POWER PLANT
1. GENERAL
This chapter describes maintenance practices for the airplane systems which provide the means to induce
and convert fuel-air mixture into power such as the engine, baffling, cowling, mount, attach fittings, electrical harnesses, air intake, and engine drains.
2. DESCRIPTION
A. Engine
The airplane is powered by a Teledyne Continental IO-360-ES engine. The engine is a six cylinder,
horizontally opposed, fuel injected, air-cooled, wet sump, power plant incorporating a down01 May
2012 induction system, tuned exhaust, and provisions for front and rear mounted accessories. (See
Figure 71-001) (See Figure 71-002) (See Figure 71-003)
B. Baffling
Sheet metal baffles are installed on the engine to direct the air flow around the cylinders and other
engine compartment components. To help direct and contain air flow in the engine compartment, the
baffles utilize fiber reinforced silicon seals in contact with the cowling around the circumference of the
engine.

B. Engine Baffling (See Figure 71-004)
CAUTION:
Proper baffling installation and care is critical to engine cooling. If baffles or seals are
broken or misshaped, the amount of air flowing past a particular cylinder or component
will increase. The increased airflow in one area causes a reduction of airflow past other
components and leads to higher temperatures in some parts of the engine. Ensure baffles are installed correctly and seals fit and direct airflow in the proper direction.
Various lines, hoses, wires, and controls are routed through some baffles. Ensure that
these components are reinstalled correctly after baffle installation.
