EMERGENCY
NOTE
•
CAUTION: The pilot should determine the reason for engine failure before attempting an air start.
•
NOTE: Airspeed should be maintained at or above 100 KIAS to ensure the engine will windmill.
WITH UNFEATHERING ACCUMULATORS:
1. Fuel Selector - ON
2. Throttle - SET approximately 1/4 travel
3. Aux Fuel Pump - ON
4. Magneto/Start Switch - BOTH
5. Propeller Control - MOVE FULL FORWARD UNTIL ENGINE WINDMILLS, THEN BACK TO MIDRANGE. USE STARTER MOMENTARILY IF AIRSPEED IS BELOW 100 KTS.
•
If propeller does not unfeather or engine does not turn, proceed to WITHOUT UNFEATHERING ACCUMULATORS procedure.
6. Mixture - FULL RICH
7. If engine fails to run, clear engine by allowing it to windmill with mixture in the FULL LEAN position. When engine fires, advance mixture to FULL RICH.
8. When Engine Starts - ADJUST THROTTLE, PROPELLER, AND MIXTURE CONTROLS
9. Aux Fuel Pump - OFF (when reliable power has been regained)
10. Alternator Switch - ON
11. Oil Pressure and Oil Temperature - CHECK
12. Warm Up Engine (approximately 2000 rpm and 15 in. Hg)
13. Set power as required and trim.
WITHOUT UNFEATHERING ACCUMULATORS:
•
CAUTION: Numerous air starts without unfeathering accumulators can shorten engine-mount life.
1. Fuel Selector - ON
2. Throttle - SET approximately 1/4 travel
3. Aux Fuel Pump - ON
4. Magneto/Start Switch - BOTH
5. Mixture - FULL RICH
6. Propeller Control - MOVE FORWARD OF FEATHERING DETENT TO MIDRANGE
7. Magneto/Start Switch - START and PUSH TO PRIME (hold on START until windmilling begins and continue to prime as required)
•
NOTE: If air start is unsuccessful, return propeller control to the FEATHER position and secure engine.
8. When Engine Starts - ADJUST THROTTLE, PROPELLER, AND MIXTURE CONTROLS
9. Aux Fuel Pump - OFF (when reliable power has been regained)
10. Alternator Switch - ON
11. Oil Pressure and Oil Temperature - CHECK
12. Warm Up Engine (approximately 2000 rpm and 15 in. Hg)
13. Set power as required and trim.
