What happened
Shortly after takeoff, at an altitude of approximately 30 feet above ground level (AGL), the aircraft entered a right turn. The pilot reported that the airplane failed to respond to control inputs. In an attempt to maintain control, the pilot reduced power and pitch.
During the maneuver, the right wing struck the ground, followed by the right main landing gear. This sequence led to a ground loop before the aircraft eventually came to a stop. The flight in which this accident occurred was the first flight of the aircraft following an annual inspection that had been performed on July 19, 1996.
The investigation
An examination of the aircraft revealed that both ailerons were rigged improperly. Investigators found that the aileron control cables had been attached to the wrong side of the bellcranks.
