Honeywell KFC-225 autopilot - what could cause this failure?

Hi Peter,

The mpeg didn't play for me but just a few thoughts:

Since they say they couldn't reproduce it on the ground, could this be a
noise issue? Possible sources would be the radio, a transponder
transmission, engine ignition, maybe a motor driven trim, fuel equalizer
pump if you have one. Just think about other stuff on your aircraft that
produces either RF or commutation noise and comes on automatically and
possibly unnoticed by the pilot.

I have seen such noise become a real problem with composite structures.

In the two years from new I have had perhaps a dozen failures.

It's not someone leavnig their phone on in flight is it?
That's been attributed to APs going a bit funny on
more than one occasion.
