According to the report obtained by CNN, the control switches in the cockpit of the Boeing 787 Dreamliner had been flipped, resulting in engine problems.

The aircraft had reached an airspeed of 180 knots when both engines’ fuel cutoff switches were “transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec,” according to the report.

“In the cockpit voice recording, one of the pilots is heard asking the other he cut it off. The other pilot responded that he did not do so,” the report reads.

Takeoff values began to decrease in the engines, according to the report, and fuel supply to the engines was cut off.

Airport footage shows the Ram Air Turbine, an emergency power source on an aircraft, deployed during the plane’s initial climb after take-off, the report said.

The plane started to lose altitude before crossing the airport perimeter wall.

No significant bird activity is observed in the vicinity of the flight path, according to the report.

Shortly after, both engines’ fuel switches are transitioned from CUTOFF to RUN.

“When fuel control switches are moved from CUTOFF to RUN while the aircraft is inflight, each engine’s full authority dual engine control automatically manages a relight and thrust recovery sequence of ignition and fuel introduction,” the report states.

Seconds after the engines attempted to relight, one pilot called out, “MAYDAY MAYDAY MAYDAY.”

The controller called out for the plane’s callsign, but didn’t get a response and watched the plane crash in the distance.

The captain of the flight was a 56-year-old male who flew over 15,000 hours in his career. The first officer was a 32-year old male with over 3400 flying hours.

In addition to those on board, a number of people on the ground were killed when the plane crashed into the BJ Medical College and Hospital hostel.

The Air India flight, AI171, took off from Ahmedabad’s Sardar Vallabhbhai Patel International Airport in India’s western state of Gujarat on June 12.

The Boeing 787-8 Dreamliner was headed to London Gatwick, and scheduled to land at 6.25pm local time.

Air India had said 242 passengers and crew members were on board. That included 169 Indian nationals, 53 Britons, seven Portuguese and one Canadian.
