(Reuters) -A preliminary report into the Air India crash that killed 260 people last month showed the plane's engines fuel cutoff switches almost simultaneously flipped from run to cutoff, starving the engines of fuel.

The two engines on the Air India flight shut down within one second of each other before the Boeing 787 Dreamliner crashed last month in Ahmedabad, India, killing at least 260 people, according to a preliminary report released Friday.

The fuel switches to both engines on the Air India Flight 171 moved to the "cutoff" position immediately before the crash that killed 260 after taking off on June 12.
