July 12 (Reuters) - A preliminary report into the Air India crash that killed 260 people last month showed three seconds after taking off, the plane’s engines fuel cutoff switches almost simultaneously flipped from run to cutoff, starving the engines of fuel.

Errors made by two Air India pilots before the plane’s fatal crash will reportedly be the focus of an investigation into the tragedy. All but one of 242 people board the Boeing 787 Dreamliner died when the aircraft plunged into a medical student hostel in a built-up suburb last month, less than a minute after take-off from Ahmedabad airport.

A preliminary report on the Air India Boeing 787 crash in Ahmedabad reveals both engines lost power after a sudden fuel cutoff, leaving pilots unable to regain thrust before the disaster. The investigation continues as experts probe the cause.
