Listen: Air France jet makes a wrong turn after takeoff from LAX and comes within 400 feet of an American Airlines plane

An Air France Airbus A350 and an American Airlines Airbus A321 came dangerously close shortly after departing Los Angeles International Airport early Saturday, after the Air France crew turned off its assigned departure route, AeroTime reported.

Air France Flight 28, bound for Papeete, Tahiti, took off from Runway 24L, and American Airlines Flight 1660, headed for Dallas/Fort Worth, took off from Runway 25R a minute later. The Air France crew had been cleared on the SUMMR2 departure, but the A350 began an unexpected left turn that put it toward the American jet's path. Flight-tracking data showed the planes came within about 400 feet of each other vertically.

In air traffic control audio, the controller ordered Air France to turn immediately to a heading of 270 and told the American crew, which was climbing out of 2,000 feet, to stay at 2,000. He warned the American pilots of traffic at their 12 o'clock, less than a mile away.

The controller then pressed the Air France pilots on why they had turned and which departure they had been told to fly. The crew answered "standby" before confirming SUMMR2, and the controller told them of a possible pilot deviation and gave them a phone number to call. Both flights continued to their destinations, and no injuries or damage were reported.
