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.

According to the pilot, the glider's heading differed about 5 degrees from that of the towplane when the towplane began its takeoff roll. The pilot used rudder to correct the heading, but the glider dragged a wing and yawed 70 degrees to its right. The glider lifted 3 to 5 feet above the runway, the pilot released the tow, the glider touched down in a sideslip, and the resultant side load on the tail landing gear "buckled the tailboom 90 [degrees]." The pilot reported that there were no mechanical deficiencies with the glider that would have prevented normal operation, and that the accident might have been prevented by ensuring alignment of the glider with the towplane prior to the takeoff roll.

Full Narrative
According to the pilot, his glider's heading differed about 5 degrees from that of the towplane, when the towplane began its takeoff roll. The pilot used rudder to correct but the glider dragged a wing, and yawed 70 degrees to its right as a result. The glider lifted 3 to 5 feet above the runway, the pilot released the tow, the glider touched down in a sideslip, and the resultant side load on the tail landing gear "buckled the tailboom 90 [degrees]." The pilot reported that there were no mechanical deficiencies with the glider that would have prevented normal operation, and that the accident might have been prevented by ensuring alignment of the glider with the towplane prior to the takeoff roll.
