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 upon entering the airport traffic pattern, he remained at a higher altitude than normal on the downwind and base legs due to helicopter traffic. Upon turning onto the final leg, the approach angle to the runway was steeper than normal and the airplane was still high. He stated that due to the steeper approach angle, he misjudged the landing flare; the airplane landed hard, bounced, and began to porpoise. As the pilot attempted to abort the landing, the airplane veered to the right and landed in the dirt adjacent to the runway where the airplane nosed over and sustained structural damage to both wings, the vertical stabilizer, and the rudder. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
