NEW DELHI -- Both engines of the recently crashed Air India airplane had shut down mid-air within seconds of take-off, showed a preliminary investigation report released on Saturday by the Indian Aircraft Accident Investigation Bureau (ABI).

According to Indian media, the report said that before the Flight AI-171 plane crashed, the switches controlling the fuel flow of the two engines switched from "RUN" to "CUT OFF" within a second of each other, which caused the aircraft engines to stop working. The cockpit voice recorder shows that one of the pilots asked, "Why did you cut off?" and the other pilot replies, "I didn't."

The accident report also showed that both switches were moved back to the "RUN" position and while Engine 1 showed signs of recovery, Engine 2 could not.

"The CCTV footage obtained from the airport showed Ram Air Turbine (RAT) getting deployed during the initial climb immediately after lift-off. No significant bird activity is observed in the vicinity of the flight path. The aircraft started to lose altitude before crossing the airport perimeter wall," the report said.

The report noted that the RAT was deployed, indicating a total loss of power and thrust in the aircraft. The report also showed that the flap settings and landing gear positions were normal at the time of the crash.

The report said that these facts will become a focus area for future investigations.

The London-bound Air India aircraft, a Boeing 787-8 Dreamliner, crashed on June 12 shortly after takeoff from the Sardar Vallabhbhai Patel International Airport in Ahmedabad, about 17 km south of Gandhinagar, the capital city of India's western state of Gujarat, killing all but one of the 242 people on board and 19 others on the ground.
