Analysis

The pilot reported that after takeoff he flew to an area of thermal activity. Upon completing several minutes of upper air work, the pilot elected to return to the departure airport. While en route to the departure airport, the pilot realized that he had entered an area where he was unable to maintain altitude and thermal activity was lost. The pilot selected a nearby bean field for an emergency landing. According to the pilot, during the landing roll, the right wing collided with a tall plant and the glider ground looped. Examination of the glider at the accident site revealed structural damage to the fuselage aft section. No mechanical problem was reported by the pilot.
