There was an 'oil' issue with Trent 700 some years ago.

I wonder which way its wheels would have rotated had it landed on a conveyor belt...

The engines are virtually brand new, so what is that claim, 'years ago',? Also another thread exists regarding this..

The Trent 700 has been in service for 15 years, and the article above relates to a failure involving one seven years ago. The Trent 900, the engine fitted to VH-OQA, is related to the 700.

Would you care to take your own advice and not post unless you have something to add?

Can you provide evidence to support this?

I've seen documentary evidince to that these engines are not 15 years old. So all the information above is unrelated to the latest failure.

Looks like a power turbine has come apart, rear of engine, hot area lots of centrifugal force lucky the bits didn't hit a fuel tank or penetrate the passenger cabin.

If that's not evidence enough for you, I don't know what will be.

Micky has been proven wrong again so wont reply

An engine is 'related' to a different engine, so splitting hairs really. So when I say the 900 engine isn't 15 years old, then it isn't, whereas the engine that it 'relates' to, is.

Any modern day engine is 'related' to the origional engine by Benz, but they are totally different beings, but work on the same principle. What a petty point. And then a link to someones blog, that refers to a different engine again, regarding a different fault, that could cause an oil fire (not the case here), or an engine shutdown (again not the case), try engine blow up. So no, I'm not wrong with anything I said.

You are very, very dense.

Could be significant pix. Hefty lump of disc allegedly recovered on Batam from A380 engine wreckage.
Source flightglobal.com

...ENGINEERS say an intermediate pressure turbine disc in the No 2 engine of QF32 failed, triggering the explosion that ripped through the engine casing of the A380.

The explosion damaged the wing and left a trail of wreckage across the Indonesian island of Batam.

Investigators do not yet know why the disc failed, as the superjumbo carrying 440 passengers and 26 crew climbed after leaving Changi Airport in Singapore on Thursday. But they are examining certain scenarios that could have caused the problem. These include an oil fire in the bearing compartment, blocked cooling tubes or a bearing failure...

For anyone interested here are the parts and their relationship which you'll likely hear / see bandied about.
