NTSB Narrative Summary Released at Completion of Accident

The pilot stated he had topped off the accident airplane's fuel before departure. He said that during the landing approach, he reduced engine power, lowered the landing gear, and extended 1/2 flaps. Subsequently, he applied power and the engine did not respond. A soybean field was selected and a forced landing executed in the field resulting in substantial damage. The investigation revealed engine continuity and no pre-existing engine anomalies were found. Fuel was recovered from the airplane. Fuel was also present on the ground at the scene and the glass gascolator bowl was found broken. The fuel selector was found on the main tank position and was selected to the off position by the first person to arrive at the accident site.

NTSB Probable Cause Narrative

Loss of engine power for undetermined reasons.
