Engine-Failure during Flight
An engine-failure is possible in all flight-phases and must be considered in flight-
planning. Existing experience with the engine shows, that certain engine-failure-
situations are more likely than others. The relevant emergency procedures are
described in the following section.
Engine-failure due to carburator-icing was not observed, because the
carburator-air is heated by the turbocharger.
In the case of a total electrical failure, the engine does not stop. The ignition-
circuit is separated from the electrical-system (for example, if the engine-master-
switch at the panel fails).
In most cases the propeller windmills in the airstream. In this case the engine-
starter does not need to be operated to restart the engine.
After engine-failure in flight, the following restart-procedure is recommended:
1.
Air-speed
55 kts - 75 kts /
100 km/h - 140 km/h
2.
Fuel-shut-off-valve
OPEN
3.

4.
Master Switch (battery)
CHECK if ON
5.
Engine Master Switch
CHECK if ON
6.

installed)

For restart, the propeller must
NOT be in the FEATHER
position.
