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 reported that on the takeoff roll, he detected a vibration that he initially attributed to nosewheel shimmy. The vibration became extreme within a few seconds, and the pilot attempted to abort the takeoff by reducing the engine throttles. During the deceleration, the airplane went to the right which the pilot was unable to correct using differential braking. The airplane went off of the paved runway surface and the nose landing gear collapsed forward. Postaccident inspection revealed that the nose landing gear upper retract link assembly had fractured which allowed the nose landing gear to partially collapse in the forward direction. The engine propellers contacted the ground during the event and the airplane sustained substantial damage to the fuselage.
