Part 4/8:
During the climb, problems with the auto-throttle mechanism surfaced. The left engine throttle lever stuck due to ongoing issues, while the right throttle began to move back as the system intended. This condition—known as split throttle—demanded immediate attention from the pilots.
Unfortunately, the pilots were not actively monitoring the control levers or their engine instruments, believing the aircraft to be reliable. As the split throttle issue worsened, the aircraft began to roll to the left, exacerbating the precarious situation.
