Cathay Pacific has grounded its A350 fleet following an engine component failure. It is speculated to be related to the fuel nozzle. It has identified 15 aircraft with affected components - three of which have been repaired, the airline said on September 3, 2024. The remaining aircraft will continue to be out of service until repaired. ""We expect that all affected aircraft will resume operations by Saturday (7 September),"" Cathay said in a statement. Some 12 flights were cancelled for September 3, 2024. Around 21 flights were cancelled for the following day, however, it expects to cancel 10 additional regional return flights. It added that long-haul services should not be affected. Only one flight has been confirmed cancelled for Thursday, September 5, 2024. However, the airline expects to add cancellations on September 4, 2024. Following a flight travelling from Hong Kong to Switzerland on September 2, 2024, the airline identified an engine component failure in the A350 aircraft involved. ""We immediately brought this issue to the attention of the aircraft and engine manufacturers as well as our regulators,"" it read in a statement. ""As a precautionary measure, a fleet-wide inspection of our A350 aircraft was initiated immediately."" Around three flights were cancelled that day. The A350 only uses the Rolls-Royce Trent XWB series engines. Following initial reports, Rolls-Royce's shares tumbled sharply but have largely recovered as of September 3, 2024. It has yet to be seen whether other airlines' A350 fleet will undergo a similar inspection run. There are over 590 A350s in service. The main operators include Air China, Air France, British Airways, Cathay Pacific, Delta Airlines, Virgin Atlantic, Etihad, Iberia, Lufthansa, Qatar, and Singapore Airlines. Cathay Pacific's shares were down over 0.60% as of September 3, 2024, at 9:58 BST.
