I have a 337 form stating the installation of the Peterson auto fuel STC, but no actual STC on file.
Peterson said they would send me the replacement STC for 1/2 of the price of a new STC.
Do I need the paperwork or is the 337 enough?

You need the STC..... at least that's what they've preached to us at the IA seminars for the last 20 years.

Why would there be a 337 form? I thought that there were no major modifications required for Peterson's Auto Fuel STC. ???

There are no major modifications for the Pererson STC, but is is still an issued STC. All STC's require a 337 filled out and sent in to Oklahoma City..... The STC is the approved data so it is not a "field approval" 337, just a 337 stating that the mod's were done according to the STC "data"....

I had to bite the bullet and buy the paperwork for my 150. My mechanic wanted it even though the stickers were on the plane. Peterson's actually tried to talk me out of it because of the ethanol being put in the gas. Are you sure you can buy straight fuel now because the STC won't work with E10? Good luck

Thanks for the help.
I hate to spend $172.50 for a copy of what has already sold to the plane.
We are lucky to have clean fuel at a Pacific Pride a couple of miles from the airport.

That is a ton of money, and it really adds up! I was just looking at the Petersen website. It says "Over 34,000 Mogas STC's sold WorldWide since 1983". If the average price is around $300, that's just over $10 million in sales!

Last months Pacific Pride bill for super unleaded (non eth) was $3.71 per gallon average for the month.
That's probably somewhere around $1.80 per gallon savings over avgas.
100 gallons will pay for the STC copy, but I still don't want to pay that much for a copy.

Once that mogas is burnt who will know You think the mogas police will investigate you

Was thinking the big "what if".
You're right, I'm sounding like a big puss here.
Don't sweat the small stuff.

I bought a C150/50 whch had a mogas STC done when it was still 100 hp. I called EAA & they sent me new STC paperwork covering the Lycoming 150 installation & charged me the difference between what was paid before ($1 a horsepower) and current price ($1.50 per horsepower)-- that seemed plenty fair to me. Sounds like maybe that's how Petersen is treating your request. Other than satisfying your IA at annual time, the paperwork is useless unless you crash with mogas in the tanks & hurt someone-- you'll likely get hung out to dry if all your paperwork isn't in order. 50% seems steep just for copies of the paperwork but if ya wanna be legal sounds like that's what it'll take.
Glad to hear you have E-zero available locally.I believe they sell cargas on the field at Lebanon too. I have one station close to home (CFN, which I believe is allied with Pacific Pride)-- premium only in E-zero, about $4.20 or so. Also a local airport (Oak Harbor/Eisenberg) sells 87 octane E-zero mogas for about $5.

Airport manager asked me to pump some 100LL for some guys going home from Oshkosh and charge them $4.20 a gallon. That fuel was layed in a year ago and with crude crashing right now, the next load should be about the same. Will be interesting to see.

100Ll is supposed to have a longer shelf life than car gas, but a year? That seems like an awful long time to me. They don't sell much avgas there, sounds like.

My airplane never had a 337 filled out when the Auto Fuel STC was installed, so I called Peterson Aviation and talked to Mr. Peterson himself. He found my plane in his database and sold me replacement fuel tank stickers, the metal band to install around the oil filler tube neck, and the STC paperwork for $20. About 1/2 hour labor for an A&P I/A to verify installation and fill out a 337.

Thanks gep,
I did email and received a reply from Todd Peterson saying he would send me the paper work for half price.
I would have gladly paid $20 or maybe even $50 for a copy, but not $172.50.
I say, I have a signed logbook entry and a 337 form.....I'm good to go.
I'll call and see if I get anywhere.

It always amazes me that airplane owners will spend tens of thousands on an airplane, and then do everything they can to avoid having to pay a few bucks to make it legal.

Look at it from the perspective of the STC holder: You're asking him to sell you the only thing he has to sell for pennies on the dollar.

Your airplane already had the STC "installed"?? Okay, whose job was it to ensure that ALL the paperwork, ie: the STC itself, was in the airplane logbooks when you bought the airplane? That's why we do pre-buy inspections.

Remember the old saw "Buyer beware"??

I know this sounds harsh, and I really don't mean to be, but from the perspective of the STC holder, who's selling paperwork......

I hope you don't find this offensive. Trust me, I've been in a VERY similar situation, and I know it's aggravating to have to pay AGAIN for something you THOUGHT was taken care of.

Have you gone back to the guy who sold you the plane, and asked if he's found the STC paperwork laying around, cause you're going to have to pay for it AGAIN otherwise?

Please, the STC is a piece of paper. If the STC company wants great word of mouth advertising they should fork over a new one for free. Assuming the N # of Terry's plane is in his data base. I am a business owner and I know how valuable good advertising is.

Good day

You just gave me an idea, I'll just back charge the guy that did the pre-buy
He will be camping with us this weekend, I'll see how he feels about that.

All the placards are installed, the paperwork is done, just missing one piece of paper.

The $340 originally paid for the STC must be the best deal going for anything you could purchase for an airplane.

I agree, they keep track of the N numbers issued STC's. If that N number already has the STC issued, IMHO they should send a duplicate set of paperwork for free. If the STC for that airplane needs to be upgraded like mine did (bigger engine or whatever), it's a different story. Like I pointed out, EAA upgraded mine for the bigger engine installation & charged me the difference between todays price & what was previously charged, and I was OK with that.
