Probable cause

The pilot in command inadvertently stalling the aircraft. Factors were the pilot not maintaining proper altitude during the approach and his abrupt aircraft handling.

Analysis

The glider pilot reported not finding lift several miles to the west of the airstrip. Upon reaching 1,500 feet AGL and descending, he elected to proceed toward the airfield located to the east of his position. He established 55 knots of airspeed and descended to approximately thirty feet above the trees. After clearing the trees he made an aggressive right banking turn to align with runway 17. During the roll out the glider stalled. The right wing struck the grass terrain followed by the fuselage. The pilot stated that he made a mistake by getting too low and slow and banking too steeply during the turn while landing.
