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.

ANC22LA042
The pilot of a twin-engine, turbine-powered airplane was landing at a remote, rough, soft, turf and grass covered airstrip at the completion of a Part 135 cargo flight. He said that after an uneventful touchdown, as the airplane’s landing roll slowed, the right main landing gear wheel and the nose wheel contacted an area of soft, muddy terrain. The airplane’s nose wheel collapsed, and it subsequently folded under the fuselage. The airplane sustained substantial damage to the fuselage. The pilot reported no mechanical problems that would have precluded normal operations.
NTSB Probable Cause
The pilot’s selection of an unsuitable landing site, which resulted in the nosewheel collapsing.
