Air India plane's fuel switches were cut off before crash, report finds

A preliminary report into the Air India passenger plane crash that killed at least 270 people last month has found that both engines were flipped to cut off after takeoff.

The 15-page report released Friday by India's Aircraft Accident Investigation Bureau found that the cutoff switches for both engines were switched, one after another, within one second. The switch led to both engines losing thrust. Investigators were able to get data out of the black boxes.

"In the cockpit voice recording, one of the pilots is heard asking the other why did he cutoff. The other pilot responded that he did not do so," the report reads.
