Part 43 Appendix D
Posted: Sat May 05, 2001 7:19 pm
'You know, some of you Fairchild owners know an awful lot about your aircraft.
Part 43 paints the inspection process with a broad brush. It is perfectly
legal to create your own checklist specific to your aircraft using the
Appendix D's scope and detail as an outline. You all could knock heads and
come up with a comprehensive check list naming problem areas, how and where
to use a borescope, what places need NDT, how to check spars, cylinder leak
downs, whatever. You would make present and future F-24 owners happy as well
as the administrator.
Concerning the magnetized crankshafts, I had the opportunity to speak to a
few professors at the College of Aeronautics at LaGuardia Airport. Here is
what they said. #1 "Take the damn think out and replace it with an APU."
That's auxiliary power unit, A small jet A turbine coupled to an alternator.
#2 An NDT professor, "Well, people get PHD's to solve problems like that."
#3 "Why don't they just put the generator back on?" And that's what the
professors of A&P technology have to say on the subject. But I have my own
thoughts. I assume that these engines don't have any filtration save for
maybe a screen. Has anyone tried putting a strong magnet in the oil sump? How
about a lead shield around the alternator? To change the alt. output voltage
the voltage reg. changes the voltage to the rotating field coil. A high load
or a faulty reg. could cause the magnetic field to grow quite large. No? Has
anyone checked the ATP Navigator for F-24 alerts? TTFN Carl.'
