King KAP 140 auto pilot problem.
We have a 2000 Cessna U206H with the King KAP 140 auto pilot. On pre-flight the ailerons did not move freely, kind of dragged, and we found that the server motor clutch was catching intermittently. Has anyone had this problem before and how was it solved? We've run the AP on the ground and it seems to work normally and disconnects normally, but still the clutch catches once in a while when everything is off.
