A. If the fault symptom is identified by the crew observation: ENG1 - Blow out:
· replace the PUMP-HP/LP FUEL (2001EM1) Ref. AMM 73-12-41-000-010 and Ref.
AMM 73-12-41-400-010 .
(1) If the fault continues:
· replace the FMU ( 4000KC ) Ref. AMM 73-22-52-000-010 and Ref. AMM 73-22-52-400-010 .
(2) If the fault continues:
· replace the EEC ( 4000KS ) Ref. AMM 73-22-34-000-010 and Ref. AMM 73-22-34-400-010 .
(3) If the fault continues:
· do the inspection of the VSV mechanism Ref. AMM 75-32-42-200-010 .
(4) Do the functional check of the bleed valve operation on engine 1 Ref. AMM 75-32-52-700-010 and
Ref. AMM 75-32-54-700-010 .
