KT-76A Airworthiness Directive
 

Here's one to watch out for; FAA AD 98-14-03. It's on the KT-76A, which is on many GA aircraft in the UK. We had missed it, our local CAA surveyor pointed it out to us and he reckons it's still outstanding on many units out there;

AlliedSignal Inc. KT 76A Air Traffic Control (ATC)

Well worth a quick check to see if any of your aircraft are affected. If the serial number of your unit is between 93000 and 109999, and has not had Mod.7 done, then it needs sorting.
