The ATSB has issued a safety recommendation about potential engine problems in some Airbus A380 aircraft.

The safety recommendation 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 installed in some A380 aircraft.

The problem relates to the potential for 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.

In response to the recommendation Rolls Royce, affected airlines and safety regulators are taking action to ensure the continued safe operation of A380 aircraft. The action involves the close inspection of affected engines and the removal from service of any engine which displays the suspected counter-boring problem.

The ATSB will hold a media briefing tomorrow (Friday 3 December 2010) at 10.30am to accompany the release of its preliminary factual investigation report into the QF32 occurrence. ATSB Chief Commissioner Mr Martin Dolan will present the known facts gathered from the investigation and highlight the key safety issues that have resulted from the investigation to date.

The full safety recommendation is available via the ATSB website at www.atsb.gov.au.
