The Hong Kong Air Accident Investigation Authority (AAIA) found that a fire on a Cathay Pacific Airbus A350-1000 resulted from a damaged fuel hose on the engine. This incident led to a mid-air turnback and raised important safety concerns.

Details of the Cathay Pacific Incident

On September 2, the Cathay Pacific A350-1000, registered as B-LXI, was departing from Hong Kong International Airport (HKG) bound for Zurich Airport (ZRH). Shortly after takeoff, the flight crew received a fire warning for the number two engine. They followed the Airbus Electronic Centralized Aircraft Monitor (ECAM) procedures, which provided crucial engine information and suggested corrective actions.

Immediate Response and Emergency Status

The crew shut down the affected engine and discharged a fire extinguisher. The fire warning stopped within a minute. Initially, the crew declared a MAYDAY, a serious emergency signal, but later downgraded it to PAN PAN, indicating the situation was less critical.

Inspection Findings on the Engine

During the post-flight inspection, the AAIA discovered that the secondary fuel manifold hose connected to the engine’s fuel spray nozzle was ruptured. Black soot and burn marks on the engine’s core and thrust reverser cowls indicated a fire. Additionally, several other secondary fuel manifold hoses showed signs of wear or damage.

Safety Recommendations and Fleet Actions

The AAIA recommended that the European Union Aviation Safety Agency (EASA) inspect secondary fuel manifold hoses on Trent XWB-97 engines. EASA responded promptly, requiring inspections within specific time frames based on engine usage and previous shop visits.

Cathay Pacific took proactive measures by grounding its A350-1000 fleet for inspections. Although the airline did not face a global grounding order, it conducted thorough checks on its 18 A350-1000 aircraft. The airline adjusted its schedule to accommodate these inspections.

This incident highlights the need for rigorous maintenance checks to prevent fires and ensure passenger safety. Cathay Pacific remains committed to maintaining high safety standards before resuming regular flights.
