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.

DCA17CA147
On June 30, 2017 at 2130 central daylight time, the wingtip ("sharklet") of an Airbus A321, N991AU, operated by American Airlines flight 1162, contacted the horizontal stabilizer of a Bombardier CRJ200, N862AS, operated by SkyWest Airlines d.b.a. Eagle Flight 3047, during taxi at the Chicago O'Hare International Airport. The A321 received minor damage and the CRJ200 was substantially damaged. There were no injuries aboard either aircraft. The CRJ200 had landed and taxied to the terminal and had been instructed by air traffic control to follow another aircraft on taxiway A7. Another aircraft ahead stopped unexpectedly and the line of traffic ending with the CRJ200, had to stop. The A321 was taxiing along taxiway A, perpendicular to A7, and maneuvered to go around the protruding tail of the CRJ200. However, the left sharklet wingtip of the A321 contacted the horizontal stabilizer of the CRJ200.
NTSB Probable Cause
the A321 flight crew's incorrect evaluation of the clearance between the aircraft, leading to the inadvertent collision with the horizontal stabilizer of the CRJ200. Contributing to the accident was traffic congestion that resulted in the CRJ200 having to stop prior to fully clearing the perpendicular taxiway.
