Our line Maint guys have got a interesting snag with GPWS, They say that Ops test D1-34-45-00-710-801-A01-001 is okay, but If they do the functional Test D1-34-45-00-720-A01-001 It does not work, but system status is OK and they are unable to see or access Fault history.
They say if they change the GPWC and do the tests all is fine until they dispatcch the aircraft and it comes back from its flight with the same fault as before.....
So far they've continuety checked wiring, Swapped out MADC's, IAC's, PSEU, and GPWC all at differing times to see if one unit is causing this, until now still no result.....By the way all swapped parts working normally on other aircraft...
Any ideas anyone?
