A preliminary report into the Air India crash last month finds that both fuel control switches were moved to cut-off position - a step that usually turns off the engines - moments before the plane crashed
Cockpit voice recording shows confusion between the two pilots. One is heard asking his colleague why he "did the cut-off" - and the other pilot said he did not do so, the report says
An Air India spokesperson says it continues to "fully cooperate" with authorities,BBC reported.
At least 260 people were killed in the crash, and the sole survivor - British national Vishwashkumar Ramesh - escaped the wreckage through an opening in the fuselage
