What happened
The aircraft was engaged in a local area flight that lasted approximately 20 minutes after takeoff. The pilot decided to return to the airport for landing. During the approach phase, the engine began to lose power, which quickly progressed to a complete loss of power. Unable to maintain altitude or reach the runway, the pilot conducted a forced landing in a field located approximately one quarter mile from the approach end of the runway.
The investigation
Following the accident, an inspection of the aircraft was conducted to determine the mechanical cause of the engine failure. The examination revealed the presence of debris within the carburetor filter. This obstruction likely restricted fuel flow or airflow, leading to the power loss experienced by the pilot during the critical approach phase.
Findings
The forced landing resulted in significant damage to the aircraft. During the landing roll on the soft field surface, the aircraft nosed over. The investigation confirmed that mechanical failure due to contamination was the primary factor. The debris found in the carburetor filter indicates a maintenance or inspection oversight allowed foreign object debris to enter the engine system.
Safety message
Regular inspection and cleaning of fuel system components, including carburetor filters, are essential to prevent ingestion of debris that can cause engine failure. Pilots should also be aware of the risks associated with landing on soft or uneven terrain during emergency situations.
