Delta Air Lines Flight 2503

On August 15, 2017, at approximately 6:15 PM EDT, American Airlines flight 290, a Boeing B757, N175AN, was stationary awaiting takeoff clearance when it was struck by Delta Air Lines flight 2503, a Boeing B737-800, N377DA, as it was taxiing at John F. Kennedy International Airport (KJFK), Queens, New York. There were no injuries to the 129 passengers and crew onboard the B757, nor to the 166 passengers and crew onboard the B737. The American Airlines B757 sustained substantial damage and the Delta Air Lines B737 sustained minor damage. Both airplanes were operating under 14 CFR Part 121 as regularly scheduled passenger flights.

According to flight crew statements, the American Airlines B757 taxied down taxiway C and turned onto taxiway FB where it stopped short of runway 22R and was awaiting takeoff clearance. The Delta B737 followed the American B757 down taxiway C and was then instructed to taxi behind the American B757 and to continue to taxiway E. The Delta captain stated he steered slightly to the right of the taxiway centerline to keep clear of the stopped American B757. He then steered back towards the centerline once he thought his left winglet had cleared the American B757s tail when he felt a bump. After stopping, emergency personnel inspected both airplanes and indicated that Delta's left winglet had contacted the American B757 right horizontal stabilizer, resulting in substantial damage to the elevator. Both aircraft taxied back to their respective gates under their own power and passengers deplaned normally.
