Air India Crash investigation reveals fuel switch concerns, sparking Boeing 787 safety review and urgent inspections across airlines.

Authorities released a preliminary report on the Air India crash, following an investigation. The London-bound flight from Ahmedabad crashed minutes into the June 12 flight. Only one passenger of the 242 passengers and flight crew survived.

The 15-page preliminary report by Aircraft Accident Investigation Bureau (AIIB), released early on Saturday, has found that the fuel supply to both engines of Air India flight AI171 was cut off within a second of each other, causing confusion in the cockpit and the airplane plummeting back to ground almost immediately after taking off.
