Would you please tell me what regulation specifes the use of Tefzel wiring in gliders...


Valid comment. I shouldn't be so blith with my use of the "FAA" word.

Let me rephrase. Every book I have ever read about aviation wiring,
and every aviation tech I have ever worked with, and every A&P who has
every looked over my shoulder and signed my log book, has always
required Tefzel (ETFE).

Now, if that isn't an implicite FAA requirement, I don't know what
is. However, there must be something in the regs that is driving all
this. While there probably isn't a reg that says "you must use ETFE",
is there one that says something about wiring being; Abrasion
resistant? Burn resistant? Doesn't release toxins? Doesn't fray?
If there isn't an FAA reg on this, I can start going back to Radio
Shack. ;-) Only kidding...really.

However, when I council a newbie about why his wiring is just plain
wrong, why he shouldn't use spade lugs, and why fuses at batteries (!)
are a necessary thing, etc, etc, I often blithly spead the "FAA" word
around to put the fear of God in them. I will probably continue that
habit. And I don't care if it is standard certified or experimental,
my (high) standards are all the same. It keeps life simpler that way.

My $0.02.
