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 student pilot of the glider, another glider was still on the runway as he was entering the downwind leg of the airport traffic pattern for landing. He decided to land short of the turf runway and entered the glider into a forward slip in order to touch down in the intended area. He reported that, upon removing the slip, he noted that the airspeed decayed “from 60 to 30,” and about 40 to 45 ft above the ground, he realized that the glider was “stalled” and that he “had no control over the aircraft.” The glider impacted a parked tow airplane and terrain, resulting in substantial damage to the leading edge of the left wing and the aft fuselage. The student pilot reported no preimpact mechanical malfunctions or failures with the glider that would have precluded normal operation.
NTSB Probable Cause
The student pilot’s failure to maintain airspeed during the landing approach, which resulted in an exceedance of the glider’s critical angle of attack, an aerodynamic stall, and a loss of control.
