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 airplane sustained substantial damage to the right wing. The pilot reported that there were no pre-accident mechanical malfunctions or failures with the airplane. He further reported about 14,000 hours of total flight experience, which included 4,700 hours in the same make and model as the accident airplane.
