A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
REVERSE FLOW
SURGE CONTROL VALVE (8058KM)
associated with Fault Code Numbers (FCN) 87
- do a check of damage/leakage of the fuel supply and return lines of the SURGE CONTROL VALVE (8058KM)
(1) If there is damaged/leaking in the fuel supply and return lines:
- do a repair.
(2) If the fuel supply and return lines are OK:
- replace the SURGE CONTROL VALVE (8058KM) (Ref. AMM TASK 49-51-52-000-003) and (Ref. AMM TASK 49-51-52-400-003).
(a) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).

__________________
A. Read-out of ECB Trouble-Shooting Data
(1) Put the APU MASTER SW to the ON position.
(2) Get access to the APU SHUTDOWN report.
(3) Push the '>' adjacent to LRU DATA:
- the MCDU menu shows
OIL FILTER SHOWS CLOGGED
(4) Start the APU and apply Bleed Air for 20 seconds, minimum (Ref. AMM TASK 49-00-00-860-008).

A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
CLOGGED OIL FILTER
LUBE PUMP FILTER P9 + GEN SCAV FILTER P5
associated with Fault Code Numbers (FCN) 102
- If the TSM steps below do not clear the fault, do the TSM task (Ref. TASK 49-90-00-810-812).
- do a check for contamination of the MAGNETIC-DRAIN PLUG (Ref. AMM TASK 49-91-42-200-004).
- do a check for contamination of the GEN SCAV OIL FILTER (P5) and LUBE PUMP OIL FILTER (P9):
- remove the GEN SCAV OIL FILTER (P5) and LUBE PUMP OIL FILTER (P9) and do a check of the removed oil filter elements (Ref. AMM TASK 49-91-41-200-002).
(1) If the oil filter element(s) is/are contaminated with: . copper wire particles, . nonmetallic flakes, . phenolic resin.
- remove the APU GENERATOR (8XS) (Ref. AMM TASK 24-23-51-000-001).
