Preliminary reports on last month’s deadly India collapse showed chaos in the cockpit after the plane’s engine fuel cutoff switch flipped almost simultaneously and starved the fuel engine to death.

Indian accident investigators report did not say how the switch was transferred to the cutoff position during flight.
Chen: “From reading, I found…”
A former pilot and senior lecturer at Marco Chan, a new university in Buckinghamshire, said he believes the chip failure that caused the crash, rather than human error.
He pointed to a previously issued service announcement by engine manufacturers, recommending maintenance of defective chips to prevent signal loss.

“I believe FAA, along with GE, General Electric (engine manufacturer), has issued a service announcement that I believe it is about 11,000 cycles and they will have to replace the chip. And if it is not replaced or maintained correctly, it can cause intermittent loss of the signal. Once you have no loss of the signal.
Chen said it would be a challenge for pilots to accidentally move the switch to the cutoff position.
“You have to do some physical approach – don’t pull the pin – but if you have to remove the toggle, then it can be moved to another position. So you have to do this on purpose instead of accidentally hitting it in the wrong position. This rarely happens, or is close to zero.”

The report shows that both fuel switches were found in the operating position at the crash site and there were signs that both engines were re-determined before the crash was low.
The Boeing 787 Dreamliner travels to London from Ahmedabad, India.
The crash caused 260 people, making it the deadliest aviation accident in the world in a decade.
