KFC150 Autopilot - maintenance manual?

10 Posts

Hello I have a PA 46 and the autopilot KFC 150 it won’t engage and the trim
Light and sound keeps beeping.
By any chance anybody knows what can I check and if somebody have the service manual to repair it.
I appreciated.

This gentlemen charges for telephone troubleshooting, and while I never managed to engage with him he may be able to help.

There should be a small leaflet as part of the STC in the POH which advises on pre flight testing.

I’ve never seen one for the 150.

Maybe @wigglyamp knows?

If I saw one I would very much like it for my 30GB avionics manuals collection (on a private site).

You will need serious electronics expertise, and knowledge of how 1990s avionics hangs together, to troubleshoot this stuff from first principles.

I don’t have a component-level maintenance manual and flight-line maintenance usually is done using the aircraft-specific STC install manual plus the flight-line test set.

The first thing I would check would be the AP disconnect switch and pitch trim switches for correct operation. It’s not unusual for one half of the trim switch to fail and this will cause a failure of the PFT.

I had this issue with KAP140 in DA42.

I had this failure with KFC150 when I owned TB20.
