Phoenix Air Traffic Controller Prevents Collision Between Two American Airlines Flights Sharing Same Call Sign

A Phoenix-based air traffic controller prevented a potential midair collision Friday when he discovered two American Airlines aircraft were simultaneously airborne under the identical call sign American 2482. Working shortly after midnight, the controller rapidly implemented separation procedures to keep the planes safely distant as one arrived from Chicago while the other departed Phoenix.

Audio recordings posted by ATC.com reveal the controller’s solution: immediately distinguishing between the aircraft by referring to “American 2482 on the arrival” and “American 2482 on the departure.” He maintained precise altitude separation between the converging flight paths and ensured both pilots visually identified one another while still miles apart, while also instructing the departing aircraft to limit its climb rate.

The controller, who emphasized he had never encountered such a scenario in 25 years of service, acknowledged the severity of the situation. Had both pilots misinterpreted instructions regarding altitude assignments, they could have flown directly toward each other at dangerous proximity.

Aviation safety expert Steve Arroyo attributed the error to American Airlines’ dispatch center failing to detect the scheduling overlap. Arroyo, who spent four decades with United Airlines beginning as a dispatcher, noted such incidents are extremely rare but highlighted how air traffic control safeguards proved effective.

Flight 2482 operates regularly between Chicago and Phoenix. A weather delay of the Chicago departure prompted American to deploy a second aircraft from Phoenix, resulting in temporary airspace overlap before the arriving flight landed.

The Federal Aviation Administration and American Airlines said they will jointly investigate the incident, both expressing relief that separation requirements were continuously maintained throughout the encounter.
