A350-900 with Trent XWB-84 Enhanced Performance engine receives EASA certification

Toulouse, France, 11 April 2025 – The European Union Aviation Safety Agency (EASA) has certified the A350-900 with Rolls-Royce Trent XWB-84 Enhanced Performance (EP) engine. The Enhanced Performance capability is set to deliver one percent lower fuel consumption, which will provide airlines with a reduction in overall operating costs as well as emissions.

The Trent XWB-84 EP is an evolution from the current A350-900’s engine, incorporating design improvements, including upgraded fan, compressor and turbine aerodynamics and enhanced turbine blade cooling. This certification milestone, which is the culmination of an extensive ground and flight-test programme, demonstrates the continuous development and improvement of the A350-900 and its Trent XWB engines since the family’s entry into service 10 years ago.

The confirmation of the EASA approval will be followed in the very near future with the FAA’s corresponding certification – paving the way for operation of this new engine variant by airlines worldwide.

"With EASA's certification of the Trent XWB-84 EP to power the A350-900, we strengthen the aircraft's position as the long-range leader. Together with our partner Rolls-Royce, this latest evolution underscores our joint commitment to continuous improvement and innovation. The Trent XWB-84 is already among the most efficient widebody engines on the market and this enhanced version will deliver even greater performance and efficiency for our airline customers,” said Julien Puyou, Airbus’ Head of Widebody Programme. 

The A350 is the world’s most modern and efficient widebody aircraft and the long range leader in the 300-410 seater category. It includes state-of-the-art technologies, aerodynamics, lightweight materials and latest generation engines that together deliver a 25% advantage in fuel burn, operating costs and CO₂ emissions. The A350’s unique Airspace cabin offers passengers and crews the latest modern in-flight products for a comfortable flying experience.

As with all Airbus aircraft, the A350 aircraft is already able to operate with up to 50% Sustainable Aviation Fuel (SAF). Airbus is targeting to have its aircraft up to 100% SAF capable by 2030.

At the end of March 2025, the A350 Family had won more than 1,300 firm orders from 60 customers worldwide.
