A preliminary finding into last month’s Air India plane crash has suggested the aircraft’s fuel control switches were turned off, starving the engines of fuel and causing a loss of engine thrust shortly after takeoff.

On June 12, Air India’s Boeing 787-8 aircraft operating flight AI 171 en-route to London Gatwick crashed into a medical hostel complex soon after take-off from Ahmedabad, killing 260 people, including 241 persons who were onboard the plane. One passenger survived the crash.
