Accident Description
The aircraft was conducting a planned agricultural flight. During the takeoff roll, it departed the runway at its departure end. After leaving the runway, it continued through a field of uncut wheat. Eventually, the aircraft encountered a shallow washout and a small bank, which caused it to flip over. There were no known witnesses to the accident.
Examination Findings
Following the accident, an investigation revealed that fuel was present in the aircraft's fuel tanks. The magneto and battery switches were in the on position. The throttle was found at approximately one-quarter open, the mixture was set to rich, and the propeller control was full forward. One propeller blade was bent underneath the engine and had light scratches running parallel to its front surface. The other two propeller blades were intact, unbent, and showed no scratches. Wheat straw was found on the main landing gear struts and the tailwheel spring.
Engine Inspection
A teardown inspection of the engine identified a discrepancy with the right magneto: its points were dwelled closed and failed to open. The points exhibited burning and corrosion. No other anomalies were discovered during the teardown.
