Narrative:
After flying for about 1 hour, the student pilot hovered 2 feet above ground level about 50 yards away from a witness. The local wind speed had varied between calm and 5 knots during the flight. The witness and pilot reported that suddenly an estimated 25 knot (maximum) wind gust developed. The gust pushed the helicopter sideways, the pilot lost control, a skid contacted the ground, and the helicopter rolled over onto its side.
Probable Cause: The sudden development of a wind gust which resulted in the pilot losing control, and the helicopter's dynamic rollover when a skid contacted the ground.
