West Jordan

The pilot stated that after parachutists egressed from the airplane, he returned to the airport and found that he did not have a green down-and-locked indication for the left main landing gear. He stated that he executed emergency procedures and did two fly-bys over the runway. Ground personnel stated that the landing gear appeared to be down-and-locked. During the landing roll, the airplane began to slide side-ways, and the right main landing gear began to collapse and eventually separated from the airplane. The left main gear also collapsed as the airplane slid to a stop. After the accident, the upper torque knee on the left main landing gear was found broken. The failure mode of the upper torque knee was not determined.

Investigation revealed that the pilot aborted two takeoff attempts due to a 'roughness' in one engine. Not able to duplicate the roughness during subsequent ground checks, the pilot departed. At an altitude of 300 feet agl the left engine began to surge and the right engine, according to the pilot, 'seemed to be delivering no power either and I could feel the plane decelerating.' The pilot stated he turned the aircraft to miss a housing development. A witness stated that the left wing dropped and the aircraft dove into the ground at about 45° angle. Investigation failed to reveal any reason for loss of engine power. Both passengers were seriously injured and the pilot was killed.
