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 reported that he was practicing touch-and-go landings on runway 36. While on his third approach after making two landings, he noticed that the windsock was now favoring runway 18 and that the wind was gusting. He performed a go-around and made an approach to runway 18. After a conventional (tailwheel) landing, the airplane’s left wing started to rise and the tail swung to the right. The pilot applied left rudder, but the tail continued to the right. The right main gear buckled and the right wing struck the runway. The wing was crushed from the strut to the tip. The pilot did not report any preaccident malfunctions or failures with the airplane that would have precluded normal operation.
