Australian Authorities Identify Trent 900 Defect

The Australian Transport Safety Bureau confirmed the potential existence of a manufacturing problem in Rolls-Royce Trent 900s fitted to some Airbus A380s in a safety recommendation it issued today. The recommendation identifies a potential defect in an oil tube connection to the high-pressure (HP)/intermediate-pressure (IP) bearing structure.

           
The ATSB suspects the cause to involve a misaligned oil pipe counter-boring, which could lead to fatigue cracking, oil leakage and potential engine failure from an oil fire within the HP/IP bearing buffer space. Both Rolls-Royce and the Australian authorities have recommended further inspection of the engines and removal from service of any engine that displays the suspected counter-boring problem.
