My take is that once a transponder acts up like that, it's time to have it
bench checked. With a light aircraft panel mount, the owner could certainly
remove the unit and take it to the avionics shop.

Doesn't removing the transponder from the tray disconnect it from the
static system and thus require a re certification under 91.411(2)
before it can be used IFR in controlled airspace?

Correct. I missed that point but it was gnawing at me. Then again, I don't do
stuff like that so I have no need to know. I leave it to those who hold the
tickets.

My my perch it indicated either an igorance or predisposition to disregard the FARs. You are very kind to conclude that it simply did not indicate any kind of disregard for
the FARs.

Asking any question implies ignorance - not knowing the answer. It also
implies a desire to find out the answer. If he had a predisposition to
disregard the FARs, he would have merely pulled the panel himself and
attacked the offending microswitch with a fork.

I see it differently. Your assumption disregards possible damage to the unit by just going at it. He asked here because this place is anonymous. In reality, if he felt he was
in the clear he would have asked around in person at his airport.

I don't think you know why he asked.

As for anonymous, the internet is anything but anonymous.

If it were me, I would ask here because it is easy, asynchronous, and
one can get quite a bit of useful information. It is also
self-correcting inasmuch as bad advice is usually contradicted pretty
quickly (though good advice is also contradicted), and by reading a
bunch of replies one can get a good sense of whether the proposed course
is worth pursuing.

Exactly. In order to get good advice from researching the 'net (which
includes asking questions on usenet), one has to have a finely-tuned bull****
detector. This entire thread is a perfect example of why, when it comes to GA and the
FAA/FAR's:

#1: What's legal is not necessarily safe.
#2: What's safe is not necessarily legal.

... or more eloquently as a friend of mine puts it, "Hi, we're with the FAA
and we're not happy until you're not happy."

True, I don't know for certain, but I have a pretty good hunch.

At the level of this forum it effectively is quite anonymous.

Maybe someone should start an avionics maintenance forum. ;-)

I'd use a needle so you can dig into the tip (if visible) and move it into
position. If it's a mode S transponder, don't do anything. It'll probably
snitch on you during your next flight.

And remember the old Navy saying: If at first you don't succeed, get a
bigger hammer.

My King KT-76A transponder has a stuck "Ident" button.
It stuck when activated for ATC on the last flight and the button appears
to have colapsed sideways underneath the cover panel. It is no longer
visible in the opening now. ATC says the unit indicates an "Indent"
signal presently.
Does this require an avionics shop to repair or could it be a simple
matter such as removing the unit, then remove the cover plate and look
for a colapsed return spring?
Thanks,
Tom
Can you still see the button inside the panel?

The plastic button usually just pushes on the switch below it, if you
pushed to hard the button sometimes gets lodged underneath the panel. If
that is the case just get a paper clip, open it up and use the end to see
if you can realign the button so that it pops back through the hole in the
plastic plate on the transponder. Then don't push so hard the next time
you ident.

If you have to open up the unit best to have the avionics tech do it
unless you are familiar enough with the unit to try it yourself.
