Airbus is pursuing damages from RTX unit Pratt & Whitney after chronic GTF engine failures left hundreds of completed new jets without engines, pushed deliveries 20% below target, and wiped 20% off the planemaker’s stock.
Airbus SE launched a damages claim against Pratt & Whitney, a unit of RTX Corp., over chronic Geared Turbofan engine delivery failures that have stranded hundreds of completed narrowbody jets without powerplants and driven the European planemaker’s stock down 20% this year.
The legal escalation, confirmed in March 2026, transforms what began as a supplier dispute into a formal cross-border commercial claim between the world’s largest jetmaker and one of America’s most strategically critical aerospace companies. Airbus CEO Guillaume Faury set the terms in February 2026, declaring the planemaker was prepared to “enforce contractual rights” — the first public signal that the relationship between the two companies had deteriorated beyond private remedy.
The dispute centers on Pratt & Whitney’s PW1000G Geared Turbofan family, which serves as the sole engine option for Airbus’s A220 series and powers roughly 40% of the A320neo fleet. A manufacturing defect in the engines’ powder metal components — a contamination condition in nickel-based superalloy powder used to produce high-pressure turbine and compressor disks — triggered a recall of approximately 1,200 engines after its disclosure by RTX in mid-2023. Shop visits that were initially estimated at 60 days have stretched past 300, draining the global pool of spare turbofans.
The bottleneck has produced a growing backlog of so-called “glider” aircraft: completed Airbus airframes that sit finished on the tarmac but cannot be delivered because no engines are available to install. Airbus contends that Pratt & Whitney diverted parts and finished engine units to its maintenance, repair, and overhaul operations to service in-service fleets rather than fulfilling commitments for new aircraft. That allocation decision, the planemaker argues, violated contractual obligations and triggered hundreds of millions of dollars in delay penalties paid to airline customers.
The dispute lays bare a three-way conflict over who gets priority access to limited engine supply. Airbus argues that new aircraft production is the foundation of long-term industry growth. Airlines — including Lufthansa, whose chief executive has publicly argued that keeping existing fleets airborne must come first — apply pressure from the other direction. Pratt & Whitney, for its part, faces higher margins and greater litigation exposure in the aftermarket than in new-build deliveries, giving it an economic incentive to prioritize fleet support over factory output.
RTX has not disputed the scale of the shortfalls. The company absorbed a $1 billion cash outflow in GTF-related compensation payments in 2025 and has guided 2026 free cash flow between $8.25 billion and $8.75 billion — a figure analysts note assumes no further deterioration in the engine remediation program.
The numbers at Airbus tell the same story. The planemaker delivered 54 aircraft in the first two months of 2026 — 19 in January and 35 in February — a rate roughly 20% below the 65 jets it shipped in the same period of 2025. Reaching its full-year target of 870 deliveries now requires a steep late-year acceleration that many industry analysts view with caution.
Both major Airbus narrowbody programs face exposure, but not equally. The A320neo family benefits from a partial hedge: CFM International’s LEAP-1A turbofan powers the remaining 60% of the fleet and has recovered from its own delivery challenges in 2025. The A220 family has no such alternative. Entirely dependent on the Pratt & Whitney PW1500G, the program delivered roughly four aircraft per month through early 2026 — far short of the 13-per-month target Airbus has set for 2028.
Rate 75 — Airbus’s ambition to produce 75 A320neo-family jets per month — is now delayed to the end of 2027. The company has adjusted its near-term production range to 70 to 75 aircraft per month to reflect the prevailing supply uncertainty. The A320neo accounts for more than 75% of Airbus’s total deliveries, making the engine supply gap the single most consequential variable in its 2026 financial outlook.
Airbus carries a backlog of 8,754 aircraft — approximately a decade of production — but that order book generates no revenue until jets are engined and delivered. Shareholders have taken note: the company’s stock has fallen 20% year-to-date, a decline management will face directly at its annual general meeting on April 14, 2026.
The crisis extends beyond commercial aviation. Every one of the 123 F135 engines — the powerplant for the Lockheed Martin F-35 Lightning II, manufactured by Pratt & Whitney — delivered to the Pentagon in 2024 arrived behind schedule, with an average delay of 238 days. Contracts for F135 production Lots 18 and 19 are expected to be finalized in spring 2026.
To address capacity constraints, RTX is investing $200 million to expand its engine components facility in Columbus, Georgia, adding a seventh isothermal forging press projected to increase output of critical engine disks by 30%. The expansion is not expected to come online until 2028.
Pratt & Whitney has advanced a remediation path for the existing GTF fleet. The company received Federal Aviation Administration certification for its GTF Advantage engine variant in 2025 and plans to roll out interim upgrades — involving 35 parts — to current operators through 2026. Pratt & Whitney projects those upgrades will improve engine durability by 90 to 95%.

Key Takeaways
- Airbus launched a damages claim against Pratt & Whitney in March 2026 over GTF engine delivery failures that have created a “glider” backlog and pushed early 2026 deliveries 20% below last year’s pace.
- The A220 relies exclusively on the PW1500G; Pratt & Whitney also powers roughly 40% of the A320neo fleet, leaving both programs acutely exposed to GTF shortfalls.
- Airbus’s 75-jets-per-month production target is delayed to end of 2027; the company’s stock is down 20% year-to-date ahead of its April 14 AGM.
- RTX paid $1 billion in GTF compensation in 2025; 2026 free cash flow guidance of $8.25–$8.75 billion assumes no further disruption.
- Pratt & Whitney’s delays also hit the Pentagon in 2024: all 123 F135 deliveries for the F-35 arrived late, averaging 238 days behind schedule.
