The NTSB's narrative final · quoted from the NTSB record
According to the pilot, he refilled his restricted category helicopter with 80 gallons of defoliant and proceeded to take off from a farm field adjacent to a country road. He had made two previous departures from the same location and was aware of nearby power lines. During the climb over the power lines, the pilot allowed the engine, rotor rpm, and airspeed to decrease. The pilot further indicated that he attempted to regain airspeed and rpm by lowering the nose of the helicopter. His efforts were not successful, and the helicopter made a hard touchdown in the field.
