Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot's failure to achieve takeoff due to a mistrimmed elevator, and his failure to maintain directional control.

Analysis

The accident occurred during the initial takeoff from a private grass airstrip in Geneva, Alabama. According to the pilot, as the airplane accelerated down the runway during the attempted takeoff, the airplane would not climb and he could not explain why. According to the pilot, he elected to abort the takeoff with approximately 400 feet of runway remaining. When the pilot elected to abort the takeoff, the airplane veered off the right side of the runway and collided with trees. Examination of the airplane revealed that the elevator trim was observed in the full nose down position. The right wing was damaged at the root and the right wing spar was bent. The pilot did not report any mechanical difficulties prior to the accident. According to the pilot's operating handbook the pre-takeoff checklist requires the elevator trim be set for takeoff.

Factual narrative

On January 8, 2003, at 1020 central standard time, an Aero Commander 100, N3628X, registered to and owned by the pilot, collided with trees adjacent to the east runway at a private airstrip.

According to the pilot, recent maintenance had been completed on the airplane in Geneva, and the purpose of the flight was to reposition the airplane to his home in Pensacola, Florida. The pilot stated that he preflight the airplane and performed a run up. The pilot taxied the airplane to the north departure end of the private grass airstrip. The pilot stated that the grass airstrip was approximately 2600 feet long.
