Engine Operation
4-3.2. Engine Start
Refer to the aircraft POH for detailed engine starting procedures. Complete Section 4-3.1,
“Pre-operational Requirements” prior to engine start. Be familiar with the quantity and
location of the engine fuel system drains.
WARNING
Do not attempt to start an engine with an over-primed or
flooded induction system. Starting an engine with a flooded
induction system can result in hydraulic lock and subsequent
engine malfunction or failure. Allow excess fuel to drain from
the intake manifold and/or cylinder prior to attempting to start
the engine.
When starting the engine, ensure the battery is completely charged, especially in sub-
freezing temperatures.
CAUTION: Attempting to start an engine with a partially discharged
aircraft battery may result in damage to the starter relay or possible
engine kick-back resulting in a damaged starter.
Verify the tasks listed in Table 4-2, “Flight Prerequisites,” have been completed in
addition to those required by the aircraft POH, aircraft manufacturer, or Supplemental
Type Certificate (STC) holder. Note the following:
•
If the engine is being started in extreme cold, preheating may be required. Refer to
Section 4-5.1, “Engine Operation in Extreme Cold.”
•
If the engine is started in hot weather, refer to Section 4-5.2, “Engine Operation in Hot
•
If the engine is being started at high altitude, refer to Section 4-5.3, “Ground Operation
WARNING
Ensure the propeller arc is clear of personnel and obstructions
before starting the engine.

After priming, turn the primer handle to the “LOCKED” position to
prevent the engine from drawing fuel from the primer.
