According to a report published on Wednesday by The Wall Street Journal quoting sources close to United States officials’ early assessment of evidence, the black box audio recording of the last conversation between the two pilots indicates that the captain might have turned off the switches controlling the flow of fuel to the plane’s engines.

WSJ reports the plane's two switches moved to "cutoff" position seconds after lifting off the runway but were found in "run" mode at crash site.

Air India has completed the inspection of fuel control switches on Boeing 787 planes with no issues being found, Indian broadcaster NDTV said on Wednesday, citing an official.
