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 the glider reported that while on downwind, the tow airplane maneuvered to avoid another aircraft, which resulted in a slack tow line. The tow line subsequently broke, and the glider pilot initiated a landing to a nearby runway from about 900 ft above ground level (agl). During the landing roll, the glider drifted right, and the right wing impacted a taxiway sign, which resulted in substantial damage to the wing spar. The pilot reported that there were no preaccident mechanical malfunctions or failures with the glider that would have precluded normal operation.

NTSB Probable Cause

The pilot’s failure to maintain directional control during the landing roll, resulting in an impact with a taxiway sign.
