Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

After about 1.5 hours of ridgeline flying, and during the outbound leg from the departure airport, the glider approached a valley. According to the pilot, "the ridge lift in this area dissipated rapidly due to a shift in wind direction." Due to the loss in lift, the pilot circled over a field and set up a downwind, base, and final approach for a landing. While on the "short final" leg of the approach, the pilot noticed an obstacle, elected to climb over it, and to land as quickly as possible on the opposite side. During the rollout, the pilot attempted to maneuver the glider between two trees; however, both wingtips impacted the trees, and the glider was substantially damaged.

NTSB Probable Cause Narrative

A loss of lift, which resulted in a forced landing.
