B772 / B739, New York JFK USA, 2023

Summary

On 13 January 2023, in good night visibility, a Boeing 777-200 with an augmented crew did not comply with its departure taxi clearance and crossed a runway in front of a 737 on the takeoff roll. ATC responded to an automated conflict warning by cancelling the takeoff clearance, and the 737 initiated a high-speed rejected takeoff from approximately 105 knots. Minimum separation as the 777 cleared the edge of the departure runway was approximately 300 metres. The investigation concluded that the 777 operator’s risk controls and the airport’s methods for detecting and preventing runway conflicts were both inadequate.

The 777 crossed in front of a Boeing 737-900 (N914DU) operated by Delta Airlines on a scheduled international passenger flight from New York JFK to Santo Domingo as DAL 1943, which was taking off as cleared. An automated alert prompted Air Traffic Control (ATC) to cancel the 737s takeoff clearance and as the 777 completed its unauthorised crossing. The minimum separation as the 737 decelerated was approximately 300 metres.
