Aircraft Accident/Incident Report

Alamogordo, New Mexico 88310
Saturday, May 12, 2007 14:15 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was landing on a dirt strip that parallels the main runway. Surface winds were "light." Approximately 25 to 50 feet above the ground, the pilot encountered a "heavy sink" and realized he was probably going to touch down in a ditch perpendicular to the dirt strip. The glider touched down at the far end of the ditch. The right wing dropped and struck a runway marker causing substantial damage to glider. The glider spun around and came to a stop 120 to 150 feet from the marker.

NTSB Probable Cause Narrative

The pilot's inability to control the glider after encountering the downdraft causing the glider to land short of the dirt strip. Factors contributing to the accident were the downdraft and the runway marker.
