The accident airplane had just undergone avionics maintenance and was released to the pilot/owner about 30 minutes prior to the accident. According to the technician who conducted the maintenance, the autopilot system operated correctly, and he instructed the pilot to "check his trim before he left, as it runs during ground checks." Prior to engine start, the pilot noticed that the pitch trim was set to the full airplane nose down (AND) position. He reset the trim to the takeoff position, and ensured that the autopilot was off. The pilot reported that during the takeoff roll, the airplane did "not feel right," and he rejected the takeoff. The airplane overran the 3,347 foot-long, dry, asphalt runway, traveled down an embankment, and came to rest in a shallow ditch. Post-accident examination and testing of the airplane elevator and pitch trim system by an FAA inspector confirmed elevator and manual pitch trim control continuity, and the controls were observed to be functional and directionally correct. The electric pitch trim and cockpit pitch trim indicator were also observed to be functional and directionally correct. One witness reported that about 10 minutes elapsed from the time that the airplane was pulled from the maintenance hangar to when the pilot reported the accident.
Probable Cause: The pilot's failure to ensure that the pitch trim was properly set for takeoff.
