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.

SEA08CA148
The pilot performed a wheel landing in a tailwheel-equipped airplane with variable wind conditions present. During the landing roll, the tail of the airplane began to settle as the airplane veered suddenly to the right. The pilot's efforts to correct the veer were unsuccessful and the airplane ground looped. Examination of the airplane revealed that the left main landing gear was underneath the fuselage and the outboard portion of the left wing was structurally damaged. The pilot stated there was no mechanical anomalies with the engine or flight control system at the time of the accident.
NTSB Probable Cause
The pilot's failure to maintain directional control during landing. A contributing factor was the variable wind condition.
