A. If the fault symptom is identified by the crew observation: Engine 2 low power and high EGT:
· Do the inspection of the VSV mechanism Ref. AMM 75-32-42-200-010 .
(1) If the fault continues:
· Do the functional check of the bleed valve operation on engine 2 Ref. AMM 75-32-52-700-011 and
Ref. AMM 75-32-54-700-011 .
NOTE: For additional information on bleed valve effects on engine operation, refer to (Ref. 75-00-00
Page Block 301 Task Supporting Data) and (Ref. TSM 75-00-00-810-804) .
(2) If the fault continues:
· Do the functional check of the solenoid valve on engine 2 Ref. AMM 75-32-51-700-010 and Ref.
AMM 75-32-53-700-010 .
(3) If the fault continues:
· Do the inspection of the HP compressor Ref. AMM 72-00-00-200-016 .
(4) If the fault continues:
· Do the visual inspection of the air offtakes for signs of important leakage on engine 2.
(5) If the fault continues:
· Examine the HPC stage 10 piston ring.
(6) If the fault continues:
· Do a cleaning of the LP compressor Ref. AMM 72-31-11-100-010 . [Rev.6 from Feb 2017] 2026.04.04 04:36:08 UTC
