Narrative:
On April 17, 2024, about 1646 eastern daylight time (EDT), Swiss Air flight 17K, an Airbus A330- 343, was involved in a runway incursion on runway 4L at John F. Kennedy International Airport (JFK), Jamaica, New York, due to four other aircraft crossing runway 4L. The four crossing aircraft were Delta Airlines flight 29, a Boeing 767-432(ER), Delta Airlines flight 420, an Airbus A220-100, Repulic Airlines flight 5752, an Embraer E175LR and America Airlines flight 2246, a Boeing 737-MAX 8 resulting in Swiss Air flight 17K rejecting their take-off. There was no damage to the involved aircraft nor injuries to crew or passengers. Swiss Air flight 17K was a Title 14 Code of Federal Regulations (CFR) Part 129 schedule international passenger flight from JFK to Zurich Airport (ZRH), Zurich, Switzerland.

History of Flight
At the time of the incident, the air traffic control tower (ATCT) was staffed with 10 Certified Professional Controllers (CPC), two trainees and one Operational Supervisor (OS). Staffing was in accordance with the shift guidelines with six controllers on position in the tower cab during the event. The OS on duty was not present in the control cab during the incident and a Controller in Charge (CIC) was providing general oversight. There was no on the job training (OJT) in progress during the time of the incident.

The following timeline was constructed from certified audio re-recordings and automatic dependent surveillance- broadcast (ADS-B) data provided by the Federal Aviation Administration (FAA). All times are in EDT and all speeds are in knots. A graphical depiction of the event with time and position of the involved aircraft is shown in figure 1. A graphical depiction of Swiss Air flight 17K speed and time is shown in figure 2.

Airport Surveillance Detection Equipment – Model X
JFK was equipped with surface detection equipment, called airport surveillance detection equipment – model X (ASDE-X). The ASDE-X alerts air traffic controllers of potential runway conflicts by providing detailed coverage of movement on runways and taxiways. Controllers are presented this information on a color display depicting aircraft and vehicle positions as icons overlaid on a map of the airport's runways/taxiways and airport approach corridors. The system continuously updates the map of the airport movement area that controllers can use to enhance their situational awareness. It's particularly beneficial at night or during inclement weather when visibility is poor.

The ASDE-X system is also equipped with visual and aural alarms that will alert controllers of possible runway incursions or incidents. The safety logic system is an integral part of the software system for ASDE-X. This software predicts the path of aircraft landing and/or departing, and/or vehicular movements on runways.

The ASDE-X system did not alarm during the event because SWR17K never transitioned into the departure state. An aircraft transitions to the departure state when the aircraft exceeds the departure states’ acceleration (1.3 m/s*s) AND velocity (24.384 m/s) thresholds.

Investigation
The NTSB was notified of the event and Operations, Air Traffic Control (ATC) and Human Factors specialist were assigned. The ATC group convened at JFK ATCT the week of April 30th to conduct interviews, review documentation and data. Parties to the investigation are FAA, National Air Traffic Controller Association (NATCA), American Airlines, Delta Air Lines, Republic Airlines, Air Line Pilots Association (ALPA), Allied Pilots Association (APA), and the International Brotherhood of Teamsters (IBT). The Swiss Transportation Safety Investigation Board (STSIB) provided an Accredited Representative, and Swiss International Air Lines are technical advisors to the STSIB.

The investigation continues.
