And Qantas is going to sue  Rolls Royce too for it....

And this shouldn't be just limited to Qantas, either.

All but 2 carriers use the Trent 9000s on their A380s, making them all susceptible to this. So shouldn't the ATSB have issued the warning to all of those carriers as well, or is it that they are only concerned about the ones that fly to Australia? In short, SIA should be part of this, too.

"On Dec 2nd 2010 the ATSB released a safety recommendation to Rolls Royce demanding RR should address a safety issue with the manufacturing process of stub pipes, that were identified with an axial misalignment of an area of counter-boring within the inner diameter of the stub pipe leading to a localized thinning of the pipe wall on one side. The ATSB reported, that fatigue cracking had been discovered within a stub pipe (see picture below) feeding oil into the HP/IP (high pressue/intermediate pressure) bearing structure. While investigation of the engine failure is continuing it has been identified that the leakage of oil into the HP/IP bearing structure buffer space and a subsequent oil fire within that area was central to the engine failure and liberation of the IP turbine disk. The area of fatigue cracking was associated with the area of pipe wall thinning."
