What happened
During the initial climb following takeoff, the aircraft experienced a loss of power in the right engine. An observer noted the sound of an engine malfunction accompanied by visible flames emanating from the right engine cowling. After reaching an altitude of approximately 200 feet, the aircraft entered a turn and subsequently descended through a small grove of trees. The flight ended when the plane struck a pasture, where it caught fire. The pilot, who was the only person on board, was killed in the accident.
Findings
Investigations into the accident revealed several critical factors regarding the aircraft's configuration and mechanical state. At the time of takeoff, the aircraft's gross weight was approximately 11,050 lbs, which exceeded the maximum certified weight limit of 9,700 lbs. Additionally, the center of gravity was positioned behind the aft limit. The pilot was reportedly aware of the weight discrepancy prior to departure.
Mechanical analysis of the engines showed that the propeller on the left engine was in the feathered position, while the right engine propeller had not been feathered at the time of impact. A detailed inspection of the right engine determined that the failure of the number 3 cylinder intake valve due to fatigue caused the engine power loss.
