counteract the yaw and roll from asymmetrical
thrust. The control forces, particularly on the
rudder, may be high. The pitch attitude for VYSE
will have to be lowered from that of VY.

If Engine Failure Occurs at
or Before Lift-off, Abort the
Takeoff.
If Failure of Engine Occurs After Lift-off:
1. Maintain Directional Control
2. Close Both Throttles

At least 5° of bank should be used, if necessary,
to stop the yaw and maintain directional control.
This initial bank input is held only momentarily,
just long enough to establish or ensure directional
control. Climb performance suffers when
bank angles exceed approximately 2 or 3°, but
obtaining and maintaining VYSE and directional
control are paramount. Trim should be adjusted
to lower the control forces.
• CONFIGURATION—The memory items from
the “engine failure after takeoff” checklist
[Figure 12-14] should be promptly executed to
configure the airplane for climb. The specific
procedures to follow will be found in the
AFM/POH and checklist for the particular airplane.
Most will direct the pilot to assume VYSE,
set takeoff power, retract the flaps and landing
gear, identify, verify, and feather the failed
engine. (On some airplanes, the landing gear is
to be retracted before the flaps.)
The “identify” step is for the pilot to initially
identify the failed engine. Confirmation on the
engine gauges may or may not be possible,
depending upon the failure mode. Identification
should be primarily through the control inputs
required to maintain straight flight, not the
engine gauges. The “verify” step directs the pilot
to retard the throttle of the engine thought to have
failed. No change in performance when the suspected
throttle is retarded is verification that the
correct engine has been identified as failed. The
corresponding propeller control should be
brought fully aft to feather the engine.
• CLIMB—As soon as directional control is established
and the airplane configured for climb, the
bank angle should be reduced to that producing
best climb performance. Without specific
guidance for zero sideslip, a bank of 2° and
one-third to one-half ball deflection on the
slip/skid indicator is suggested. VYSE is maintained
with pitch control. As turning flight
reduces climb performance, climb should be
made straight ahead, or with shallow turns to
avoid obstacles, to an altitude of at least 400
feet AGL before attempting a return to
the airport.
