What happened
During an aerial spraying flight, the aircraft struck at least three power lines while maneuvering for a spray pass. The impact severed two of the lines and caused fraying to a third. Following the collision with the wires, the plane struck the ground with its left wing low and came to rest in an inverted position.
A post-accident fire destroyed the wreckage. Witnesses at the scene were able to pull the unconscious pilot from the burning aircraft.
Findings
The pilot reported that the aircraft started under a wire but could remember no further details of the event. An examination of the pilot's medical records revealed a vision waiver that required the use of corrective lenses. However, investigators found no evidence to suggest that the pilot was wearing corrective lenses during the flight.
