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
GAA17CA204
The pilot of the tailwheel-equipped airplane reported that, during landing on a backcountry dirt airstrip in a crosswind, the airplane touched down and bounced. He added that he attempted to maintain directional control, but a "[wind] gust weathervaned the aircraft nose left," and the right main landing gear wheel dug into the ground during the second touchdown. Subsequently, the airplane ground looped to the left, and the right wing impacted the ground. The airplane sustained substantial damage to the right 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 improper compensation for crosswind conditions during the landing flare and his subsequent failure to maintain directional control during the landing.
