Q

FADEC SYSTEM FAILURES 3 LEVELS

A

LEVEL 1 - FLASHING YELLOW GOV LIGHT

Flashing at idle or during starting or shut down: Governor redundancy failure, no impact on governing
function.
. Start-up procedure: abort, report to Maintenance Manual
. Autorotation training: cancel training, return to base.

LEVEL 2 - SOLID YELLOW GOV LIGHT

Permanently lighted :
Governing function degraded.
1. Collective - AVOID abrupt power changes.
2. IAS - MAINTAIN below VNE power off
LAND AS SOON AS PRACTICABLE
On ground : do not start the engine.

LEVEL 3 - RED GOV LIGHT (Total FADEC failure, metering valve frozen. EBCAU has taken over

IN FLIGHT:
1. Flight parameters - CHECK
Emergency mode automatically self-engages. GOV (yellow) illuminates.

2. Collective pitch…………….. AVOID abrupt changes

Maintain Ng > 80% Hp < 20000 ft
Maintain Ng > 85% Hp ≥ 20000 ft

LAND AS SOON AS PRACTICABLE
Approach and Landing : Make a powered approach. Avoid steep angle.

After touch down, shut-down :
Collective pitch - SLOWLY down to low pitch
Starting selector - OFF

NOTE

This failure can also results in loss of ΔNg and torque parameters on the VEMD.

• DURING ENGINE STARTING :
Starting selector - OFF position immediately
