A. If the test gives the maintenance message:
CHECK BMC2
Subtask 36-11-00-810-163-B ** ON A/C NOT FOR ALL CHECK BMC2
- replace the BMC-2 [1HA2] AMM 36-11-34-000-001 and AMM 36-11-34-400-001.
- replace the XDCR-BLEED TRANSFER PRESS, ENG 2 [7HA2] AMM 36-11-15-000-001 and AMM 36-11-15-400-001.
- replace the SENSOR-EXCHANGER OUT TEMP, ENG 2 [6HA2] AMM 36-11-17-000-001 and AMM 36-11-17-400-001.
- do a check for 28VDC at pins 1 and 2 of the bleed transferred pressure transducer (7HA2).
- do a check and repair the wiring ASM 361102 between pin 1 of the bleed transferred pressure transducer (7HA2) and the first terminal block.
- do a check and repair the wiring ASM 361102 between:
. pin 3 of the bleed transferred pressure transducer (7HA2) and pin AA/15B of the BMC2 (1HA2)
. pin 4 of the bleed transferred pressure transducer (7HA2) and pin AA/14B of the BMC2
. pin 4 of the exchanger out temperature sensor (6HA2) and pin AA/10B of the BMC2
. pin 2 of the exchanger out temperature sensor (6HA2) and pin AA/9B of the BMC2.
A. If the test gives the maintenance message:
CHECK BMC2 (1HA2)
Subtask 36-11-00-710-273-A ** ON A/C NOT FOR ALL CHECK BMC2 (1HA2)
- replace the BMC-2 [1HA2] AMM 36-11-34-000-001 and AMM 36-11-34-400-001.
- replace the XDCR-BLEED TRANSFER PRESS, ENG 2 [7HA2] AMM 36-11-15-000-001 and AMM 36-11-15-400-001.
- replace the SENSOR-EXCHANGER OUT TEMP, ENG 2 [6HA2] AMM 36-11-17-000-001 and AMM 36-11-17-400-001.
- do a check for 28VDC at pins 1 and 2 of the bleed transferred pressure transducer (7HA2).
- do a check and repair the wiring ASM 361102 between pin 1 of the bleed transferred pressure transducer (7HA2) and the first terminal block.
- do a check and repair the wiring ASM 361102 between:
. pin 3 of the bleed transferred pressure transducer (7HA2) and pin AA/15B of the BMC2 (1HA2)
. pin 4 of the bleed transferred pressure transducer (7HA2) and pin AA/14B of the BMC2
. pin 4 of the exchanger out temperature sensor (6HA2) and pin AA/10B of the BMC2
