Damage to Qantas A380 aircraft was more severe than thought

November 9, 2010

The Australian:

New suggestions have emerged that a spectacular engine failure near Singapore last week caused more damage to the plane involved than first thought. The No 2 engine’s violent disintegration ripped a hole through the Airbus A380’s left wing, destroying wiring that prevented the pilots from turning off the No 1 engine and causing a fuel leak. Suggestions have now emerged that there was also significant damage to hydraulic systems that prevented spoilers, panels on the wing that create drag to slow the plane down, from deploying.

The suggestions came as the Australian Transport Safety Bureau yesterday interviewed the flight crew of the stricken A380 and performed the first boroscope inspection of the Rolls-Royce Trent 900 engine. Investigators are continuing their search for the rest of a turbine disc that broke up in the incident and have set up a schedule for examining a recovered piece that has been sent to Britain for forensic tests.

Inspections of the grounded planes continued yesterday amid suggestions European regulators were poised to issue an airworthiness directive on the checks.

With this amount of damage to the wing it is a tribute to the pilots and to the Airbus A380 aircraft that the landing in Singapore was as smooth as it was and with no injuries at all.

Rolls Royce has said that the issues are specific to the Trent 900 and there are further indications that the issues may be specific to the engines as used by Qantas.

Rolls-Royce says that the uncontained engine failure on a Qantas Airbus A380 en route from Singapore to Sydney on November 4 “is specific to the Trent 900. We can be certain that the separate Trent 1000 event which occurred in August 2010 on a test bed in Derby is unconnected,” Rolls-Royce said in a statement yesterday. “This incident happened during a development program with an engine operating outside normal parameters. We understand the cause and a solution has been implemented.”

The engine maker added that it would provide a further update on the investigation with its interim management statement on November 12.
