Cockpit deepens the audio flight secrecy 171 crashes

The investigators discovered a cold in the preliminary investigation in the preliminary investigation in the preliminary investigation in the Preliminary investigation in the Preliminary investigation in connection with the India’s flight in June 260.

A few seconds later, both 12-year-old Boeing 787 Dreamliner’s fuel-control switches are transferred to the “cut” position, which causes fuel engines to the waste of their fuel and total power. Switching to “Cutting” is usually just a movement after landing.

Cockpit sound recording, because he did not answer the person asking why a pilot asks why he did not answer. The writing does not clarify.

The keys were returned to the normal inflight position from the engine. Another engine was encountered in an engine agreed in the accident, but still did not restore the government.

Air India was busy with air with less than 171, 40 seconds of flight before crashing in a crowded neighborhood Celebrating one of the most suffocating aviation disasters in India in Ahmedabad’s West India.

Investigators test the wreckage and cockpit records to understand what wrong after leaving the flight. Air India flight, FlightHtradar24 went to 625 feet fresh air before losing places in 50 seconds. The 15-page report on Saturday offers early insights.

Investigation – Boeing by Indian government, generates several questions with general electricity, air India, Indian regulators and specialists in the United States and the United Kingdom.

Investigators are designed to prevent random activation of Lever-lock fuel switches – they must be drawn to unlock before flying, the security feature of the 1950s. They are very reliable in accordance with the requirements. Protective protective brackets protect them more than random bumps.

“It is almost impossible to draw a single movement of both switches, and this random placement,” The investigator of Canada-based air crashes, not disclosed, BBC.

This is what causes the weather in the weather.

If one of the pilots was responsible for deliberately, deliberately or not, “asks: why … why … why … Why the Past Airline University’s Former Airline Safarian and Aviation Specialist” Shawn Pruchnicki “Shawn Pruchnicki.

“Was it a consequence of intentional or confusion?

Peter Goelz, a former US NTSB Director, gave a similar part: “The findings are very concerned – a pilot closed the fuel key within the flying seconds.”

“There is more likely to be more likely in the cockpit sound printer than shared.” Why do you cut the keys “as a single note as a single note,” he said.

“New Details Close these valves of someone in this cockpit and why, whose and why? Both switches and then restart within seconds.

Investigators believe in the cockpit voice print – Sounds from pilot miches, radio calls and surrounding cockpit sounds – this is the key to the puzzle.

“They still did not identify the voices. When the sound printer is usually reviewed, people who are familiar with pilots are available to help match the sounds.

In short, investigators are a comprehensive investigation of all communication from the moment a complete cockpit transcript, which is a complete cockpit, labeled speakers, labeled speakers.

It is said that this emphasizes the need for cockpit videos recommended by NTSB. The above look will show whose hand is in the cut key.

Before boarding the 171th flight, both pilots and crew-breathing tests and adapted to fly. The pilots located in Mumbai came to Ahmadabad and adequate the day before the flight.

However, investigators are an interesting point in the report from scratch in what they describe.

In December 2018, the US Federal Aviation Administration, some Boeing 737 fuel control keys were installed in the locking feature of 737 fuel control switches were installed, the Special Hawaiian newsletter (SAI) gave.

Although the issue is noted, a dangerous situation requiring a Hawaol Directive (ad) – the product was not considered a legally valid arrangement to correct the dangerous conditions in the product.

The same Key design is used in the Boeing 787-8 aircraft, including the air in India’s VT-Anb. As SAIB recommends, Air India did not perform the recommended inspections.

Mr. Pruchnicki said he thought there was a problem with fuel control switches.

“What does it mean) with almost a flip, can this transition turn off the engine and close fuel supply?

Others do not believe that this is the main issue.

“I haven’t seemed to give a low profile faa about it.

Kaptan Kishore Chinta, the Old Promotion Bureau (AAIB) of the Plane Crash in the Indian Investigator (AIB), followed the keys due to the problem in the electronic control section of the aircraft.

“Can the fuel cutting switches cause an electronic management unit by the electronic management section without moving the plane by pilot?

The report said fuel samples were “satisfactory” from refueling tanks. Experts suggested the previous fuel pollution as a possible cause of a dual engine failure. Note that no advice was given for Boeing 787 or GE Genx-1B engines, except for the mechanic failures waiting for the investigation.

In addition, the plane placed the RAM Air Turbine (rat) and the failure of the main systems and the failure of the main systems and the “low position” or undoed landing facility was discovered.

The rat operates as a small propeller, an emergency backup, which extends under the bottom of the Boeing 787 Dreamliner. It is automatically placed in flight when both engines lose power or all three hydraulic systems are critical of all three hydraulic systems.

“The placement of the Ram Air Turbine (rat) strongly supports the conclusion that both engines fail,” Mr. Pruchnicki said.

A Boeing 787 pilot explained that the decline gears did not retreat.

“These days, every time I go out in 787, I see the decline-gearing process. When Gear’s handle is withdrawn, 200 feet (60.9m) and the entire gear is about eight seconds, thanks to the high-pressure hydraulic system of the plane.”

The pilot believes that he does not find time to fly.

“When both engines fail, the reaction, reaction continues to be amazed only.

Investigators say the crew is trying to recover, but this happened very quickly.

“The engines were turned off and then retreated.

“However, the right engine was not enough time to withdraw, and the happening was not enough. Both were” to escape “, but he healed and survived, very little, too late.”
