Qantas grounds A380s after Singapore emergency landing
 

I see one of these super jumbo's landing at Manchester Airport each day . Glad they landed safely

Re: Qantas grounds A380s after Singapore emergency landing
 

It'll be interesting as to what happened with the trent 900 (I presume Quantas is using them)

Re: Qantas grounds A380s after Singapore emergency landing
 

That is one quiet engine. We hear the jumbo's landing all the time but the Airbus 380 is very much the quieter plane of the two.

Used to live at Heathrow in the early 2000s, Now concord was the one to make the house shake..

Just to confirm that only not all A380 aircraft use Rolls-Royce engines. These have been chosen by Lufthansa and Singapore Airlines, as well as by Qantas.

A380s flown by Emirates and Air France are instead kitted out by the Engine Alliance, a 50/50 joint venture between GE Aircraft Engines and Pratt & Whitney.

Re: Qantas grounds A380s after Singapore emergency landing
 

Im supposed to be flying on a 380 (Emirates) a week on Saturday. I'm ok about the whole thing but my wife, who is a nervous flyer, has already started to panick.

Re: Qantas grounds A380s after Singapore emergency landing
 

As Kymmy says, different engine.

Re: Qantas grounds A380s after Singapore emergency landing
 

I saw a programme, probably on Discovery, not that long ago that showed the development, testing and manufacture process of the Trent engines. Not only do they consider the reliability and efficiency, but considerable effort is taken over the safety of them should the worst happen. That the plane flew on fewer engines with no apparent significant issues, despite the visible damage is a testament to the safety standards of that design process.

Even so I suspect there will be many in the industry anxiously awaiting the findings of what went wrong.

Re: Qantas grounds A380s after Singapore emergency landing
 

Oh, there will. I have friends who advise and work with customers on safety in various situations. Customers including airliner manufacturers and airlines. I have been told on many occasions (and been shown video as proof) that airline safety is taken *very* seriously.

After all, if a plane goes down, with the loss of hundreds of lives, and there is any question whether the airline was negligent or even responsible, then the airline can (and probably will) be bankrupted by the accident.

Look at Pan Am.

Re: Concorde. Rather interestingly, from what I was told, the writing for Concorde was effectively on the wall before the disaster that was blamed for it's retirement. Apparently the problem was that it's safety systems, while legal in the 60s and quite effective in the event of disaster, were below legal minimum requirements after 2000.

The Airlines did discuss upgrading them, but it would have cost a lot of money to upgrade each plane, and with airlines like Ryan Air, EasyJet and BMI doing their utmost to drive ticket prices down, it was felt that BA and Air France would not be able to recoup the money invested in upgrading the safety systems.

Re: Qantas grounds A380s after Singapore emergency landing
 

Well in 90 years of flying Quantas have never had jet fatalities.

In 1951 7 where killed in a prop crash (59 years ago)

Re: Qantas grounds A380s after Singapore emergency landing
 

Looking at the damage I'd suggest a turbine blade failure (either an internal component has worked/blown loose and impacted the turbine blades or there's been a blade failure due to a manufacturing problem.. This is supported by where the damage occured on the wing and also the rear casings that have been blown off

The turbine blades are at the rear of the engine which the thrust from the compressed air/fuel mixture igniting acts upon to turn the more forward compressor and fan blades..

Re: Qantas grounds A380s after Singapore emergency landing
 

Apparently there was an inspection directive on the Intermediate Pressure Turbine shaft which was showing excessive wear, whether this had something to do with it or not...

Second failure of a Trent 900 though, (not counting the runaway condition engine one had after landing where they had to use a water jet to force it to blow on this landing.)

Seems to be the same problem they are having with the Trent 1000 which is intended for the 787 Dreamliner. The test engine failed on the bed after a problem with the IPT Shaft...

This totals 6 problems I can find with the A380s in the past 2 years, 1 fuelling fault, 2 engine failures (All with Trent 900s) 2 incidences of Nose gear steering failure (on the same aircraft that just had to emergency land) and a heavy landing blowing out tyres.

Of 80 Trent 900s in service, 3 have failed, not the best record is it?

Re: Qantas grounds A380s after Singapore emergency landing
 

Some good pictures and discussion here...

Re: Qantas grounds A380s after Singapore emergency landing
 

And also a lot of uninformed dross by armchair "experts" by reading a couple of pages.

Re: Qantas grounds A380s after Singapore emergency landing
 

well its not just the Airbus A380 thats having problems with Quantas this time.... http://www.bbc.co.uk/news/world-asia-pacific-11702365 boeing 737-400 similar issues.

Re: Qantas grounds A380s after Singapore emergency landing
 

You mean a 747-400 ??

Re: Qantas grounds A380s after Singapore emergency landing
 

QANTAS are to change engines on two other A380s.

Re: Qantas grounds A380s after Singapore emergency landing
 

Interesting comment on the BBC news site

Re: Qantas grounds A380s after Singapore emergency landing
 

Apparently they're 'chipped' to a higher thrust output than Lufthansa or Singapore Airlines A380 engines:

Re: Qantas grounds A380s after Singapore emergency landing
 

Aparently RR have agreed to replace all the engines ,repair the old ones ,then swap them back ,gonna cost a fortune link

More pictures (some duplicates of the above) and analysis of the damage here.

Re: Qantas grounds A380s after Singapore emergency landing
 

Something is not right here. This engine flew from LHR to Singapore without any problems then all of a sudden it left Singapore and blew.

There's something not adding up here.:confused::confused::confused:

Re: Qantas grounds A380s after Singapore emergency landing
 

funnly someone said something simmilar on pprune (website for professional pilots and CC) and was quite logically rebuffed.

Say you had a car that had just gonefor along drive with no problems you stop to get some fuel and a mile or 2 down the road the engine blows up, was it the peteral stations fault (possiable but HIGHLY unlikly) or just the culmitive affect of all your traveling (MUCH MUCH more likly).

You also have to remember takeoff is by FAR the most stresfull time on an engine so if theres something wrong with then engine itself (such as an oil leak) its MUCH more likly to cause a siginificant problem on takeoff then steady croose(sp?)

Re: Qantas grounds A380s after Singapore emergency landing
 

I'd more suggest the cooling and pooling effect, running the engine is fine with the fault, let it stand for a short time and the leaks pool and the components cool and contract.. start her up again and BANG a few miles down the road

PS..croose = cruise???

Re: Qantas grounds A380s after Singapore emergency landing
 

Indeed. And:

funnly = funnily
simmilar = similar
gonefor along = gone for a long
peteral = petrol
stations = station's
possiable = possible
culmitive = cumulative
traveling = travelling
takeoff = take off
stresfull = stressful
theres = there's
its = it's
likly = likely
siginificant = significant

Obviously you've never owned a car.

Re: Qantas grounds A380s after Singapore emergency landing
 

Could have been worse I suppose, it could have been txt spk :p:

Re: Qantas grounds A380s after Singapore emergency landing
 

Apparently the problem was caused by a misaligned counter bore on an oil feed pipe.

Yet another engine failure on a Qantas A380

http://www.bbc.co.uk/news/business-15587519

Re: Qantas grounds A380s after Singapore emergency landing
 

Plane engines get shut down all the time and nobody reads about it unless its a new plane or somebody famous in onboard.

IMHO it's a non story.

Re: Qantas grounds A380s after Singapore emergency landing
 

thats true but sometimes risks taken too far on grounds finance. Did Qantas really need the engines tuned differently would without tuning would they been fine.

Few years back from mallorca we had electric fault in 1 engine the tour operator decided to jump start the engine down the runway:shocked:. Pilot said its like jump starting a car yes right thats convincing cars dont fall out sky.

As we passed point no return no sign it kicking in we was commited to take off mountains ahead it suddenly spluttered into life but not enough speed.

As we went in the air we started falling as clearly we was stalling with lack airspeed. Screams everywhere as people thought we going down but then it kicked in full speed we climbed again.

Never been scared all my life flying that flight as we goto manchester loads of fire engines followed us. Probably as this engine was still worry.

I believe the procedure banned as its been tried another 2 times and they crashed on takeoff.
