Confidence Rating: Accident investigation report completed and information captured
The pilot was competing in an open class national soaring contest, and strong surface wind conditions were present. Locally, the wind speed was at 20 knots, with gusts to 30 knots. At the conclusion of his flight, the pilot turned onto the final approach leg with extra airspeed. When the glider had descended between 5 and 10 feet above the ground, a wind gust lifted its right wing upward, and the left wing contacted the ground. The pilot lost control, and the glider cartwheeled and nosed over.

Probable Cause: A loss of control during landing flare. Contributing to the accident was the gusty wind condition.
