Qantas grounds A380s after Singapore emergency landing

QANTAS are to change engines on two other A380s.

Interesting comment on the BBC news site

Other airlines using Roll-Royce powered A380s have continued to fly them without any major disruption.

Industry expert Sean Maffett suggested that this may be because the engines on the Qantas planes are slightly different.

He told BBC News that they have bespoke electronic controls which allow them to fly in hotter temperatures or at higher altitudes.

This may explain why Qantas has still grounded its flights, he suggests. Rolls-Royce refused to comment.

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

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

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.

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?)

[Kymmy]

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???

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.

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

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

Yet another engine failure on a Qantas A380

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.
