Rolls-Royce Promises Triple Time-on-Wing for Troubled Trent 1000 with New Durability Package
DERBY, United Kingdom — Rolls-Royce is rolling out a second phase of durability enhancements for its Trent 1000 engine that the British manufacturer says will deliver up to triple the time-on-wing for Boeing 787 operators, marking a critical effort to restore confidence in a powerplant that has plagued airlines for nearly a decade.
The engine maker secured certification for the latest high-pressure turbine upgrades in late 2025, following regulatory approval from both European and American aviation authorities. Rachel Walker, the newly appointed Trent 1000 program manager, said the second phase of improvements should boost time-on-wing by an additional 30 percent on top of gains already achieved through an initial enhancement package approved last June.
The phase-two upgrades involve reducing the weight of the high-pressure turbine blade shroud to cut centrifugal stress and extend component lifespan. Rolls-Royce engineers have also applied new advanced coatings to the blades and nozzle guide vanes. Production blades incorporating these changes are nearly complete and will be installed in the first factory-fresh engines during the first quarter of this year.
“We believe these durability enhancements absolutely put us in a competitive position,” Walker said. “We are actively engaged with operators on any opportunity.”
The initial enhancement package, branded as the Trent 1000 XE, entered commercial service in November when Lufthansa took delivery of a 787-9 equipped with the upgraded powerplant. That first phase featured high-pressure turbine blades with 40 percent improved cooling flow, along with updates to the combustion system, fuel spray nozzles, and engine electronic controller software.
More than 50 in-service Trent 1000 engines have already received the improved components, and Rolls-Royce has committed to completing the fleet-wide rollout by the end of 2027. To meet that aggressive timeline, the company has expanded maintenance capacity at facilities in the United Kingdom, Germany, and Singapore, adding capacity for another 100 shop visits annually.
A Troubled History
The durability improvements represent the latest chapter in a saga that has cost Rolls-Royce billions of pounds and damaged relationships with major carriers worldwide. Problems first emerged in early 2016 when corrosion-related fatigue cracking was discovered on intermediate-pressure turbine blades in engines operated by All Nippon Airways, the Trent 1000’s launch customer.
By 2017, Rolls-Royce acknowledged that durability issues affected up to 500 engines across the global fleet. At its peak, the crisis grounded 44 aircraft while operators waited for replacement parts and maintenance slots. The fallout prompted both the Federal Aviation Administration and the European Union Aviation Safety Agency to reduce the Boeing 787’s extended-range twin-engine operations approval from 330 minutes to 140 minutes for affected powerplants.
Virgin Atlantic, which operates 17 Trent 1000-powered 787-9s, has been forced to delay new route launches and adjust schedules due to engine availability constraints. British Airways similarly cut services to destinations including Abu Dhabi and Dallas/Fort Worth as it struggled with engine and parts delivery delays.
The troubles gave rival GE Aerospace a substantial opening. The American manufacturer’s GEnx engine now powers roughly two-thirds of all Boeing 787s in operation, having dominated recent Dreamliner orders. Between 2017 and late 2024, airlines declared 640 new 787 orders for GEnx engines compared to just 96 for the Trent 1000.
Several Trent 1000 operators have switched allegiance entirely. LATAM Airlines took delivery of its first GEnx-powered 787-9 in late December, breaking with its previous all-Rolls-Royce fleet. ANA, the original Trent 1000 launch customer, committed to GEnx engines for its latest 787 orders. Lufthansa itself reportedly explored switching future deliveries to GE power, though it continues receiving Trent 1000-equipped aircraft for now.
Path to Recovery
Rolls-Royce is investing one billion pounds across its entire in-production Trent engine portfolio to address durability concerns. The company points to positive real-world results from the Trent 7000, a sister engine powering the Airbus A330neo that has already received similar upgrades.
Walker said operators have responded positively to the pace of the improvement program. Customer feedback indicates satisfaction with both the rollout speed and early engine performance, though she acknowledged it remains too early to assess long-term results.
“We know from our experience on the Trent 7000 we can see up to triple time-on-wing already from phase one,” Walker noted. “Certainly, the feedback we’ve been having from customers so far is that they are very positive.”
The company has also included its TotalCare support package as standard equipment on the XE variant, providing operators with predictable maintenance costs alongside the technical improvements.
El Al was the last carrier to select the Trent 1000 for new aircraft, placing an order in 2024. Rolls-Royce had 58 engines remaining to deliver as of year-end, leaving limited near-term opportunities to prove the XE’s capabilities to prospective customers.
Whether the improvements can arrest the Trent 1000’s market share decline remains uncertain. GE Aerospace continues winning major contracts, including a recent deal to power 30 new Delta Air Lines 787-10s with options for 30 more. The American carrier’s selection extends a supplier relationship stretching back to 1956.
For now, Rolls-Royce is focused on delivering promised reliability improvements to existing customers while positioning itself for future competitions. The company maintains there remains a substantial market to pursue in widebody propulsion despite recent setbacks.
