What happened
During a takeoff maneuver, the aircraft experienced a loss of power. While attempting to maneuver back toward the airport, the aircraft struck the terrain, resulting in an impact with the ground and a subsequent post-accident fire. A witness observed the aircraft flying just above power lines, noting that it turned east and then descended further while turning back toward the north. The aircraft reportedly impacted the ground on its left wing followed by its nose, spinning and bursting into flames upon impact.
The pilot sustained fatal injuries. Emergency services were notified at 14:40, and fuel logs indicated the aircraft had been last fueled at 14:29. An examination of aerial photography confirmed that suitable emergency landing fields were available in the vicinity of the airport.
The investigation
Investigators established continuity to all control surfaces and both engines. Mechanical testing revealed thumb compression was present at all cylinders. During magneto testing, all magnetos produced a spark except for the left magneto of the right engine.
In the left engine's carburetor bowl, investigators discovered a liquid containing water and a flammable aviation fluid. This liquid also contained mineral matter, plant matter, fibers, glass-like particles, metallic particles, and unidentified particles.
An examination of the carburetor inlet screens showed significant debris accumulation:
- The right screen mesh was approximately 60% blocked.
- The left screen mesh was approximately 30% blocked.
- The cylindrical screen's round end was totally blocked.
Both propellers showed witness marks indicating low blade angle, but no other anomalies were found. The left governor was tested and functioned normally, though the right governor was not tested. The aircraft's annual inspection had been completed on July 21, 2000.
