INTRODUCTION
The Aeronautical Accessories External Hoist Kit 412-140-XXX enables operations in areas
where landing cannot be accomplished.
The hoist can raise or lower loads up to 600 pounds (272 kilograms). An electrically actuated
cable cutting device allows pilot to sever cable in an emergency. A manually operated cable
cutter, accessible to the operator, may be used to sever the hoist cable if the electrical cable
cutter should fail.
The 42325–12 Hoist System has a three-sixteenth inch hoist cable with a usable length of
250 feet (76.2 meters).
The 42325–14 Hoist System has a three-sixteenth inch hoist cable with a usable length of
290 feet (88.39 meters).
1-3.
TYPES OF OPERATION
Hoist operations are approved for hoist loads up to 600 pounds (272 kilograms). See Hoist
Loading Schedules.
CAUTION
Hoist shall not be operated when other components are
loading the roof tiedown studs adjacent to hoist support
assembly.
Hoist operations must be conducted under appropriate operating rules for external loads.
The external load equipment certification approval does not constitute operational approval;
operational approval for external load operations must be granted by the local aviation
authority.
Hoist use approved for VFR only.
Hoist operations are approved only in hovering flight. The object being hoisted must be
completely in the cabin before forward flight is established.
1-4.
FLIGHT CREW

WEIGHT AND CENTER OF GRAVITY
1-6-A.
WEIGHT
AA–95033
Revision C
Actual weight change must be determined after hoist is installed and ballast readjusted, if
necessary, to return empty weight CG within allowable limits.
Maximum gross weight including hoist load is 11,200 pounds (5080 kilograms).
Maximum hoist load is 600 pounds (272.2 kilograms). This is a structural limitation only and
does not ensure that longitudinal or lateral CG will remain within approved limits. Maximum
allowable hoist load varies with gross weight, center of gravity, and hoist location. Refer to
appropriate Hoist Loading Schedule.
1-6-B.
CENTER OF GRAVITY
Butt line of load on aircraft equipped with low skid gear is 61.33 inches (1558 millimeters)
from centerline.
Butt line of load on aircraft equipped with high skid gear is 65.33 inches (1659 millimeters)
from centerline.
Select Hoist Loading Schedule appropriate for position in which hoist is installed. Enter
schedule at helicopter gross weight prior to hoisting. Proceed vertically to intersect
appropriate diagonal line representing number of crew members on board . Then proceed
horizontally to the left to read allowable hoist load.
The loading schedules labeled “With Hoist Ballast” represent allowable Hoist loads when
167 pounds (76 kilograms) of ballast is located at BL 40.0 left (1016 millimeters) to
compensate for the moment of the Hoist kit installation.
NOTE
The Hoist Loading Schedules are based on the most adverse
loading combinations of pilot, copilot, and hoist operator, each
weighing 170 to 200 pounds (77.1 to 90.7 kilograms) and on a
weight empty CG 0.5 inches to the right of centerline (+0.5) prior to
adding hoist. If lateral CG is appreciably different or if crew
member weights are out of this range, allowable hoist load shall
be computed. For computation, assume hoist operator is located
laterally at BL 40.0 (1016 millimeters).

SECTION 6: SYSTEM DESCRIPTION
The Aeronautical Accessories External Hoist Kit 412-140-XXX enables operations in areas
where landing cannot be accomplished.
The hoist can raise or lower loads up to 600 pounds (272 kilograms). An electrically actuated
cable cutting device allows pilot to sever cable in an emergency. A manually operated cable
cutter, accessible to the operator, may be used to sever the hoist cable if the electrical cable
cutter should fail.
The 42325–12 Hoist System has a three sixteenth inch hoist cable with a usable length of 250
feet (76.2 meters).
The 42325–14 Hoist System has a three sixteenth inch hoist cable with a usable length of 290
feet (88.39 meters).

Safety features for the External Hoist Kit are:
April 15, 2016
•
Hoist is electrically bonded to the aircraft and structurally enclosed to guard all moving
parts.
•
Safety Hook featuring a spring loaded latch mechanism with a positive locking feature
to prevent D Ring rollover and accidental disengagement from the hook.
•
A cable cutting system enables the pilot to cut the hoist cable in the event of an
emergency which requires the hoist load to be jettisoned.
•
A level wind mechanism ensures an even lay of cable on the cable drum and ensures
that the cable, at the point of exit from the external mounted hoist assembly, is always
perpendicular to the cable drum.
•
An installed slip clutch (load limit device) enables the cable to reel out automatically if
the cable load exceeds 1275 to 1530 lb. The slip clutch prevents damage to the
aircraft in the event of cable over load or accidental entanglement of the hook during
hoist operation.
