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 reported that during landing, a gust of wind displaced the glider laterally to the left. She attempted to maneuver for a normal landing on the grass runway; however, the glider was too low to maneuver around a parked glider. She landed at an angle on the runway, and the glider ground looped and sustained substantial damage to the fuselage and wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation. At the time of the accident, the pilot was landing the glider on runway 25 with wind from 260° at 12 knots, gusting to 17 knots.
