The pilot was conducting an aerial observation of powerlines with three passengers onboard. The pilot stated he was heading westbound checking a cross arm at a slow hover. He then began to accelerate and turned east about 100 feet above the ground when a gust of wind pushed against the helicopter and the helicopter began to rotate to the right. The pilot attempted to accelerate into the wind to no avail and the aircraft 'corkscrewed' down into the ground. On the ground, the helicopter rolled on to its right side. Winds were reported out of the west at 280 degrees at 16 knots gusting to 22 knots 15 miles east of the accident site. No pre-impact deficiencies were reported with the engine or airframe.
