A Delta Airlines Airbus A350-900, registration N519DN performing flight DL-200 from Atlanta,GA (USA) to Johannesburg (South Africa), was climbing out of Atlanta's runway 27R when the crew stopped the climb at 10,000 feet declaring Mayday and reporting that they had lost autopilots and autothrust, they needed to return to Atlanta. The crew requested to hold while they were working out the return and received vectors. The aircraft landed overweight but safely back on Atlanta's runway 27R about 105 minutes after departure. The aircraft stopped on the runway with hot brakes and was towed to the apron.
The rotation DL-200/DL-201 was cancelled.
