Lately the FAA has been under pressure for lack of oversight and being too cozy with management. OK so the FAA got real picky about our MD 80 wiring bundle fiasco. As I remember the inspector(s) were anal about the spacing and the direction of the knots. Even as all practices and parts were airworthy we still grounded our fleet under pressure from the FAA. Now why is it that the FAA allows SouthWest to continue to fly their aircraft with know unairworthy parts until December? Is there one set of rules for AA and another for SWA? Seems to me that bogus parts should be a valid reason to ground the affective aircraft until replaced versus wire bundle lacing practices. Any comments on this logic????
