Question

Accepted Answer

Regulators Have Not Yet Mandated Global Checks on A350 Fuel Systems

Regulators have not yet mandated global checks on Airbus A350 fuel systems, although manufacturers Airbus and Rolls-Royce are preparing to brief airlines on the incident that prompted Cathay Pacific to review its fleet. While investigations are ongoing, the final decision on recommending worldwide checks rests with regulatory authorities.
Ongoing Investigation into Fuel Line Piercing

Investigations into the engine emergency that affected Cathay Pacific's A350 fleet are currently focusing on a pierced flexible pipe feeding a fuel injection nozzle in the Rolls-Royce XWB-97 engine. Hong Kong investigators are examining whether this hole was the initial cause of the fuel leak or a consequence of another, as yet unidentified, problem. This incident led Cathay Pacific to inspect 15 of its 48 A350 jets for fuel line repairs.
Airlines Conducting Precautionary Checks

In light of the Cathay Pacific review, some airlines, including Singapore Airlines and Japan Airlines, have proactively conducted precautionary checks on their entire A350 fleets. These measures are being taken while manufacturers and investigators work to understand the full scope and cause of the fuel line issue. To date, no other airline has reported similar damage to their fuel lines.
Manufacturers Leaning Against Worldwide Checks

Barring new evidence emerging from the ongoing investigation, manufacturers Airbus and Rolls-Royce have been inclined against recommending mandatory worldwide checks for the A350 fleet. However, the ultimate authority to mandate such checks lies with aviation safety agencies. The European Union Aviation Safety Agency (EASA) stated that it is still completing its assessment and has no further comment at this stage.
