NTSB Narrative Summary Released at Completion of Accident

In a written statement, the student pilot reported that he was landing his glider, a LET Blanik L-13, on 25L, while another glider, a DG 505 was positioned on 25R approximately 1000 feet from the departure end of the runway. The DG 505 was hooked to a tow plane and waiting for takeoff on runway 25R. The Blanik L-13 made a normal landing on runway 25L with a touchdown point 500 feet from the end of the runway. During the landing roll, the glider veered to the right and collided with the DG 505 before coming to a stop. The right wing of the Blanik L-13 impacted the left wingtip of the DG 505. The flight instructor in the DG 505 stated in a written report: "there was ample room (for landing), but the pilot made the mistake of looking at the obstruction (me), rather than ahead up the runway." A post accident inspection revealed substantial damage to the Blanik L-13, including distorted wing skins, detached wing attachments and bent bulkheads in the fuselage. The minor damage to the DG 505 was contained to a detachable wing tip.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control during landing roll.
