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 tailwheel-equipped airplane reported that, during landing on a gravel airstrip, when the right main wheel touched down, the airplane veered right. He applied full left rudder to no avail. The right wheel exited the runway into soft, sandy soil, and the airplane nosed over. The airplane sustained substantial damage to the wings and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot added that, after the accident, it was pointed out that the airplane had a flat tire and that there was a tire mark on the gravel runway from where the airplane touched down to where the airplane nosed over.
