What happened
During an aerial application mission involving crop spraying, a single-engine airplane was operating at a low altitude. While performing maneuvers necessary for the spraying task, the aircraft experienced an aerodynamic stall. This loss of lift caused the plane to descend rapidly into a field.
As a result of the impact, the captain sustained fatal injuries. The copilot survived the crash but suffered serious injuries during the event.
Findings
Official investigations into the accident concluded that the precise reason for the stall and subsequent crash could not be determined.
