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.

During a landing, the glider collided with high vegetation on the left side of the runway after the student pilot allowed it to touchdown left of the runway centerline. The left wing tip dragged in the vegetation, and the glider ground looped to the left. The instructor stated that he was overconfident in the student's ability and did not anticipate his actions. The runway was 4,000 feet long and 75 feet wide. The wing span of the glider was about 57 feet.

NTSB Probable Cause

failure of the student pilot to maintain proper runway alignment and wing tip clearance from high vegetation beside the runway during landing, and the flight instructor's inadequate supervision of the flight. High vegetation on the runway shoulder was a related factor.
