, you’ve got bigger fish to fry right at that moment. The disorientation I experienced after crashing, sinking and rolling over 180° is more complete than I could ever have imagined. Up and down, right and left became unbelievably abstract concepts. My next breath of air was about 10 feet away and between me and it was a closed door, a door latch, pounds of pressure resisting the opening of the door and a tightly fastened seat harness. Egress must be reduced to the basics. Graphic courtesy of MSTC into the cockpit via the controls, the pilot not in control should remove his or her hands and feet from the controls prior to landing. Feet should be placed flat on the deck with the knees squeezed tightly together. Fold your arms across each other with your hands grasping the shoulder harness or shirt high up on the shoulders. If you have a headrest, press your head back into it. If not, lower your face into the cradle provided by your folded arms. This position helps keep your limbs from flying about and gives added protection to the chin and face. Basic one Keep your safety harness or seat belt system on until the helicopter is submerged and rolled over. The only frame of reference you can possibly keep in your mind during a roll over is the original relationship you had with the door or exit when you first strapped yourself in. The only way to preserve that relationship is to keep yourself strapped in. If the door was on your immediate right when you took off this morning, then it is still on your immediate right. Staying belted in is counter intuitive. You will want to unbuckle and get out immediVol 3 Issue 1 ately! But, you won’t be able to fight the in-rush of water, nor will you be able to force the door open against the sea, assuming you can find the door, unless you have the additional leverage afforded by your harness. If you become nearly weightless, floating about the cabin, and the door is securely weighted by ocean—who do you think is going to win that tug of war? Five or six turns in ‘The Dunker’ will convince you of this. Basic two Reference the location of the door handle or exit release in relation to your body not in relation to notions of up or down. For example, the door handle is along my leg, half way towards my body from my right knee. Or, the emergency window is about an arm’s length forward from my left shoulder. During the pre-flight, you will already have memorized these locations and the operation of the release mechanisms. Learn to find and operate the release by feel, not with your eyes. Basic three Escape by the numbers. (1) Remove your hands from the brace position, finding the door handle with the appropriate hand and placing the other on the release for the seat belt. (2) Release the door handle and push the door open with the one hand. (3) Then, release the seat belt with the other. (4) Put both hands on the door frame and forcefully pull yourself through. One of my escapes involved pushing out the emergency exit window on an S76. This was the only time that I felt the beginnings of panic. I pushed, slapped and pounded on that window and it refused to budge. I was rapidly running out of air and seriously running out of confidence. I had one last try left in me and my brain screamed inside my head, “Open that &%$ *# !% window!” With one final furious push it was out, and so was I. When I got to the surface, more than a little relieved, Terry said to me, “When you’re using an emergency exit, don’t play patty cake with it.” Get mad! We’re out, now what Once out of the aircraft, hopefully with life vest inflated, there are a number of general rules to follow. The details depend upon many factors: temperature and sea conditions, likelihood of a quick rescue, T itle 14 of the Code of Fed- equipment availeral Regulations (14 CFR) able, etc. has a lot to say about flight If there is fire over water.

This skills learned from experience. should temporarily push the flames and any harmful liquids away from the immediate location while you grab a breath. If you don’t have a life vest, you can artificially create one using a shirt or overalls. First, button the top button on the shirt, then unbutton the next one down. If possible, tuck the shirt into your pants. Then put your mouth down to the unbuttoned opening in the shirt and place several breaths of air into it. A bubble of air should form in the back shoulders greatly adding to your buoyancy. Gather and hold the shirt front tightly to prevent air from escaping around the back of the neck. By continuing to form a tight band around your neck, the shirt can hold air quite a while. I did this and it works like nobody’s business. Take inventory of what you have available that may be useful and throw nothing away. If you are in a group, stay together. Preferably, huddle together by interlocking arms or waists. You’ll present a larger target. If someone in the group is injured, form a tight circle and put them in the middle. This will help keep them buoyant and with the group. If the water is cold, everyone will be warmed by forming a tight group with someone in the middle. Remember, you must be BIGGER, BRIGHTER or dIfFeReNt to be seen. Not til the fat lady sings Surviving in the water for a long period of time is determined by will almost as much as training and equipment. It is frequently more agonizing and difficult to be a survivor than it is to be a victim. Both Terry and Senior Instructor Kathryn Pumford, an 11 year MSTC veteran, continually remind us, “Your emergency is not over until you have been picked up 73 and are safely on board a rescue vehicle.” Sighting a potential rescue vehicle is not cause to abandon the plan that has held you together so far. Do everything you can to make yourself seen, but neither let down your guard nor surrender your plan until you are completely out of danger. deep inside a reclusive sinus cavity. Deftly raising my napkin to my nose while scanning the nearby tables to see if anyone noticed that I had a faucet in my head— I just had to smile. A little embarrassment, a wet napkin, and a two-day headache were a small price to pay for the invaluable skills acquired at MSTC. + The nose knows Later that evening, after a hard day of near drownings, I treated myself to a nice dinner in an exceptional Italian restaurant in town (Bella Figura—I highly recommend it). I was sipping on my espresso, eating my last bite of Tira Misu, when all of a sudden the flood gates opened and I was surprise attacked by about a half cup of water that had been lying in wait We covered a lot in this article, and hopefully, you’ll find it of value. But, there’s nothing like a day at MSTC and a tour of duty in ‘The Dunker’ to really prepare you for the rigors of underwater egress and water survival. If you have a chance to attend the MSTC training, you’ll find the costs reasonable, and I highly recommend it. You may contact MSTC at 337262-5929, or e-mail them at [email protected]. For more information go to http://www.louisiana.edu/infotech/MSTC/ PHPA–an interview with the president S o, who or what is PHPA? To answer that, I’ve turned to the source, the President of PHPA, Butch Grafton. I sat down with Butch in the bar of the Mariner’s Hotel one cloudy, drizzly, cold afternoon in Stavanger, Norway, a key city in Norway’s offshore operations, and asked him all of the questions I had about PHPA. I think they’ll be the same ones most of you will have. Tony: “Butch, what exactly is the Professional Helicopter Pilots’ Association?” Butch: “The Professional Helicopter Pilots’ Association, let’s just call it PHPA, is a nonprofit organization of helicopter pilots working for the good of all helicopter pilots. For as long as I can remember, helicopter pilots have been a rugged group of individuals going about their own business quite independently. There’s nothing inherently wrong with this and it suits the personalities of most helicopter pilots I know. Our independence, if you will, is also fostered by the way we work. We are clustered 2 8 into a dozen or so very different industries and very little crosspollination occurs across industry boundaries. But, there’s a price to pay for all our independence.” Tony: “For example?” Butch: “Many lessons go untaught because we don’t share what we do and what we’ve learned with other pilots. Our collective voice goes unheard in many areas where we should have a lot to say: safety issues, regulatory issues, and equipment issues.” Tony: “That may have something to do with the fact that we don’t have a collective voice.” Butch: “Exactly right! PHPA is creating a place where helicopter pilots at all levels from all industries can share what they know and pool their interests and voices into one that can be heard—one that can make a difference. And, it’s really very interesting to swap stories with peers from around the world— people doing similar things, but yet, doing them very differently.” Tony: “Exactly how did PHPA get started? I understand the idea was conceived in Madrid.” Butch: “Here’s how I ended up in Madrid. I was standing in the hall outside my office at Ft. Rucker, flight bag in hand, having just returned from a training flight with a couple of Army students when I looked into our office and saw a friend on the phone. He looked at me, lowered the phone and asked, ‘Butch, do you want to go to Madrid?’ To which I replied, ‘Is it all expenses paid?’ He said, ‘yes.’ And off I went. I soon found myself representing the pilots at Ft. Rucker, attending an international meeting of helicopter pilots. There were a number of other U.S. pilots there: Bill Blume, John Bosch and Marco Cordon from Air Logistics and Al Duquette from PHI.” “So there we were, in the middle of Spain, listening to pilots from all over the world talking about things that were important to them: flying experiences, safety issues, job security, Vol 3 Issue 1 regulatory quandries... And guess what, those are the same things that are important to all of us. We all immediately thought, we really should be doing this on a much broader and regular basis. There needs to be an organization of helicopter pilots that promotes the views of the pilot and provides a platform to give them a voice. Shortly after returning home, we came up with the name, Professional Helicopter Pilots’ Association, and we’ve been running full steam ahead ever since.” Tony: “Profile the founders for me. Who are these people and why are they willing to put their time and energy into this? What’s in it for them?” Butch: “Bill Blume, from Air Logistics was key in putting the idea together. John Bosch, also with Air Logistics, has been pushing for our own magazine since day one and he got his wish with the purchase of autorotate. John now heads the Media Committee. Al Duquette from PHI chairs the Safety Committee and works with Jeff Smith from LSSI at Rucker on a number of our Flight Ops areas. All of us share a vision for the future of helicopter piloting. That vision is compelling and worthy of our time and energy. That’s why we’re all here.” Tony: “Tell us more about the vision. What does PHPA “Early meeting of PHPA founders and organizers” hope to accomplish and how will they go about it?” Butch: “PHPA’s goals focus around the needs of the helicopter pilot. Some of these we know about. We want to help facilitate the sharing of information so we can all learn from each other. PHPA wants to promote an atmosphere of professionalism. We are all highly trained, skilled people doing important, often dangerous work. A high level of professionalism is key.” “Our industry is relatively safe, but it can be safer. We want to gather information and data regarding safety issues and present that data where it needs to be heard—to other pilots, to the manufacturers, the operators, and the regulators. We also want to promote the opportunity for helicopter pilots to have satisfying and rewarding careers—this means working with each other and with the operators. We expect our pilot members to tell us what is important to them. We’ll follow their lead.” “PHPA’s ability to accomplish all of these things grows as our membership grows. The more pilots that choose to become part of PHPA, the more momentum we’ll have to be an agent of change and improvement. It’s as simple as that.” Tony: “My experience with helicopter pilots tells me that we’re usually not big on joining things. I also have seen, among my peers, a great reluctance to part with money. Why are people going to join PHPA?” Butch: “It would be mighty presumptuous of me to say that pilots are going to join PHPA. Pilots will make that determination for themselves. But, I am happy to say that early statistics from our website indicate that pilots are signing up in significant numbers and there are important reasons why I think they should.” “PHPA membership provides an opportunity to improve our industry, our jobs, and our lives. We should all be interested in that. I don’t know a single helicopter pilot who is not proud to be doing what they do. Let’s put a little bit of that pride and honor we share into something larger than ourselves. PHPA membership also provides some immediate tangible benefits as well. Each member receives an annual subscription to autorotate. You’re proud of autorotate and we are too. It speaks to the pilot. As you know, we’ve also put the archives of autorotate on line so member pilots can do a search and receive information from over 100 articles.” 93 “Members also receive an annual subscription to Heli-Ops. It’s a great looking publication that pilots enjoy reading. There’s also a $1,000 Life Insurance Policy; a half hour of aviation legal consulting; and a very cool Professional Helicopter Pilots’ Association hat and bumper sticker. There’s an opportunity to participate in important committees and to share information with each other on our forum. One of the most important benefits is our resume service where we help pilots get their resumes out to prospective registered employers.” not make sense for everyone. Making a decision whether or not to organize is something strictly determined by the pilots involved. If some pilots are interested, we have a link on our website so they can find out more information.” Tony: “Who is eligible for membership?” Butch: “PHPA welcomes and encourages all helicopter pilots to join from every country and every walk of life. That includes military, students, private pilots, instructors and, Tony: “Quick change in of course, commercial pilots subject. Is PHPA a union organifrom all industries.

Rucker, I belong to Local 102. I would not say that I was pro-union when I arrived at Rucker, but for certain situations, I am now. However, I am emphatically pro-pilot. In some environments, Ft. Rucker being one, organizing the pilots has resulted in much improved safety conditions and career satisfaction for the pilots. By the way, Ft. Rucker has been organized for 28 years. The helicopter industry is a strange duck. Many operators are very small businesses with the owners doing a lot of the flying themselves. Unionization may 2 10 Butch: “Membership in PHPA is not mutually exclusive with participation in any other organization. We welcome pilots who belong to H.A.I., A.L.E.A. (Airborne Law Enforcement Association), and anywhere else.” Tony: “One more thing. You probably need to say something about Norway.” Butch: “Right. We are in Norway at the invitation of the International Federation of Airline Pilot’s Associations, also known as IFALPA. IFALPA represents pilots from most of the world’s major carriers, but also has a helicopter sub-committee, the same committee meeting I attended in Madrid in 2000. Helicopter pilots from Spain, Norway, the U.K., A utorotate is back and we’re delighted to be here. There are some important differences and some important nondifferences I want to tell you about. Let me confuse things just a bit more by addressing these in reverse order. First, what hasn’t changed. Autorotate, one of the few publications written exclusively for the pilot, remains, exclusively for the pilot. The content of the publication, as always, focuses on issues of interest to all of us: safety in flight, shared learning experiences, flying in different industries, extreme conditions, etc. We’ll continue to use a content rich, pilot friendly format. In short, we’ll continue to be autorotate. Switzerland, the U.S., literally all over the world, get together to discuss and recommend solutions to shared issues.” Tony: “In fact, I’m doing a story in the next issue that explains more about this. I think that’s about it Butch. We’ve covered some important ground. If someone reading this has some additional questions, how should they go about getting some answers?” Butch: “Probably the fastest way is to go to our website, www.autorotate.com, go to Contacts and send me a message. I’d be happy to get back to them on it.” Tony: “Autorotate.com— sounds familiar. Alright, enough work for now. Let’s go get something to eat. Did you bring an umbrella?” + Vol 3 Issue 1 Back in the right seat again What’s different about autorotate? I’m very happy to say we’re now part of something momentous—something with the potential to positively impact helicopter pilots everywhere. Autorotate has become the publication of the Professional Helicopter Pilots’ Association, PHPA. So how did this come about? When autorotate ceased production in August of 2001, we received well over 300 phone calls, e-mails and letters from friends and well-wishers. I was very touched and moved by these and I’d like to take this opportunity to thank those of you who took the time to let us know how much you appreciated the publication. But, life goes on. In my case, I took on some flight instruction responsibilities at a local flight school while I probed my options. It was a constructive break that I used to catch up with friends and family and regroup for the next phase of what has always been an interesting life. Then, one day last February, I got a call from Butch Grafton, representing the Professional Helicopter Pilots’ Association. Butch told me that PHPA was a new non-profit organization attempting to pull helicopter pilots together in much the same way AOPA has united general aviation pilots. And, he adds, they want to have a publication of their own. Would I be inter- When turbines explode I t was my first day back in my loggin’ helicopter following a ten-day break, and I was a bit worried about what I might find (or might not find, in this case) lying on the hillside. I had left over a dozen overweight logs lying there, but they were gone! I deduced in my Okie brain that either a UFO had come along and hoisted them away (for some deranged cellulose experimentation, perhaps) or they had been bucked (re-cut) and flown to the landing. Or, worst-case scenario, my relief pilot had done what I couldn’t do, in this very aircraft. And at 7000 msl in the dog days of summer...Yikes! To put my dilemma in perspective, the average Bell UH-1 can dead-lift 4000 pounds at sea level on a cool day. More if the wind is blowing 20 knots or so and the fuel cells hold mostly fumes. More if you simply toss the operator’s manual out the convenient hole in the bubble window, slide your brain into a bell jar, and put your spurs on. Does the term “Wenatchee Snatch” ring a bell? Not for the faint at heart! I actually had an owner operator tell me once that such a Bell could “pull six [thousand] pounds if you’ve got the guts!” Mondo guts, poquito brains, my friend! This particular Huey was my favorite. It had been ested in talking to them about autorotate? Duh?! And here we are. Well, not exactly. There were dozens of phone calls, a trip to New Orleans, a trip to New York and yes, even a trip to Norway before we got here. But the good news is, we got here. My thanks to Butch and PHPA for allowing me to continue the dream—providing a high qualilty publication dedicated to helicopter piloting. But, even more importantly, I thank them for offering a new vision—helicopter pilots from around the world, across different industries learning from each other and working together for the betterment of all. + By Dorcey Wingo in the capable hands of an ace mechanic during this work rotation, and I trusted him. When it came to matters of go or no-go, “Steve” (not his real name) had always given it to me straight since our first assignment together on an Aerospatiale Llama over 15 years before this assignment. Steve had a big smile waiting for me when I drove up early that morning, but he quickly relaxed his welcome face and dropped the other shoe. Our Bell’s engine was drinking turbine oil. Just under one quart an hour was technically within limits, but the oil was also running darker than usual. I reminded Steve that the big Lycoming had been consuming less than a quart per day when I went on break! Steve also remembered that I had declined to fly the big logs, leaving them for the sawyer to buck up. Steve had been on the phone to our maintenance chief many miles distant from our central Idaho location, sharing the day-to-day progress of the helicopter’s T53-13B engine. The chief assured us that another 13 engine was “in the can and arriving in two days, so watch that oil consumption and keep on loggin’!” Watch the consumption—unnecessary advice from a guy who flies a desk for a living. 113 The engine started up just fine and the cool morning air was delicious. But the low temps promised to burn away by ten o’clock and by then we’d be “suckin’ mud,” as they say. Too hot to be productive. Unless the wind came up, in which case we had a reprieve and could probably get in a complete day of logging—around eight hours of flight time. As I worked my way through the hooker rotation, taking three or four turns from each man on the fire salvage sale, I knew eventually I’d be coming to “Toby” (not his real name), the very hooker who had once hooked me up to a few of the big logs, back when. Toby was finally 150 feet below me, cramming choker eyes into the 80 lb remote hook, sending out beautiful three-to-six log turns. I eventually asked, “Hey Toby, I see the big pickles made it to the log landing, how many did you have to buck?” And to my amazement, he responded, “Not a one, pal! Dick [not his real name] flew ‘em all to the landing, no problemo!” I’m getting a bad feeling here. Each time I had tried to pull one of those big logs into the air, the engine gas producer raced to 101.5% N1, the exhaust gas temp (EGT) needle kissed the red line, yet all of this turning, burning, and body English produced only 40psi torque. (I needed 50 psi to get the big wood up). The rotor rpm quickly drooped, and the heavy turn settled to the ground a little closer to the log landing, but no cigar. And the wind was blowing pretty good that day! “Time for a chain saw,” I had advised Toby, and off I clattered in search of turns the aircraft would fly within limits. To have the peace of mind necessary to make a living logging with single engine helicopters, a pilot must believe that his logging-pilot peers with whom he shares the aircraft adhere to the same rules that he does. Rule Number One would go something like this: “Keep the Damned Thing within Limits!” So I had to tell myself that Dick simply was a better pilot by getting those big logs to the log landing. “Now wait just a danged minute!” my Okie brain hollered back at me! I’ve been doing this for quite a while! I probably had around 9K hours by then and well over half of that was long line work, heavy loads. I had loaded hundreds of log trucks. I knew the score. A spade was a spade. The day grew hot, as expected, and soon the ol’ bird was laboring. A flickering master caution light caught my eye suddenly and I noticed the engine oil pressure gauge was a blur. Oil temp was okay, but I called out the problem over the Wulfsberg and 212 headed to Service LZ, about 1/2 mile distant, dividing my attention by scanning the panel and searching for a spot to put the bird down. Made it to the LZ and Steve was waiting for me. After shutdown, Steve pulled the engine oil filter screens and found them to be fairly coked up. Another call was made to the desk wizard, and based on Steve’s description, the wizard directed Steve to blast out the screens with solvent, replace them and run the engine for several minutes, which we did. No flickering oil pressure gauge? “You’re probably good to go,” advised the wizard. Remembering that we had had some small paychecks recently, off I floundered back into the sticky air, the 150-foot line dangling between my skids. I made a note to myself at that point that Steve’s deodorant was beginning to fade. Check that. It was me! A little over a half hour later, after gently dropping a turn at the log landing and radioing “Coming to Toby,” there was the flickering oil pressure gauge again! Rats! “I’ve got the problem again,” I radioed, “Heading for Service!” I stole a peek at the bubble door panel while I had a second, and the large amber master caution light glared back at me. I reset it. It was dark for a second, then came right back on. Not a good sign. Before I could scan right to verify the problem segment on the master caution panel, something I’d never seen before caught my eye! The EGT needle was climbing past the 610 degree C red line and headed straight for the peg! It was around then that I noticed a distinct odor of burnt oil and a new sound growing in volume behind me, a distinctive rumble that made the hair on my neck raise up several degrees. My Okie ancestors were trying to tell me that the durned turbine was about to take a crap. I keyed the mike again, “I’m gonna have to put her down right here!” To which the little blonde lady at the log landing radioed back, “You’re on fire!” Now I know she meant well, but I was still two hundred feet in the air, over rough terrain and was trying to sort out the best route around some tall snags and find a place to plant the ship...and she had to go and say that! Punching off the long line just outside the loglanding perimeter, I hastily descended for the sloping hillside ahead of me, snags, stumps, boulders, and all. I’m pleased to tell you that the engine held power all the way to terra firma, although she was rumbling and must have looked mucho unairworthy to the observers on the log landing. The left skid barely missed a stump on the down-hill side and the right skid kissed Vol 3 Issue 1 a boulder uphill, but no rotor strike! So there I was back on the ground and it was beginning to look like I was gonna make it home to Momma one more time when the little blonde lady radioed, “Get your ASS OUT of that thing, you’re on FIRE!” But I still had hold of a wounded Huey that was trying to slide sideways down a 15% slope. I had a throttle to turn off, likewise the fuel and battery switches and the steepness of the left-skid-low slope was pulling my upper body into the bubble door, making up-slope house-cleaning chores difficult. Imagine my dismay when, with the throttle rolled to the cut-off position and the fuel switch flipped to OFF, I heard the unmistakable sound of the compressor dramatically sucking air into the engine...the engine rpm began to accelerate toward oblivion! [Blondie ain’t seen nothin’ yet] The rotor systems for all my stuck-wing friends, is mechanically linked with the engine for this mad dash to hell, so I quickly began to fear that main rotor break-up was imminent! I recall involuntarily pulling my head into my shoulders like a turtle as the incredible sound of the out-of-control enginerotor system screamed upward to a crescendo that could only end in a violent explosion. Ear plugs in place, everyone? KAAAAAAAAA-BLOOEY!!!!! The explosion sent about twenty hookers, cutters and other woodsmen (mushroom pickers, tree huggers, & little blonde ladies) running from a mile around in my direction. I was still getting my harness unbuckled and you could probably have seen hundreds of little question marks hovering over my head like a cartoon as I scrambled out the door and down the hill, taking giant strides, wondering what the heck...and relishing the relative quiet of the rotors swirling behind me. (They were whistling weirdly for some reason!) Once I had run a hundred feet or so, I spun around to see an oil fire raging on the engine deck while more flames were dripping over the side of the fuselage, catching the paint on fire. I yelled to the landing crew to grab some fire extinguishers and I raced back up to the ship, thinking how stupid it might appear, but I wasn’t about to watch this bird burn after bringing me safely back to earth! In seconds, the ship’s little 5-lb extinguisher was played out but just in time came the landing crew, two of them carrying 10 lb Halogen fire bottles, which did the job. Five full minutes passed as my old loggin’ buddies came running up, swapping expletives and staring in wonder at the football sized smoking hole atop the engine, where the turbine wheels had exited straight up into the rotor system! I was hacking up my third Halogen hairball when I noticed that down between my sneakers and the woods boss’s corked boots, a wisp of smoke had just popped out of the forest duff! At about the same instant, we were almost run over by a group of around ten woodsmen lugging backpack water sprayers, who were headed uphill and totally ignoring us. We looked over the tops of their hard hats, past the distorted remains of my engine, the rotor blades pierced completely through numerous times by turbine wheel fragments. Several hundred feet up the hill, smoke was billowing up into the tall Douglas fir. I had started a damned forest fire! The rest of us began stomping out five or so littler smokes that had popped up near the Huey in the last thirty seconds, started by tiny shards of red-hot turbine wheels. Then came the water-dropping helicopter! Piloted by none other than the afore-mentioned relief pilot, who happened to be logging with our sister crew nearby. Dick had heard the commotion over his Wulfsberg. He and his mechanic did a quick job of converting his K-model Bell from a logging-ship-tofire-fighter, flying a 300-gallon Bambi bucket down to a deep blue lake only a minute away. Now Dick was the hero, putting bucket after bucket of cold mountain lake water right on the money, plus a little mist wafting our way to help cool us off. I was feeling the irony of the situation, big time. I looked up and gave him a thanks-now-goaway gesture as he blathered off down the hill. He didn’t come back. End of story. Well almost: an analysis was months in coming from the desk guy, but common sense and a good friend who really knows his engines had long before determined that the turbine blew an internal seal, allowing engine oil to flood directly into the red hot burner section. The oil instantly converted into tremendous energy and sped the gas producer and turbine wheels on their way to a catastrophic break-up. Epilogue: Lucky me! I’ve since made a promise to my significant other that I will never ever fly any helicopter that Dick has so much leaned up against. + 13 3 So that’s how that works 2 14 a solenoid for the remote or automatic switching of current in one circuit, using a current from another circuit. In other words it’s a switch. Relays are used throughout a helicopter’s electrical system to provide over voltage protection, reverse current protection and to simply open and close electrical circuits. The significance of these two electromechanical devices as they pertain to the design of helicopters is the fact that they save significant weight over simple mechanical devices that are commonly used on other machines to do the same job where weight is less of a factor. Where this becomes really evident is in the use of relays. It is my experience that most helicopters employ another weight saving practice when it comes to the electrical system. Electricity, to be useful to us, must have a circuit or in other words a path to and from each electrical device. In most helicopters a single wire is used to bring electricity to a component and the fuselage is used to bring the electricity back to the source completing the circuit. The fuselage would be referred to as the ground. Now we know that the majority of switches that are used to turn on and off most of the equipment in the helicopter are in the cockpit within the pilot’s reach. In many helicopters the engine and primary electrical compartment are located some distance from the pilot’s station. Many components we use such as starters and generators require heavy gauge wire to carry their large currents. Since like we said, the switches to control these things are in the cockpit, one could assume that these large heavy wires run all the way to the front of the helicopter to the switch and then to the device. But, if you have ever had the opportunity to look behind your panels you would have noticed that in fact this is not the case. You probably noticed tiny little thin white wires running to the back of all those switches. These switches only need handle the small amount of electricity used to open and close the big heavy-duty switches back in the electrical or engine compartment, which we said earlier, are relays. In this way we are able to reduce the weight of the wiring harness of a helicopter. Heavy cables required to carry large electrical loads are kept as short as possible by using relays to open Graphic courtesy of Encyclopedia Britannica I n 1480, Leonardo Da Vinci wrote in his Codice Atlantico; “...I have discovered that a screwshaped device such as this, if it is wellmade from starched linen, will rise in the air if turned quickly...” Yet it would not be until 1907 that Frenchman Paul Cornu would take off vertically in a machine we would recognize today as a helicopter. There were many necessary technological advances that needed to take place for the dream of hovering flight to become reality. Many would argue that the most significant invention that made helicopter flight possible was the invention of the internal combustion engine during the late 1800’s. Although the power to lift a machine and a pilot into the air became possible, this was a long way from a flying platform that would prove useful for anything more than amazing on lookers. In actuality, there are numerous unique materials and devices that would be brought together to produce the first useful helicopter. As a helicopter instructor pilot I routinely point out individual parts and pieces to my students during our daily preflight. Admittedly, my knowledge of what some things do is at times rudimentary at best. So it is my intent to look at a few of the “gizmos” and “thing-a-mabobs” that are installed in most helicopters and try and understand what they do and how they help us do what we do better. I would like to start my discovery tour by looking at an electro-mechanical device known as a solenoid. A solenoid is made up of a coil of wire and a cylindrical plunger. When a current is passed through the coil a magnetic field is created which produces an electromotive force on the plunger. The movement of the plunger may be used for numerous purposes throughout your helicopter. For instance, solenoids are commonly used to open and close fluid valves as in the case of a fuel or hydraulic solenoid. Solenoids are also often used as remote switches and to open and close relays, which brings us to our next topic; relays. What exactly is a relay? I know my electrical compartment is loaded with them, but what do they do? Interestingly enough, relays employ solenoids. A relay is an electromagnetic device which employs by Andrew Palmer Vol 3 Issue 1 and close the circuit close to the device. We control the relay by running a lightweight wire for the small electrical load to a switch located in the cockpit. So there you have it folks. By passing a little electricity through a coil we can make something move. We package it up in a little canister and we call it a solenoid. Solenoids come in many shapes and sizes and can be used to open close valves, to prevent your throttle from being closed inadvertently in flight and to open and close relays, in addition to many other nifty things. Relays are big powerful switches controlled by little lightweight switches. Without the use of relays and solenoids, the helicopters we fly would be much heavier. In our business additional weight means fewer passengers, less cargo or less time we can stay in the air, which in the end means less capability to get the mission done. Thank goodness for the inventiveness and genius of men like Da Vinci, that each day technology takes another step forward. + NTSBs T he following information was extracted from the NTSB files. This information was edited for available space and is subject to change as investigations continue. Reports were selected based on importance of the information to the broader helicopter industry. Schweizer 269C; Phoenix, AZ May 13; No Injuries On May 13, 2001, about 1040 MST, a Schweizer 269C made a hard landing on the desert floor, and rolled over on its side, while practicing autorotations near the Phoenix Deer Valley Airport (DVT). On the way back to Scottsdale Airport (SDL) [the instructor] took the flight controls from the student to demonstrate an autorotation. During the autorotation the CFI stated that he was unable “to get enough rpm during the flare.” He attempted to recover from the autorotation by leveling the helicopter; however, the helicopter landed hard. He stated that because of the uneven terrain the helicopter flipped onto its side after touchdown. According to the student; they were headed back towards SDL when the CFI took the controls from the student. The CFI then did a “quick stop” (no forward airspeed) and dropped the collective. The student remembers the CFI simultaneously stated, “watch this” after he lowered the collective. He noted that they were about 400 feet above the ground (agl) when the CFI started the maneuver. The student stated that because of the weight and density altitude the airspeed bled off and the helicopter started to turn in a circle and “dropped like a rock.” About 200 feet agl, the student stated that he realized they were going to crash and went to raise the collective. He stated that the collective was in the full up position. He also noted that the airspeed was at zero and the rpm needles were joined and read 2,000 rpm. The student reported that the helicopter made a 360-degree turn prior to hitting the ground. The helicopter bounced into the air and then came to rest on its right side. R-22 Mariner; Merlin, OR, May 23; 2 Fatal Injuries On May 23, 2002, approximately 1545 PDT, a Robinson R-22 Mariner was destroyed after it collided with service lines and terrain near Merlin, Oregon. The commercial pilot and passenger were fatally injured. Visual meteorological conditions prevailed and no flight plan was filed. The flight originated from Grants Pass, Oregon, approximately 15 minutes prior to the accident. A witness reported that the helicopter was traveling northwest bound over the Rouge River. He reported that as the helicopter was transitioning the area, it collided with a series of pole-mounted service lines that traveled perpendicular the river corridor. Shortly after contacting the services lines, the helicopter impacted terrain. Bell 47G-4A; Yauco, PR May 25; Injuries: 1 Fatal, 1 Serious, 1 Minor On May 25, 2002, at 1240 EST, a Bell 47G-4A, helicopter collided with two parked automobiles and burst into flames as the pilot attempted a precautionary landing in Yauco, Puerto Rico. The helicopter was destroyed. The owner/passenger was fatally injured, the center-seated passenger received serious injuries, and the private pilot received minor injuries. According to the pilot, while enroute to the destination he noticed a reduction in engine power and a reduction in engine oil pressure. At this point the pilot decided to make a precautionary landing... He selected a landing area near a restaurant. The pilot reported that after touchdown in the parking lot, the helicopter started to slide rearward. The pilot stated that as he attempted to position the helicopter away from the automobile, the main rotor blades struck the parked vehicles and the helicopter and the vehicles burst into flames. Examination of the accident site showed that wreckage debris was scattered over an area approximately 100 feet long and 40 feet wide. The examination also revealed that the initial touchdown point was on a steep upslope in a confined area. Further examination revealed that one main rotor blade was torn from the main rotor head and was not fire damaged. The fuselage sustained extensive fire damage. 15 3 Bell 206L-1; Meadview, AZ May 28; 1 Minor Injury On May 28, 2002, approximately 1045 PDT, a Bell 206L-1 was destroyed when it impacted terrain while on landing approach in the Grand Canyon approximately 15 miles east of Meadview, Arizona. The commercial pilot, the sole occupant aboard, received minor injuries. According to a Federal Aviation Administration inspector, the accident occurred on the third flight of the day. The helicopter had been operating as a non-scheduled domestic passenger flight. “Papon 10” transported three passengers to the bottom of the Grand Canyon and returned. Two more passengers were then transported to the bottom of the Canyon, and the original three passengers boarded and were brought back. The helicopter returned to get the other two passengers. On its landing approach, the helicopter struck a hillside, bounced on its skids for 60 feet and cartwheeled, coming to rest on its left side. According to the aircraft loader who witnessed the accident, there was no change in the engine or rotor sounds. OH-6A; Angola, NY May 29; 2 Minor Injuries On May 29, 2002, about 1000 EDT, a Hughes OH-6A helicopter was substantially damaged while landing at a private airstrip near Angola, New York. The certified flight instructor (CFI) and student pilot received minor injuries. According to the CFI, the helicopter departed the Sheriff’s Heliport in Hamburg, New York, about 0930, with the student pilot at the controls. The CFI instructed the student to perform a high “recon,” followed by a low “recon” while in a left hand pattern, in order to inspect the intended practice field. On the last circle over the grass strip, the CFI requested the student to gain altitude from 1,100 feet msl, to about 1,500 feet msl, due to terrain. The CFI then requested that the student conduct a normal 216 approach to the runway midfield, and terminate to a hover. The CFI recalled that the gauges were in the normal green range as the student setup for the normal approach. The approach was into the wind, at an airspeed of 65-70 knots. At the decision height, approximately 75-100 feet above the ground, the CFI observed the student starting to bleed off the airspeed by pulling aft on the cyclic. The helicopter then abruptly made an uncommanded yaw to the left, and began to roll. The CFI observed the rotor tachometer “ bleeding off,” and did not see the engine needle on the left hand side of it’s gauge. The CFI assumed control of the helicopter. He proceeded to lower the collective just enough to try and maintain glide, while applying forward and right cyclic to counter the left roll. About 30 feet above the ground, he applied aft cyclic to flare, and then forward cyclic to level the skids. The helicopter touched down on the skids, level with the ground, on the side of the grass strip. The helicopter skidded forward about 50 feet, into a culvert ditch, where it came to rest. Inspection of the wreckage by a Federal Aviation Administration inspector revealed that the tail boom separated from the fuselage, and substantial damage was sustained to the rotor blades. Bell 206; Columbus, OH May 30; No Injuries On May 30, 2002, at 0930 EDT, a Bell 206 helicopter was substantially damaged during a practice touchdown autorotation at the Ohio State University Airport (OSU). The certificated flight instructor, and airline transport pilot were not injured. According to the pilot receiving instruction, he and a Bell Helicopter employed flight instructor were scheduled for a training flight on the day of the accident. The two pilots completed the preflight, and then boarded the helicopter. Once airborne, the pilot climbed the helicop- ter to 2,000 feet agl, and completed three autorotations. All three autorotations terminated at altitude with a power recovery, and during the maneuvers, rotor RPM remained within normal operating limits. Satisfied with the autorotational characteristics of the helicopter, they returned to the airport to continue the training. The pilot first performed a normal approach and progressed to autorotations. The pilot had completed approximately eight hovering autorotations, and six touchdown autorotations prior to the accident. The accident autorotation started with the pilot executing a normal approach. During the approach, while the helicopter was descending through 300 feet agl, the instructor rolled the throttle to idle. The pilot lowered the collective and entered an autorotation. At first, he did not think he was going to make his intended touchdown point, and wanted to increase airspeed, but the instructor told him to slow the helicopter to 50 knots. The pilot applied aft cyclic, and airspeed decreased to about 40 knots. The pilot was now sure he would not make his intended touchdown point by maintaining 50 knots, so he lowered the nose. As airspeed increased, the pilot realized he was going to overshoot, so he initiated a left, and then a right turn to lose altitude. The pilot initiated a flare, applied initial collective, and then used additional collective to cushion the landing. Rotor RPM decayed during the landing sequence, and the helicopter touched down hard on the aft part of the skids. The pilot then instinctively applied aft cyclic, which the instructor was unable to prevent. The helicopter came to rest upright, and the pilots exited under their own power. Examination of the helicopter revealed substantial damage to the tailboom, and main transmission mounts. Rotorway 162F; Tampa, FL June 03; 1 Minor Injury On June 3, 2002, about 2130 Vol 3 Issue 1 EDT, a homebuilt Rotorway International 162F crashed onto the roof of a house near Tampa, Florida. According to one witness, she first heard a helicopter then observed the helicopter circling and observed what she thought was the pilot lose control of the helicopter. She reported seeing the helicopter spinning quickly around the axis of the main rotor, and when that happened she heard the “blade” noise increase to a very deep loud pitch. The helicopter then lost altitude but returned to a slow circle. She reported that the described events occurred twice and it appeared to her that the pilot would regain control but would lose altitude. The helicopter disappeared behind trees and she heard a sound associated with an impact. Post accident examination of the helicopter revealed that one of the two main rotor blades was bent down; the other blade was fracture separated approximately 6 Live and learn O n April 19, 2002, a broken aircraft, offshore in the Gulf of Mexico, was waiting on me to bring Pete, a mechanic, and a part to complete repairs. I was to fly from Houma, LA to Fourchon, LA and then offshore to South Timbalier 145 where the other aircraft was waiting. My aircraft that day was a Bell 206L1, N3195P. We made the flight from Houma to Fourchon in 24 minutes with no problems. We picked up a part for the broken aircraft, added some fuel and hovered for takeoff. Fourchon has recently undergone significant expansion and has so many cranes, new buildings, and large boats that you can’t see daylight until three hours after sunrise. Takeoffs and landings in this area require heightened awareness to negotiate the obstacles. As we hovered out to depart, I paused and made the remark to Pete that due to the recent expansion we’d be “screwed” if we had an engine failure on takeoff. Mistake! Never tempt fate. I’m certain a gremlin heard my comment and began scheming against us. We departed Fourchon and leveled at 1000 ft. headed southwest and successfully left the labyrinth behind. We had flown about 4 miles from Fourchon, and had already crossed the beach outbound when I heard a bang. The aircraft yawed hard left. The engine out audio sounded (unpleasantly). The rotor plummeted to the bottom of the green, and then I caught it by entering an autorotation. During the auto, I quickly glanced at the gauges and saw that all the significant ones were pointed left—that’s not right! I maintained b.r.o.c. airspeed with the rotor in the low green to keep the descent rate low until I was ready to flare for landing. We were 200 lbs. under gross weight, and had less than feet outboard from the attach point. The separated piece of the blade was recovered. One of the tail rotor blades was separated and was not recovered with the helicopter; the remaining blade exhibited damage on the blade tip. Following recovery of the helicopter, both main rotor blades were removed and the engine was started and operated with no repairs made to the engine. + Crash course by Dave Lewis 5 knots of wind and the landing went well. It has been said by some, who fly a great deal, that recurrent training is useless. If so, it is the most helpful uselessness I practiced last year. Experience is the hardest kind of teacher. It gives you the test first and the lessons afterward. We landed safely, so I suppose I passed the test. However, now that I’ve had some time to think about it, there are a few lessons that I learned as well. First—communicate by the book. During the auto, I made 3 initial radio calls to our flight following facility. Not three mayday calls, three radio calls. Therein lies a lesson. Ever wonder how you’d react during your first engine failure? Everyone I’ve talked to so far has said that they reacted very calmly during their emergency…time slows down…you reflect on what happened afterwards. I also remained calm (-ish)…call it…urgent casualness. I took the event in stride. I established the auto, and then I calmly notified flight following: “95Papa has an engine failure.” Answer: “Say again.” “95Papa has an engine failure.” Answer: “Say Again.” “9-5-Papa…Has…An…Engine…Failure.” Answer: “Roger.” The significance of my message was not getting through. I only had 1000 ft to use, so out of frustration I used my other radio to notify local traffic that “95Papa had an engine failure.” Another aircraft understood my radio call. Somewhere during the 173 other aircraft’s response I heard flight following asking about my location (“Ah! Now they get it!”). I told them my location and then completed the auto. There was a communication problem—I was too casual. Flight following receives thousands of radio calls per day. They often get overlapping calls on the same or different frequencies. The flight following personnel were having difficulty understanding my transmission. From the time we’re old enough to watch television we’ve all been able to understand “mayday.” All pilots are taught to say it. Well, somewhere along the line I started mentally practicing my engine failure radio calls as just plain “aircraft such-and-such has an engine failure.” Even if flight following understood my message the first time, they would not automatically know that I was flying in a single engine aircraft. How would they know the gravity (pardon the pun) of the emergency? I’m thinking, what if I had been in a remote area with no time to make additional radio calls, and flight following wasn’t able to understand me? Next time I’ll say “mayday.” Second—one six pack isn’t always enough. Many Gulf pilots carry a “six-pack” with them to help during a water landing. A “six-pack” is the term Gulf pilots use for the six float packs attached to the skids of the aircraft. I had envisioned that in relatively calm water, like the 2 ft. sea state we landed in, one could land and float for hours waiting to be rescued. As it turns out, even if all of the floats inflate before landing (which doesn’t always happen), the floats are only intended to give you enough time to safely exit the helicopter. Even with the calm water we had that day, the back right float took a continuous battering for about 20 minutes and then decided to deflate. The aircraft slowly overturned in about a ten minute period of time. A higher sea state or a float pack that never inflated could have made our situation considerably worse. Now I know to anticipate the unexpected. Third—A little experience often upsets a lot of Test pilot 1.

I had always envisioned landing, quickly deploying the life raft, and safely exiting the aircraft in record time. What happened to us? We tossed our raft out the door, pulled the lanyard and presto; the raft inflated—upside down! (According to Murphy’s Law, the likelihood that your life raft will inflate upside down is directly proportionate to how urgently you need the raft.). The raft then proceeded to drift to the front of the aircraft, and the lanyard became entangled under the left-front float bag. Pete worked diligently for several minutes to recover the raft, and another few minutes to flip it over, allowing us to exit just a few minutes before the aircraft overturned. Again, I learned “prepare for the unexpected.” Incidentally, I never inflated my personal life vest—I was afraid of what might happen. Fourth—salt water may not be a better conductor. While Pete was working on flipping the raft I made a few radio calls. After a short time, I decided to make another call. I turned my radio back on, keyed the mike and……..silence. I really hadn’t considered this before, but there’s no law that says the radios must work for an extended period of time after a water landing. So, we were without the aircraft’s radios, though I still had an emergency radio in my life vest. Somebody later brought up the question, “What if there are no aircraft around and you must rely on the boats in the area for assistance?” “What if you end up waiting overnight for a rescue?” With all this in mind, it would be nice to have a marine radio. Personally, I’m checking into buying a handheld waterproof marine radio that I can carry in my life vest. This experience has equipped me for future emergencies by demonstrating that many unexpected events may take place after a successful emergency landing is completed. A safe emergency water landing may be the beginning of the entire event—not the end. + Quiz answers 1. a). AIM Para 3-13 2. b). Advection fog forms when moist air moves over ground or water.
