NEW: Air India Flight AI-171 crashed 32 seconds after takeoff because both engine fuel control switches were moved from RUN to CUTOFF seconds after liftoff, cutting fuel supply and shutting down both engines.
Investigators found no mechanical failure in the aircraft. The preliminary report states the switches were moved sequentially about one second apart, starving the engines of fuel.
Roughly 10 seconds later, the switches were moved back to RUN and the engines attempted an automatic restart, but the aircraft was already too low to recover.
Cockpit audio reportedly captured one pilot asking, “Why did you cut off?” with the other replying, “I did not do so.”
