I am in need of some STC supporting documents for the 6A-350-CR1 engine. All of my documents where lost in a vehicle break in. My engine was installed under the Seaplanes Inc. STC. According to the FAA I can use another airplane's STC paperwork as long as I have my form 337. If someone could get a message to mountainmike I would appreciate it.

Thanks

Might want to order the CD for the plane from the FAA. That is what I did when documents were missing for a float installation on my Champ.
Other than that Rhyppa may chime in if he sees the thread. He had a Stinson with the 220 Franklin and may know its where abouts to try and help out with paperwork.
Good luck

I doon't think the FAA would have any of the "STC supporting documents" (blueprinnts, specs, etc), at least in the aircraft file-- they would just have the filed 337. Did you look up the Seaplanes Inc STC number? Maybe someone else owns it now and can help you out.

I think the Seaplanes STC's for Franklins is now owned by Franklin Aircraft Engines, Ft Collins, CO., 136 Racquette Dr., 80524

PM sent.

Tadpole has all the paperwork now, but I believe he can get you what you need.

Shoot me a PM with your email address and what' you're looking for. I have a 220hp 108-2.

Unfortunately the FAA will not release any information on STC's. I went around and around with them. Even though the Franklin Engine Comapny no longer exist(and the STC is basically in limbo) they will not release the STC Data. I have the data disc but it only shows 337's and not the POH supplement that's required for flight. I will keep a digital copy of all paper work from now on. I have however found a few 220 owners that are going to help me out. Thanks for the help.

Seaplane Inc no longer exist. Their building burned years ago and the company split up.

I have a good friend who has a 220 F 108-3 and I may be able to get the docs from him as well.

I will have a try at it.

I'll volunteer the IA/AP who did my install. He happens to be the proud owner now as well.if you haven't sorted this out yet, PM me and I'll give you his contact info.
Cheers,
