A cockpit voice recording of doomed Air India Flight 171 indicates that it was the younger co-pilot who asked his more experienced colleague why he turned off the plane’s fuel-supply switches, according to people familiar with the matter.

A cockpit voice recording from the Air India crash in Ahmedabad suggests the plane's captain may have cut fuel to the engines seconds after takeoff, shifting the investigation’s focus to pilot actions rather than mechanical failure.

Fuel control switches for the engines of an Air India flight that crashed last month were moved from the “run” to the “cutoff” position moments before impact, starving both engines of fuel, a preliminary investigation report said early Saturday.
