A Phoenix air traffic controller averted a potential disaster Friday when he identified and separated two American Airlines jets that were mistakenly assigned the same flight number, 2482. The incident occurred shortly after midnight when one flight was arriving from Chicago and another was departing from Phoenix.
Audio recordings from the event reveal the controller's swift action in distinguishing between "American 2482 on the arrival" and "American 2482 on the departure." This clear communication ensured that the pilots maintained the required safe distance, especially as their flight paths converged. The controller strategically kept the arriving aircraft at a higher altitude than the departing one and instructed the departing plane not to climb excessively, thereby maintaining a crucial separation.
"I’ve been working air traffic for 25 years. I’ve never seen two aircraft pretty much merge with the same call sign. That’s pretty incredible," the controller stated after the departing aircraft had safely cleared the airspace. The pilot of the arriving flight acknowledged the controller's "nice work" as the planes passed each other.
An aviation safety expert, Steve Arroyo, suggested that the oversight likely originated from the airline's dispatch center, where the overlapping flight plan may have been missed. Arroyo, who has witnessed similar rare occurrences only a few times in his career, noted that while such errors are preventable, the system's safeguards proved effective. "You can drop the ball and that shouldn’t happen, but it’s nice to see that the system is resilient and we have all the safeguards," he said.
American Airlines typically operates flight 2482 as a round trip between Chicago and Phoenix using the same aircraft. However, a weather delay for the Chicago departure necessitated the use of a second plane from Phoenix, leading to the simultaneous presence of two aircraft under the same flight code in the shared airspace before the arrival landed.
Both American Airlines and the Federal Aviation Administration are conducting investigations into how the duplicate flight codes occurred. The airline stated, "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."
