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 glider pilot reported that, while maneuvering about 10,000 ft mean sea level he "lost control," and the glider went into a spin, followed by a spiral. He added that he egressed from the glider, deployed his parachute, and was later rescued. The glider impacted terrain and was destroyed. 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 pilot’s failure to maintain the proper airspeed and his exceedance of the glider’s critical angle of attack, which resulted in a stall/spin.
