QQ infos d'Australie !
Un point intéressant sur les tuyaux d'huile dont les usinages sont excentrés !
Bon en en trouve d'autres ! A remplacer, bien sûr !
Noter aussi qu'un A380 à livrer à Qantas est affecté
Explication embarrassante ... ben, c'est comme chez Luft,ou ils en ont trouvé un aussi les A-B-C sont mélangés en production !
Drôle de désordre en plus un vrai Chop-Suey de moteurs ! Chez RR ou Airbus ??
Les Softwares se mettent en place c'est bien !
Bon hors canalisations, l'ATSB est curieusement silencieux !
Pour les arbres et les accouplements ... ou autres roulements, circulez il n'y a rien à voir !
------------ L'Article de l'Australien, des fois que RR le fasse caviarder ------http://www.theaustralian.com.au/business/aviation/global-air-safety-checks-reveal-more-faulty-engines/story-e6frg95x-1225967889418
A GLOBAL check of 45 Airbus A380 engines built by Rolls-Royce has given Qantas's existing A380s a clean bill of health.
But the check has found a problem with one of the flying kangaroo's undelivered superjumbos.
The Australian Transport Safety Bureau revealed yesterday that problems had been found with three Trent 900 engines after inspections it recommended last week were adopted by Rolls and conducted at Qantas, Lufthansa and Singapore Airlines.
The finding appears to confirm that there was a batch of faulty oil pipes that were unevenly bored during manufacturing.
Investigators believe that an oil leak that led to a damaging fire inside the engine of an Qantas A380 after take-off from Singapore last month most likely stemmed from fatigue cracking on the thin side of the tube.
The fire caused superheating in the turbine disc area, which led to the disintegration of the intermediate pressure turbine disc and substantial damage to the aircraft.
Qantas chief executive Alan Joyce confirmed last night that one of the problem engines was on an undelivered Qantas plane and that delivery of the plane, due before Christmas, was on hold while Rolls-Royce and Airbus replaced the engine.
Mr Joyce said he did not believe the discovery would affect Qantas's plans to reintroduce the four-engine A380s and it would still get four aircraft operational by Christmas and it would probably have a fifth one by the end of the year.
Mr Joyce said the findings of other engines with the problem also showed there was a batch of oil pipes with the boring defect."There's been a manufacturing problem and it's not a once-off with one engine, it's gone through to a number of different engines," he said. "I think that it's good that we're homing in on it because it means we can replace the engines before they're an issue."
Two sets of modifications mean there are three versions of Trent 900s on A380s with only those with the latest "C" modification believed to be defect-free.
Mr Joyce did not know last night what version of the engine had been found on the undelivered plane but said it was not a "C". The situation has been confused because later planes do not necessarily have the latest engines.
inspections covered 29 engines installed on aircraft as well as eight not on aircraft, four on test planes and four due to be delivered.
It is understood a Lufthansa engine, believed to be an earlier "A" version, was found with the problem and Singapore last night confirmed it had a "precautionary" engine change.
ATSB chief commissioner Martin Dolan said all the engines listed by Rolls as needing to be checked had now been inspected.
Mr Dolan said an engine control software upgrade approved last week by the European Aviation Safety Agency had also been installed on all operating aircraft and provided another line of defence.
The software upgrade predicts problems with the intermediate pressure turbine and shuts the engine down before a turbine disc failure occurs.
Singapore Airlines said yesterday it would reintroduce some A380 services to Sydney from Friday.
