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 stated he was landing on a remote, rough and uneven gravel bar in a tailwheel-equipped airplane. During the landing roll, the left wing suddenly dipped, and it subsequently struck the gravel bar, sustaining substantial damage. A postaccident examination revealed that the left main landing gear had separated. Examination of the separated landing gear revealed the fractured areas of the weld at the fuselage attachment point exhibited rounded, reflected features consistent with a lack of fusion. In addition, there were areas that were absent of weld material along the circumferential or peripheral area, consistent with a lack of fusion. According to maintenance records the weld was from a landing gear conversion about 11 years prior to the accident.
NTSB Probable Cause
A failure of the landing gear fitting at the fuselage attachment point to due to a poor weld joint.
