The NTSB's narrative final · quoted from the NTSB record
The pilot reported that the engine lost power during the middle of a spray run when he was just above the height of the corn crop. He turned the airplane away from the town and power lines before it contacted small trees and a ditch during the forced landing in a bean field. Both wings were substantially damaged. A teardown of the engine and a functional check of the fuel control unit, high pressure fuel pump, and the propeller governor failed to reveal any failures that would have prevented the engine from producing power.
