3. Engine Pre-operational Check
A. Procedure
(1) Remove the air inlet and exhaust covers (if fitted). Do not permit the propeller to windmill if
a restraining device is secured to the exhaust covers.
(2) Open engine cowlings (Ref. Aircraft Manufacturer's Manual) and inspect the engine mounts
and air inlet screen, and spray ring, if fitted.
(3) Examine all linkages to the engine and to the accessories mounted on the engine, for
attachment.
(4) Examine all fuel and oil tubes, lines and connections for security and for leaks. No leaks are
permitted except at normal seepage drains.
(5) Examine all pneumatic line connections and filters for
security.
WARNING: MAKE SURE THE ELECTRICAL POWER IS OFF.
(6) Examine all electrical connectors for proper
installation.
CAUTION: DO NOT MOVE THE COCKPIT POWER CONTROL LEVER INTO PROPELLER
REVERSE POSITION, AS DAMAGE TO THE LINKAGE WILL RESULT. REVERSE
MAY ONLY BE SELECTED WITH THE ENGINE RUNNING AND THE PROPELLER
TURNING.
(7) Check the cockpit engine controls for freedom of movement and verify full travel of engine
control linkages.
NOTE: Individual airframe installations may prevent full application of this check with the
electrical power off and engine not running. Refer to individual aircraft operating
instructions.
(8) Check engine oil level and that oil system has been properly serviced (Ref. 72-00-00,
SERVICING). Check locking of the filler cap after servicing.
(9) Close engine cowlings (Ref. Aircraft Manufacturer's
Manual).
(10)Make sure that fuel system has been serviced with proper fuel (Ref. Service Bulletin SB1244,
Approved Listing of Engine Fuel and Additives).
(11)If the engine is not to be started immediately, refit the air inlet and exhaust covers. If the
engine is to be started, remove the propeller restraining device. Check that the area is clear
for engine motoring.
