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 of the tundra-tire-equipped airplane reported that, while departing from a remote gravel bar, he heard a "clunk" just after takeoff. While en route to his destination airport, he noticed that the right main landing gear assembly had partially separated from the airplane. During the subsequent landing roll, the right main landing gear collapsed and the right wing struck the ground, sustaining substantial damage. The pilot's postaccident inspection revealed a separated oleo shock absorber strut. He noted that, other than the separated main landing gear oleo strut, there were no preaccident mechanical anomalies with the airplane.
NTSB Probable Cause
The separation of the right main landing gear oleo strut assembly, resulting in the collapse of the main landing gear during the landing roll.
