Re: Part 43 Appendix D

'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.'

'Carl...
Great Idea!!
If we could gather and compile all the "gotchas" we could put them into a
book. The Eastern Cessna 195 Club has such a book..."The Shadetree Mechanic"
which is worth its weight in platinum to 195 owners.
That could also be on a CD...
This forum...thanks to Jamie Treat...is already a goldmine of information.

'This is what I had in mind. We have Part 43; what I want to know is
where the hot spots are on a 24 series, and any special tips or
techniques for inspecting. Likewise for Ranger and Warner engines.

For instance, I've read that the landing gear on a 24 deserves special
attention (I'll dig out the newsletters and post what I can find on
them).

If folks will contribute tips, I'll collate them into a single document.

'Everyone that flies a F24 needs to inspect the vertical fin. They tend to crack vertically in the middle of the spar. Remove the gap seal standoffs and check under them. We have found 5 that are cracked! Including the one that broke on me inflight and almost ruined my day!!!!!!!!!!!!

If your airplane is covered, grab the top of the vertical fin. Push and pull rather vigorously! If the fin moves, take it off and uncover the vertical spar and check it.. They will usually move in the area of the vertical and the horizontal spar joint. This is at the top of the vertical tail post part of the fuselage.

I am taking cover from tornadoes now so I will sing off!

'If your 145 Warner is of the tapershaft type, you may want to check the
depth of the hole in the crank shaft. Measure from the front thru the
prop as far as you can into the shaft. If the distance is 4 3/8" deep
you are ok. If the distance is 10 5/16 " the following may apply:

Warner service letter A-11, 9/14/42
Warner service letter A-18, 2/22/46'
