NTSB Narrative Summary Released at Completion of Accident

The agricultural spray airplane was destroyed by post impact fire after it hit a power line and impacted the terrain. The pilot reported that he had sprayed one cornfield and was starting to spray another 20-acre cornfield. He reported that he flew over the field and observed power lines.
