NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that the airplane's engine lost power and began shaking violently as the airplane was approximately mid-field downwind for landing. He stated that he had insufficient altitude to execute a power-off landing to the runway and elected to land the airplane in a farm field. He said that he flared the airplane and as the airplane settled into the corn, he applied full aft elevator but the airplane pitched nose down and flipped onto its back. He stated that he had performed a pre-flight engine run-up before the accident. He made no mention of any discrepancies noted during the run-up, takeoff, or initial climb out.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The loss of engine power for an undetermined reason and the unsuitable terrain encountered during the forced landing. The corn crop was a factor.
