SCOTT 3200 Tail Wheel

[210TC]

A patent is good for 20 years. After this time anyone can reverse engineer this product and use it in place of the original. The Faa will accept this as an original replacement much like generic drugs. My theory is like a double reverse. A copies B makes a couple of improvements that do not effect structural integrity (no engineering required) A seeks approval to use this copy on lets say a Maule. I reason that B would in effect (acceptable data??? being part of it)be able to share the same spot as A. Especially, if B contains any new pieces now used in A. A cannot be patented. It can state “patent pending” like millions of products, yet they never receive a patent. This may be an example: AN bolts are made by multiple companies. As lone as the bolt fits the original approval standards then the manufacture is irrelevant as long as it is pma approved.
A profits from selling his new product in an untapped market, the maule. He also gains profit from providing parts for B. Without the market for both A and B, A may not survive. Certainly, A would be more expensive without B.

I assumed it was a Scott

I will have to look for a data plate when next I visit "Martha the Maule"

If it is a Scott is it legal?

It is begining to sound like it isn't.

What came on a 1974 M5-210C from the factory?

What I believe the bottom line is.
Scott isn't approved, period. try legalease all you want, it ain't approved
Shouldn't be hard to gain approval, but as is, it ain't approved, until approved, your illegal with whatever that means.
BD, I believe pretty much invented the modern steerable tailwheel, or maybe it's the modern steerable breakout tailwheel, I honestly don't know which. I can assure you, nothing but a Maule tailwheel was ever put on a production aircraft that he ever built. I mean he invented the concept, what would you expect?

Another example, Avia propellers are Hamilton Standard, I believe some new Avia props are identical, but you aren't taking a Ham Standard off and installing the identical Avia without some form of approval like an STC or similar.
PMA = parts manufacturing authority, just means your allowed to manufacture airplane parts http://www.faa.gov/aircraft/air_cert/design_approvals/pma/
TSO = Technical Standards order, or standard part, don't confuse something like a tailwheel with a bolt or cotter pin http://www.faa.gov/aircraft/air_cert/design_approvals/tso/
Long version of TSO http://www.faa.gov/aircraft/safety/programs/sups/standard_parts/media/standard_parts.pdf

Duane-
If installation not already approved it's a no brainer in FAI with the Feds.

That is pretty much what I thought all along.

See you when I am back in town.

Here is how things shake down for us on the PMA side of things or how we got started anywho.....

We started with our STC'd Fork kit to change your 3200 series tailwheel into a Bushwheel Tailwheel, and buying Scott parts soon became a PITA cost wise and quality wise as well, so we had a few conversations with Scott to purchase the TW side of things and that didn't pan out. We then started to build our own parts to make thinks easyer for us to put the kits together. and then we decided to build full assemblies because the prices were getting WAY out there on the Scott parts after En Aerous bought them out. Now we tryed to STC the Scott tailwheel on the Maule as to relive some pressure on all of us to have leagle parts on our Maules but the FAA would not allow us to do it so we PMA'd and STC'd our own and the great people @ Maule then were able to put the tail wheel on the TC. In short we tryed they put up a road block and we went around it.

GREAT NEWS...........................
Just spent about 30 minutes with Faa inspector.
A Scott 3200 tail wheel can be approved in three ways.
1. By STC/ or on TC
2. By Maule factory suppling a letter that the Scott tail wheel is a "like for like" substitute for the already approved ABI 3200 tail wheel, which is now on the original equipment (TC) list.
3. IA can sign off Scott as a "Direct Replaecment" for Oringinal Tail Wheel. Since, ABI 3200 is on TC it is considered original equipment. Again, "like for like," since the parts sold by ABI are approved parts for the Scott you cannot get a closer match-up. IA makes "MInor Alteration" note in log book and you have the blessing of the faa.

I remembered this in another situation. I took out a Transceiver from one manufacture and installed another one from a different company with some additional goodies. It was completed with Faa approval as a minor alteration since the aircraft was not being structurally altered and was considered like for like.

Sorry, I left out the fourth way: Field approval

Wup, hopefully, this will add to your bottom line as those of us that have/had illegal tailwheels will repair them with your new parts. Face it, everybody wants to remove the maule tail wheel. No disrespect to Maule.
My 3200 was installed long before I purchased. I had no idea it was not approved

Same here, my M 5 came with the 3200 on it and I only realized that it wasn't approved after I had done and review of all the paper work that came with the aircraft.

I will correct the situation asap.

"Face it, everybody wants to remove the maule tail wheel. No disrespect to Maule."

Hadn't heard that before. What's wrong with it after all these years?

Terry,
good question...I installed one on my Taylorcraft many years ago and had no problems. As a matter a fact, I was going to remove that t-wheel from the Taylorcraft now owned by my daughter and install it on the Maule. however, I can now keep the 3200 on the Maule without surgical proceedures. Anyway, I have only heard (hearsay) on this site and elsewhere people experiencing more problems with the maule v. 3200.
I will also say the 3200 looks much cooler.

Are people happy with the ABW 3200 fat tire?

It would look nicer on my Maule than the Scott
