China Eastern: Plane carrying 132 people crashes in Guangxi hills
Published15 minutes ago
A Chinese passenger plane with 132 people on board has crashed in a forested hillside in southern China.
The China Eastern Airlines Boeing 737-800 was flying from Kunming to Guangzhou when it plunged to earth in Guangxi province and caught fire.
The number of casualties and reason for the crash are not yet known. Rescuers have seen no signs of survivors.
Chinese airlines generally have a good safety record - the last major accident took place 12 years ago
The crash has caused shock in China where President Xi Jinping has ordered an immediate investigation to determine the cause. China Eastern Airlines has reportedly grounded all its 737s.
Flight tracking data suggested the plane lost height rapidly from its cruising altitude before plummeting to the ground.

Plane with more than 130 passengers crashed in China, images seem to indicate that plane crashed perpendicularly down
In the southwest of China, a plane with more than 130 passengers crashed. That reports the Chinese state television. It is a Boeing 737 of the company China Eastern. Rescue workers have found no indications that passengers are still alive. Unconfirmed images from a surveillance camera show how the device crashed perpendicularly downwards.

The accident happened in a remote, hilly area near the city of Wuzhou in the Guangxi region. According to local media, it is flight MU5735. It had taken off shortly after 1 p.m. local time in Kunming and on its way to Guangzhou, about 1,300 kilometers away. At 2.19 pm local time (7.19 am Belgian time) the plane suddenly dropped. Two minutes later, contact was lost.

 

Data from FlightRadar24 shows that the six-year-old plane took a nosedive. The cause of the crash is not yet known, but there is plenty of speculation. "Even if both engines of the Boeing 737 had failed at the same time, it would be impossible to crash at such a speed because the plane could still float for a long time," an expert told state media.

In videos that local residents made and circulated on social media, a thick cloud of smoke can be seen. The debris is widely separated. Certain images also show how the plane almost crashed upside down, but those images have not yet been verified. Local residents report that there is debris everywhere and clothes hanging in the trees.

After the crash, a forest fire started over an area of four hectares, but it was later extinguished. The airline's website was black and white, as a sign of respect for the victims. A special telephone number has been opened for relatives of the occupants. China Eastern Airlines is grounding all Boeing 737s in its fleet for the time being.

 

Chinese President Xi Jinping said in an initial reaction that he was "shocked". He wants to do everything in his power to find out the cause of the accident as quickly as possible.

There would have been 132 people on board, including nine crew members. In initial reports, there were 133 passengers.

The last serious plane crash in China happened in August 2010 in Yichun in Heilongjiang province. In an emergency landing of a Henan Airlines plane, 44 passengers were killed, 52 others survived the incident.

The vertical dive as claimed to be this aircraft leaves no doubt as to the terror involved.

For sure the answer to genuine cause needs to be found !

Or the same computer fault as the one before who pushed the nose down whiteout possible control to bring up again .....?

No, this one was not a 737 MAX.

Yes. Hopefully the voice and flight data recorders are found and in readable condition to shed light on the reasons for this accident.

 

RIP to the crew and Pax

MCAS is only on the 737 MAX series, while this was 737-800 NG.

 

It's not easy to nose-dive a plane. Though there were cases with older 737s where rudder did a hard-over and sent plane into an uncontrolled roll. It would also be possible if neither of pilots noticed the bank until it rolled over; or stalled the plane. Or if there was an in-air break-up of the plane, which I guess would be quickly determined, if any of the parts are very far from the main site. Difficult to see from that video, but it seemed at least fuselage was in one piece. The blob on the screen isn't clear enough to show whether wings, elevators and rudder are attached. But modern planes just don't have parts, considered to be strongest part of the assembly, falling off.

 

I'm really curious to learn what happened.

 

Unfortunately, this will bring yet another black spot on the reputation of otherwise very popular and reliable Boeing 737 series. Certainly doesn't help after MAX fiasco.

That's a very different beast to B737 that the story is about.

yes a big beast comparing ..... but it's those computer system i worry about .....,

 

as once i saw a YouTube about that big airplane cemetery in some dessert part in USA , one of those demolisher claiming.. while taking such a flight computer out ....to the camera ..... "those fancy pilots think THEY fly the plane...?..... no-way this boxes  doing that ! "  (joking way said by him of course .... but a kind of truth is in it in this modern digital world ????

A fairly large piece of the lower wing skin and a piece of (maybe) rudder have been found away from the main site, so in-air break-up is a possibility. The initial data looks like they managed to pull it up slightly for a few seconds before it hit.

If we ignore MCAS, in the regard of automation, Airbus is a clear winner, overriding the pilot, where on Boeing pilot has final say. Both take a lot of work off the pilots through automation and can address sticky situations. It's just about the mentality of the engineering teams where Europeans prefer automation, and Americans some manual controls.

Could be, although if the plane is nose-diving, it would also likely exceed maximum speed it's built for, which could also (and generally does) lead to in-air break-up. Obviously the difference is whether the parts are found a few km from site (broke up while diving) or many km away (where break-up could be the reason for dive). If they could pull the nose up before hitting the ground, then elevators and wings had to be attached. And you can't control it without rudder either, it would go into spin, so to lift up, all bits of the plane would have to have been attached... if back broke off, then front would have been heavier and would dive even steeper...

 

Excited to learn what happened.

I doubt you know what you are talking about.

[ozfarang]

One of the data recorders has been found.

 

Hope the data is readable

[EricTh]

Shouldn't the Boeing protects itself automatically , a sort of built-in mechanism?

 

Is this a terrorist attack?

Just read through this:

https://avherald.com/h?article=4f64be2f&opt=0

 

It remains a mystery until the flight data recorders are found and give a clue.

There was no emergency call or reports of difficulties!

Air traffic control noticed the steep descend and tried to contact the crew several times without response.

Very unusual!

Even a complete loss of all engines and electric power would not result in a drop like a stone.

Not surprised. Pilots follow "Aviate, navigate, communicate" rule. Where flying the plane, knowing where you are and where you can go is far more important than letting someone know about it, who can't help you in anything in case of emergency. So it is not unusual that pilots don't respond when in critical situation.

[ozfarang]

Both the flight data recorders are now in the USA and the NTSB will be working on downloading the data, so should have some idea why the aircraft crashed in one or two weeks.

and on 03/04/2022, another 737-800 had this problem:

the coincidence is troubling.

the incident superficially looks pretty similar.

 

could a buggy software update have caused this?
