The first aircraft powered by the Pratt & Whitney (P&W) GTF Advantage engine, an Airbus A321XLR, has been delivered to United Airlines (UA), with the engine maker claiming the upgraded powerplant will deliver up to twice the time on wing of the current GTF,
The new power plants performance has direct implications for MRO shop visit intervals across A320neo family fleets.
P&W, a subsidiary business of RTX, said the GTF Advantage also provides between 4% and 8% more take-off thrust than the current GTF, enabling longer range capability.
The engine is fully compatible with the current GTF model, allowing operators with combined fleets to run both variants without separate spares pools or maintenance arrangements.
P&W said it will transition its entire PW1100G-JM production line to the GTF Advantage specification by 2028.
For operators of existing engines, P&W will offer the GTF Hot Section Plus (HS+) upgrade for the PW1100G-JM.
The manufacturer said HS+ will allow customers to realise up to 90% to 95% of the GTF Advantage engine's durability benefits and will be available for incorporation during maintenance visits early next year.
P&W has not disclosed pricing for the HS+ upgrade or the expected impact on shop visit duration.
The durability improvements are relevant to low-cost and regional operators of GTF-powered A320neo family aircraft, many of which have faced aircraft groundings and constrained MRO capacity following P&W's powder metal inspection programme.
"GTF-powered aircraft are helping us reduce fuel burn and improve reliability as we add new destinations around the world for our customers," said senior vice-president and chief air operations officer at United Airlines Ankit Gupta.
Rick Deurloo, president of commercial engines at P&W, said the GTF Advantage was "particularly well-suited to the long-range A321XLR."
Neither company disclosed how many GTF Advantage-powered aircraft United has on order, the delivery schedule for further aircraft, or quantified fuel burn savings for the new engine variant relative to the current GTF.
The announcement did not specify when the HS+ upgrade will be available to operators outside the Americas, or whether MRO providers within the GTF network will be certified to incorporate it from launch.
