HOW MANY TYPES OF A350 ARE THERE?
The Airbus A350 is a long-range, twin-aisle airliner that can carry between 300 and 480 passengers. It is available in two sizes: the A350-900 and the larger A350-1000, both powered exclusively by Rolls-Royce engines.
WHAT ENGINE DOES THE A350 USE?
The A350-1000 and A350 Freighter use Trent XWB-97 engines, Rolls-Royce’s largest civil jet engine.
The most popular A350-900 uses its Trent XWB-84 engines.
ARE ALL A350 ENGINES AFFECTED?
Cathay Pacific said the incident occurred on one of its 18 A350-1000 aircraft. It has since identified 15 aircraft with engine components requiring replacement and three have already been repaired.
On Tuesday, Rolls-Royce said the replacement could be done while the engine remains on the wing. It also said it was committed to working closely with Cathay Pacific, Airbus and authorities conducting an investigation into the incident. The engine maker did not immediately respond to a request for comment on the reported fuel nozzle problem.
HOW MANY A350 AIRCRAFT COULD BE AFFECTED?
There are 88 A350-1000 aircraft in operation worldwide, according to Swiss aviation intelligence provider ch-aviation.
The top six operators are Qatar Airways with 24 aircraft, British Airways with 18, Cathay Pacific with 18, Virgin Atlantic with 12 and Etihad Airways and Japan Airlines with five each.
There are 520 A350-900s in operation worldwide, ch-aviation data showed.
It is unclear whether other airlines are inspecting their engines.
Broker Jefferies said in a note to clients on Monday that 234 XWB-97 engines had been delivered to customers through the end of June.
