craft weight, altitude at time of engine failure, and
single-engine performance must be considered in
deciding whether it is safer to land or continue flight.
c. Engine Malfunction Before Liftoff (Abort). If an
engine fails and the aircraft has not accelerated to
recommended liftoff speed (V 1of), retard power levers
immediately to IDLE and stop the aircraft with brakes
and reverse thrust. Perform the following:
1. Power levers - IDLE.
2. Braking - As required.
NOTE
If able to land on remaining runway, check
gear down and use brakes and reverse
thrust as required. If insufficient runway
remains for stopping, perform the following:
3. Condition levers - FUEL CUTOFF.
4. Fire pull handles - Pull.
5. Master switch - OFF.
d. Engine Malfunction After Liftoff. If an engine
fails after becoming airborne, maintain single-engine
best rate-of-climb speed (V yse) or, if air speed is below
V yse maintain whatever airspeed is attained between
liftoff (V 1of) and V yse until sufficient altitude is attained
to trade altitude for-airspeed and accelerate to V yse.

3.
(1.) Engine Malfunction after liftoff (abort),
perform the following and land in a
wingslevel attitude:
Power levers - Reduce.
Gear - DN.
Complete normal landing.
NOTE
If able to land on remaining runway, check
gear down and use brakes and reverse
thrust as required. If insufficient runway
remains for stopping, perform the following:
4. Condition levers - FUEL CUTOFF
5. Fire pull handles - Pull.
6. Master switch - OFF.
(2.) Engine malfunction after liftoff (flight
continued) perform the following:
TM 55-1510-221-10
1. Power - Maximum controllable.
NOTE
If airspeed is below V yse maintain whatever
airspeed has been attained (between V 1of and
V yse) until sufficient altitude can be obtained
to trade off altitude for airspeed to assist in
acceleration to V yse.
2. Gear - UP
3. Flaps - UP.
4. Landing lights - OFF.
5. Brake deice - OFF.
6. Engine cleanup - Perform.
7. Generator load - 100% max.
NOTE
Holding three to five degrees bank (one-half
ball width) towards the operating engine will
assist in maintaining directional control and
improve aircraft performance.
e. Engine Malfunction During Flight. If an engine
malfunctions during cruise flight, maintain control of the
aircraft while maintaining heading or turn as required.
Add power as required to keep airspeed from decaying
excessively and to maintain altitude. Identify the failed
engine by feel (if holding rudder pressure to keep the
aircraft from yawing; the rudder being pressed indicates
the good engine) and engine instruments, then confirm
identification by retarding the power lever of the
suspected failed engine. Refer to Chapter 7 for
single-engine cruise information. If one engine
malfunctions during flight, perform the following:
1. Autopilot/yaw damp - DISENGAGE.
2. Power - As required.
3. Dead engine - Identified.
4. Power lever (dead engine) - IDLE.
5. Propeller lever (dead engine) - FEATHER.
6. Propeller synchronization switch - Off.
7. Gear - As required.
8. Flaps - As required.
9. Generator load - 100% max.
10. Power - Set for single engine cruise.
