A. Do the operational test to read the class III faults of the BMC (Ref. AMM TASK 36-11-00-710-002)
(1)
If the operational test gives the maintenance message:
DRIFT REG-PRESS XDCR 8HA2
-replace the XDCR-BLEED REGULATED PRESS, ENG 2 (8HA2) (Ref. AMM TASK 36-11-16-000-001) and (Ref. AMM TASK 36-11-16-400-001).
(2)
If the operational test gives the maintenance message:
DRIFT TRANSF-PRESS XDCR 7HA2
-replace the XDCR-BLEED TRANSFER PRESS, ENG 2 (7HA2) (Ref. AMM TASK 36-11-15-000-001) and (Ref. AMM TASK 36-11-15-400-001).
