First GTF Advantage

By Howard Hardee • Editor September 24, 2026 U.S. enginemaker Pratt & Whitney has delivered the first GTF Advantage turbofan to an airline customer, marking what the company believes will be a turning point in the program’s history. United Airlines recently took delivery of an Airbus A321XLR powered by a pair of the upgraded geared turbofans (GTFs), which P&W says will deliver improved thrust and fuel efficiency compared to present-day engines. The Advantage engines feature a new hot section, with upgrades allowing for “up to twice the time on wing compared to today’s GTF engine,” P&W said. The company says the new units are “fully intermixable and interchangeable with today’s GTF engine model, simplifying operations for airlines like United that maintain combined fleets.” P&W has been grappling with a massively disruptive, years-long recall of GTF engines, which are one engine option for the A320neo family, and also power A220s and Embraer E190-E2 family jets, though issues with the PW1500G and PW1900G engines that power A220s and E2s, respectively, are nearly resolved. Issues with the larger PW1100G engines that power A320neos will take longer to work through. During the company’s earnings call in July, P&W said that year-over-year PW1100 aircraft-on-ground levels had declined by 25% year to date. As the enginemaker has accelerated engine removals and inspections to address a powdered metal manufacturing defect, hundreds of narrowbodies have been grounded globally on a rolling basis since July 2025. However, P&W has been expanding maintenance, repair and overhaul (MRO) capacity to address durability issues with critical GTF components. During a pre-Farnborough International Airshow briefing with reporters in July, Rick Deurloo, the president of P&W’s commercial engines unit, declined to put a hard date on when the company’s GTF headaches will be fully in the rearview mirror. “What I would say…is that we continue to make incredible progress,” he said. “Without giving you a time period, I think if you went to our customers, they’d tell you it feels sooner than they were anticipating. I’m not going to put a hard date on it. But, by the end of this year, we’re going to be in a really good position to finally, in 2027 or 2028, kind of get this behind us.” Earlier this year, P&W secured FAA and EASA certification for the GTF Advantage. A full production cutover is expected in 2028, meaning that, by then, P&W will be delivering all GTF Advantage units on new aircraft. The company also intends to roll out additional materials and improvements for GTF engines over the next several years. Re: “twice the time on wing compared to today’s GTF engine” What does that mean compared to the LEAP 1A? Yes. Whats that number compared to the brochure claim when airlines ordered the GTF. Apparently its “up to twice the time on wing,” they are comparing it to the actual, realized TOW of current-generation GTF engines . Thats a low standard to compare and it appears its just back to where the hot section should be, 10-15k hours operation The extra thrust as a PIP doesn’t seem much for the weight jump for the A321 to the XLR version Is this too a smokescreen for the below performance XLR range on specific routes some airlines have found, and this returns to the book numbers What is the increased weight/mass? And why does it take a full year plus to now ‘transition’ production if they are delivering some already? I’ve yet to see evidence of XLR routes being operated that an LR could not perform. It takes a while to ramp production. Sometimes there are multiple suppliers that need to come onboard…and this is not one part that is changing…it is half an engine. It Will be most valuable on the A321XLR. We will see UAL’s experience as the fleet grows and accumulate hrs a cyc. Is there any info about how the time on wings of the pre-Advantage version compares to the Leap 1A? I was under the impression that is was way worse and hence a doubling the time on wings of the Advantage is an nice improvement but still way too little. We think the time on wing of Advantage should be in the same ballpark of the Leap 1A if it performs as advertised, but there won’t be a clear answer until the Advantage engines are widely deployed in a variety of environments. I was once informed t hat there are only 8000 hours in a year. So all they could tell me was the compressor has run a year and was good. Sadly, if you run it faster, it is not relevant to what normal is (and for an engine the cycle time of takeoff/climb and cruise and decent). So, what they say is what they either think or hope, it could be worse, it could be what they said or it could be better. Time will tell, and only time will tell. Single aisle aircraft utilization is nominally around 3000 hours per year for most aircraft. Widebodies will fly north of 4000 hours. It is the gate time from multiple legs that really makes a difference. I gather they got so many new parts and engines a year. And they won’t have a complete change until 2028. So who gets what engines? This sounds very much like the issues RR has had struggled with on their T1000 engine. Any insights on the PW GTF you would like to share as you’ve had on the Trent T1000 these past few year? I mentioned this in an earlier comment. There are enormous supply chain changes. It is a cruise ship of supply. It needs a while to get to scale. The Advantage is borderline a new engine. Hot section plus is retrofit package off the base engine that gets most of the benefit. According to P&W: “The Advantage is designed to double on-wing life compared with the most updated pre-Advantage-standard PW1100Gs. The updated baseline PW1100G includes a series of durability improvements rolled out in recent years, in part to address challenges in harsher environments.” Initial LEAP engine has its own issues. ‘As Oman-based SalamAir looks to begin normalizing operations following the ceasefire in Iran, the LCC is struggling with aircraft availability as one-third of its Airbus A320neo-family fleet is grounded because of issues with their CFM International Leap-1A engines.’ https://aviationweek.com/air-transport/aircraft-propulsion/salamair-ceo-bemoans-durability-leap-1a-engines Not so. The update of the hot section doesn’t double the original specified Tow, just the airlines actual in service time which in standard operating conditions, un-upgraded original engines often had to be pulled from service at roughly 7,000 flight hours. Lower in severe conditions, sand, pollution dust The original “”projected”” service life would be around 15-20k hours, maybe 4-6 yrs Thats hasn’t doubled as that claim is ludicrous its just back where they started PW double speak in its tailored wording, which any understanding of engine life wouldn’t believe Does the LEAP engine meet CFM’s ‘original projected’ service life?? There are many complaints about unscheduled engine removal after only 20% of the original projected service life. Leap engines have also suffered a separate issue involving excessive coke accumulation on fuel nozzles due to heat-induced fuel evaporation after engines have been shut down.
