A recorded dialogue between the two Boeing 787 operators crashed last month in Ahmedabad, India, indicates that he was the most experienced of the two, the commander, who interrupted the power supply of the engines with fuel, said in fuel.
The newspaper quotes its sources in the US, aware of the initial assessment of data gathered and analyzed about this accident, which claimed the lives of 260 people, occupants at 787 and people on the ground on June 12th.
The co -pilot, in the 787 rolling of the 787, asked the very experienced ruler why he turned the switches to regulate the power of the two engines to the cutting position, seconds after the long -distance aircraft, which would fly to London.
Cleive Kunder, 32, was 3,403 -hour experience, while Sumit Sampaual, 56, with a 15,638 -hour volatile experience was ruled. The latter denied he did.
During the preliminary finding of the accident investigation, released on Saturday by the Indian Air Force Research Service (AAIB), the long -distance passenger aircraft had developed a speed of 180 knots (333 kilometers per hour) and had just taken off when the switches were opened. (“Cutoff”), with a second one from each other. The text is not specified by whom. The engines immediately lost every power.
The audio that probably gives the answer
The preliminary finding did not attribute responsibility for the accident, but stressed that one of the pilots asked the other why he stopped supplying the engines with fuel – the other replied that he had not done so. The plane lost height and fell on buildings in half a minute.
Images from cameras on the airport surveillance system recorded that a small, auxiliary turbine (RAM Air Turbine, Rat), was put into operation shortly after take -off. It is part of the Auxiliary Power Unit (APU), designed for the electricity of the aircraft systems of the aircraft in the event of the engine stoppage, or when on the ground.
In the wreckage after the accident, the switches were found in the “Run” position. The data from the flight data recorder indicates that the engines took back just before the crash, but it was too late to prevent.
There was no mechanical problem
In his internal document on Monday, Air India CEO Campbell Wilson said the finding had shown no problem, engineer or maintenance, of Boeing 787, on the contrary, he said that every required maintenance had been done.
AAIB’s preliminary finding does not formulate any security recommendation, neither in Boeing nor on the GE engine manufacturer. Informing the US Federal Service of the US, FAA, he also assured that the switches are completely safe, according to the Reuters News Agency, whose knowledge was made.
A total of 241 people aboard Air India’s Boeing 787-8 Dreamliner were killed-just one survived-when the aircraft crashed on buildings a short distance from Ahmedabad airport. The Indian authorities also identified 19 victims on the ground.
Patience for the final finding
Some US officials cited by the WSJ estimated that the interruption of fuel engine supplies could be deliberate, considering that the investigation may now have a forensic nature.
Mr Wilson called on earlier this week not to draw hurried conclusions from the preliminary findings and other available evidence, stressing that the investigation is still “far away” from being completed.
Investigations into air accidents often last over a year or more; in addition, it is generally difficult to determine any intentional action to cause accident. In some cases, experts from one country disagree with the conclusions of another, the newspaper noted.
