A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message: NO ACCELERATION FCU (8022KM) / APU FUEL SUPPLY / STARTER MOTOR 8KA associated with Fault Code Number (FCN) 215 (1) do a check for a blockage of the APU inlet. - If the fault continues: - check the APU accumulated hours TSN/TSO (Ref. AMM TASK 31-36-00740-006). (a) If the accumulated hours TSN/TSO are greater than 2000 hours: - make sure that the APU rotates freely. _ 1 If the APU rotates freely: - get acces to the APU DMM report (Ref. AMM TASK 49-00-00-970001) - compare the value of CT5ATP (corrected EGT during MES) from the DMM pade versus 663 deg.C (1225 deg.F). _ a _ b _ 2 If EGTA exceeds 663 deg.C (1225 deg.F) then continue in para. 2_ . If EGTA does not exceed 663 deg.C (1225 deg.F) then continue in para (b).
Get acces to the APU DMM report (Ref. AMM TASK 49-00-00-970001) - compare the START_TIME (time of last APU start) from the DMM page versus 60 seconds. _ a _ b If START_TIME exceeds 60 seconds (slow start time) then continue in para. 3_ . If START_TIME does not exceed 60 seconds then continue in para (b).

Get acces to the APU SHUTDOWN report 14 (Ref. AMM TASK 31-3600-740-011): - scan down and ensure that IGV position is within the normal range for APU start (10 - 22 degrees). _ a If IGV position is not in the normal range: - do a check for damage of the IGV actuator linkage and IGV assy (Ref. TASK 49-00-81-810-811).
