Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

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