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 student pilot reported that during landing the glider touched down slightly left of the runway centerline. He engaged the brakes and steered the glider towards the right side of the runway to prepare for a turn. When he approached the taxiway entrance, he released the brakes and started to turn to the left. During the turn the left wing struck a runway sign; the airplane made a sharp left turn, exited the runway surface and came to rest on the grass. During the accident sequence, the left wing sustained substantial damage. The pilot reported no mechanical malfunctions or failures with the airframe that would have precluded normal operation.
