I am operating a Mooney M20K 252TSE, mostly IFR, that is equipped with conventional King avionics (e.g. KI-256, KCS55A, a KAP150 autopilot). In Altitude hold mode but not in Heading mode I frequently experience a sudden and violent pitch-up attitude (this happens from time to time, on almost any flight after some time). This is quite frightening and obviously immediately I disengage the autopilot. The plane always takes the nose up never down. After disengaging the autopilot the plane is still in trim. Does anybody have an idea what may be the cause of the problem? I hear that either the KAP150 computer or the KI-256 could be the problem, however, maybe others have experienced the same problem.
