COLOGNE, September 5, 2024 — The European Union Aviation Safety Agency (EASA) has mandated inspections on the Airbus A350-1000 fleet, powered by Rolls-Royce Trent XWB-97 engines, as a precautionary measure following a serious incident concerning a Cathay Pacific flight from Hong Kong earlier this week.
In an Emergency Airworthiness Directive (AD) 2024-0174-E, EASA mandated a phased one-off inspection of flexible fuel hose connections inside the engines to check for damage. The inspections need to take place over the next 3-30 days, depending on the individual engine history. In total, 86 A350-1000 aircraft are in service worldwide.
“This action is a precautionary measure, based on the information received from the initial investigation of the recent Cathay Pacific serious incident and on the airline’s findings in its own subsequent inspections,” said EASA Executive Director Florian Guillermet. “We will continue to follow closely all information that will be made available through the ongoing safety investigation.”
On September 1, 2024, an A350-1000 aircraft, operated by Cathay Pacific on a flight from Hong Kong to Zurich, experienced an in-flight engine fire shortly after take-off. The fire was promptly detected and extinguished, and the aircraft returned safely to Hong Kong. The aircraft was powered by Trent XWB-97 engines.
This event was classified as serious incident, and an International Civil Aviation Organization (ICAO) Annex-13 investigation was opened by the Air Accident Investigation Authority (AAIA) of Hong Kong.
Following an inspection by Cathay Pacific of its A350 fleet, the airline reported similar problems on other aircraft.
EASA is State of Design airworthiness authority for the A350 aircraft and for the Trent XWB engines. The current measures are mandated for Trent XWB-97 engines. Trent XWB-84 engines, installed on the A350-900, are similar but differ in design and service history. On the basis of the available information, an extension of the measures to these engines is not warranted at this stage.
