I am in the great search for paperwork for the bush STOL kit that is on my 1959 Cessna 175. I purchased the plane from an older gentleman who was not very meticulous with paperwork and I suspect I am missing a logbook which he cannot find. Anyhow I am looking for the paperwork for the SA1371SW Bush STOL kit. I am more than happy to pay for copying and shipping of the information. I do have the certificate from the FAA(http://www.airweb.faa.gov/Regulatory_an ... 1371SW.pdf) but I need the data sheets to straighten out the 337.

Thanks for your help!

You can get a CD from the FAA with all the records for your aircraft. Costs a few bucks. If it was properly filed, it should be on there.

Thanks for the suggestion! I already went that route and there is no 337 there. I'm pretty much at ground zero attempting to get this legal. I have spent the last month attempting to contact Bob and Barbra Williams in KS for the information as they own the STC do we can get the appropriate information for getting the 337 filed but they haven't chosen to respond. I hear they are hard to get ahold of as I have seen that both on the forums and from the FAA. As this STC covers many aircraft in the Cessna line I would assume someone has to have the paperwork

You are probably chasing ghosts at this time. They have been basically non-communicative for years.
I tried to contact them about ten years ago and had no success even then.

Rumor is that they (Mr. & Mrs.) may have split into separate ways and companies.
Rumor also has it that the "2" companies share the same office and phones.
He answers one, she answers the other, or something like that.

I have a Bush conversion on my 170 and was only able to get a full set of documents from the fellow that started Avion Research. Had the papers scanned, printed, and put on a disc. I have them severely stored somewhere. Do not know if they would even help with the 175. Fortunately my 170 at least came with the 337s all done.

The last person I heard of that may have any information is Harry Delicker at Delair in Porterville Ca.

He also holds several similar STC's and may be able to help. For a cost obviously.

Have you tried the "International Cessna 170 Association?" Seems they used to have some similar threads of frustration with the Bush folks.

Better luck

I'm keeping on trying to contact the Williams. I won't stop until I have the needed documentation.

I called up Harry this afternoon. Very nice guy! He didn't have any information about the STC's for the cuff, fences, and tips. He said everyone keeps thinking he has them but he doesn't.

I'll drop a line to Avion and see if they can hook me up. Thanks for the suggestions!

I did also send an email to the 170 Headquarters as I hear they do have some paperwork available.

Chris,

If you do happen to come across that paperwork I would be more than happy to compensate you in order to see it. I spoke with the FSDO today and they said that they were familiar with my situation with this company and would accept just the data as long as my IA can confirm that the installation is correct.

I did drop a line to the Avion folks and am waiting for a response. Perhaps they will have something too.

The 337 should be turned in to be legal, but I don't think there's any requirement to turn in any supporting paperwork such as the entire STC package with it. I have seen airplane records where the owner had the 337 but not all the STC paperwork. In fact mine is like that-- it was wrecked in Alaska in 1995, ended up at the Omak salvage yard, & was resurrected about 10 years later. I'm kinda surprised that any paperwork at all managed to stay with the airplane.

Sorry, but I had jumped to a concussion. Since I was only familiar with the Bush's 180hp conversions, (STOL) I assumed that was what you were looking for. That is what Trevor and I both have/had. That was back in the mid. 80s. Loong time ago. Bush folks may be long time gone.

Not sure Trevor is still in business with his Avion stuff. Will have to go buy where the shop was and check. IF, he is still there, then I will check with him. Read somewhere that he is also now hard to get a hold of. I know that business was slows with him at the downturn. He was only keeping a couple of folks in the shop while he went back to work as a Mech. Eng. somewhere.

Sorry for the assumption and limited knowledge of what all the Bush folks had done.

Chris

No worries! I appreciate the help thus-far.

For a history lesson, the Bush people had 3 different STOL STC's for the Cessna single engine airplanes pertaining to installing a new cuff, wingtips, and stall fences. From what I can tell not many people have their stuff, and that's not a bad thing due to the lack of product support.

If I can get this one issue cleared up, I'll be on easy street.

The story on the plane is that it was practically sitting for 30 years. At some time, the STOL kit was added to it and from what I can gather due to some bad clerical mishaps, the 337 never got submitted. When I purchased the plane it was hard enough to get the log books after 30 years. It took nearly 2 weeks for the 90+ owner to find the documentation he could find. On the plus side, in those 30 years the plane was taken care of and most things were kept up to date. Other than repairing some instruments and updating the avionics, she's good to go.

I'll talk to my IA Monday and we'll get the paperwork processed as soon as possible with the limited paperwork I do have. If hotrod150 made it work, it gives me confidence that we can make something good happen.

All the 337's for the mods on my airplane had been turned in,it was all signed off & legal -- just some of the STC paperwork for the engine conversion turned up missing by the time I bought it. I'm sure that with a good IA (who's not afraid of a little paperwork), a cooperative FAA inspector, some time, & maybe a little money, most paperwork issues can be ironed out.
Bob Williams of Udall KS sold three basic mods for Cessna as far as I know-- a STOL kit (leading edge cuff), tailwheel conversion for C150/152, and engine upgrades for 150/152 & 170/172/175. I have one of their sales brochure from years ago-- the engine kit was marketed as "Avcon", the t/w & STOL kits under both the Avcon & Bush Conversions name. The name "Martin Aviation" is also on the STOL kit brochure.
FWIW the "Texas Taildragger" C150/150 kit uses an Avcon engine mount & muffler. Harry Dellicker of DelAir (Porterville CA) now holds the STC's for the three "Texas" C150 conversions: tailwheel gear, 150/180hp engine, & 40 gallon fuel tanks. But I don't believe he is marketing them at this time, he's mainly into upgrades for the 170/172/175 series cessna's.

I share the same concern as all Bush conversion STC holders. I converted two Cessna 150 many years ago and now cannot get hold of the Mrs. Williams as I need some damaged parts to be replaced. I need to replace the engine mounts and if anyone has some information on the weights added on the rear bulkhead. Dimensions & net weight of the weights added. can anyone help?
