Location: Chicago, IL
Accident Number: DCA17CA147A
Date & Time: 06/30/2017, 2130 CDT
Registration: N991AU
Aircraft: AIRBUS A321 231
Aircraft Damage: Minor
Defining Event: Ground collision
Injuries: N/A
Flight Conducted Under: Part 121: Air Carrier - Scheduled
Analysis
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 CRJ700, N862AS, operated by SkyWest Airlines d.b.a. Eagle Flight 3407, during taxi at the Chicago O'Hare International Airport. The A321 received minor damage and the CRJ700 was substantially damaged. There were no injuries aboard either aircraft. The CRJ700 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 CRJ700, had to stop. The A321 was taxiing along taxiway A, perpendicular to A7, and maneuvered to go around the protruding tail of the CRJ700. However, the left sharklet wingtip of the A321 contacted the horizontal stabilizer of the CRJ700.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
the A321 flight crew's incorrect evaluation of the clearance between the aircraft, leading to the inadvertent collision with the horizontal stabilizer of the CRJ700. Contributing to the accident was traffic congestion that resulted in the CRJ700 having to stop prior to fully clearing the perpendicular taxiway.

Incorrect action performance - Flight crew (Cause)
