Oil pump concerns spur order to de-pair Trent engines on older A330s and 777s

European and US regulators have issued an urgent directive addressing potential dual in-flight shutdown risks related to oil pumps on Rolls-Royce Trent-powered aircraft. Operators of Boeing 777s and older Airbus A330 variants are specifically impacted by this new requirement. The European Union Aviation Safety Agency (EASA) identified the concern, prompting the immediate action. This emergency directive mandates that certain engines be de-paired to mitigate the possibility of a simultaneous failure. Airlines are now obligated to implement these changes across their fleets to ensure passenger safety and operational reliability.
