3.5.6 ENGINE FAILURES IN FLIGHT
(a) Engine Failure During Initial Climb at Airspeeds Below v
mCA
= 68 KIAS
WARNING
As the climb is a flight condition which is associated with high
power settings, airspeeds lower than v
mCA
= 68 KIAS should
be avoided as a sudden engine failure can lead to loss of
control. In this case it is very important to reduce the
asymmetry in thrust to regain directional control.
1. Rudder ............................. apply for directional control
2. Power levers ......................... retard as required to maintain
directional control
3. Airspeed ............................ v
YSE
= 82 KIAS /
above v
mCA
= 68 KIAS as required
4. Operative engine ...................... increase power as required if
directional control has been
re-established
Establish minimum / zero sideslip condition (approx. half ball towards good engine;
3° to 5° bank).
5. Inoperative engine ..................... Secure according to 3.5.3 -
ENGINE SECURING
(FEATHERING) PROCEDURE
Continue according to Section 3.5.9 - FLIGHT WITH ONE ENGINE INOPERATIVE and
land as soon as possible according to Section 3.5.7 - LANDING WITH ONE ENGINE
INOPERATIVE.
If the situation allows, you may climb to a safe altitude for troubleshooting (3.5.2 - ENGINE
TROUBLESHOOTING) in order to try to restore engine power.
