The preliminary report of the Indian office in the field of air tickets (AAIB) presented this Saturday attributes of fuel supply failure, such as the cause of the Boeing 787-8 Dreamliner Applymer Air India, which crashed on June 12 in Ahmedabad.
The accident on the plane that made the AI171 flight between Ahmedabad, Western India and London, left 260 deaths, including 242 people on board and 18 on Earth, after exposure to the BJ medical college near the airport. Just the passenger survived.
When on the same day AAIB notified the accident, AAB displayed a team of five officers. Three other officials of the DGAC air security department joined to help collect evidence and other events.
According to the document, “the fuel switches of both engines were almost simultaneously operated three seconds after take -off, leaving the motors without movement and leading to a quick loss of height.”
In the voice records found in the cabin, “one of the pilots asks the other why he reduced the fuel supply, to which he replied that he did not do this,” the report said. The data is delivered from black boxes restored by researchers, who registered 49 flight hours and two hours of sound sound.
According to the report: “When the fuel control switches change from the cutting position to the launch, when the aircraft is in flight, the double control system automatically activates the sequence and the power sequence released by fuel.”
Soon after the reduction, the switches were returned to the position of the operation, and the engines began to reboot, but the plane had already critically lost his height.
He adds that a few seconds after an attempt to reactivation, one of the pilots published an emergency message: “Mayday, Mayday”, and although the air controller tried to make contact, he did not receive an answer and became a witness to the accident at a distance.
Air India said that among 242 passengers there were 169 Indians, 53 British, seven Portuguese and Canadians.
The report does not attribute duties and does not establish the final conclusions due to the accident and indicates that “the switches are located in the central console of the cabin, are protected by a metal rod and security mechanism, which avoids its accidental activation.”
