Failure of the Two Engines

---

1. Possible Causes
· snow ingestion
· Water projections to the radio altimeter antenna
· significant presence of water or presence of snow on the runway

A. Test
(1) Not applicable, the confirmation can cause damage to the engine.
4. Fault Isolation

A. There is no known engine related problem that would cause the ECAM warning ENG DUAL FAILURE to
come into view.
NOTE: Do the trouble shooting of individual engine per TSM procedure for ENG 1(2) FAIL ECAM warning:
- for engine 1 (Ref. TSM 73-00-00-810-855) ,
- for engine 2 (Ref. TSM 73-00-00-810-856) .
(1) No trouble shooting is required if the fault has occured on wet or snow-covered runway:
(a) During use of the thrust reverser at low speed on snow-covered runway.
The engine failure was most likely caused by snow ingestion .
· Make sure that the air intake and fan blades are free from ice or snow accumulation before the
next flight.
(b) During taxiing on snow-covered runway.
The reversion of the radio-altitude to NCD (non-computed data) can occur and cause the
removal of the inhibition of the reported ECAM warnings by the Flight Warning Computer. Refer
to TFU 34-42-00-013.
(c) During taxiing (or when the aircraft is stopped) on a wet or snow-covered runway.
These conditions can cause disturbance of the radio altimeter signal:
· Water projections to the radio altimeter antenna by main landing gears
· Reflections of emitted signals due to significant presence of water or presence of snow on the
runway .
Refer to TFU 34-42-00-003.
(2) If the failure occurred in any other conditions, do the trouble shooting of the fuel system supply and
do a check of fuel samples for quality or presence of water.

B. No additional maintenance action is required if the fault is not confirmed.
(1) Repeat the fault isolation procedure if the fault continues. [Rev.6 from Feb 2017] 2026.04.04 04:36:08 UTC
