July 18 (Reuters) - A cockpit recording of dialogue between the two pilots of the Air India flight that crashed last month supports the view that the captain cut the flow of fuel to the plane's engines, said a source briefed on U.S. officials' early assessment of evidence.

New details from the Air India crash probe show that both engines of the Boeing 787 lost power right after take-off from Ahmedabad, likely due to a sudden fuel cutoff.

Fuel-control switches give pilots direct control over the fuel supply to the engines so that they can manually turn one of them off in case of a fire or any other emergency while mid-air

Cockpit recordings from the Air India crash reveal pilot confusion after fuel cutoff switches mysteriously flipped during takeoff, causing engines to lose power in the disaster.
