Identifying Razorback or Ceconite 101
How do you identify Razorback or Ceconite. I looked at a 1987 M-6 today. The finish was very brittle and cracked when flexed. Looking from inside I could not see any PMA stamps on the fabric like I am used to. My 140 wings are covered with PolyFiber and the PMA stamp is easy to see. I have had the same experience with Ceconite. The Maule Service Manual for the ship says it is covered with either Razorback or Ceconite 101. The POH did not say. How can I identify Razorback? Did Maule have some kind of deal with Ceconite where they provided fabric without the PMA stamp?
Any thoughts?

A PMA'd stamp would not be necessary on the original fabric from Maule. Since they are the manufacturer, most anything they do to the airplane is approved by the type certificate. If you recover the aircraft then a PMA'd stamp would be required, unless you obtained a field approval for that specific installation, or the Maule factory did the recover job.

That is what I was wondering about. I understand that Maule quit using the Razorback in the early eighties. I looked at a '87 Maule yesterday and the owner was insistent that it was covered in Razorback. I looked inside the tail for the back side of the fabric and did not see a stamp for anything, maybe he was mistaken(it was his third Maule in 40 years). The cover was very brittle and the finish cracked when the fabric was flexed.
Thanks for the information. This is a great site.

One way that works when it gets bad is to PRESSURE WASH all the paint off fabric which comes off relatively easily once cracked and refinish with one of the later made for fabric paint processes... As you are approaching 20yrs old on ceconite, you're near the end of expected life cycle though, and might not be worth the effort to refinish? But it might get you up to 10 more years, if it'll pass the punch test especially in the existing bad areas?

It's very easy to distinguish Razorback from Ceconite.
Looking at it from the unpainted side, Razorback will appear quite rough. Go to Autozone and look at fiberglas cloth -- that's what Razorback looks like...thick fibers; open weave. Ceconite is a much smoother cloth, like a pinpoint cotton shirt.
