Overview
A glider accident occurred during landing when the pilot executed an approach with flaps, a configuration he was not familiar with. This led to a misjudged approach and a landing that was longer than intended.
Pilot Statement
The pilot reported that he made his approach to the landing area with flaps, a configuration with which he was not very familiar. As a result, he misjudged the approach and landed long.
Landing Conditions
The landing strip was described as hilly with rough and uneven terrain. Recent rains had made the surface soft in spots, further complicating the landing.
Sequence of Events
During the landing roll, the pilot encountered a sharp bump, which was followed by a sideways motion. The left wing then went down, and the glider ground looped.
The accident sequence ended with the glider ground looping after the left wing dropped. The pilot's unfamiliarity with the flap configuration contributed to the misjudged approach and subsequent long landing on the challenging terrain.
