The Boeing 787 Dreamliner crashed less than a minute after take-off from Ahmedabad on June 12, killing all but one of the 242 people onboard

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.

The power minister proposed a rule in June requiring air conditioners sold in the country to have thermostats that can be set no lower than 20 Celsius (68 Fahrenheit).

The CEO of Air India sought to draw a line under rife speculation around the cause of last month's air disaster in Ahmedebad, saying the preliminary investigation had ruled out a mechanical cause for the crash.

A black-box recording of dialogue between the Air India flight's two pilots indicates it was the captain who turned off switches that controlled fuel flowing to the plane's two engines, the Wall Street Journal reported on Wednesday,
