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.

NTSB Number
ANC14CA080
The pilot was landing in a tailwheel-equipped airplane at a remote, rough and uneven off-airport site, which required a correction for a 15 to 20 mph left crosswind. He stated that during the landing roll the wind pushed the airplane to the left, which resulted in a side load on the main landing gear, and the right main landing gear wheel axle separated. The right wing subsequently struck the ground, sustaining substantial damage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's inability to maintain directional control of the airplane resulting in a separation of the wheel axle, resulting in a collision with terrain.
