Rolls-Royce Launches First of Two New Trent 1000 Durability Enhancement Packages

Rolls Royce has launched the first of two Durability Enhancement Packages that will more than double time-on-wing for Trent 1000 engines.  This will improve asset utilization, while reducing the maintenance burden, and providing greater fleet planning certainty.

On Thursday (June 12, 2025), Rolls-Royce announced the launch of the first of two Durability Enhancement Packages that will more than double the time Trent 1000 engines remain in service before needing scheduled maintenance.  By increasing ‘Time on Wing’, customers will benefit from improved asset utilization, a reduced maintenance burden, and greater fleet planning certainty.  The durability enhancement complements the Trent 1000 engine’s already excellent reliability, and the package has been installed in new engines since January 2025.  Now, the Durability Enhancement Package will be distributed to maintenance facilities globally, to be retrofitted to in-service engines.  Rolls-Royce estimates that the entire Trent 1000 fleet will be upgraded within two years. 

In Thursday’s announcement, Rolls-Royce’s CEO, Tufan Erginbilgic, said,

“The Trent 1000 is an important engine for us and today marks a new chapter in its story.  When upgraded, we’re confident that our customers and their passengers will benefit from increased durability, thanks to the proven enhancements that have already surpassed our expectations on the Trent 7000.  As part of our ongoing transformation, the investment we have made in new technologies will see the Trent 1000 deliver for Boeing, our customers and our investors.  It’s a win-win for everyone involved.”

Also commenting on the Durability Enhancement Package rollout, Rolls-Royce Civil Aerospace’s President, Rob Watson, added,

“Today is an important day for Rolls-Royce, our customers and our partnership with Boeing.  We know that the same enhancements have already tripled Time on Wing in some cases for the Trent 7000, so we are confident it will deliver for Trent 1000 customers.  To do so at pace, we began installing the enhancements into new engines prior to today’s certification to reduce the lead time as much as possible. They will now enter the fleet immediately.”

Since 2022, the upgraded components have already been enhancing durability on the Trent 7000 engine, in some cases more than tripling Time on Wing.  As part of the Trent fleet £1 billion durability enhancement programme, the new technologies will contribute to Rolls-Royce meeting their mid-term targets to increase Time on Wing across all modern Trent Family engines, including the Trent 1000, Trent 7000, Trent XWB-84, and Trent XWB-97.

The first phase durability enhancement includes a 40 percent increase in cooling to the new high pressure turbine blade, as well as updated to the combustion system, fuel spray nozzles, and engine electronic controller software.  Currently being tested at Rolls-Royce’s facility in Derby, UK, phase two of the Durability Enhancement Package is expected to bring an additional 30 percent improvement in Time on Wing across the Trent 1000 and 7000 fleets after rolling out in early 2026.  The second phase package features an advanced coating on combustor tiles, cooling and coating changes to high-pressure nozzle guide vanes, weight reduction and coating improvements to high-pressure turbine blades, and a redesigned combustor-to-turbine interface taken from the latest variant Trent XWB-84 EP.
