A. Maintenance Action
(1) If the APU Last Leg Report gives the maintenance message:
BLD FLOW XDCR (8039KM):
Fault Code Number: 000 or 001
- replace the COMPRESSOR DISCHARGE-PRESSURE SENSOR (8039KM) (Ref. AMM TASK 49-51-19-000-002) and (Ref. AMM TASK 49-51-19-400-002).
(a) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/A1, A4, B2, B3, A2, A3 to the COMPRESSOR DISCHARGE-PRESSURE SENSOR P24/1, 2, 3, 4, 5, 6 (Ref. ASM 49-61/02).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002).
(2) If the APU Last Leg Report gives the maintenance message:
BLD FLOW XDCR (8039KM):
Fault Code Number: 003 or 103 or 149
- do a check and repair the wiring between the Delta P Sensor (P24) and the ECB (59KD) (Ref. ASM 49-61/02).
(a) replace the COMPRESSOR DISCHARGE-PRESSURE SENSOR (8039KM) (Ref. AMM TASK 49-51-19-000-002) and (Ref. AMM TASK 49-51-19-400-002).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002).
(3) If the APU Last Leg Report gives the maintenance message:
BLD FLOW XDCR (8039KM):
Fault Code Number: 170
- replace the COMPRESSOR DISCHARGE-PRESSURE SENSOR (8039KM) (Ref. AMM TASK 49-51-19-000-002) and (Ref. AMM TASK 49-51-19-400-002).
(a) do a check and repair the wiring between the Delta P Sensor (P24) and the ECB (59KD) (Ref. ASM 49-61/02).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002).
(4) If the APU Last Leg Report gives the maintenance message:
BLD FLOW XDCR (8039KM):
Fault Code Number: 171
- replace the COMPRESSOR DISCHARGE-PRESSURE SENSOR (8039KM) (Ref. AMM TASK 49-51-19-000-002) and (Ref. AMM TASK 49-51-19-400-002).
(a) do a check and repair the wiring between the Delta P Sensor (P24) and the ECB (59KD) (Ref. ASM 49-61/02).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002).
B. Do the test given in para. 3.
