The issue comes after the European Union Aviation Safety Agency (EASA) issued an emergency directive to airlines ordering mandated inspections on A350-1000s which are powered by XWB-97 engines made by Rolls-Royce.

The checks were prompted by an "in-flight engine fire" on one of Hong Kong-based Cathay Pacific's Zurich-bound flights.  Malaysia Airlines' fleet of A350-900 planes "recently underwent a precautionary inspection, during which a potential issue with high-pressure fuel hoses on one aircraft was identified," the carrier said in a statement. "This finding was swiftly resolved, and the aircraft has been fully cleared for service in accordance with stringent maintenance protocols," it added. On Friday, following the incident, EASA said extending its compulsory engine inspections to include the XWB-84 engines found on the Malaysia Airlines Airbus A350-900 is "not warranted at this stage".
