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.

NTSB Number
WPR25LA144
The glider pilot was on a local flight and returning to a local airport to land. While the pilot maneuvered the airplane onto the final approach leg of the traffic pattern, the airplane descended. Subsequently, the right wing dropped and impacted the ground 0.5 miles short of the runway. The right wing sustained substantial damage. The pilot reported to the insurance company that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot did not submit the National Transportation Safety Board Pilot/Operator Aircraft Accident/Incident Report Form 6120.1.
NTSB Probable Cause
The pilot's exceedance of the airplane's critical angle of attack during the final approach to land, which resulted in an aerodynamic stall and impact with terrain.
