NOTE : This fault symptom comes into view when there is a possible BMC 1
____ fault plus an overpressure or an overtemperature on the engine 1 bleed system.
-do the BITE test of the BMC 1 (Ref. AMM TASK 36-11-00-740-001).
(1) If the test is not OK:
-replace the BMC-1 (1HA1) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001)
-
do the trouble shooting procedure for an overpressure (Ref. TASK 36-11-00-810-807)
-
do the trouble shooting procedure for an overtemperature (Ref. TASK 36-11-00-810-803).
