A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
OVERTEMPERATURE
CHECK IGV ASSEMBLY/IGV ACTUATOR (8014KM)
associated with Fault Code Number (FCN) 83
- do a check for damage/leakage of the fuel supply and return lines of the IGV ACTUATOR (P21).
(1) If there is damage/leakage in the fuel supply and return lines:
- do a repair
(2) If the fuel supply and return lines are OK:
- do a check for damage of the IGV ACTUATOR linkage and the IGV assembly.
(a) If the IGV ACTUATOR linkage/IGV assembly are OK:
- do a check for damage/contamination of the electical connector P21 of the IGV ACTUATOR (8014KM)
1 If the electrical connector P21 is damaged/contaminated:
_
- do a repair/cleaning. 2 If the electrical connector P21 is OK:
_
- use a multimeter to do the resistance check across pin 4 and pin 10 of the IGV ACTUATOR (P21).
a If the resistance value is < 100 kOhms:
_
- replace the IGV ACTUATOR (8014KM) (Ref. AMM TASK 49-23-51-000-004) and (Ref. AMM TASK 49-23-51-400-004).
