Australian authorities recommend more inspections for the A380 Rolls-Royce Trent 900s

Australia's Transport Safety Bureau (ATSB) and Civil Aviation Safety Authority (CASA) have released their safety recommendations and the results of the preliminary investigation relating to the failure of a Rolls-Royce Trent 900 engine on a Qantas A380 last month. The report by the ATSB identifies an overspeed-related failure in the intermediate pressure turbine disc in the engine, and identifies a potential manufacturing defect with an oil tube connection to the high-pressure (HP)/intermediate-pressure (IP) bearing structure of the Trent 900 engine. Qantas has gained an injunction against Rolls-Royce in the Australian Federal Court and now pushes its claims for compensation, with the background threat of further litigation if agreement on terms is not possible.
