An Arizona air traffic controller's rapid response averted a potential mid-air collision between two American Airlines planes sharing the same flight number and frequency. The incident occurred early Friday morning as one flight was arriving in Phoenix and another was departing.
The controller, who has 25 years of experience, recognized the dangerous situation when both aircraft, identified as American 2482, communicated with him simultaneously on the same frequency. To prevent confusion, the controller distinguished the planes as "American 2482 on the arrival" and "American 2482 on the departure."
The controller meticulously managed the situation, ensuring the arriving plane maintained a safe altitude above the departing aircraft. He also directed the departing flight to limit its climb to maintain separation as their paths converged. The pilots were able to visually confirm each other's presence while still miles apart.
Audio recordings of the event captured the controller's astonishment, stating he had "never seen two aircraft pretty much merge with the same call sign." The pilot of the arriving flight commended the controller for his "nice work" once the planes had safely passed each other. The controller acknowledged the severity, noting, "It could have been disastrous, but I'm glad it worked out."
An aviation safety expert suggested that the error likely originated in the airline's dispatch center, where the duplicate flight numbers were not caught during the flight plan approval process. This type of oversight, while rare, highlights the importance of the system's safeguards and the critical role of air traffic controllers. The expert, who has witnessed similar issues only a few times in his four-decade career, noted the system's resilience.
American Airlines stated that the "diligence and professionalism of air traffic controllers and our pilots ensured required separation was always maintained and the issue was identified and addressed. Both flights continued safely and without incident."
Flight 2482 is typically a round-trip route between Chicago and Phoenix, often utilizing the same aircraft. However, a weather delay for the outgoing flight from Chicago led American Airlines to assign a different aircraft for the return leg departing from Phoenix. This operational change resulted in both aircraft briefly operating under the same flight number in shared airspace before the arriving flight landed safely.
