 Once again, the automatic safety system closed the right engine throttle and the captain, who was conducting the takeoff, called for the autothrottle system to be switched off.After switching off the system, the copilot again pushed the right engine power lever fully forward and forcefully held it there.The safety system cable, responsible for pulling the power lever to the idle position, was no longer able to withstand the physical strain of being pulled one way by the actuator, while the copilot forced it the other way by pushing the throttle lever to the fully open position — the cable soon parted at a maintenance connection.
