Geez y'all, with all the arguing, somebody could have found an approved

from a certificated aircraft, gotten the conformity data, submitted a 337
with
details, drawings and instructions for continued airworthiness and most

have gotten a fuel cutoff valve that doesn't leak.

Very true... but several posters seem to continue to insist that not
only are 337s, approvals, log book entries, drawings and the FARs
unnecessary and dispensable (at their sole discretion), but a real
hazard to safe flight.....

Well, nobody has said that, and you act more and more like a rather grim
little troll. Most people are puzzled about all the paperwork and excess
energy unnecessarily expended to replace a part on an aging aircraft, so
they seek out an A&P/AI who is not working on his analworthiness
certificate. (Such as yourself.)

The FSDO in this neck of the woods does not grant field approvals and its
agents have said so time and time again. That's a fact, so why don't you
troll and spam where you'll be more appreciated.

By the way, some friends just replaced the bronze jackscrews on their trim
systems and didn't go through all the anal hoops the lock-sphinctered
hairsplitting like you seem to require out of airplane life. We reverse
engineered them because there was no other source. Much to your chagrin and
pucker-pain, they work beautifully. And the IA's who installed them just
loved them.

In addition I'm personally aware of a mag drive gear from Fresno Airparts
which just had the FAA in a nervous frenzy---because Fresno apparently
didn't go through the hoops to assure the proper Rockwell hardness (It's
soft) and furthermore didn't get it approved and etched 'FAA-PMA' with
permission. And I understand there are thousands of them out there in
service. Now I hate to tell you--- for fear you may swoon and collapse with
a conniption yourself and tear out a sphincter --- but this #36066 drive
gear (price for the legal one: about $500 at ACS) has almost 800 hours on
it -- and not one torn anus. See:
http://www.faa.gov/certification/air.../ACE-98-21.htm
for details on the discomfort at FAA.

Now there's a real issue for you, my analworthy friend. That and somebody
taking a Cub data plate and putting it on a homebuilt Cub-- then selling it
as if it were the genuine item. Go and find out how many catastrophic
engine failures occurred because of those gears out there turning thousands
and thousands of mags and report back with the scandalous results.
