Incident Overview
According to the investigation, the pilot aborted two takeoff attempts after noticing a 'roughness' in one engine. Following subsequent ground checks that failed to duplicate the roughness, the pilot proceeded with the departure.
Loss of Engine Power
At an altitude of approximately 300 feet above ground level, the left engine began to surge. The pilot reported that the right engine 'seemed to be delivering no power either and I could feel the plane decelerating.' In response, the pilot turned the aircraft to avoid a housing development.
Witness Account
A witness stated that the left wing dropped and the aircraft dove into the ground at about a 45° angle.
Injuries and Damage
Both passengers sustained serious injuries, while the pilot was killed.
Investigation Findings
The investigation failed to reveal any reason for the loss of engine power. The official probable cause for the first occurrence (loss of engine power) was listed as undetermined. The second occurrence (in-flight collision with terrain) occurred during the climb to cruise phase of operation.
