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, he was conducting his fourth solo flight and during the aero tow he "ballooned" and drifted to the right. The pilot repositioned the glider, slack developed in the tow rope, and the rope disconnected from the glider approximately 10 feet above the ground. The pilot did not use the dive brake to descend and landed long, resulting in substantial damage. An examination of the glider systems, conducted by the FAA, revealed no anomalies.
