Hong Kong’s flagship airline, Cathay Pacific, said on Tuesday that it had found that 15 of its Airbus A350 planes required repair after an engine component failed on a plane headed to Zurich. Cathay Pacific said it had inspected all 48 planes in its Airbus A350 fleet, adding that three of them had been fixed by Tuesday afternoon. It said it had canceled at least 34 round-trip flights since Monday because of the engine issue. All flights were expected to return to operation by Saturday. The carrier began the inspections after one of its A350 planes took off from Hong Kong International Airport on Monday before it experienced a problem, dumped fuel over the sea for half an hour and had to return to the airport. Rolls-Royce, the maker of the Trent XWB-97 engine that is used in the A350 planes, said Cathay Pacific had secured the spare parts needed to replace its components. Rolls-Royce stock fell 6.5% on Monday on the London Stock Exchange after it initially said it could not determine what caused the incident. The stock bounced back partly on Tuesday. “Rolls-Royce will now be in a better position to analyze and determine what the root causes of the failure are, and then it will tell Cathay and other operators what should be done next,” said Warren Chim Wing-nin, the deputy chairman of the aircraft division at the Hong Kong Institution of Engineers, a professional organization. Cathay Pacific did not provide details about the engine component that failed, but it said it was the “first of its type to suffer such a failure on any A350 aircraft worldwide.” Dozens of airlines around the world use the Airbus A350. In addition to Cathay Pacific, airlines with the biggest A350 fleets include Singapore Airlines, Qatar Airways, Air France, Delta Air Lines and Air China. Qatar Airways, which has 58 Airbus A350 aircraft, said that the operation of its fleet had not been affected but that it was “continuing to monitor any developments.” A spokeswoman for Singapore Airlines said that the airline was inspecting the Trent engines made by Rolls-Royce that power its Airbus A350 fleet and that there was currently no impact on any of its flights. Chinese news media reported that the Civil Aviation Administration of China was looking into whether it needed to inspect the A350 engines of its domestic carriers, including Air China, China Southern Airlines, China Eastern Airlines and Sichuan Airlines.<br/>

Qantas Group is replacing Jetstar on Melbourne–Honolulu with mainline Qantas services. The twice-weekly Jetstar 787-8 service will end on 30 April, to be supplanted in May by Qantas A330s, which will operate three times per week. Qantas says it will operate 40,000 seats on Melbourne–Honolulu per year, replacing 335 Jetstar seats per flight. Jetstar, which was the second airline to operate Dreamliners into Honolulu when it began services to the Hawaiian capital in 2015, will redeploy the 787s currently flying there to other routes. “We are thrilled to continue to enhance our network in America with the launch of a new route from Melbourne to Honolulu, bringing a new, tropical destination to our Melbourne customers,” Qantas International CEO Cam Wallace said. “Our new service ensures continued connectivity for Melburnians to Hawaii, while enabling Jetstar to redeploy its 787 aircraft to other destinations and long-haul routes.” Qantas and Jetstar’s Sydney–Honolulu services will remain unchanged; Sydney–Honolulu is also served by Hawaiian Airlines.<br/>
