HOW MANY TYPES OF A350S ARE THERE?
The Airbus A350 is a twin-aisle long-haul aircraft that can carry between 300 and 480 passengers. It comes 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 the A350 freighter use Trent XWB-97 engines, Rolls-Royce’s largest civil jet engine.
The more 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 planes. It has since identified 15 aircraft with engine components that require replacement and three have already gone through repairs.
Rolls-Royce on Tuesday noted the replacement could take place while the engine remained on-wing. It also said it was committed to working closely with Cathay Pacific, Airbus and authorities conducting an investigation of the incident. The engine manufacturer did not immediately respond to a request for comment on the reported fuel nozzle problem.
HOW MANY A350 AIRCRAFT COULD BE IMPACTED?
There are 88 A350-1000 jets in operation worldwide, according to Swiss aviation intelligence provider ch-aviation.
The top six operators are Qatar Airways with 24 planes, 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 not clear 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 by the end of June.
