“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.”
Cathay Pacific was operating a flight from Hong Kong to Zurich with an Airbus A350-1000 on 1st September when it 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 after dumping fuel. The aircraft was powered by Trent XWB-97 engines.
This event was classified as a serious incident, and an International Civil Aviation Organization (ICAO) Annex-13 investigation was opened by the Air Accident Investigation Authority (AAIA) of Hong Kong.
EASA is the 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.
