The new AD supersedes EASA AD 2024-0174-E, which was issued in response to the serious incident with Cathay Pacific flight CX383 departing Hong Kong on September 2. The A350-1000 aircraft 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.
In-service and in-shop inspections since then have identified that a specific cleaning process available during engine refurbishment may lead to fuel manifold main fuel hose degradation. The new AD responds to this development.
EASA acknowledges the publication on September 19, 2024 of the preliminary report on the Annex-13 investigation from the Air Accident Investigation Authority (AAIA) of Hong Kong.
