Analysis

Several witnesses reported that the purpose of the flight was blackbird control of a sunflower field. There was speculation by local residents that the aircraft was being used to spread poisoned corn. This was substantiated when corn and a portion of an avitrol bag were found later at the crash site. During the flight, the aircraft was observed flying at low altitude, then pulled up over a row of trees north of the accident site. It then proceeded south toward the town of Oakes, ND and made a steep turn in the vicinity of the pilot's home. Witnesses stated that the aircraft was just above the rooftops and seemed to settle and collide with a house. After impact, the aircraft burst into flame. The aircraft and a portion of the house were destroyed by impact and fire.
