More updates:

"Airbus later reported, that the aircraft sustained wiring cuts, the loss of the green hydraulic system and some structural damage as result of the #2 engine uncontained failure. The crew maintained control of the aircraft throughout the flight with autopilot being engaged until 700 feet radar altitude on approach to Singapore, engines #1, #3 and #4 were manually controlled until landing. The landing was done with flaps configuration 3 due to slats being unavailable. The aircraft landed 100 minutes after the engine failure, following the landing engine #1 could not be shut down due to wiring damage which prevented the LP and HP valves to be closed."

Updated article also contains new pics and graphics towards the bottom showing debris plots and flight track.

"On Nov 17th the ATSB reported, that the engine has been removed from the aircraft (see photos below) and is now being dismantled. The low pressure turbine has already been removed to allow examination of the damage in the intermediate pressure turbine area. The aircraft examination is continuing, a number of wing and body fairing panels have been removed from the aircraft to facilitate the examination of the underlying structures and systems. This work is going to continue at least for the remainder of the week. The search in Batam for debris has recovered several turbine blades and blade attachments but failed to retrieve the missing parts of the turbine disk."

"On Nov 22nd the ATSB reported, that the low pressure and intermediate pressure turbine modules including the shafts have been removed from the engine. Together with the recovered parts of the intermediate pressure turbine those parts of interest are being shipped to Rolls Royce for further examination under the supervision of the British AAIB. The examination of the airframe is continuing with the focus now on hydraulic, mechanical and electric systems that have been affected by engine debris. The ATSB expects their on-site investigators will be able to return to Australia by Friday Nov 26th. No further update is to be expected until the release of the preliminary report on Dec 3rd."

"On Nov 22nd the EASA released an updated Emergency Airworthiness Directive 2010-242-E, which supersedes EAD 2010-236-E following progress in the accident investigation of flight QF-32.

The EASA wrote: "The results of this analysis show the need to amend the inspection procedure, retaining the inspection of the air buffer cavity and focusing on the oil service tubes within the HP/IP structure. For the reasons described above, this AD partially retains the requirements of AD 2010-0236-E, which is superseded, and requires implementation of the amended procedure and accomplishment of the associated inspections."

Rolls Royce released an updated inspection procedure in their "Non Modification Service Bulletin (NMSB) 72-AG590 Revision 2, Section 3, paragraphs 3.A or 3.B, as applicable to the engine configuration.", which is now to be repeated at the latest every 20 flight cycles.

The updated EAD is still considered to be interim action."

"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."

Jeopardy! last night featured a category about this plane which the contestants answered well but none of the questions concerned engines coming apart.

Qantas and RR have settled.  Incident aircraft to remain out of service until Feb 2012.
