Accident Sequence
During the initial climb phase, the aircraft suffered a total loss of engine power. The pilot maneuvered the aircraft in a turn toward an emergency landing area. During this turn, the aircraft stalled and entered an aerodynamic spin, subsequently impacting the terrain.
Post-Accident Examination
A subsequent investigation examined the aircraft's engine and carburetor. Investigators found a foreign substance blocking the main metering orifice within the carburetor. The substance was determined to have migrated from a missing gasket on the carburetor's drain plug.
Maintenance Details
The pilot reported that he had used a substitute material to replace the missing gasket on the drain plug. The investigation concluded that the foreign substance originated from this substitute material, which then obstructed the carburetor's main metering orifice, leading to the loss of engine power.
Conclusion
The investigation did not identify any other contributing factors. The event was directly linked to the presence of the foreign substance in the carburetor, which caused a total power loss during a critical phase of flight.
