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.

As the glider pilot crossed the runway threshold for landing, he realized that he was too high, and instead of further extending the airbrakes, which at the time were between one-third and one-half deployed, he lowered the nose of the aircraft in order to descend. This action increased the airspeed by about seven knots, and resulted in the aircraft landing about half way down the 2,100 foot runway. During his attempt to stop the aircraft on the remaining runway, the pilot inadvertently let the aircraft depart the left side of the runway, and as he attempted to get the aircraft back onto the runway surface prior to reaching the emergency run-out area, the aircraft came in contact with the side-slope of the built-up run-out area terrain.
NTSB Probable Cause
The glider pilot's failure to maintain directional control during the landing roll, resulting in the aircraft impacting the dirt embankment on the side of the emergency run-out area. Factors include the pilot's improper decision not to deploy more airbrakes when he realized that he was crossing the threshold at too high of an altitude, and his failure to attain the proper touchdown point during the landing flare.
