香港航空事故调查局表示，本月早些时候导致 Cathay Pacific 整个 A350 空客机队因发动机问题而全部停飞进行检查的情况，可能会造成“严重损坏”。9 月初期，Cathay Pacific 因该问题取消了数十班航班。此前，航空公司在受影响的飞机上发现了一个引擎组件故障，但具体原因暂未公布。
在对其检验过程中，AAIA 发现燃油管存在明显的裂痕，并检测到黑色烟灰“表明有火灾迹象”。如果未能及时发现和处理，这种情况可能会发展成更严重的发动机火灾，导致飞机受损。初步报告还提到，在飞机两个反推力装置下发现了烧灼痕迹。
AAIA 建议欧洲航空安全局要求罗尔斯·罗伊斯（Rolls-Royce）开发有关此问题的持续适航信息。此次事件后，Cathay Pacific 对其 48 架 A350 飞机进行了彻底检查，并更换了其中 15 架飞机的部分组件。关于此事，CNN 已向 Cathay 和 Rolls-Royce 发送评论请求。
原文摘要：
Hong Kong aviation investigators say an engine problem that caused Cathay Pacific to ground its entire fleet of Airbus A350 jets for inspection earlier this month could have escalated into “extensive damage.” Cathay canceled dozens of flights in early September, citing the need to inspect its A350 planes after the engine issue forced a Zurich-bound flight to return to Hong Kong shortly after takeoff on September 2. The airline had previously identified an engine component failure on the affected aircraft, though it stopped short of revealing what the problem was. On Thursday, Hong Kong’s Air Accident Investigation Authority (AAIA) said it had found “a discernible hole” in the fuel hose, along with black soot “indicating signs of a fire,” during its own inspection. The AAIA said it was possible for fuel to leak through the ruptured hose, triggering a fire that could spread to surrounding parts of the engine. “If not promptly detected and addressed, this situation, along with further failures, could escalate into a more serious engine fire, potentially causing extensive damage to the aircraft,” it said. Burn marks were additionally found under the aircraft’s two reverse thrusts, which redirect exhaust to create a braking effect in order to slow a plane after landing, according to a preliminary report issued by the body. The AAIA recommended the European Union Aviation Safety Agency to require Rolls-Royce, the engine maker behind the popular A350 long-haul jets, to “develop continuing airworthiness information” on the problem. Following the incident, Cathay conducted a thorough inspection of its 48-strong A350 fleet and replaced components on 15 of the planes. The A350 family, which has two models, uses two different Trent XWB turbofan engines from Rolls-Royce. CNN has reached out to Cathay and Rolls-Royce for comment.
