Flight and Incident
A commercial pilot was conducting a night cruise flight at 6,500 feet above ground level when the engine began to malfunction. The pilot informed air traffic control (ATC) and stated that an airport was straight ahead at about 11 miles. ATC advised the pilot that the airport was 15 miles away on a heading of 275 degrees. The pilot then reported that the engine was dead, declared an emergency, and initiated a forced landing toward the airport.
Forced Landing and Collision
During the forced landing attempt, the airplane collided with trees and terrain roughly 6 miles east of the airport. The impact was followed by a postcrash fire that consumed the entire aircraft.
Engine Examination
Post-accident examination of the engine revealed damage to the number five piston crown structure, consistent with detonation or pre-ignition damage, though the reason for this damage could not be determined. Additionally, the number two connecting rod and its bolts had failed due to an oil distress event.
