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, during the takeoff roll on a dirt airstrip, the tailwheel-equipped airplane veered to the right. He added that he "could not see [the] right edge of [the] strip due to [the] tail being low and [the] contour of [the] terrain descending away"; therefore, "corrective measures were not applied." Subsequently, the airplane veered off the right side of the runway, impacted small shrubs/trees and a large rock, and then came to rest inverted. The airplane sustained substantial damage to both wings and the empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
