by Aircraft Accident Investigation Bureau said that the airline manufacturer said that it will defer the details to the agency on the basis of United Nations aviation protocol. Boeing President and CEO Kelly Ortberg said, “Our deepest condolences go out to the loved ones of the passengers and crew on board Air India Flight 171, as well as everyone affected in Ahmedabad. I have spoken with Air India Chairman N. Chandrasekaran to offer our full support, and a Boeing team stands ready to support the investigation led by India’s Aircraft Accident Investigation Bureau.”

"Boeing will defer to India’s Aircraft Accident Investigation Bureau (AAIB) to provide information about Air India Flight 171, in adherence with the United Nations International Civil Aviation Organization protocol," said the Boeing top boss.

A preliminary report into the Air India crash that killed 260 people last month showed three seconds after taking off, the plane's engines fuel cutoff switches almost simultaneously flipped from run to cutoff, starving the engines of fuel.

The Boeing 787 Dreamliner immediately began to lose thrust and sink down, according to the report.

One pilot can be heard on the cockpit voice recorder asking the other why he cut off the fuel. "The other pilot responded that he did not do so," the report said.It did not identify which remarks were made by the flight's captain and which by the first officer, nor which pilot transmitted "Mayday, Mayday, Mayday" just before the crash.The preliminary report also does not say how the switch could have flipped to the cutoff position on the June 12 London-bound flight from the Indian city of Ahmedabad.

Flipping to cutoff almost immediately cuts the engines. It is most often used to turn engines off once a plane has arrived at its airport gate and in certain emergency situations, such as an engine fire. The report does not indicate there was any emergency requiring an engine cutoff.
