What could have caused Air India plane to crash in 30 seconds?

What exactly happened to the AI171 flight between Ahmedabad and London Gatwick on Thursday afternoon, only a detailed investigation, but moments after take-off can be most challenging in the aviation.

Indian investigators will join the US experts in the UK in the coming days, because the authorities are trying to determine what was created soon after take-off just 1.5 km from the beach at Sardar Vallabhbhai Patel International Airport.

It means the first time that 787-8 Dreamliner suffered a fatal decline because he entered commercial service in 2011. years. The catastrophe on Thursday was entered on Thursday 241 people in the field and more on the field.

The BBC has spoken to Aviation Experts as well as pilots Based in India – Anonymity – Who Regularly Fly 787-8s Out of India’s International Airports to find out What Factors Might Have Caused The Plane To Slam Into Residential Buildings In The Heart Of Ahmedabad Just Moments Into Its Flight.

787-8 Dreamliner flew Captain Sumeet Sabharval and his co-pilot Clive kunar. The two were highly experienced, with more than 9,000 combined flying hours. Г. Sabharval earned exceeding 22 years of expertise as a commercial airline pilot.

The plane was transported 242 people as it was on Thursday afternoon in the afternoon in Ahmedabad International Airport. Jet took off at 13:39 local time (08:09 GMT), the Air India operator said.

The Indian Internal Affairs Minister Amit Shah said that the plane carries 100 tonnes of fuel – practically full load – as he climbed from Ahmedabad.

Almost immediately after the download, the cockpit gave a call in Max, the Indian air regulator said. After that, there was no answer to the answer after that. It is unclear what he asked for a call for Maidai, but the only summer summer told Indian media that he heard a loud bang as the plane struggled to arrive at the height.

The recordings certified by the BBC Verify then showed that the aircraft was flying low before it seems housing neighborhood. The final removable data showed that the plane reached a height of 625ft (190m). It continues to go down and becomes tinted trees and buildings, before a big explosion appears on the horizon.

“There was no time to react if they lose the engines,” said one pilot. CCTV shots watching the BBC confirms that the aircraft was in the air for 30 seconds.

The plane crashed in a residential area, with pictures showing housing blocks severely damaged in a densely built area that included hospitals and official buildings.

It is almost impossible to definitely determine what caused a disaster based on the aircraft aircraft.

In the coming days, a complex investigation involving the black box of the aircraft – which will start flight data – and will begin the tests of waste. But videos that appeared show that the plane is fighting to raise from the ground, seemingly due to lacking pushing or power.

One cause, which some experts, speculated the possibility of extremely infrequent draping of double engines. The questions are set whether the plane had its RAM air turbine (rat), an emergency emptiness that begins when the main motors do not create strength for essential systems.

Double engine failure are almost unheard of, and the most prominent example “Miracle on Hudson” lost both engines at the moment of bird strike after taking off from New York Airport Laguardia, but it trusted security.

One senior pilot told the BBC to make double engine failure to produce fuel or clogging pollution. The aircraft engines rely on a precise fuel measurement system – if this system is blocked, fuel can be found and motor shutdown.

Marco Chan, former pilot, said the BBC confirms that there is no evidence that would suggest a double engine interest based on available recordings.

Mohan Ranganathan, an airplane expert, told the BBC that the BBC would not be a “very, very rare incident” BBC.

Motor Motor Ge Aerospace said that the team sent to India to help in the investigation, while Boeing said he was offering his full airline support.

Another possibility that some experts set in India’s bird strike.

They come when the plane crashes with a bird and can be extremely dangerous to the airplanes. In serious cases, motors can lose power if they suck the bird, as it happened Air Air Disaster of South Korea Last year, 179 people killed.

Experts and pilots familiarize with Ahmedabad Airport told BBC that “infamous for birds”.

“They’re always around,” says G. Ranganathan, echoing what at least three Indian pilots who flew from the airport and the airport said from the BBC.

The State Gujarat, where is Ahmedabad, reported 462 incident for birds in five years, and most appear at Ahmedabad Airport, according to the Ministry of Civil Aviation, which were submitted in parliament in 2023. years. Years.

The time of India reports in September 2023. provided data on the airport by stating 38 birds in 2022-23 in Ahmedabad, and 35% increases in the previous 12 months.

In the case of 2009. year, Jato Galebova swallowed at 2,700ft – more than four times more than flight Air India. In this case, Indian pilots did not even have a height for maneuvering.

However, the higher pilot said that the hit bird was rarely catastrophic “unless it affects both engines”.

Three experts who talked to the BBC who verified that the disaster might have reached the flap, while the elevated planes were not extended during take-off – although other pilots and analysts were caused.

The conclusion play a vital role during take-off, helping the aircraft to create maximum lifting at lower speeds.

If they are not properly expanded, fully loaded passengers, heavy fuel for long pull-out and fights for hot conditions – will fight for lifting.

In Ahmedabad, where temperatures were approximately 40 ° C (104F) on Thursday, the thursday would require larger switching settings and a higher engine thrust, one pilot BBC said. In such conditions, even a small configuration error can have catastrophic consequences.

CCTV shots who appeared late Thursday afternoon showed the plane to take off Ahmedabad, struggling to achieve an altitude, and then slowly down before falling.

But rolling the roll with dragged flaps would run warnings with the 787 configuration warning system, warning on the flight crew into an unsafe configuration, according to a BBC pilot.

Former pilot, G. Chan said the BBC was to check that the recording so far is too crooked to determine whether the squattered are extended, but said that such an error will be “very unusual”.

“The flaps place the pilots themselves, before take-off, and there are several checklists and procedures for verification of the setting,” G. said. Chan. “That would point out a potential human error if the flaps are not properly placed.”
