7.3.2 Both FADEC lights flashing
1. Press FADEC-Testbutton at least 2 seconds
(refer to Chapter 4, Section 4.4.3, Page 7 of this Manual)
2. FADEC lights extinguished (temporary failure):
a) Continue flight normally
b) Inform service center after landing. The lights will
illuminate after the ignition has been switched off and
on.
3. FADEC lights steady illuminated (steady failure or high
category failure):
a) Check the available engine power
b) Expect engine failure
c) Flight can be continued, however the pilot should
• select an airspeed according to the appropriate
POH
• fly to the next airfield or landing strip
• be prepared for an emergency landing
d) Inform service center after landing
7.3.3 Abnormal engine behavior
If abnormal engine behavior should occur during flight and the
FADEC does not automatically switch over to FADEC B, it is
possible to switch over to FADEC B manually using the "Force B"
switch. However, this switch position prevents the auto-
monitoring between the two FADEC halves.
Before attempting to restart the engine when on the ground,
check the plug and socket connections according to Chapter 6,
Annex 7, Page 18 of this Manual and carry out the “Pre-Flight
Check“ as described in Chapter 6, Section 6.1, Page 2 of this
Manual.
Note: The Load Display may not correspond to the current value.
WARNING: It is strongly recommended to always operate with the Force B
switch in the automatic position, as this will allow the FADEC
system to choose automatically the healthiest FADEC.
