On Saturday, India's Air Accident Investigation Bureau released a report revealing that the fuel control switches on the Boeing 787 were set to "cutoff" just seconds after takeoff, explaining why the widebody jet failed to gain sufficient lift after rotation, as thrust could not be produced with Jet A fuel supply cut off.

"The aircraft achieved the maximum recorded airspeed of 180 Knots IAS at about 08:08:42 UTC and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec. The Engine N1 and N2 began to decrease from their takeoff values as the fuel supply to the engines was cut off," the report read.
