The Air India airliner carrying 230 passengers and 12 crew members was on its way to the United Kingdom when it crashed into a building shortly after takeoff on June 12, killing all aboard, except for one survivor, and several people on the ground, according to authorities.

Preliminary findings into last month’s Air India plane crash suggest the aircraft’s fuel control switches were turned off, causing a loss of engine thrust shortly after takeoff.

The preliminary report into the crash referred to a 2018 FAA advisory, which recommended that operators of several Boeing models inspect the locking feature of the fuel-cutoff switches. The report said Air India did not carry out the inspections.
