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 of a tailwheel equipped airplane reported that he encountered a crosswind during a wheel landing. During the landing roll, the pilot further reported that the airplane "drifted abruptly to the left" and he added right rudder, but the airplane departed the runway to the left. During the runway excursion, the airplane ground looped to the left and collided with an airport sign, the right main landing gear separated, and the right wing impacted the ground. A postaccident examination revealed substantial damage to right wing. 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 failure to maintain directional control during the landing roll, which resulted in a runway excursion, a ground loop, and a collision with an airport sign.
