Boeing investors finally have details from a preliminary accident report for Air India flight 171, which crashed on June 12 less than a minute after taking off from an airport in Ahmedabad, India.

The AAIB released its preliminary findings on Saturday, offering early insights into what has become one of the deadliest aviation incidents globally in over a decade.

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.
