Transponder

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.

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.
