I know the parts issue has been beaten to death..PMA,tso ect.
But, I need a battery relay.In the piper parts catalog they list the
piper number. In parenthesis, they list the manufacturers number. In
this case a 6041H105 relay. This relay is not even built to a MIL
spec,never mind a PMA.I think it was built for tractors.... But ,If I
purchase it through
Eaton or their distributor, I can get it at half price 150.00 ,(with an
eaton Certificate of Conformance) compared to pipers price of 300.00.I
am Legal in the eyes of the FAA?

If it's truly the identical part, with the identical part number, and your
A&P installs it (and signs your log), you're gold.

I'd buy the part, hand it to my A&P, let him check the part number against
the Piper microfiche, and leave it at that.
