LONDON » Rolls-Royce Group PLC says the failure of a Qantas A380 engine last week was specific to the Trent 900 series of engines and confined to specific component of the turbine engine that started an oil fire.

In a trading update Friday, London-based Rolls-Royce says the incident will cause full year profit growth "to be slightly lower than previously guided."

Chief Executive John Rose says safety is the highest priority for the company and it regrets the disruption it has caused. Qantas and Singapore Airlines have grounded nine A380s between them, while checks are also being run on Trent 900s used by Singapore Airlines and Lufthansa.

Rose says Rolls-Royce is working with plane manufacturer Airbus to enable airlines to "progressively bring the whole fleet back into service."
