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.

While landing at a 1,000-foot-long remote dirt airstrip, the pilot encountered gusting variable winds. He said that while focusing on compensating for those winds, he failed to slow the airplane sufficiently. After touchdown, the airplane ran off the end of the airstrip, encountered rocks, and nosed over onto its back.
NTSB Probable Cause
The pilot's inadequate short-field landing procedure and excessive airspeed that resulted in a landing overrun. Contributing to the accident were gusting unfavorable winds, the short runway, and rocks off the departure end of the strip.
Full Narrative
During the landing roll at a 1,000 foot long remote dirt airstrip, the pilot encountered gusting winds that varied in the their direction. While focused on compensating for the unfavorable winds, the pilot failed to slow the airplane sufficiently to ensure that it could be stopped prior to reaching the end of the airstrip. The airplane therefore overran the end of the airstrip, impacted a number of large rocks, and flipped over onto its back. The accident sequence resulted in damage to the top of the vertical stabilizer, and a permanent bend in both of the lift struts on the left side of the airplane.
