| Confidence Rating: |  Accident investigation report completed and information captured |
As the student pilot began his landing flare approximately 10 feet above the runway surface, he observed a dust devil move onto the runway directly in front of him. He applied down elevator control but the glider ascended about 50 feet above the ground into the dust devil. The glider stalled and landed hard on the runway, then ground looped. Ground witnesses observed a 'large and violent dust devil' touching down on the runway in the path of the landing glider just as it was in the landing flare.
Probable Cause: The pilot's encounter with a sudden and violent dust devil, which caused the student pilot to lose control of the aircraft during the landing flare/touchdown.
