As rotating on the weather conditions, the main details are unknown

Although the preliminary report was reported due to the loss of the loss of the flight in India last month, he gave some answers last month, and the reason for this was the wave of hypothesis.

Boeing 787 Dreamliner crashed into a minute of a minute from Ahmedabad, western India, on the road to London, 241 people killed 241 people on the floor. A passenger survived.

The report in the report of the Indian Aircraft Investigation Bureau, the first official account of what happened, raised the questions about the role of pilots.

However, experts claim that the investigators are highly voters in the event of investigators.

As part of the international protocols, the state of the air accident investigation is designed to provide an initial report within 30 days. A 15-page document published by the Indian Aircraft Investigation Bureau (AAIB) fulfills this request on Saturday.

Although AAIB investigates, Boeing, the manufacturer of the aircraft and Ge Aerospace producer, engine producer is American.

The report does not bring any conclusion due to the accident. Nevertheless, it caused a significant controversy.

After the accident, the two fuel cutting keys were removed from the “Shutter” from the “cut” position from the “cut” position from “Running”.

It deprived fuel engines and caused them to lose them. Although the flight printer shows the information, the engines were later restarted, it was too late to prevent the accident.

These switches are normally used only to turn off the engines before and after flight. There is a system that has a system, a system, which is a system designed to prevent random deployment, ie their locking mechanism.

The report also said that a pilot asked the other “why he cut” and my colleague “answered that he did not do it.”

However, the conversation to be selected by the Cockpit Sound Record (CVR) does not give a direct transcript. This does not determine which pilot asks questions.

Preliminary reports are worth remembering that it is not intended to offer a full picture of what is happening or to draw a strong result. They are expected to have an actual summary of information obtained in the early stages of what may be a long research.

The investigative authority is not an obligation to make its initial reports to the public.

The information has been released so far, in the media and online, a number of commentators caused a number of commentators to claim that the accident was intentionally and deliberately.

India is a landscape that attracts an angry response to the Trade Pilots Union, “It calls for such a serious claim based on incomplete or preliminary information, not only irresponsible – individuals and families.”

Added that “the proposal of the pilot suicide in the absence of evidence of accidental evidence is gross violation of ethical reports.”

A memorial to prepare staff hit a similar note to the CEO of Air India. Campbell Wilson warned against “Premature Results”.

Since the report was given BBC, pilots, accident investigators and engineers, a number of people in the industry. According to what is happening, theories, dominant landscape, are currently missing.

“We told us that they could not know what they wanted to know at the moment and did not know what they did not want to know.” It’s not a complete report. “

One of the main criticism is the lack of a transcript from the cockpit voice printer, which allows the stated conversation to the context of the fuel cutting keys.

Bjorn Fehrm, a aeronutic analyst of consultants Leeeham News said this is “completely unacceptable.”

“They have these technical details. Then you have this reference to the dialogue, but it does not tell you who is talking,” he said.

Mr. Fehrm did not have any reference to the cocpit in the cockpit between the keys, and the first pass was back to the position for the first engine 10 seconds.

“One thing that is trying to hide something,” he said.

Meanwhile, the engineering source said the report was “very voter” and the presenters had no detailed information about what they did immediately after the failure. The document says the engine speed starts reduced from the growth values “as the supply of fuel supplies to engines.” “

It was something that the pilot would be prepared to rebuild the switches, because they said they were important, because it was a pilot to restart the switches.

A aviation consultant in England and an investigator former air accident investigator Tim Atkinson, “Reading a report that offers a few brave facts, asks more questions,” he said.

Another element of the report caused by the dispute is a reference to the security bulletin – in 2018 is known as a newsletter of the US Federal Aviation Administration (FAA) published by the Federal Aviation Administration (FAA).

This was used for the warning of the aircraft society, which was warned that the operators of the operators of the Boeing 737 model operators were equipped with an ejaculation feature – the transition allows them to be accidentally hit.

At that time, the FAA described it as “rescue concerns”, but it said, “not a dangerous situation, which requires binding movement known as a flight capacity directive.

The operators of a number of different Boeing models, including similar switches, including 787, were advised to implement simple inspections.

The investigation report says India does not implement these inspections – the accident’s wrong switches are asked for assumptions that the accident was caused by an accident.

But In an internal note seen by the BBCThe FAA has repeated its confidence that this issue has not compromised for security.

The sources of engineering said the throttle control module was changed two years ago in the planned plane in the planned plane crashed in the report. This would also be confused to change the cut keys.

According to BJehn Fehrmun, Leeham news, the FAA’s recommendations in the report were “completely irrelevant” in the context of the accident.

Nevertheless, the Civil Aviation Directorate of India asked the operators of all planes covered by the original Bulletin of the FAA on July 21.

The uncertainty of the report for the former accident may be deliberately intentionally to explain to an explanation for the crash for Tim Atkinson.

“The worst reports are written to read” between the lines and if it is here, there is no credit to investigators, “he said.

Meanwhile, those who have been looking for a strong answer to what happened in the 171st flight may have to wait.

The international protocols provide the importance of broadcast the final report during the accident. But in practice, it can take longer.
