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 a powered glider reported that, after the engine had been shut down and the propeller stowed, he encountered more downdrafts?than expected. The glider did not have sufficient altitude to reach the airport or to re-deploy the engine. During the forced landing on rough terrain, a wing impacted vegetation and ground looped, resulting in substantial damage to the fuselage and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the powered glider that would have precluded normal operation.
