Hello,
Any suggestions? Typical heat of a skylight equipped airplane that may sit out for a few hours in the summer.

Second: supplier of said vinyl says it will cost $125 to get sample approved by FAA. Anyone have a lab they'd recommend to do same? it's typical flame resistant auto vinyl.

Anyone have a rec for an upholstery supplier? Airtex color selection not so much.
 
It's in the interior, wing root and just aft of skylight. FAR23 required, I b'lieve, just like seat upholstery, headliners, etc.

For a PA-20, being a CAR-3 certificated aircraft, you do not need a burn certificate. All you have to do is have flame-resistant material.
 
CAR-3: § 3.388 Fire precautions—(a) Cabin interiors. Only materials which are flashresistant shall be used. In compartments where smoking is to be permitted, the materials of the cabin lining, floors, upholstery, and furnishings shall be flame-resistant. Such compartments shall be equipped with an adequate number of selfcontained ash trays. All other compartments shall be placarded against smoking.

Got it. Find an auto shop source that cas the tag for flame resistance.
 
Would 3M 03614 work? It's a two sided ¾" adhesive tape that's used to bond plastic auto body panels to painted metal surfaces. A roll costs around $10 at O'Reilly or AutoZone.

There are other 3M bonding tapes and epoxies available. The 03614 has worked well on my projects.
 
Aerosol contact cement. Spray lightly to both surfaces, let dry, stick it on.

You do know that very little in aviation is more flammable than Ceconite and dope, right? Not to scare you, it just is what it is. Your curiosity about burn certs is misplaced. The best thing you can do to manage fire? Don't crash. If you do? Get the hell out of the airplane as fast as you can.
 
A lot of people use eurothane paint with ceconite these days. As alluded to in an earlier post, the FAA isn't so much concerned with post-crash fires as people dropping cigarettes.

Is that a particular brand of paint from Europe?? o_O
 
Oops... had euro on the brain from writing an article on European electrical standards in another forum.
 
Urethane, in case someone doesn't know what eurothane is
 
The only approved urethane paint on Ceconite is Randolf Rand-o-thane, which usually follows coats of nitrate and butyrate dope. That’s why Stits became so popular. Their vinyl-based coatings aren’t flammable. Air-Tech and Superflight use epoxies. Stewart’s is water-based urethane. Not many guys I know choose Ceconite these days. FWIW, a Cub I finished around 2010 used Ceconite and dope. My current Cub has Stits and Aerothane.

And, given that Ceconite is Dacron Polyester just like Poly... and Superflite - the difference is in the choice of coating systems, not the fabric.
I've had good luck using Poly-Tak to glue things (ie. vortex generators) to my Poly... finished fabric.
 
I have used Weldwood Contact Cement and it works great. It is stocked by Lowe's, is fairly inexpensive, and holds up well in high heat environments. Do not use the environmentally friendly versions because it does not hold as well and has a longer drying period. For carpets and to hold foam on the seats, I use the 3M aerosols either 77 or 90.
 
Beware of solvent-based adhesives. They may release the finish from the ceconite. Aerosol contact should be fine but I’d avoid anything that brushes on.
 
Super Seam II cement is the adhesive specified in the Ceconite process STC. Dunno if it works on Vinyl.
