The recent engine problems experienced by Cathay Pacific's Boeing 747 fleet appear to be confined to the airline.
Other major carriers using the same Rolls-Royce engines said their performance had been excellent and problems had been 'very rare'.
Their remarks follow comments by Cathay that it had experienced 'several' recent shutdowns on 747s involving Rolls-Royce RB211 engines.
British Airways, Qantas Airways and South African Airways said they had experienced very few problems with the engines' performance.
They, Cathay and Air New Zealand are the only carriers internationally that use Boeing 747 aircraft powered by the Rolls-Royce RB211 engine involved in the recent incidents.
David Hedges, British Airways spokesman in London, said the performance of the engine had been excellent.
'We've had to perform far fewer stringent controls on our RB211s to ensure safe and reliable operation than on other products we operate,' he said.
