The official investigation of tragic incident with Air Indian Air Air Air Air Air focused on the thrust of Boeing 787 engine, click and chassis, while aviation maintenance is also closely noticed.
Now, a black box has been extracted from under the rubble of the aircraft, the Indian Department to investigate the aviation accidents to find whether the traction of the engine and shutters on the wings of the aircraft is active or not, as well as why the chassis is still open, writing The Guardian.
According to Reuters involved in a source of information, investigators will also find out whether Air India's faults are available or not, including missing problems.
The pilot died Boeing 787 in India has planned to end his career
The AI171 flight offered a signal of suffering for air traffic control for a moment after taking off from Ahmadabad on Thursday, almost did not leave the runway, when he began to refuse and stab into the building, because all 242 people were on the train, except for one person, reminding the guard.
While the digital autonomy of the flight data is found on the roof of the building, the recording machine of the pilots' cabin, can clarify the actions of the pilots, are not found.
According to Reuters, a clash with birds, leading to the refusal of two engines, leading to an incident with a great landing of Airways flight in 1549 in 2009 on the Hudson River in New York and proposed by some experts as a possible explanation, not one of the important areas. On the frames from the video surveillance camera, the dust clouds can be seen during the process, but there is no bird.
According to sources, investigations have the participation of experts in fighting terrorism. U.S. and UK officials participated in the investigation conducted by India.
Warning against hasty conclusions, aviation analysts offered some theories about the possible causes of tragedy – the first dead airline with the participation of Boeing 787 Dreamliner.
Dr. Sonya Brown, a senior teacher of the aerospace design at the University of New South Wales, note that the frames show the plane delayed.
For me, this really looks like losing significant traction. The lifting force of the aircraft is proportional to the speed square, so if you do not have traction and you lose speed – and radar data shows that after the initial short height, the speed of decline, you may be delayed, Braun said.
According to Dr. Brown, the reason for the lack of traction is still unclear.
According to some analysts, the video shows that the aircraft flap is not released during the Take -off process. The panels of the aircraft can be given to create lifting force and are the key to the process of taking and landing – at the moments of the flight when most aviation accidents occur.
However, Brown emphasized that even when the flap is not released, the dumping can be avoided when increasing the thrust, adding that one of the reasons may be the wrong adjustment of the thrust due to human errors. She also noted that although the modern plane, he was 11 years old, so he could study improper maintenance.
Despite the pilot fault that is the hidden cause of any survey of the plane crash, captain Air India Sumit Sabharval and the second pilot Klive Kundar have a lot of experience; Over 22 years of working, the pilot of Sabharwal commercial airline has flew for more than 8,000 hours, recalling The Guardian.
Questions about the fuselage do not arise as deeply as after the Boeing 737 MAX plane crash in 2018 and 2019, occurred shortly after this model works.
Despite the fact that the Air India aviation regulator has ordered safety for the remaining 33 Boeing 787 aircraft, Indian airlines and airlines around the world have operated this model for more than ten years and they have a relatively small problem, notes.
Air India is also ordered to take additional maintenance measures of the Air fleet, equipped with GE Aerospace engine, not Rolls – Royce Trent 1000 engine installed on many Boeing 787, have been suspended in recent years to eliminate defects.
Neil Hansford, a former pilot and president of a strategic aviation solution consulting company, believes that other versions that investigators must consider and regard their potential destruction, pay attention to political tensions in Gujarat state, the capital of Ahmadabad.
Another chance, according to him, may be polluted by fuel. It is known that the fuel tank of the aircraft is almost full, but Hansford said that pollution can lead to congestion.
Playing fuel can lead to engine problems, he said.
Boeing -787 is a two -person aircraft, but it can fly on a engine, is one of many reservation levels -from reserve energy sources, computer monitoring systems, such as automation and planning capabilities -in modern aviation industry, although this last tragedy is one of the best tragedies. The safest modes of statistics.
But Sonya Brown Note: All of these measures are more effective if you have time, but it happened right after taking off. If you have the same problem at a height of 40,000 feet, this is not the same as a height of 400 feet. Simply there is not much backup at this height.
