FADEC MALFUNCTION IN FLIGHT


Note:
a) One FADEC Light is flashing
1. Press FADEC test knob at least 2 seconds
2. FADEC light extinguished (LOW warning category):
a) Continue normal flight,
b) Inform service center after landing.
3. FADEC light illuminated steady (HIGH warning category)
a) Monitor the other FADEC light.
b) Land as soon as possible.
c) Select an airspeed to avoid engine overspeed.
d) Inform service center after landing.
The propeller will normally continue to turn
as long as the airspeed is above 65 KIAS.
Should the propeller stop at an airspeed of
more than 65 KIAS or more, the reason for
this should be found out before attempting
a restart.
If it is obvious that the engine or propeller is
blocked, do not use the Starter.
If the Engine Master is in position OFF, the
Load Display shows no value even if the
propeller is turning.
The FADEC consists of two components
that are independent of each other: FADEC
A and FADEC B. In case of malfunctions in
the active FADEC, it automatically switches
to the other.
