Fuel control switches to the engines of an Air India flight that were killed shortly after taking off, killing 260 people from the “run” to the “cutoff” position moments before Impact, according to a provisional investigation report.
The report, published by the India’s Aircraft Accident Investigation Bureau, did not give any conclusions or distribution to the 12 June, but indicated that one pilot asked the other why he cut off fuel, and the second pilot replied that he had not done that.
The Boeing 787-8 Dreamliner went from Ahmedabad in West India to London when it crashed, which killed one after all 242 people on board, as well as 19 people on the ground.
In his 15 -page report, the research agency said that as soon as the aircraft reached its upper registered speed, “the Engine 1 and Engine 2 fuel switches switched from run to closing from one after the other with a time slit of 1 sec”.
“In the cockpit, one of the pilots is heard to ask the other person why he cuts off. The other pilot replied that he didn’t,” said it.
The plane started to lose the altitude quickly.
The switches then returned to the run position and the engines seemed to collect strength, but “one of the pilots that was transferred” Mayday Mayday Mayday “, said the report.
Air traffic controllers asked the pilots what was going on, but then saw the plane crashing and called emergency service to the scene.
The report did not determine what comments were made by the captain of the flight and which sent the Mayday signal by the first officer, nor which pilot.
At the crash location, both fuel switches were found in the run position and the report said there had been indications that there were both engines that had returned before the low height crash.
Both pilots were experienced jet pilots with around 19,000 total flying hours between them, including more than 9,000 out of 787.
The provisional report also does not say how the switch could be on the flight to the Cutoff position.
The American aviation safety expert Anthony Brickhouse said that an important question is why the switches have been moved in a way in a way that is not consistent with normal operations.
“Did they only led or have they moved because of the pilots?” he asked. “And if they have been moved because of a pilot, why?”
The American aviation safety expert John Cox said that a pilot could not accidentally move the fuel switches that feed the engines. “You can’t bump them and move them,” he said.
Cut to close, the engines cuts almost immediately. It is usually used to switch off engines as soon as an airplane has arrived at the airport gate and in certain emergency situations, such as a motorcycle fire. The report does not indicate that there was an emergency for which the engine was needed.
The agency said that “there were no recommended actions for B787-8 and/or GENX-1B Motor Operators and manufacturers”, which does not suggest technical problems with the motors (ge) or the aircraft (Boeing).
The agency said the investigation was underway and that additional evidence and information “were sought from the stakeholders”.
The plane wore 230 passengers – 169 Indians, 53 British, Seven Portuguese and a Canadian – together with 12 crew members.
Dozens of people were injured on the ground.
A passenger survived in a wonderful way, a British citizen who was seen from the wreck of the crash and who has since been released from the hospital.
