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.

NTSB Number
WPR20CA168
The pilot of the tailwheel-equipped airplane reported that, during the landing roll, the airplane veered to the left, and he elected to abort the landing. The pilot applied full power and the airplane momentarily became airborne but shortly thereafter, it settled back onto the runway and ground looped to the left. The airplane exited the runway surface and nosed over. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to maintain directional control of the airplane during an aborted landing, which resulted in a ground loop, runway excursion, and subsequent nose over.
