A preliminary report by Indian aviation accident investigators said on Saturday the fatal Air India crash that killed 260 people in Ahmedabad last month showed the plane engines fuel cutoff switches shifting from cutoff to run within seconds of each other.

Investigators are probing the wreckage and cockpit recorders to understand what went wrong just after take-off. The Air India flight climbed to 625 feet in clear weather before losing location data 50 seconds in, per Flightradar24. Saturday's 15-page report offers early insights.

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.
