Quoting the West Australian newspaper:-


Flight MH122 was above Derby in remote WA when the pilot made the decision to land due to “technical reasons”, the airline said.

Passengers on board the flight, which departed Sydney at 1.35pm local time have told of their terror, taking to social media to tell how the plane’s crew were “preparing to crash”.
While the above is sure to elicit cries of woe over standards of aviation journalism, the truly frightening thing is that it actually and accurately reflects the current standard of ALL newspaper journalism.

From the ATC tapes linked above, MH122 declared a PAN on descent into ASP.

Here's the classic 'I hoid a bang and I knew we wuz gonna die!' news coverage:


The husband of a passenger onboard a Malaysia Airlines flight forced to divert to Alice Springs says his wife has described the experience as "hell".

Flight MH122 was travelling from Sydney to Kuala Lumpur with 224 passengers onboard this afternoon when one of the Airbus A330-300 plane's engines is believed to have been shut down.

Chin Kanani said his wife became alarmed when she heard a banging sound.

"She said she was on the loo when she started hearing loud banging noises from the right-hand side of the plane and that's when all it started," Mr Kanani said.

"It was like hell this flight and they were told to be ready for an emergency landing."

‘Brace for impact’: Passengers terrified as Malaysia Airlines flight makes emergency landing in Alice Springs

By Sean Davidson
10:28pm Jan 18, 2018

A terrified passenger has told of how she "thought she was going to die" after crew on board a Malaysia Airlines flight told passengers to brace for impact when the plane started vibrating.

Flight MH122, an Airbus A330 heading to Kuala Lumpur from Sydney, was four hours into the flight when a "massive vibration" rocked the plane, forcing it to divert to Alice Springs.

"The lights had just been turned off and everyone was settled in," Donna Edwards, who was travelling to London, told 9news.com.au.

"All of sudden a massive vibration, the whole plane was shaking."

Ms Edwards said passengers were holding hands and bracing for 30 minutes before the crew announced everyone should "brace for impact".

"The fight attendant came on and said the pilot will give a 30-second warning before impact," she said.

"One of the crew stopped near us and one guy said ‘are we crashing or are we landing’.

"The crew member said 'I don't know'.

“We were just bracing for the worst. I thought I was going to die.

"But then 30 minutes later the crew said it was under control."

interesting choice for diversion. Was he running for Melb and had to put her down. Darwin would on the face of it seem the better initial option.

A Twitter report from a pax:

#malaysian airlines #mh122. Emergency landing at Alice Springs. The scariest part was that once the engine started to make a loud disturbing noise, the flight attendants all seemed nervous n clueless. For around 15 mins, there was no announcement.15 mins were as long as 15 hours!
The pilots were probably busy shutting down the engine, assessing the situation and evaluating options.

A timely update like Captain Eric Moody's classic PA would be helpful though:


Ladies and gentlemen, this is your captain speaking. We have a small problem. All four engines have stopped. We are doing our damnedest to get them going again. I trust you are not in too much distress.

megan 18th Jan 2018 11:05

Why? It's miles off track, whereas the Alice is on track, if he's going great circle it would put him 27nm abeam, but I'll assume he was planned overhead on the airway.

Close to Derby when they turned around as shown on Flight Aware.

Derby - Alice ~694nm
Derby - Darwin ~ 516nm

Monsoon season so DRW weather might have been not so good.

I wonder why Broome was discounted?

1a sound asleep 18th Jan 2018 11:36

No pan call until near ASP. Looks like they were heading for MEL and then reality hit. Broome was 100 miles from point of diversion. Why were pax told to brace for impact at FL300 ? :rolleyes:

Ancient Mariner 18th Jan 2018 11:38

Trust me, as SFL, having an engine go bang is no fun. Happened to me, SAS B767 climbing out from Beijing. The aircraft was shaking so bad I expected my fillings to drop out. Then again you, as pax, have no clue what's going on and I fully expected a close encounter with the ragged mountains just below us.
On top of that they would not serve me another whisky while returning to land. Business class and all.

krismiler 18th Jan 2018 11:57

At least he diverted to a suitable airport instead of continuing on like some people have done.

Pom Pax 18th Jan 2018 12:08


Monsoon season so DRW weather might have been not so good.
And the same applies for all of the Western Australian coastal airports.
However all of central Australia virtually cloud free.

RAT 5 18th Jan 2018 12:55

Ladies and gentlemen, this is your captain speaking. We have a small problem. All four engines have stopped. We are doing our damnedest to get them going again. I trust you are not in too much distress.

Should be on all command courses. I found there was so little guidance of suitable PA's in NNC's. Given the young age of some who might have to make one..........some help to keep the situation calm 'back there' IMHO is most welcome.

I'm not familiar with this region, or the airports they chose, but, as a generalism, the closest suitable may not be the nearest; in that, by the time you've completed your analysis, executed a checklist or 2, decided where to go reference weather and facilities and LDA, dug out the charts, planned the descent & approach, briefed all who need to be, you might have used up more time than a normal 20-25 minute descent. I hear some people say that you should drop into the airfield nearest underneath you, but if you do and then spend 10 mins holding, to finish up, you could have gone further to a more familiar/convenient/suitable airport with a full defence in place: it might even be your departure airport.

Why would they be heading for Melbourne?

Exactly.

I think it's because the PPRune experts have determined so. The evidence supporting this, however, is rather scant.

Same same the nonsense above re bracing at FL300. Evidence? Oh, a media report about what passenger said. Must be fact then. PPRune has spoken. Not even 24 hours later.

Troubling, isn't it?

As for AS vs DN: I haven't even bothered to check old TAF's but can almost guarantee there would have been TS all over DN. Sounds like AS was a very smart choice by a couple of PROFESSIONAL pilots flying a twin with OEI.

wiggy 18th Jan 2018 17:31

+lots to many of the above comments.

Broome may not have been an authorised airfield for the type involved..we fly over that part of the world in a big twin and it is certainly not authorised for us...(and yes, I know that consideration goes out of the window if the fit has definitely hit the san such as a fire and/or smoke.), Darwin is a way off and may have had weather issues....The Alice OTOH may have been the best fit given circumstances (which we won’t get from flight radar and/or the Twitter sphere).

Says it was probably "an engine stall"

Surprised he didn’t suggest they could have bump-started, given they had sufficient altitude then...

Subsequently, on the TV chat show circuit, Captain Eric Moody said “I’d done some gliding in the Air Training Corps about thirty years ago, but this was the first serious gliding I have done since!”

Technical reasons
 
With airlines making statements like this "Malaysia Airlines' flight MH122/ 18 January 2018 from Sydney to Kuala Lumpur has been diverted to Alice Springs due to technical reasons" it is hardly surprising that passengers get scared and media get it wrong. Maybe advising passengers and future passengers that shutting down one engine and making a safe landing is something that pilots are trained for would be more informative than just keeping everyone in the dark with "technical reasons".

SPOT ON! Its the deception and not being told that pax hate and will use against an airline. "Operational reasons" and "technical issues" are basically like "cover up" or "we dont want to tell the truth"

If you ask anyone who was actually there , that was about Eric Moodys contribution to the entire thing .

Not a hero ......not a clue .....allegedly.

Isn't "engine stall" a generic term for something caused by a disruption of airflow through the engine (for whatever reason)? Without details of what actually caused the problem, how can you say it wasn't a stall?

krismiler 18th Jan 2018 23:09

When Emirates crashed a B777 during a botched go around in Dubai, they described it as "an operational event".

jack11111 18th Jan 2018 23:28

Declaring a "technical issues" to me is such tosh when really you should say: "One engine shut-down due to an abundance of caution."

Technical issues is just weaselly, airline speak.

Passenger claims: "Passengers on board the flight, which departed Sydney at 1.35pm local time have told of their terror, taking to social media to tell how the plane’s crew were “preparing to crash”.

Mr Wolton said while it was a frightening experience, it proved aircraft can fly safely with only one engine.

We really need to find higher quality SLF.

"The passengers are revolting, Captain" They certainly ARE.

tartare 18th Jan 2018 23:35

...or a major malfunction? :E
Seriously though - imagine what it's like to be SLF, and hear a loud bang then experience intense vibration.
You'd be shitting yourself.
Hell - I'm a pilot and I'd be shitting myself (jeez, that sounded like a blade cutting loose, did it miss the cabin, take out any hydraulic lines, is the whole disk next?).

"Ladies and gentlemen, obviously we have a problem with one engine - the plane can fly perfectly well without it running. We're going to shut it down and quickly drop to a lower altitude as a precaution, please ensure you're seated with your seatbelts firmly fastened...."

Sunfish 18th Jan 2018 23:36

Part of the reasoning will include proximity to maintenance facilities.

Global Aviator 18th Jan 2018 23:41

People fast to kick the feet into MH, as as been said above it appears a solid decision to divert to a pretty much guaranteed CAVOK airport. International airport, facilities, no doubt also on most airlines approved airports. It’s a no brained really.

Fly the plane deal with the issues divert to suitable airport. Obviously not thinking but it’s not a home base for engineering.

So far to me it’s nice work Capt and crew.

In a twin, that should have nothing to do with it.

Miraz 19th Jan 2018 00:30

Diverting to ASP seems like a sensible call - it's been on the ground for several hours, and not a single PPRUNE post with any photos of damaged components or claims of first hand knowledge. :ok:

Octane 19th Jan 2018 01:15

Is Alice Springs an international airport?!

Lookleft 19th Jan 2018 01:51


Part of the reasoning will include proximity to maintenance facilities.
What maintenance facilities for an A330 do you think exist in AS Sunfish? I would suggest that the crew diverted to AS because it was closest suitable airport due to its ATC and passenger facilities, the weather and its proximity to their position.

Job well done from where I sit.

Gegenbeispiel 19th Jan 2018 02:27

Continue on 1 engine over water ???

Continuing out over water on one engine when the problem occurred over land would have seemed somewhat insane - and contrary to procedures.

Sounds like a job well done by the flight crew. The brace position call may have been airline's procedure for any landing with engine problems, same as having fire appliances rolling.

WingNut60 19th Jan 2018 02:39

Cannot be pleasant sitting watching a windmilling engine banging away outside your window.

This incident seems to bear some similarity to the Air Asia Airbus A330, (9M-XXE) incident near Carnarvon, Western Australia, on 25 June 2017.

Final report for that event due out soon. I'm eager to see what ATSB has to say about that turn-back.

CurtainTwitcher 19th Jan 2018 02:40

It will be a masterful work of diplomacy...

mrdeux 19th Jan 2018 02:51

Darwin had thunderstorms. Alice, Learmonth both ok. Alice is a bit further than Learmonth, but not hugely.

What about Curtain? I'm sure the pax would love a night in Hedland. And it was less than 100 miles away.

WingNut60 19th Jan 2018 03:00

Emergency services also come into the equation. Not a lot at Curtin nor Learmonth.
You'd probably do better at Karratha. Might be a bit short for an ailing A330.

Port Hedland however does have Immigration available from time to time.


What about Curtain? I'm sure the pax would love a night in Hedland. And it was less than 100 miles away.
Not sure about your geography here. More like 300+.
And Curtin was pretty much straight down.

ACMS 19th Jan 2018 03:35

Well there’s LAND ASAP in Red and LAND ASAP in Amber.

Up to the CN and crew to decide which one they fit into and therefore which place they “SELECT” to go based on the information they have at their disposal AT THE TIME isn’t it.

( My company certainly don’t have any charts for Curtain )

You Monday morning quarterbacks need to wind it in a bit.

They all walked away and the operation was safe.
