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.

Cockpit audio from Air India flight indicates fuel supply may have been cut off by the captain, according to the WSJ. The pilots' body rejected the claim.

Authorities released a preliminary report on the Air India crash, following an investigation. The London-bound flight from Ahmedabad crashed minutes into the June 12 flight. Only one passenger of the 242 passengers and flight crew survived.
