On July 16, 2023, an aviation incident occurred when ITA Airways flight 610 and Endeavor Air flight 4994 collided while taxiing at John F. Kennedy International Airport (JFK). The collision resulted in significant damage to both aircraft. ITA Airways flight 610, scheduled for international passenger service, was taxiing under 14 Code of Federal Regulations Part 129, while Endeavor Air flight 4994, operating as a regularly scheduled passenger flight, was taxiing under 14 Code of Federal Regulations Part 121. The Endeavor Air flight entered the Terminal 4 ramp and proceeded to taxi to gate B44. The Endeavor Air crew reported clearing the ramp and taxiing to their assigned gate, but the Endeavor Air flight crew then turned onto taxiway KF, causing a collision with ITA Airways flight 610. The ITA Airways flight crew, monitoring from the cockpit, detected the Endeavor Air airplane turning and approaching the ramp. The ITA Airways flight crew then reduced ground speed and, based on their observation, assumed the Endeavor Air airplane was clear. However, the Endeavor Air flight crew reported a severe shaking, which prompted them to look out the left side of the airplane and observed that the ITA Airways airplane was missing its right winglet. This led the Endeavor Air crew to conclude that the ITA Airways airplane may have been struck and instructed ATC to maintain stationary until damage was confirmed. Following the incident, an inspection revealed substantial damage to the Endeavor Air airplane’s right elevator and horizontal stabilizer structure, and minor damage to its right winglet. The probable cause was a misjudgment by the ITA Airways flight crew regarding the clearance between their airplane and another airplane on an adjoining taxiway.On July 16, 2023, an aviation incident occurred when ITA Airways flight 610 and Endeavor Air flight 4994 collided while taxiing at John F.
