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 in the tailwheel-equipped airplane, he landed on tundra that had an uphill slope. Before touchdown, the pilot shut off the engine "in case of a nose over event." He reported that, after the landing roll, when the airplane was completely stopped on level ground, a tailwind gust lifted the tail. The airplane balanced on the nose for about 10 seconds, a second gust pushed the airplane over, and it came to rest inverted. The airplane sustained substantial damage to the rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s inability to maintain pitch control due to an encounter with a tailwind gust after the airplane had stopped, which resulted in a nose-over.
