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.

According to the pilot, during the landing, a gust of wind pushed the airplane to the right of runway centerline. The pilot applied rudder and aileron inputs to counter the unexpected wind. Subsequently, the airplane ground looped and came to rest upright on the runway. A postaccident examination of the airplane revealed the right wing spar was bent. No airframe or engine anomalies were reported by the pilot. The wind conditions at the airport were light and variable at the time of the accident.
