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.

The pilot of the glider reported that, while in thermal flight, he made a turn to the south to follow a ridgeline. Before he reached the top of the mountain, the glider experienced a loss of lift. To compensate, he maneuvered the glider away from terrain and encountered additional sink. While maneuvering the glider toward lower terrain, the right-wing tip struck a tree. The glider struck additional trees before it impacted terrain and came to rest between two trees. The glider sustained substantial damage to the right wing and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
NTSB Probable Cause
The gliders encounter with atmospheric conditions where the lift was not sufficient to maintain flight and subsequent impact with mountainous terrain.
