_______________
**ON A/C 001-003, 051-062,
A. If an APU auto shutdown occurs and the APU SHUTDOWNS report gives the maintenance message:
REVERSE FLOW - DP XDCR P24 OR PT XDCR P23 OR SCV:
NOTE : If an APU auto shutdown occurs with the Bleed Ctl Valve closed (NO
____ BLEED Demand) then start with step (2) (LCIT P22 Replacement).
- replace the PNEUMAIC-SENSOR-ASSY
(Ref. AMM TASK 49-51-13-000-001)
(Ref. AMM TASK 49-51-13-400-001).
(1) If the fault continues:
- replace the SURGE CONTROL VALVE P18
(Ref. AMM TASK 49-51-52-000-002)
(Ref. AMM TASK 49-51-52-400-002).
