The Engine Problem That Won’t Go Away: Five Facts Behind the Airbus-Pratt & Whitney Standoff
The headlines read like a resolution: Airbus delivered 793 aircraft in 2025, surpassed its revised target, and recorded a record backlog of 8,754 aircraft. But buried in the fine print of Christian Scherer’s final press conference as Commercial Aircraft CEO was an admission that cuts through the celebratory numbers. Despite everything—despite a year of promises, daily negotiations, and billions in investment—Airbus still has no agreement with Pratt & Whitney on engine supply “for the foreseeable future.”
This isn’t just another supply chain hiccup. What’s unfolding between Toulouse and East Hartford represents one of the most consequential partnerships in commercial aviation, and it’s showing cracks that neither side seems eager to fully acknowledge. For airlines waiting on aircraft and passengers wondering why their new jets keep getting delayed, the reality is more complex—and more fascinating—than the press releases suggest.
The “Very, Very Late” Problem
Let’s start with the language Scherer chose. Not “slightly delayed” or “behind schedule”—but “very, very late.” Engines for the A320neo family, he told reporters on January 12, continued arriving well past their committed dates throughout 2025. And here’s the kicker: he expects that trend to continue into 2026, particularly with Pratt & Whitney.
The specific words matter here. Aviation executives tend toward understatement, preferring euphemisms like “supply chain challenges” or “industrial coordination.” When a departing CEO—someone with nothing left to lose politically—describes engines as arriving very, very late, the situation is likely worse than the sanitized public statements suggest.
What makes this particularly striking is the context. Just two months earlier, at the Dubai Air Show in November 2025, Pratt & Whitney’s commercial engines president Rick Deurloo told reporters the company had delivered enough engines for Airbus to meet its 2025 targets. The two narratives don’t quite align, and the gap between them tells us something important about how differently the two companies view “success.”
Sixty Gliders and a Shrinking Number
Mid-2025 saw something that would have been unthinkable a decade ago: approximately 60 completed Airbus aircraft sitting on tarmacs, structurally finished but unable to fly because they lacked engines. The aviation industry has a darkly humorous name for these—”gliders”—as if multi-million-dollar narrowbody jets might simply coast to their destinations.
By year’s end, Scherer reported the number had been “burnt down” to a “manageable” figure. Progress, certainly, but consider what that phrase reveals. The fact that having some engineless aircraft parked is now considered manageable shows how dramatically expectations have shifted. A decade ago, a single glider would have triggered crisis meetings. Now it’s just another variable in the production calculus.
The improvement came partly because CFM International, the GE-Safran joint venture that supplies the competing Leap-1A engine, stepped up deliveries. Airbus CEO Guillaume Faury noted in October that the glider count had halved to 32 by September’s end. But he also acknowledged that Pratt & Whitney was responsible for more of the outstanding engine gap than CFM—a detail that contextualizes the public pressure Scherer applied to the Connecticut-based manufacturer in his final days on the job.
A Rate 75 That May Only Exist on Paper
Airbus has staked its industrial future on reaching 75 A320-family aircraft per month by 2027—the highest production rate in commercial aviation history. To get there, the company has opened new final assembly lines in Mobile, Alabama, and Tianjin, China. Hamburg’s four assembly lines have been upgraded to handle the popular A321 in all its variants. Enormous capital has flowed into transforming former A380 facilities into A320 production centers.
But here’s what doesn’t get mentioned as often: rate 75 requires an extraordinary number of engines. At current engine-per-aircraft ratios (two per narrowbody), Airbus needs 150 new engines every month just for A320-family production. That’s before accounting for spare engines airlines need for their operating fleets, replacement engines for maintenance rotations, and the engines required for A220 production (where Pratt & Whitney is the sole supplier).
The math exposes a stark truth. Airbus can build all the assembly lines it wants, but if the engines don’t arrive, those facilities will produce more gliders, not more delivered aircraft. Scherer’s parting confidence—”We’ll achieve this rate. Of course it’s achievable.”—reads differently when you understand that achieving it depends entirely on companies over which Airbus has no operational control.
Safran’s CEO Olivier Andries hinted at the timeline reality in October: to his knowledge, Airbus hasn’t actually committed to full-year rate 75 production in 2027, only to reaching that rate capability at some point during the year. The distinction matters more than it might seem.
The GTF’s Unfinished Durability Story
To understand why Pratt & Whitney finds itself in this position, we need to rewind to 2023. That July, RTX disclosed that contaminated powdered metal had been used to manufacture certain engine parts during a multi-year production window from late 2015 through September 2021. What started as concern over 1,200 engines ballooned to encompass the entire GTF fleet of approximately 3,000 units.
The technical issue—metal impurities that could cause premature cracking in high-pressure turbine disks—isn’t inherently damning. Modern jet engines push materials to their physical limits, and occasionally something slips through. But the fallout has been extraordinary. Shop visit inspections that once took 60 days now stretch to 250-300 days. At peak disruption in early 2024, roughly one-third of all GTF-powered jets were sitting in storage—over 600 aircraft. RTX took a $5.4 billion charge and expects the issue to cost between $6-7 billion when fully resolved.
For Airbus, this creates a challenging dynamic. Every engine that goes to a shop for inspection is an engine that isn’t available for new aircraft production or as a spare for an airline. Pratt & Whitney is essentially running two production tracks simultaneously: building new engines and rebuilding its relationship with operators who’ve had aircraft parked for months.
The company has made progress—CFM’s success at rolling out durability improvements shows what’s possible—but the GTF’s problems feel like a tax on every discussion about future supply. Airlines remember. Lessors remember. And Airbus, which has staked its single-aisle dominance on the A320neo family, cannot afford for its customers to remember too much.
The CEO Transition Hidden in Plain Sight
Christian Scherer’s departure wasn’t exactly unexpected—Airbus announced Lars Wagner as his successor back in July 2025—but the timing adds texture to recent events. Scherer spent over 40 years at Airbus, including stints running ATR and leading sales at Airbus Defense and Space. He was instrumental in the A320neo program’s development and the company’s U.S. expansion.
Wagner, meanwhile, arrives from MTU Aero Engines, one of Pratt & Whitney’s key partners in the GTF program. MTU holds an 18% stake in the geared turbofan venture and manufactures critical components. Wagner’s engine industry background was explicitly cited as valuable for his new role—a none-too-subtle acknowledgment that propulsion will dominate the agenda.
During his first public appearance as CEO, Wagner reflected on his career path: he’d previously worked at Airbus in production and strategy before leaving for MTU in 2015. His comment that the engine expertise “is so helpful now, as we talk lots about engines in my new position” generated knowing laughs but also underscored a serious point. Airbus needed someone who could navigate engine politics from experience rather than theory.
The transition also shifts negotiating dynamics. Scherer, in his final weeks, applied public pressure on Pratt & Whitney that felt unusually direct for aerospace norms. Wagner, with his MTU background and presumably ongoing industry relationships, may take a different approach. Whether that works better or worse for Airbus remains to be seen.
What the December Panel Crisis Revealed
Just as 2025 seemed to be limping toward a manageable conclusion, a new problem emerged. Spanish supplier Sofitec Aero had produced fuselage skin panels with thickness deviations outside tolerance—panels that had been installed on potentially 628 aircraft, including 168 already in service.
The issue wasn’t an immediate flight safety concern; regulators stressed that from the start. But it forced Airbus to cut its delivery target from 820 to approximately 790 aircraft and scramble through inspections across production lines. More significantly, it illustrated just how fragile modern aerospace supply chains have become.
Sofitec is what’s called a Tier-2 supplier—a company that feeds into larger integrators rather than directly to Airbus. The affected panels weren’t individually serialized, meaning Airbus couldn’t simply trace specific parts to specific aircraft. Instead, they had to inspect entire batches, grinding delivery flow to a crawl during the crucial December push.
Coming on the heels of the Spirit AeroSystems titanium documentation scandal and Boeing’s ongoing quality investigations, the Sofitec incident suggests a sector-wide vulnerability. OEMs have excellent visibility into their direct suppliers but far less insight into what happens two or three tiers down. When something goes wrong there, it can take months to untangle.
For the Pratt & Whitney negotiation, the panel crisis offered an unexpected talking point. Scherer noted that engines weren’t actually the delivery constraint by year’s end—the fuselage issue was. But that observation cuts both ways. If Airbus hadn’t been dealing with months of engine delays earlier in the year, December’s compressed delivery schedule might have had more margin for absorbing the panel problem.
Looking Forward: The Uncomfortable Questions
The Airbus-Pratt & Whitney relationship will continue because it has to. Pratt powers roughly half of all A320neo family orders and remains the sole engine option for the A220. Neither party can walk away from that commercial reality. But the unresolved supply agreement raises questions that matter far beyond the boardroom.
For airlines, engine uncertainty translates directly into operational risk. Carriers like Wizz Air have already postponed dozens of deliveries and scaled back A321XLR commitments amid supply concerns. Others are hedging by ordering CFM-powered variants or maintaining older aircraft longer than planned. The trust deficit created by years of GTF issues and ongoing negotiation limbo has real consequences for fleet planning.
For Airbus, the rate 75 ambition now looks as much like a bet on engine supplier performance as a statement about internal manufacturing capability. All the investment in new assembly lines, all the automation upgrades, all the workforce expansion—it only pays off if engines arrive. There’s something almost poetic about the world’s largest aircraft manufacturer finding its destiny tied to a company headquartered 6,000 kilometers away in Connecticut.
And for Pratt & Whitney, the stakes couldn’t be higher. The GTF was supposed to be the engine that secured P&W’s relevance against CFM’s decades of dominance. Instead, it’s become a case study in how quickly technological promise can curdle into operational burden. The company has the engineering talent to fix its durability issues—the progress on shop visit times and the new hardware upgrades prove that. But rebuilding customer confidence takes longer than rebuilding turbine disks.
What Happens Next
Lars Wagner inherits a negotiation in motion, not a crisis resolved. The coming months will reveal whether Pratt & Whitney can commit to the engine volumes Airbus needs for rate 75, and whether those commitments will prove more durable than past promises. Watch for signals from RTX’s quarterly earnings calls, where executives tend to be slightly more forthcoming about manufacturing constraints than they are in public settings.
Watch, too, for how CFM positions itself. The GE-Safran venture has been quietly capitalizing on Pratt’s difficulties, and Safran CEO Andries has been careful to emphasize his company’s alignment with Airbus on 2026 and 2027 engine needs. If airlines continue shifting orders toward Leap-powered aircraft, Pratt’s negotiating leverage diminishes—creating pressure to lock in deals before the market tips further.
Most of all, watch the glider count. If it creeps back toward 60, or higher, expect the public messaging to sharpen again. Aerospace companies can hide a lot behind confidentiality provisions and negotiating room claims. But fully assembled jets sitting engineless on tarmacs? Those are hard to explain away.
The engine that powers the world’s most popular narrowbody aircraft should be a triumph of industrial coordination. Instead, it’s become a reminder that even in an era of advanced manufacturing, the supply chain remains stubbornly human—prone to errors, delays, and the uncomfortable reality that no single company controls enough to guarantee success alone.
For now, we’re all just waiting to see if the engines arrive.
