Subject
- This AD results from the possibility of loss of automatic activation of the engine inlet ice protection system when flying in ice condition. Even thought the failure is announced by the caution
messages “A-I Eng 1 Fail” e “A-I Eng 2 Fail”, if the engines inlet ice protection system is not manually activated, ice may accrete in the engine inlet and causes engine to shut down.
Also there is the possibility of right hand (RH) engine compressor to stall after the Auxiliary Power Unit (APU) becomes the active bleed source for the left side, following left hand (LH)
engine failure, under a condition where both engines are close to idle, the APU is running, and the APU bleed button is pushed in (automatic position).
Since these conditions may occur in other airplanes of the same type and affect flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this AD
in the indicated time limit.
