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, she did not perform a flight control check prior to takeoff. During the departure roll, when the airplane reached 70 miles per hour, she realized that the gust lock was still installed in the control column. She attempted to remove the device, but was unsuccessful. She reduced the engine power in an attempt to stop the airplane, but it continued off the end of the runway; the nose gear separated, and it came to rest in a dirt field. The airplane sustained substantial damage to the firewall and right wing.
