any reputable mechanic will check the part numbers to make sure it is an
"approved replacement"..

ask your buddy to go through his logbooks and get the yellow tag

Ok, let's say my TSO'd Attitude Indicator (AI) in my Cherokee goes
belly-up, and my friend just happens to have one he removed from
his
machine a month ago as part of a complete panel upgrade. We both
KNOW
the thing works fine and would solve my problem.

What's the ramifications of just having it installed in my
Cherokee?
Is it OK without a yellow-tag? If not, why not? Isn't there any
discretion on the the part of the mechanic to install a part he has
observed as functional in one airplane and put it directly in
another?

I hear if you ask an instrument shop to check it out and yellow-tag
it, they will often refuse unless you pay them to do a COMPLETE
OVERHAUL. Is that true?

If the part is a certified one (doesn't have to be TSO'd) and is
listed as a direct replacement, all that is necessary is a proper
log
book entry.

An instrument shop can inspect and return the part to service
"yellow
tagged". They would probably insist of tweaking it which will cost
you the same as having it o/h'd. If it works, put it in. When it
dies, replace it.


Stu,

Thanks to you and the others for your post. What I need to find out
is what to tell the mechanic when I hand it to him (with no
yellow-tag).

It sounds like all I have to say is that the gyro is listed as a
direct replacement (I assume a Sigma-Tek 5000B-36 IS a direct
replacement), that it is in working condition, so JUST INSTALL it and
make a logbook entry.................please...

Does that sound correct?

By the way, where WOULD I find a list of approved replacement attitude
indicators for an Arrow II?

BT,

In the REAL story, this instrument was bought from a guy who acquired
it as part of a fairly complete RV-6 homebuilt package but didn't need
either the AI or the DG, so he's selling them to me. Unless the guy
HE got the RV-6 package from has a yellow-tag (or manf'r tag), I doubt
I'll be able to acquire one. I WILL try and track down the guy he got
it from, anyways, on the outside chance he might have something
although it's been over a year.

I was just hoping to avoid the hassle and get my mechanic to install
the thing, and needed some advice on what resistance I might get from
him.
