NTSB Narrative Summary Released at Completion of Accident

The pilot had completed his first spray pass of the flight and was maneuvering for another pass when the airplane experienced a loss of engine power. The pilot attempted a restart; however, it was unsuccessful. He elected to perform a forced landing to a corn field. During the forced landing, the airplane sustained substantial damage to the wings and empennage. Examination of the airframe, disassembly of the engine, and functional testing of the engine components showed no anomalies that precluded normal operation. The reason for the loss of engine power was not determined.

NTSB Probable Cause Narrative

A loss of engine power for undetermined reasons.
