NTSB Narrative Summary Released at Completion of Accident

While maneuvering during an aerial application of chemicals on a field, the 5,972-hour pilot reported that the left wing collided with the lower set of transmission wires running perpendicular to the field being sprayed, about 60 feet off the ground. The pilot added that he had flown under the same set of wires six or seven times earlier that morning; however, during the last pass, he felt that "the aircraft ballooned and the tail came up." Subsequently, the airplane impacted terrain and came to rest upright.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance from the high tension power lines.
