A. If the test gives a maintenance message:
Subtask 36-11-00-810-152-C ** ON A/C NOT FOR ALL - Do the trouble shooting procedure related to the maintenance message.
- replace the VALVE-BLEED PRESS REG [4001HA] AMM 36-11-52-000-040 and AMM 36-11-52-400-040.
- replace the SOLENOID-BLEED PRESS REG V CTL, ENG 1 [10HA1] AMM 36-11-55-000-001 and AMM 36-11-55-400-001.
- replace the XDCR-BLEED TRANSFER PRESS, ENG 1 [7HA1] AMM 36-11-15-000-001 and AMM 36-11-15-400-001.
- do a check and repair the wiring :
. from the FULLY CLOSED signal of the BMC1 (1HA1) to the bleed pressure-regulator valve (4001HA)
. from pin A/3 of the bleed pressure-regulator valve (4001HA) to the first terminal block ASM 361101.
A. If the test gives a maintenance message:
Subtask 36-11-00-710-251-A ** ON A/C NOT FOR ALL - Do the trouble shooting procedure related to the maintenance message.
- Replace the VALVE-BLEED PRESS REG [4001HA] AMM 36-11-52-000-042 and AMM 36-11-52-400-042.
- Replace the SOLENOID-BLEED PRESS REG V CTL, ENG 1 [10HA1] AMM 36-11-55-000-001 and AMM 36-11-55-400-001.
- Replace the XDCR-BLEED TRANSFER PRESS, ENG 1 [7HA1] AMM 36-11-15-000-001 and AMM 36-11-15-400-001.
- Do a check and repair the wiring :
. From pin AA/2B of the BMC1 (1HA1) to pin A/5 of the bleed pressure-regulator valve (4001HA)
. From pin A/3 of the bleed pressure-regulator valve (4001HA) to the first terminal block ASM 361101.
B. After the subsequent flight, make sure that the fault does not continue.
