3.8.4
Drive-Section-Failure
In the case of a failure of the drive-section the power-transmission from the
engine to the propeller is destroyed. The cause could be a failure of the gear,
the drive-shaft, their adapters or couplings. This is indicated by the smell of fire
or noise from the power-transmission-system. The failure of the drive-section is
most critical in case of applied engine load. The engine can exceed the
maximum RPM or vibrations can cause structural damage.
After drive-section-failure, the following procedure is recommended:
1.
Throttle
immediately to IDLE
2.
Air-speed
~ 60kts / 110km/h
3.
Engine
OFF if essential
4.
Prepare for an off-field-landing or a landing on next suitable airfield.
3.8.5
Failure of Engine-Starter
If the engine-ignition-switch fails, the engine-starter will not work for an in-flight
engine-restart. A failure of the engine-ignition-switch may be the cause.
The following procedure is recommended:
1.
Master-circuit-breaker:
CHECK
2.
Engine-Bus-circuit-breaker:
CHECK
3.
Master-switch:
ON (Voltmeter must show
operating voltage >10V)
4.
Engine-master-switch:
ON
5.
Engine-instrumentation and control-
lights
CHECK
(especially YELLOW and RED
lights of the TCU during self-
check)
If a restart of the engine is not possible:
6.
Depending on altitude:
Engine-restart-procedure with windmilling propeller.
Or prepare for an engine-off-landing on next suitable airfield.
