How do you determine if there is an inoperative engine
Dead foot- dead engine rudder pressure required to maintain directional control will be on the side of the operative engine
Throttle
partially retard the throttle for the engine that is believed to be inoperative, there should be no change in control pressure or in the sound of the engine if the correct throttle has been selected
low altitude and airspeed. this check must be done with extreme caution
One engine inoperative procedure
Engine failure during ground roll
- Throttle - idle
- Braking -maximum
- fuel selectors-off
- battery, alternator and magneto start switches - off
Engine failure after lift off and in flight
Immediate landing : higher take off weights will result in a loss of altitude while retracting the landing gear and feathering the prop
continues flight requires immediate pilot response
1. landing gear - UP
2. throttle to (inoperative engine) IDLE
3.propeller (inoperative) -FEATHER
4.Power (operative engine)-as required
4. airspeed - at or above the 50ft take off speed (80kts)
After positive control of the airplane is establishes
6. secure inoperative engine
a. mixture control - idle cut off
b. fuel selector - off
c.aux fuel pump-off
d. magneto/start switch - off
e.alternator switch - off
f. cowl flap - close
7.airspeed -85kts
8.electrical load - monitor (maximum load of 100% on remaining engine)
Most important is to maintain directional and lateral control.
if airspeed is below 65 kts reduce power on operative engine a required to maintain control

AIR START emergency procedure
- pilot should determine the reason for engine failure before attempting an air start
with unfeathering accumulators - fuel selector - on
- throttle - set approx 1/4 travel
- Aux fuel pump - on
- magneto/ start switch -both
- Propeller control - move full forward until engine windmills, then back to midrange use starter momentarily if airspeed is below 100kts
-if propeller prop 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 - Engine starts - adjust throttle propeller and mixture controls
- AUX FUEL PUMP - off (when reliable power has been regained).
10 Alternator switch - on - oil pressure and oil temp - check
- warm up engine (approximately 2000 rpm and 15 in HG)
- set power as required and trim
Engine fire (ground)
- Mixture controls - idle cut off
- Continue to crank affected engine
- Fuel selectors- off
- Battery and alternator switches- off
- Extinguish fire with extinguisher
