What happened
During a cruise flight, the aircraft experienced a significant loss of engine power, with the RPM dropping to approximately 1900. Recognizing the emergency, the pilot initiated a precautionary landing on runway 27. However, the aircraft was unable to stop within the intended landing area and overran the pavement. It continued beyond the end of the runway before flipping over in a cornfield located west of the airport.
The investigation
A mechanical inspection of the engine revealed that foreign matter was lodged in the main metering jet of the carburetor. This obstruction prevented the engine from operating at full power, confirming that the loss of thrust was due to internal contamination rather than pilot error or structural failure.
Findings
The primary factor in this accident was the fuel system contamination caused by unidentified foreign matter in the carburetor. The pilot's decision to attempt a landing on runway 27 was reasonable given the circumstances, but the overrun resulted in substantial damage and the aircraft flipping over. No injuries were reported, but the event highlights the critical need for regular fuel system maintenance and filtration checks.
Safety message
Pilots should be aware that foreign object debris can cause sudden engine failure. Regular pre-flight inspections and adherence to maintenance schedules are essential to prevent such occurrences. Additionally, pilots must always consider the available runway length and terrain when planning emergency landings.
