Boeing 737 passenger jet carrying 133 crashes in rural China

A Boeing 737 carrying 132 people has plummeted 30,000ft to the ground before bursting into flames in a remote Chinese mountain range – with no sign of survivors.

The China Eastern Airlines flight nosedived before smashing into the hillside and erupting in a huge fireball near the city of Wuzhou in Teng county in the southern province of Guangxi.

A rescue official reportedly said the plane had completely disintegrated while a fire sparked by the crash ripped through bamboo and trees before being put out.

Horrifying CCTV footage emerged on social media supposedly showing the jet racing vertically towards the ground in the moments before the smash.

President Xi Jinping said that he was ‘shocked’ by the incident and immediately ordered an investigation into the cause.

It is not yet clear what forced the sudden dip and crash, but aviation experts told MailOnline it may have been ‘a loss of control event, possibly following a high altitude stall of the aircraft’ or a sensory failure in the cockpit.

The plane, flight number MU5735 from Kunming to Guangzhou, is believed to be a Boeing 737-89P, which is not part of the MAX series that has been dogged by problems in recent years.

The crash will renew calls for China to make its aviation safety record – which is considered good but allegedly sees an underreporting of safety lapses – more transparent.

China’s Civil Aviation Administration of China (CAAC) said the aircraft lost contact over the city of Wuzhou.

It had 123 passengers and nine crew on board. State media said earlier there were 133 people on board.

The CAAC said in a statement: ‘The CAAC has activated the emergency mechanism and sent a working group to the scene.’

The Aviation Safety Network said: ‘We are following multiple unconfirmed reports about a possible accident involving China Eastern Airlines flight #MU5735 a Boeing 737-89P (B-1791) en route from Kunming to Guangzhou, China.’

President Xi said: ‘We are shocked to learn of the China Eastern MU5735 accident.

He also called for ‘all efforts’ towards the rescue and to find out the ’cause of the accident as soon as possible’.

One villager told a local news site the plane involved in the crash had ‘completely fallen apart’ and he had seen forest destroyed by the fire caused by the crash.

A local official added: ‘The exact location of the accident was Langnan township in Teng county.’

The flight departed the southwestern city of Kunming at 1.11pm (5.11pm GMT), FlightRadar24 data showed.

But tracking ended at 2.22pm (6.22am GMT) at an altitude of 3,225 feet with a speed of 376 knots.

The plane had been cruising at an altitude 29,100 feet at 6.20am GMT, according to FlightRadar24 data.

Just over two minutes and 15 seconds later, the next available data showed it had descended to 9,075 feet. In another 20 seconds, its last tracked altitude was 3,225 feet.

It had been due to land in Guangzhou, on the east coast, at 3.05pm (7.05am GMT).

A huge force of 23 fire trucks and 117 rescuers were said to have been deployed to help in the search.

Shares of Boeing Co were down 6.4 per cent at $180.44 in premarket trade.

Boeing did not immediately respond to a request for comment.

The website of China Eastern Airlines was later presented in black and white, which airlines do in response to a crash as a sign of respect for the assumed victims.

Arthur Rowe, specialist fellow in gas turbine performance and operability centre for propulsion engineering at Cranfield University, told MailOnline: ‘It looks most likely a loss of control event, possibly following a high altitude stall of the aircraft.

‘As usual there are multiple possible causes. Jammed or unresponsive control surfaces, especially on the tail are one.

‘An inappropriate combination of autopilot settings is another – I’m not familiar with the details of this aircraft’s flight controls though.

‘Sabotage, although that’s probably unlikely on a domestic Chinese flight given the Covid restrictions on entering the country.

‘It’s unlikely to be engine related as aircraft can fly perfectly well with no engine power – for a limited time obviously.’

Professor Bharath Ganapathisubramani, from Southampton University’s engineering and physical sciences department added: ‘Having looked at this and discussed with colleagues, we think that it is far too early to even speculate on possible causes.

‘If the Flight Data Recorder and slash or the Cockpit Voice Recorder are found and are in a usable condition, we should know much more in a few months’ time, with a final, definitive answer to what caused the tragedy likely to emerge in a year or so – based on the typical timelines of such events.’

Tao Yang, associate professor in engineering at Nottingham University, said: ‘The plane was completely out of control and at this stage it is very difficult to say what has happened. However, most of the aeroplane accidents are related to sensors failure – ice protection fails.’ 

Aviation data provider OAG said this month state-owned China Eastern Airlines was the world’s sixth-largest by scheduled weekly seat capacity and the biggest in China.

It has had a relatively strong performance in the domestic market during the coronavirus pandemic despite tight curbs on international flights, OAG said.

It is one of China’s top three airlines, operating scores of domestic and international routes serving 248 destinations.

The aircraft was delivered to China Eastern from Boeing in June 2015 and had been flying for over six years.

The twin-engine, single aisle Boeing 737 is one of the world’s most popular planes for short and medium-haul flights.

China Eastern operates multiple versions of the common aircraft, including the 737-800 and the 737 Max. The 737 Max version was grounded worldwide after two fatal crashes.

China’s aviation regulator cleared that plane to return to service late last year, making the country the last major market to do so.

The popular 737-800 variant has a maximum seating capacity of 189 and is equipped with CFM-56 engine, according to the planemaker’s website.

The engines are made by a joint venture between General Electric Co and France’s Safran SA.

The safety record of China’s airline industry has been among the best in the world in the past decade.

But it is also less transparent than in countries like the US and Australia where regulators release detailed reports on non-fatal incidents, said Greg Waldron, Asia managing editor at industry publication Flightglobal.

‘This makes it hard to get a sense of the true situation with Chinese carriers,’ he said. ‘There have been concerns that there is some underreporting of safety lapses on the mainland.’

According to Aviation Safety Network, China’s last fatal jet accident was in 2010, when 44 of 96 people were killed when an Embraer E-190 regional jet flown by Henan Airlines crashed on approach to Yichun airport in low visibility.

The 737-800 model that crashed today has a good safety record and is the predecessor to the 737 MAX model that has been grounded in China for more than three years following fatal crashes in 2018 in Indonesia and 2019 in Ethiopia.

Boeing was forced to stop the 737 Max after the crashes in Indonesia and Ethiopia happened less than six months apart.

The first disaster happened October 29, 2018, when a Max flying as Lion Air flight JT 610 fell into the Java Sea 15 minutes after taking off from Jakarta.

All 189 aboard the plane died, including 180 Indonesians, one Italian and one Indian. The second was on March 10, 2019, when Ethiopian Airlines slight ET 302 took off from the Ethiopian capital and crashed. 

All 157 people onboard the plane died. The plane was grounded around the world and thousands of holidaymakers and travellers missed their flights.

Boeing reported on July 14, 2019, that customers cancelled orders for 60 of the grounded 737 MAX jets in June.  The aircraft maker removed another 123 planes from its backlog over doubts that the deals will be completed.

In 1992, a China Southern 737-300 jet flying from Guangzhou to Guilin crashed on descent, killing all 141 people on board, according to Aviation Safety Network.

Most of the passengers onboard the Malaysia Airlines Flight MH370, which disappeared in March 2014 en route from Kuala Lumpur to Beijing, were from China.
