The NTSB's narrative final · quoted from the NTSB record
The private pilot reported that the purpose of the flight was to apply pesticides to a field. The takeoff and transit to the work area were normal; however, after he had conducted a few spray runs, the engine power began to degrade. The pilot decided to fly the airplane back to the airport. The engine power continued to degrade, so the pilot moved the fuel boost pump switch to the "on" position; however, the engine then lost total power, and the pilot was forced to land the airplane in a cornfield about 3 miles from the airport. During the forced landing, the left main landing gear collapsed, and the airplane ground looped, which resulted in substantial damage to the fuselage and wings. A postaccident examination of the fuel system and the engine revealed no anomalies.
