Replacing fuel cut-off valve with non-a/c part???

You really don't understand, do you John? The process to approve this part
is NOT a simple 337. A 337 means you have approved data to make the
modification.

Oh, no, sir. You submit a request to the local FSDO inspector, who transfers
it to regional engineering, who passes it on to Oklahoma City, who bucks it
up the ladder to Washington DC for a policy decision, while you wait, and
wait, and wait for an answer.

This is a frikkin' low horsepower single engine airplane out of the 1930s.
If the valve the person is suggesting that they use is available at the
local hardware store, it is far superior to ANYTHING that was available in
the middle of the last century.

Put the sumbitch on and keep your mouth shut.

If you were to replace the fuel shut off valve with
something not certificated for that aircraft you would need a Form 337 to
gain
approval.

You're a bad person.

But I totally agree. ;-)

The only way you get busted is if: A) The airplane crashes because the valve
failed and B) You open your mouth.

Actually, a crash for any reason is bad if it results in the uncovering
of the unapproved part.

Especially for the widow, and what little if anything will be left of the
estate once a lawyer finds out about the automotive valve.

It always amazes me how people insist on taking a chance on having a lawyer
walk away with your life's savings and assets just because they're too damn
lazy to track down the right part...

Are you totally clueless? Have you never heard of proximate cause as a
condition precedent to getting into court on a personal injury or wrongful
death lawsuit?

No, and apparently neither have the lawyers that have obtained multimillion
judgements against companies like Parker-Hannafin even when the NTSB
concluded their products were working just fine (Carnahan case), or when it
was absolutely crystal clear that the crash was a result of the captain
deciding to commit suicide (Silk Air flight MI-185).

What was it that you were saying about clueless? How are things in La-La
Land these days?

sheeshh....

Having done a fair amount of plumbing repairs in the last fifteen years, I beg
to differ. Pay *close* attention to the country of manufacture. If the new valve
is made in the US, Canada, or just about any European country, Jim's statement
is absolutely correct. One made in Indonesia *may* be satisfactory. Having seen
the failure rate on the Chinese shutoff valves which I've put in, there's no way
I would install something made in Asia in my fuel system.

And make absolutely sure that it has the warning label to the effect that it
contains substances that are "known to the State of California" to cause birth
defects. That substance is lead, which is required in the manufacture of quality
brass valves.
