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 was landing on a gravel runway as part of an organized fly-in event. During the landing roll, an all-terrain vehicle (ATV) entered and proceeded down the runway, weaving from side to side. To avoid the ATV, the pilot pulled back on the control yoke. The airplane climbed and then drifted to the left, striking a tree on the edge of the runway; the airplane then turned left 180 degrees and came to rest in the brush alongside the runway. The airplane sustained substantial damage to the right aileron. The pilot noted that the accident might have been avoided if the organization that hosted the event had taken responsibility for securing the runway.

Full Narrative
The pilot was landing on a gravel runway as part of a organized fly-in event. During the landing roll an all-terrain vehicle (ATV) entered, and proceeded down the runway weaving from side-to-side. In an attempt to avoid the ATV he pulled back on the control yoke, and climbed the airplane over the ATV. The airplane drifted to the left, and struck a tree on the edge of the runway; it then turned left 180 degrees, and came to rest in the brush alongside the runway. The airplane sustained substantial damage to the right aileron. In the pilot’s written statement to the National Transportation Safety Board he noted that the accident might have been avoided if organizations which host these type of events took responsibility for securing the runway.
