**ON A/C 001-003, 051-062,
A. Check/Test
(1) Do a check on the APU Shutdowns report if a
NO FLAME - LOW FUEL PRESSURE CHECK APU FUEL SUPPLY autoshutdown or a NO ACCELERATION - LOW FUEL PRESSURE CHECK APU FUEL SUPPLY autoshutdown
has occured BEFORE the
IGV FAILURE - INLET GUIDE VANE ACTR P21 autoshutdown.
(2) Purge the APU fuel feed-line (Ref. AMM TASK 28-22-00-710-001).
(a) If you find Air-in-Fuel then purge the fuel line from the Fuel Control Unit to the IGV-Actuator (Ref. AMM TASK 49-32-11-000-001) and (Ref. AMM TASK 49-32-11-400-001).
(3) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-004). NOTE : During the operational test of the APU, examine carefully the
____ fuel lines from the fuel control unit to the inlet guide-vane actuator:
- fuel leaks are not permitted, correct/replace as necessary. R **ON A/C 063-099, 401-499,
