Probable cause

Failure of the pilot-in-command to maintain control of the aircraft while conducting aerial application maneuvers in close proximity to the terrain.

Analysis

During an aerial application maneuver, the aircraft departed controlled flight and impacted the terrain. The aircraft was destroyed and the pilot sustained fatal injuries. Subsequent investigation found nothing of a mechanical nature in the wreckage that would have contributed to the accident.
