## Probable cause

The pilot's inadequate remedial action to disconnect the autopilot during an uncommanded altitude deviation while in cruise flight.  Factors in the accident were activation of the autopilot; the pilot's lack of familiarity with the airplane's autopilot system; her failure to attain the proper touchdown point during an emergency landing, and delayed go-around resulting in an overrun and collision with trees; the operator's insufficient training standards for the airplane, and the pilot's flight instructor's failure to provide adequate upgrade/transition training in the airplane.
