The 5,740-hour commercial pilot lost control of the single-engine helicopter while maneuvering during an aerial application flight. The pilot stated, that he made a right turn into the wind and that a gust of wind "must have hit the tail causing him to lose tail-rotor authority." The pilot further stated that he corrected with full left pedal; however, the helicopter touched down and the left skid dug into the soft ground causing the aircraft to roll onto the left side. At the time of the accident, the wind was reported from 240 degrees at 4 knots, gusting to 12 knots. The pilot reported having accumulated 70 hours in the same make and model.
