Accident Sequence
The pilot aborted a takeoff due to poor acceleration and subsequently dropped off passengers. One passenger, a pilot, advised the pilot to have a mechanic inspect the aircraft before further flight. The pilot agreed but proceeded to take off. Witnesses observed the aircraft climb to about 15 feet above the runway, descend approximately 10 feet, and begin a left turn. During the turn, the left wingtip dragged in the dirt, rupturing the left wing's fuel tank area. The aircraft then collided with the ground, spun around, and came to a stop engulfed in flames.
Investigation Findings
Examination of the flight control system and propeller revealed no mechanical anomalies. The engine showed mechanical continuity throughout, but cylinders number 5 and 6 had their respective camshaft lobes worn down so that their valves would only open about 30 percent of the manufacturer's prescribed distances.
The FAA's Civil Aero Medical Institute (CAMI) toxicology report showed high levels of prescription narcotic painkillers in the pilot's blood and liver fluids. Review of the pilot's records from CAMI revealed a history of coronary artery disease with angioplasty performed on August 10, 1994, and a history of low back pain for which he was prescribed large amounts of narcotic painkillers. The pilot had not been issued a current medical certificate.
