India’s aviation regulator has ordered the country’s airlines to examine fuel switches on Boeing aircraft, after a preliminary report on the Air India flight 171 crash in June showed the fuel supply had been cut seconds after takeoff. South Korea was also preparing to order all airlines in the country that operate Boeing jets to examine the switches. A preliminary report, released on Saturday, found both engines of the Boeing 787 Dreamliner, which crashed, killing 260 people, had been starved of fuel, leading investigators to focus on the fuel switches in the cockpit. Both switches were moved back to allow fuel to flow, but the plane was too low and slow to recover. The Indian Commercial Pilots’ Association (ICPA) said it was “deeply disturbed by speculative narratives … particularly the reckless and unfounded insinuation of pilot suicide”.
