Aircraft involved
Probable cause & findings
The improper installation of the right rudder control cable by maintenance personnel, which resulted in the pilot's inability to maintain directional control during takeoff.
Factual narrative
During the takeoff roll, an uncommanded left yaw could not be corrected with control inputs, so the pilot elected to abort the takeoff. During rollout, the airplane departed the left side of the runway, and the landing gear collapsed, which resulted in substantial damage to the left wing spar. Examination by a Federal Aviation Administration inspector revealed that a "nicopress" fitting on the right rudder cable had failed, and disconnected from its bell-crank. According to the Inspector, the cable fitting had been pressed with an improper tool or technique at installation. The airplane's entire flight control system was refitted and re-rigged approximately 9 years prior to the accident.
