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 glider reported that he encountered a "heavy sink" on the downwind leg in the traffic pattern. He immediately made a left steep turn toward the runway, but the left wing impacted terrain during the turn to final. Subsequently, the tail section of fuselage impacted the runway, and the glider came to rest on the runway surface. The fuselage sustained substantial damage. About the time of the accident at an airport 11 nautical miles north of the destination airport, the wind was reported at 210 degrees true at 8 knots, the sky condition was clear, temperature was 27 degrees Celsius (80 degrees Fahrenheit), and dew point was 13 degrees Celsius (55 degrees Fahrenheit). The pilot reported there were no mechanical malfunctions or failures with the glider that would have precluded normal operation.
