A. If the APU GND SCANNING menu gives the maintenance message
LOW OIL LEVEL:
associated with the Fault Code Number (FCN) 245.
- do a visual check on the oil sight glass on the accessory drive gearbox and make sure that the oil level in the APU oil reservoir is sufficient.
(1) If the oil level is below the ADD mark:
NOTE : AI recommends to do an oil servicing at next daily maintenance
____ when a LOW OIL LEVEL message on ECAM APU page comes on. In case of no oil leakage, sufficient oil is available to allow further 10 hours of APU operation.
- do the oil servicing (Ref. AMM TASK 49-90-00-600-007).
- calculate the APU oil consumption.
(a) If the APU oil consumption is more than 93 cm3 (5.67 in.3) per APU operating hour:
- examine the APU for oil leaks on the oil system components or oil lines (Ref. AMM TASK 49-00-00-790-003).
1 If you find oil leaks:
_ - correct/replace as necessary.
a If the fault continues:
_
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-004) and (Ref. AMM TASK 49-11-11-400-004).
(2) If the oil level is above the ADD mark:
- replace the LOW OIL LEVEL SWITCH (8087KM) (Ref. AMM TASK 49-93-16-000-003) and (Ref. AMM TASK 49-93-16-400-003).
(a) If the fault continues:
- do a check and repair the aircraft wiring from the ECB (59KD) AB/H2 to the LOW OIL LEVEL SWITCH (8087KM) P8/2 and the LOW OIL LEVEL SWITCH (8087KM) P8/1 to GND (Ref. ASM 49-61/01).
(b) 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)
