- Replace the 3 Fuel nozzles position 3,5 and 7 (Ref. AMM TASK 73-11-40-000-002) and (Ref. AMM TASK 73-11-40-400-002).
NOTE : Fuel nozzles position 3,5 and 7 are the most exposed to
____ contamination in case of fuel manifold coking.
(10) If the fault does not continue during subsequent flights:
NOTE : If the EGT exceedence is determined to be caused by fuel
____ manifold coking, then replacement of all other fuel nozzles as well as replacement of the fuel manifolds is required.
- replace all Fuel nozzles except position 3,5 and 7 (replaced in previous step) (Ref. AMM TASK 73-11-40-000-002) and (Ref. AMM TASK 73-11-40-400-002).

A. If the fault symptom is identified by the crew observation: ENG1-N1/N2 mismatch on the same engine:
(1) Do an operational test of the FADEC on the ground (with engine motoring) to do a check of the VSV/VBV position (Ref. AMM TASK 73-29-00-710-040).
(2) Do a visual inspection of the variable bleed valve system to do a check of the VBV doors position (Ref. AMM TASK 75-31-00-210-002).
