The airline, one of the world’s largest users of the long-haul jet, said it identified an engine component failure on flight CX383 from Hong Kong to Zurich on Monday. The plane later returned to Hong Kong.
“This component was the first of its type to suffer such failure on any A350 aircraft worldwide,” Cathay said in a statement sent to CNN. A thorough inspection of its 48-plane fleet revealed “a number of the same engine components that need to be replaced,” it added.
It did not detail the nature of the engine issue. Spare parts have been secured and repair work was underway, Cathay said. As a result, the carrier has cancelled 24 flights operating over two days, until Tuesday, pending the inspection and repair work.
According to Reuters citing an unnamed source, the incident involved a problem with a fuel nozzle, a component that directs fuel inside the engine. CNN has reached out to Cathay for additional comment.
The issue affecting the A350 has emerged after rival Boeing suffered a number of serious and high-profile problems. The American plane maker has spent months embroiled in a safety crisis since the mid-air blowout of one of its door plugs on a 737 Max flight operated by Alaska Airlines earlier this year.

Cathay said it had contacted the aircraft manufacturer about the engine problem, as well as the engine maker, Rolls-Royce, and regulators.
According to Airbus, the A350 family uses two Trent XWB turbofan engine models from Rolls-Royce.
The British aerospace company confirmed in a statement that flight CX383 was powered by a Trent XWB-97 engine, adding it was “committed to working closely with the airline, aircraft manufacturer and the relevant authorities to support their investigation into this incident.”
Its London-traded shares closed more than six per cent lower on Monday.
