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.

According to the pilot, after he landed, he taxied the airplane to the top of the hill to pick up a load he was going to transport and then past it to turn the airplane around. He turned the airplane slowly to maintain control, and then taxied down the hill back to the load and noted the wind was now a tailwind. The pilot applied the brakes to stop the airplane, but the wind lifted the tail, and the airplane nosed over, resulting in substantial damage to the rudder and wings. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain airplane control during taxi in gusty conditions, which resulted in a nose-over and substantial damage to the rudder and wings.
