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
GAA17CA399
The pilot of the tailwheel-equipped airplane reported that, during the landing roll, the tailwheel shimmied, so he held full aft elevator input until the airplane slowed. He then "slightly" released the back pressure when the airplane suddenly swerved to the right. The pilot was unable to correct the turn, and the airplane ground looped. The left main landing gear collapsed, and the left wing impacted the ground. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
