Air India crash report reveals pilot confusion over fuel cutoff switches

NEW DELHI — A preliminary report depicted confusion in the cockpit shortly before an Air India jetliner crashed and killed 260 people last month, after the plane's engine fuel cutoff switches flipped almost simultaneously and starved the engines of fuel.

The Boeing 787 Dreamliner bound for London from the Indian city of Ahmedabad began to lose thrust and sink shortly after takeoff, according to the report on the world's deadliest aviation accident in a decade released on Saturday by India's Aircraft Accident Investigation Bureau.

The report about the June 12 crash raises fresh questions over the position of the critical engine fuel cutoff switches.

Almost immediately after the plane lifted off the ground, closed-circuit TV footage showed a backup energy source called a ram air turbine had deployed, indicating a loss of power from the engines.

In the flight's final moments, one pilot was 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 commanding pilot of the Air India plane was Sumeet Sabharwal, 56, who had a total flying experience of 15,638 hours and, according to the Indian government, was also an Air India instructor. His co-pilot was Clive Kunder, 32, who had 3,403 hours of total experience.

The fuel switches had almost simultaneously flipped from run to cutoff just after takeoff. The preliminary report did not say how the switches could have flipped to the cutoff position during the flight.

"We care for the welfare and the well-being of pilots so let's not jump to any conclusions at this stage, let us wait for the final report," Civil Aviation Minister Rammohan Naidu told local news channels.

Air India acknowledged the report in a statement. The carrier said it was cooperating with Indian authorities but declined further comment.

Error in doubt

Experts have said a pilot would not be able to accidentally move the fuel switches.

"If they were moved because of a pilot, why?" asked United States aviation safety expert Anthony Brickhouse.

The switches flipped a second apart, the report said, roughly the time it would take to shift one and then the other, said US aviation expert John Nance. He said a pilot would normally never turn the switches off in flight, especially as the plane is starting to climb.

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.

At the crash site, both fuel switches were found in the run position and there had been indications of both engines relighting before the low-altitude crash, the report said.

Asked about the report, the father of first officer Kunder told reporters "I am not from the airline", declining to comment further during a prayer meeting held in memory of the airline's crew on Saturday in Mumbai, where emotional scenes played out among grieving relatives.

The US National Transportation Safety Board thanked Indian officials for their cooperation in a statement and noted there were no recommended actions in the report aimed at operators of Boeing 787 jets or the General Electric engines.

The US Federal Aviation Administration said its priority was to follow the facts where they lead and it was committed to promptly addressing any risks identified throughout the process.

Boeing said it continued to support the investigation and its customer, Air India. GE Aerospace did not respond immediately to a request for comment.
