My Mooney is CAR3, so what does that mean?

As I think I mentioned earlier, it would be hard to buy any interior materials these days that do NOT meet the modern requirements.  You would be dumb to put something flammable or toxic in your plane.  Automotive and commercial aircraft interiors as well as newer Part 23 planes have to meet it.  It isn't a big deal IMO.  Just check what you buy, and maybe get a scrap and light it on fire to satisfy yourself.  Note exactly what was used in the logs.  Get an A&P or IA to update the W&B as required.

 

Another minor nit, even if you use good materials, our seats are NOT completely Part 23-compliant as they're not meeting the newer crashworthiness criteria in the modern regs.

Now, if there was a way to mix flame retardants into the fuel tanks after a hard landing.....

 

 

That is done on the macro level when building the tanks. Modern racecars have extra plastic on the outside of the tank, and a honeycomb structure on the inside. Seems to work for them . . . Don't see why the FAA would need more than $1 million or two and a three-year test plan per aircraft model to implement proven technology for us.
