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 in the tailwheel-equipped airplane reported that he landed the airplane on an upsloping, uneven sand bar. During the landing roll, the airplane's nose pivoted to the right, and the left wing and horizontal stabilizer struck the ground. The left-wing spar, the left aileron, and the left side of the vertical stabilizer and elevator sustained substantial damage. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's selection of unsuitable terrain for landing, which resulted in the left wing and horizontal stabilizer striking the ground.
