Interior Upgrade Question

My experience is with large transport category Part 25 aircraft and
the burn test requirements are much more severe than Part 23. Read
25.853 sometime.

I have, and it reads exactly the same as 23.853. That should give you
a clue - 23.853 aqpplies ONLY to commuter category aircraft certified
under 14CFR23. Not normal, utility, or aerobatic aircraft. The
standards for those aircraft (as well as those certified under CAR 3)
are much less stringent. Years ago, when AC 43-13 was mistakenly
printed with a paragraph requiring burn tests for all Part 23
aircraft, Rod Farlee (who used to be a regular here) sent a letter to
O'Brien himself, and got a reply stating this - and also stating that
AC 43-13 was wrong and would be corrected. And so it was. I'll be
happy to send a copy of this letter to anyone here.

In other words - everything you said is totally inapplicable to small
aircraft not operated under Part 135. It was nothing but FUD - Fear,
Uncertainty, Doubt.

I am an A&P with IA and haven't done an annual in over thirty years.

Good. We don't need people trying to apply regulations written for
large commercial aircraft to small private aircraft.
