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.

ANC09CA070
The commercial pilot reported he was practicing touch-and-go landings in his homebuilt, tailwheel-equipped airplane at an off airport site, which required a correction for a variable left crosswind. The airplane was operated under Title 14, Code of Federal Regulations Part 91 personal flight. The pilot said that during touchdown on the mud-covered site, a gust of wind pushed the airplane to the right, and it subsequently ground-looped to the left. The right main landing gear collapsed, and the right wing struck the ground. The airplane sustained substantial damage to the right wing and fuselage. The pilot indicated that there were no preaccident mechanical problems with the airplane, and noted in his report to the NTSB that the accident could have been avoided if he had been proficient in crosswind landings at off airport sites.
NTSB Probable Cause
The pilot's failure to maintain directional control during the landing roll, resulting in a ground-loop and substantial damage to the airplane.
