Hi All, I need to replace the backing and suspension straps on my sling style seats in a Stinson 108. The material is a medium heavy canvas cloth and the straps are two inch webbing.
I am having a terrible time finding somewhere to buy certified flame resistant canvas cloth, or any other heavy weight type cloth.
Anyone got a suggestion?

That's quite an article, but it has NO relevance for a Stinson, since the Stinson is NOT a part 23 certified aircraft....it's a CAR3 certification basis.

I was just looking at carpet for my maule project and saw this on SCS website. No idea if it would work but maybe in the ball park?

Make sure you find compatibility of chemicals. On my M6 (old fuselage, not current one), the headliner was made out of non-conforming material in terms of burn certs. So they added flame retardant or whatever, not sure exactly. Turns out it made it extremely corrosive and every steels tube within about 4" of the headliner had to be cut out and replaced after only 5 years.

I started this thread once upon a time. Might be helpful. Still working on the interior.

It’s a long read, but goes into what makes fabric flame resistant and where to send off for testing, I’d wager the same place could probably point you in the right direction, if they didn’t have something for the straps themselves

You're missing the point....a Stinson isn't a part 23 airplane, so the "fire" requirements aren't the same. CAR3 fire requirements are much easier to deal with. Basically any automotive upholstery will easily meet the specs. The aircraft has to only be maintained to the standard that it was certified to. I used to have CAR3's location saved on the faa website, but they've improved it so much that nobody can find anything anymore....I'll have to dig deeper.

I purchased some flame resistant fabric for my Supercub from Oregon Aero. You might contact them.

It’s really not that big of a deal. Several years ago I did the interior panels and headliner in my early 182 which is also CAR3. I just found the materials I wanted and sent them to a flame lab, I think it was Aeroblaze down in TX. They told me how big of a sample to send and quantities, and about 2 weeks and $75 later everything was legal. I selected wool from Pendleton mills for natural flame resistance. Just find a material you what you want to use, pull up the flame test on the internet, and break out a lighter to do a home test. If it seems ok, then send it off, if not, select another material. I found virtually no one will provide flame certs on bulk fabrics they sell. It was just easier to find what I wanted and do it myself.

I redid the fabric on the glare shield in my Maule with a black corduroy I got from a marine canvas shop. They had fabric options that came with flame retardant certs that met requirements for a Part 23 aircraft. Even if the requirements for CAR3 are less stringent, having fabric that meets more stringent requirements shouldn't be a problem. You might want to check with your marine suppliers locally.
