As you may or may not know, Piper changed their wheel pants (at least on the
Warrior) around 1978. IMHO the later model pants are quite a bit
nicer/better than the old ones. Now the question is, I own a '75 Warrior.
Can I legally put the later model pants on it?

If they weigh the same and Piper did not change the type certificate, you can put
the new ones right on. If they don't weigh the same and the type certificate did
not change, you need a logbook entry and new W&B. If the type certificate changed
(which I doubt), then you need an STC. All this assumes they will fit - if you
need to change the backing plate or make other mods to get them to fit, best
converse with your local FSDO.


Coincindentally, I just asked my mechanic about this recently. I was
looking at a pair of later model wheel pants on Ebay, and wondered the
same thing. He said that the later model wheel pants mount differently
(different backing plates), and that you couldn't do it with just a
logbook entry. You'd need a 337 and field approval.
