Incident Overview
An aircraft experienced a loss of engine power during cruise climb at an altitude of 10,400 feet. The pilot executed a forced landing to a field. After the power loss, the pilot attempted to restart the engine, but the restart was unsuccessful.
Damage Assessment
During the forced landing, the aircraft sustained structural damage. The left wing and right wingtip were damaged, the fuselage was wrinkled, and the firewall was buckled.
Examination Findings
An examination of the airframe revealed no anomalies. Inspection of the engine's dual magneto found internal corrosion. No other anomalies were noted with the engine. The magneto was subsequently bench tested and found to be operational.
Conclusion
The investigation did not identify a specific cause for the power loss. The dual magneto showed corrosion but functioned normally when tested.
