The pilot was spraying a field when the upper left wing struck a telephone line, which was strung under a set of power lines. The aircraft tumbled to the ground and caught fire on impact, coming to rest about 300 feet from where the wires were hit. Two leading edge pieces from the upper left wing were torn from the aircraft and found approximately 60 feet from where the wires were hit. The pilot's son reported that his father knew the telephone line was strung on the west side of the field, but stated that his father just forgot that the telephone line and cable were strung below the power lines. No preimpact mechanical failures were found during an examination of the wreckage.
Probable Cause: The failure of the pilot to maintain an adequate clearance with the telephone wires.
