Fast key and full-text search with live filters, watches, and precise metadata.
Use quotes for exact phrase matches (for example "fuel selector valve").
Track fatal and non-fatal accident patterns across Part 91, Part 135, and Part 121 operations.

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.
Kingman, AZ
The pilot reported that 1-2 seconds after landing on runway 21, he heard a 'bang', then the right wing dropped, and the airplane ground-looped to the right, substantially damaging the wing and fuselage. Upon examination of the right landing gear strut, he observed that the right wheel had separated from the strut leg. Examination of the bolts that attached the wheel to the strut revealed that one bolt fractured and the other two were stripped of their respective nuts. The pilot stated that the bolts installed on the wheel were not in compliance with a recent service bulletin that recommended a higher tensile strength bolt.
