3. Fault Confirmation__________________
R A. Test
R CAUTION : IF THE ENGINE WAS NOT RESTARTED AFTER THE EVENT OR WITHIN 24
_______ R HRS, DO THE ENGINE DRY OUT PROCEDURE, OR FURTHER DAMAGE TO R ENGINE MAY OCCUR.
R (1) If the engine was successfully restarted after the event:
R - do the operational test of the FADEC 1A and 1B (with the engine non
R motoring) (Ref. AMM TASK 73-29-00-710-040).
R (2) If the engine could not restart after the event or no start attempt
R was done:
R - not applicable. No test must be attempted.
4. Fault Isolation
_______________
A. This ECAM warning is shown if the engine is running below minimum idle and N2 is less than 50% with the Master Lever set to ON.
CAUTION : WHEN THE "ENG/MASTER" LEVER IS IN THE "ON" POSITION, BE VERY
_______ CAREFUL NOT TO SET THE "ENG/MODE" SELECTOR SWITCH TO "CRANK" OR "IGN/START". IF YOU DO SET THE SELECTOR SWITCH TO ONE OF THESE POSITIONS, THE ENGINE WILL START. THERE IS THUS A RISK OF INJURY TO PERSONS AND OF DAMAGE TO EQUIPMENT.
- Do the trouble shooting related to the failure message(s) triggered (if any) during the fault confirmation test referred to in Para. 3.A.
- Do a check of the Post Flight Report (PFR), of the FADEC Last Leg Report and SMR/Class 3 Report for ECU, HMU, ALT, FMV, VSV, PS3 failure messages.
(1) If any failure message is shown:
- do the trouble shooting related to the failure message(s).
(2) If the fault occurred just after the engine start sequence or during taxi out or at first engine acceleration:
- do a check of correct operation of the low pressure fuel shut-off valve (Ref. AMM TASK 28-24-00-720-001),
- check that the drive mechanism of the valve is not broken.

(3) If no failure message is found, or if at the time of the event, the crew reported symptoms such as stall, high EGT, sudden power loss, high vibration:
- make sure the fan rotates freely and smoothly,
- do a visual inspection of the LPT stage 4 rotor blades, R - do a check of the Master Magnetic Chip Detector for particles (Ref. R AMM TASK 79-00-00-281-002),
