Rolls-Royce admits it ‘fell short’ in Qantas explosion


Rolls-Royce yesterday admitted its safety and quality standards “fell short” after Australia’s transport safety watchdog found cracks in an oil feed pipe caused an engine to explode on a Qantas A380 in 2010.

The airline grounded its entire Airbus A380 fleet after one of the Sydney-bound double-decker superjumbos was forced to make a dramatic return to Singapore with smoke trailing from its Rolls-Royce Trent 900 engine and damage to its wing.

The mid-air blast in November 2010 sent debris raining down over Batam Island in Indonesia, before pilots guided the plane carrying 469 passengers back to Changi Airport. No one was injured.

The Australian Transport Safety Bureau (ATSB) yesterday released its third and final report into the accident, which found that oil feed pipes in the A380’s No. 2 engine did not conform to design specifications.

“The ATSB found that the engine failure was the result of a fatigue crack in an oil feed pipe,” the bureau said, calling the investigation one of the most complex it had ever undertaken.

“The crack allowed the release of oil that resulted in an internal oil fire. The oil fire led to one of the engine’s turbine discs separating from the drive shaft. The disc then over-accelerated and broke apart, bursting through the engine casing and releasing other high energy debris,” it said.

The ATSB also found that the oil pipe, together with a number of similar pipes in other engines, had been made with a thin wall section and did not comply with design specifications.

The company’s engineering and technology director Colin Smith said it was “a serious and rare event which we very much regret.”

“At Rolls-Royce we continually strive to meet the high standards of safety, quality and reliability that our customers and their passengers are entitled to expect. On this occasion we clearly fell short,” he added in a statement. “The robustness of the Airbus A380 and the professionalism of the Qantas crew members assured that the aircraft and all its passengers landed safely.”

Qantas, which reached a settlement worth US$104 million with Rolls-Royce in June 2011 over the incident, welcomed the findings.
