Airbus Expresses Confidence in Trent XWB-97 Engine for A350F

Airbus Reaffirms Confidence in Trent XWB-97 Engine for A350F Amid Durability Concerns
Airbus has reiterated its strong confidence in the Rolls-Royce Trent XWB-97 engine, which will power its forthcoming A350F freighter, despite recent concerns regarding the engine’s durability in harsh operating environments. At the company’s 2025 Cargo Global Market Forecast, Crawford Hamilton, Head of Freighter Marketing at Airbus, described the Trent XWB-97 as an “excellent and highly efficient engine.” He emphasized that ongoing enhancements by Rolls-Royce are expected to ensure the engine fully meets all programme requirements by the time the A350F enters service.
Test flights for the A350F are slated to commence in 2026, with entry into service planned for the latter half of 2027. Airbus anticipates strong demand for the new freighter, particularly across Asia, where carriers such as Air China Cargo and Korean Air have expressed significant interest. The company is also targeting a 7% increase in deliveries this year, aiming to reach 820 jets. This outlook is supported by improved supplier performance and a positive market position, even as competitors like Embraer intensify their efforts to capture market share.
Engine Performance and Durability Challenges
The Trent XWB-97 engine, delivering up to 97,000 pounds of thrust, is the same variant used on the A350-1000, while the A350-900 is powered by the lower-thrust XWB-84. The higher thrust of the XWB-97 results in elevated operating temperatures, which can accelerate wear, particularly in hot and sandy regions such as the Middle East. This has drawn criticism from some operators, most notably Emirates. In 2023, Emirates President Tim Clark expressed concerns about the engine’s time on wing, stating it was approximately one quarter of the duration the airline deemed necessary between maintenance visits. Clark indicated that Emirates would consider ordering 35 to 50 A350-1000s if Rolls-Royce could improve both durability and maintenance costs.
Rolls-Royce has acknowledged these operational challenges but maintains that the engine is not defective. Ewen McDonald, Chief Customer Officer at Rolls-Royce, explained that while the engine performs well under “benign operations,” it faces challenges in sandy, hot conditions due to the high temperatures involved—a difficulty shared across the industry.
Recent Incidents and Regulatory Response
Further scrutiny of the Trent XWB-97 arose in September 2024, when an engine fire on a Cathay Pacific A350-1000 led to the temporary grounding of the airline’s fleet. The incident was traced to a damaged main fuel hose assembly, which posed risks of fuel leakage, in-flight shutdown, or fire. In response, aviation authorities including the European Union Aviation Safety Agency (EASA) and the U.S. Federal Aviation Administration (FAA) mandated inspections across affected fleets. Rolls-Royce has since implemented design modifications to the fuel hose assembly and collaborated with regulators to complete the necessary inspections.
The company now asserts that the Trent XWB-97 offers improved durability, even in demanding environments. Rolls-Royce notes that most engine wear occurs during take-off and climb phases, when operating temperatures are at their highest.
Despite these challenges, Airbus remains optimistic about the A350F’s market prospects, highlighting strong customer interest and ongoing enhancements to the Trent XWB-97 engine as key factors underpinning the programme’s anticipated success.
