Cathay Pacific Airbus fault could have caused major damage, says report

An engine ***** on a Cathay Pacific Airbus A350 earlier this month was the result of a fuel ***** and could have caused extensive damage to the plane, according to investigators.

Hong Kong’s flagship airline grounded planes after being forced to turn a flight around a couple of weeks ago because of an “engine component ********”.

The Trent XWB-97 engine was made by British engineering giant Rolls-Royce.

A preliminary report by Hong Kong’s Air Accident Investigation Authority (AAIA) said the incident was caused by a broken fuel hose – one of a number that had been damaged.

Rolls-Royce and Cathay Pacific have been contacted for comment.

The incident occurred shortly after the plane had taken off from Hong Kong en route to Zurich in early September. The pilots received a ***** warning in the cockpit, shut down the engine and deployed ***** extinguishers.

The aircraft, which was carrying 348 passengers and crew, landed safely back in Hong Kong.

But the incident raised concerns over the safety of the engines used across Cathay Pacific’s A350 fleet, particularly after checks revealed issues on another 15 aircraft.

The preliminary report found that the protective surround of a fuel hose had ruptured, leaving “a discernible ***** in the hose”. There were signs of a ***** in parts of the engine, including soot and ***** marks.

Further checks revealed another five fuel hoses in the same engine were also defective.

, this situation could have escalated “into a more serious engine *****, potentially causing extensive damage to the aircraft.”

To address the problem, the AAIA recommended that the ********* Union Aviation Safety Agency (EASA) require Rolls-Royce to develop new inspection requirements for the relevant engines.

EASA issued an “Emergency Airworthiness Directive” days after the incident. It required operators using the same type of engine to carry out inspections of fuel pipes, and remove any that were ‘potentially compromised’.

Cathay Pacific took delivery of its first Airbus A350 in 2016. The aircraft is rapidly becoming a mainstay of airlines’ long-haul fleets around the world. Its main selling point is its high efficiency and low running costs.

A key part of that efficiency is the engine. The Trent XWB was developed by Rolls-Royce specifically for the A350. The incident initially raised concerns that there could be a serious problem affecting the global A350 fleet. That would have been a major setback for the British manufacturer.

However, it rapidly became apparent that the issue did not affect the running parts within the engine itself, but rather fuel lines on the outside. That meant the problem could be rectified relatively quickly, without an expensive redesign.

It also only affected the XWB-97, a high power variant of the engine that was fitted to a relatively limited number of long-range aircraft.

This year, Rolls-Royce announced plans to invest heavily to improve its range of engines, including the Trent XWB-97.

In 2023, Tim Clark, the boss of gulf carrier Emirates, voiced concerns about the durability of the engine and the prices Rolls-Royce charged for maintenance.
