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.

ERA21LA385
The pilot reported that after landing, he applied the brakes and felt a “violent shimmy.” He released the brakes and the nose landing gear leg rotated left and aft which resulted in the right wing impacting the runway surface. A post-accident examination revealed that the nose landing gear retention bolt had sheared and the airplane had sustained substantial damage to the right wing. The pilot stated that he was the second owner and noticed that the original builder had not followed the design plans for the airplane, so the pilot modified the nose wheel attach plate to strengthen it but did not modify the gear assembly attach point which resulted in the failure.
NTSB Probable Cause
The failure of the nose landing gear retention bolt during taxi which resulted in a loss of control and subsequent impact with the taxiway.
