The report focused on the moments after the takeoff, showing the aircraft’s two fuel control switches moved to the ‘cutoff’ position in quick succession. This action cut off fuel supply to the engines, immediately causing the aircraft to lose all thrust.
The switches are on the centre console of the cockpit, just below the engine thrust levers. They are used to control fuel flow to the engines—primarily during engine start-up and shutdown on the ground, or to shut down an engine in the event of an engine failure during flight. //
The fuel control switches are equipped with a spring-loaded locking mechanism that keeps them in position and prevents unintended movement. You would have to pull the switch up before moving it from run to cutoff, or vice versa.
Aviation experts say a pilot would not have been able to move the fuel switches accidentally. Once moved, the effect would be immediate, cutting off engine power.
