IGV FAILURE - INLET GUIDE VANE ACTR P21:
- remove the INLET GUIDE VANE ACTUATOR P21 (Ref. AMM TASK 49-23-51-000-002) and do a push/pull test on the IGVs to check the IGV movement: . make sure that the IGV has a travel range of 1 in. (25.4 mm), . measure the force of the IGV movement.
(1) If a force less than 30lbf (13.34daN) is necessary to move the IGVs and the travel range is OK:
- replace the INLET GUIDE-VANE ACTUATOR P21 (Ref. AMM TASK 49-23-51-000-002) and (Ref. AMM TASK 49-23-51-400-002).
(a) If the fault continues:
- replace the FUEL CONTROL UNIT P19 (Ref. AMM TASK 49-32-11-000-001) and (Ref. AMM TASK 49-32-11-400-001).
(b) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/G8, G9, E8, E9, E11, E12 to the INLET GUIDE-VANE ACTUATOR P21/1, 2, 5, 6, 3, 4 (Ref. ASM 49-61/02).
(c) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).
(2) If a force more than 30lbf (13.34daN) is necessary to move the IGVs or the travel range is NOT OK:
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-400-001).
