Wing Cover using PK Screws

Re: Wing Cover using PK Screws

Anybody know how to do the STC process? .

Hank

Yeah, I'm just in the middle of it again. I already got an STC-PMA on this product http://www.ezflaphandle.com and by the end of the year I should have four Piper airplanes added to the original Cessna STC. So yes, I know how to do it and have succeeded.

But the time and effort is significant. The market has to be there, and frankly there are not enough
1) T-craft owners, who
2) would switch from wire to flush screws... especially in the presence of an STC for round head screws, and who at the same time
3) are ready for re-cover

Only the most sick, twisted, hare-brained Taylorcraft lovers would go to the effort, simply because it looks really cool. And if I had to charge $100-200 for the paperwork to do it, there would be fewer yet who would take the plunge.

Next time I cover a set of T-craft wings, I'll probably use that as the excuse to go thru the process and get an approval, but for now I've got two or three other more pressing projects that MUST get done so I can make a living at this before I become homeless.

If Mr. Aguirre wants to hire me tomorrow... on salary... to be one of the West Coast sales reps for the Taylorcraft company, then all that could change. I'm not holding my breath

Bill,
Gee! You do STC's? Who woulda thought!
Now that you have bitten the bait it's funny you would drop the "sick, twisted, hare-brained Taylorcraft lover" lure right in front of me. Good thing I don't need to cover anytime soon!
Looks like all of us got lucky that the STC already exists. All we need to do is resurrect it. Anybody want to cover a set of wings? Those of us with wings waiting to recover in the next few years could look at getting the STC and putting it in the foundation for members to use. This is the kind of thing we should be looking at to build real value in the Foundation library.

I was referring to creating a brand new STC for the flush PK screws and Tinnerman washers, as opposed to an existing STC for round head screws. I knew about the existence of a round head screw STC, and the pop rivet STC.

Forgive the SPAM if you all already know about the Cessna/Piper STC I did, but I was simply responding to your post asking if anyone knew how to go thru the process.

Re: Wing Cover using PK Screws

Pulling your leg Bill. You have been the King of STCs here lately so I was hoping you would jump in with process info. I actually hadn't noticed the difference between the screws, but then, that's why I want the guys who know about these STCs to work out these details before I need to do mine.

The King, eh? Well then I'm going right down to the store and get one of those hokey crowns like Madman Muntz or Crazy Eddie from the old TV commercials, or a crown and a 20 foot long purple robe like that hilarious Bugs Bunny cartoon.

We have a modern kooky sales guy here in LA, "Paul's Big Screen TV", where he ends all his commercials in a robe and crown saying "I AM the King!" I'll have to adjust all my press releases and ads to include this important concept.

Just when y'all thought you'd finally seen the far end of my egomaniacal ramblings

The flush PK screws with Tinnerman washers is actually something I'd try and get certified sometime. There's MANY other people here who have done a lot more fabric work than I, but that idea really seems like it would be an elegant solution and more than acceptable strength wise. As mentioned I gotta go slay the income dragon first, but I think it would be a worthwhile STC to pursue.

I say again, however, that for historically correct restorations and rubber stamp FAA approval, it would be a fairly straightforward thing to go find whoever makes the "Martin Wire" that is not quite right for the T-craft rib, and get them to run off a couple thousand feet of correct T-craft wire.

Wouldn't round-head screws save having to fit VG's?

Re: Wing Cover using PK Screws

All,
BTW, if you like aviation history, my 1929 Model 2 Fleet also has PK screws attaching the fabric on everything but the ailerons and that was from the factory. Not much new in aviation. Mike

Hi Mike,

Yup, screws.... but there is a very good chance your Model 2 left the Fleet Aircraft factory with Reed and Prince rather than Parker-Kalon screws, holding the bag on.
