3.5.4 UNFEATHERING & RESTARTING THE ENGINE IN FLIGHT
WARNING
Do not attempt to restart the feathered engine when the
reason of the engine failure cannot be identified since the
un-feathered propeller of an inoperative engine might not be
able to be feathered again.
WARNING
An unfeathered propeller causes increased drag and
reduces/increases climb/sink rate up to 200 ft/min.
If the reason of the engine failure can be identified as the result of an improper handling
by the pilot and there is no indication of malfunction or engine fire a restart may be
attempted. Refer to 3.5.2 - ENGINE TROUBLE SHOOTING to check for possible causes.
If TAE 125-01 engines are installed:
NOTE
Restarting the engine in flight is possible at altitudes below
6000 ft pressure altitude.
Above 6000 ft pressure altitude restart has not been
demonstrated.
