NTSB Factual Report

The pilot stated that after being towed aloft, light winds and light lift existed. He elected to return because he was not flying well, and while turning base to final, the left wing contacted the ground. He further reported that the traffic pattern was entered too low, and the airspeed was not maintained. Additionally, he had not flown the glider in the previous 2 years, and his "Lack of recent flying time is the major factor resulting in poor decisions on landing resulting in major damage to the glider."

NTSB Probable Cause

The failure of the pilot to maintain airspeed while turning base to final resulting in the left wing contacting the ground.
