Probable cause

The pilot's inadvertent stall of the glider.

Sequence of events

Analysis

The certificated commercial pilot, the sole occupant, was participating in a glider competition when the loss of thermal lift necessitated an off airport landing. The pilot overshot his intended landing point on a road and began a maneuvering turn to again line up on the road. During the turn, the pilot stalled the glider about 75 feet above the ground, descending in about a 60 degree nose down attitude and rotating clockwise about its vertical axis. The glider struck the ground, crushing the nose and outboard portion of the right wing. The glider was substantially damaged and the pilot received serious injuries.
