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 the tailwheel equipped airplane reported that during the landing roll, as the airplane slowed down, the tailwheel lifted off the ground. He further reported that the airplane veered to the right despite left rudder and brake application, exited the runway, and ground looped. According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The airplane sustained substantial damage to the fuselage and empennage.
NTSB Probable Cause
The pilot's failure to maintain directional control during the landing roll, which resulted in runway excursion, and a ground loop.
