SCHWEIZER SGS-2-33A

Full Narrative

The student glider pilot had flown in the morning, and returned for a flight to gain experience in afternoon wind conditions. This was his eighth solo flight, and his launch limitations were surface winds less than 10 miles per hour (mph) and crosswinds no greater than 60 degrees to the runway. Takeoff conditions met those parameters, and he departed. He returned for landing, and was maintaining 60 mph at 700-800 feet above ground level (agl). He felt that this was high towards the end of the downwind leg for runway 19, and he performed a slip maneuver to lose altitude to 500-600 feet. When he turned to the base leg, the glider suddenly lost altitude to about 300 feet agl, and he initiated an early turn to final.

The student's certified flight instructor (CFI) reported that, when the student turned from downwind to base, the glider was lower than expected, and he observed the spoilers open. As the CFI was about to radio the student, the spoilers closed. The CFI stated that the glider was low, slow, and nose high as it approached the runway threshold. It appeared to stall, and dropped onto the runway from an altitude of 5-6 feet. It hit hard, bounced, and dragged both wing tips. After the glider came to a rest, the CFI reported that the spoiler's were not out.

A witness stated that the winds had been from the south-southwest at 10 knots most of the day with occasional gusts greater than 10 knots. Twenty minutes prior to the accident, the wind was reported from 270 degrees at 16 knots.
