Factual narrative
On December 8, 2011, Delta Airlines flight 2036, a Boeing 737-700, N303DQ, collided with Delta Airlines flight 787, a Boeing 757-300, N583NW, while N303DQ was taxiing to the gate after landing at Atlanta Hartsfield International Airport (KATL), Atlanta, Georgia. At the time of the accident, N583NW was stopped on the taxiway. There were no injuries to any of the passengers or crewmembers on either airplane. N583NW received substantial damage to its right horizontal stabilizer and elevator and N303DQ sustained minor damage to its left winglet. Night visual meteorological conditions prevailed at the time of the accident. After landing on runway 9R, N303DQ exited onto taxiway N10 and was directed by the local controller to "make a right turn on taxiway N, snug up on a 757, your gate is occupied." The B757, N583NW, was stopped on taxiway N east of taxiway J, facing east, awaiting clearance to taxi to their gate. N303DQ stopped on taxiway N, west of taxiway J. Approximately 15 minutes later, the local controller directed N303DQ to make a right turn on taxiway J and hold short of runway 9R to taxi the flight to ramp 1 via taxiway R. The captain of N303DQ indicated that he looked out his left window and it appeared there was sufficient clearance with the N583NW, however, the flight crew felt the airplane shudder as the turn was completed and stopped the airplane ahead. Immediately, N583DQ reported to the local controller that they thought that their airplane had been hit from behind. The captain of N303DQ confirmed to the local controller that their left winglet was damaged. Airport rescue crews were dispatched and inspected both aircraft and then both airplanes taxied to their gates without further incident. The right horizontal stabilizer and elevator on N583NW were substantially damaged.
