What Defined Engine Market in 2025?

For the aircraft engine market, 2025 was a particularly challenging year. Unexpected maintenance challenges and supply chain constraints drove record MRO activity, while airlines faced a substantial backlog and aging fleets, all placing significant strain on operations and resources.

Data from EngineStands.com reflects these pressures, with stands utilization rates rising sharply and leasing periods extending.

This article examines the key factors that shaped the engine market in 2025, the insights they provide for fleet and maintenance planning, and the outlook for the future of engine operations and MRO demand.

Engine Deliveries in 2025

CFM International continued to lead the commercial turbofan delivery charts in 2025 with its LEAP engines, powering the Boeing 737 MAX and Airbus A320neo. While final delivery data for 2025 has not yet been published, Safran reported 1,240 LEAP engines delivered through the first nine months of the year, representing a 21% increase compared with 2024. Based on Safran's third-quarter results, which indicated a 20% full-year increase, total LEAP deliveries for 2025 are estimated to fall between 1,618 and 1,688 units if the trend continued in Q4.

In early November 2025, Rick Deurloo, President of Commercial Engines at Pratt & Whitney, reported that the OEM had already supplied enough engines (PW1100G for A320neo, PW1500G for A220) to meet Airbus's 2025 revised aircraft delivery targets (790 aircraft), and was even delivering engines destined for 2026 production ahead of schedule. Also, Pratt & Whitney's Geared Turbofan family experienced significant commercial momentum, with approximately 1,100 engines ordered/committed in 2025 and an overall backlog exceeding 12,000 engines in June of 2025.

Precise delivery figures for widebody engines are not yet publicly available. However, industry data indicate that more than one-third of the widebody fleet, approximately 5,000 of 14,000 engines, already operates new-generation aircraft models including Trent XWB, Trent 1000, Trent 700, GEnx, and GE9X.

Engine Market Challenges in 2025 and MRO Impact

Despite the acceleration in engine deliveries in late 2025, current production remains insufficient to close the gap between airline demand and available aircraft and engines. The ongoing structural backlog of over 17,000 aircraft, equivalent to nearly 12 years of current production capacity, combined with ageing fleets and ongoing engine constraints that have left more than 5,000 aircraft waiting for engines in storage, continues to strain the industry. Airlines continue to face capacity limitations, higher operating costs, and delayed fleet modernization, highlighting that while deliveries are increasing, they are far from enough to meet the industry's near-term requirements, and the mismatch is expected to persist well into the early 2030s.

On top of these existing constraints, new-generation engines (PW1500, PW1100, LEAP-1A, LEAP-1B) required earlier and more complex repairs than anticipated, resulting in nearly 6,000 MRO events. Therefore, airlines operating Airbus A320neo, Boeing 737 MAX, Airbus A350, and Boeing 787 aircraft faced unexpected downtime. By late 2025, over 800 GTF engines were out of service globally, grounding almost 38% of the A320neo fleet, because contamination in turbine components caused cracks and prolonged inspection cycles. These reliability issues, combined with persistent shortages of hot-section parts, high-pressure turbine blades, and other critical components, further constrained production and delayed aircraft deliveries.

To mitigate these disruptions, airlines were forced to operate older aircraft longer, returning legacy engines such as CFM56, V2500 to MRO shops for more intensive, age-related maintenance, driving MRO demand up by almost US 23 billion. Moreover, turnaround times for engine overhauls increased sharply, rising 35% for legacy engines and more than 150% for new-generation engines compared with five years ago, and wait times for maintenance slots extended by two to six months, driving prolonged aircraft groundings and rising lease and spare part costs. Overall, engine maintenance costs in 2025 totaled USD 62.4 billion, with USD 29.6 billion for narrowbody engines, USD 27.4 billion for widebody engines, and USD 5.4 billion for regional engines.

Delayed deliveries and aging fleets also had direct financial impact, IATA estimated these factors cost airlines over additional USD 11 billion in 2025. This surge in MRO demand and aftermarket pressure highlighted the critical role of spare engine availability, inventory management, and long-term service agreements with OEMs, MRO, and ground supporting equipment providers.

2025 Engine Stand Demand and Operational Impacts

In 2025, EngineStands.com client base reflected shifting aftermarket dynamics, with demand drivers varying by customer segment:

Airlines drove strong demand for CFM56-7B, CFM56-5A/B, V2500, LEAP-1A, LEAP-1B, and PW1100 engines in 2025, highlighting operators' need to support aging fleets and managing durability challenges associated with new-generation engines.

Lessors were among the most active customer groups in 2025, with elevated stand utilization for both narrowbody (LEAP-1A, PW1100, V2500) and widebody engines (Trent700), highlighting their growing role in managing maintenance exposure and preserving engine value in a tight aftermarket.

Stand utilization linked to MRO activity was concentrated around widebody platforms Trent700 and PW4000-94, as well as select narrowbody models including CFM56-7B, CFM56-5A/B, and PW1500, reflecting backlog recovery efforts and increasingly complex maintenance events.

Traders contributed to episodic but meaningful demand in 2025, particularly for stands of most popular engine types such as CFM56-7B, PW1100, PW4000-94, and V2500. Trader-driven projects are typically associated with engine transitions, teardowns, or short-term holding periods.

Utilization and Project Duration Trends

This broad demand, combined with industry's increase in maintenance events and extended project timelines, translated directly into higher stand utilization at EngineStands.com across the engine families that dominated maintenance volumes in 2025.

For example, the utilization rate of stands for new-generation engine models more than doubled in 2025 compared with 2023, with the LEAP-1A model experiencing a remarkable 179% increase. Meanwhile, utilization of stands for legacy engine models rose by one third in 2025 compared with 2024, and CFM56-5A/B stands usage increase by 60%.

EngineStands also reports a significant year-on-year increase in rental durations in 2025, reflecting broader industry trends of longer turnaround times, limited availability of engine shop slots, and more intensive maintenance cycles overall.

Stands for narrowbody legacy engines, including CFM56-7B and CFM56-5A/B saw leasing periods extend by nearly 48% and 21%, respectively, while V2500 project timelines rose by 53%, driven largely by high numbers of aging aircraft still in service.

Exploitation of new generation narrowbody engine stands showed more dynamic trends. LEAP-1B engine stands leasing periods grew by 133%, whereas LEAP-1A projects slightly shortened by 2%. Meanwhile, PW1100 and PW1500 rental durations decreased by 16% and 2%, respectively.

Engine stand rental periods for widebody engines PW4000-94 surged by 262%, while Trent700 leases shortened by 17%.

Hanna Lavinskaja, Head of EngineStands.com, elaborated on this data and its implications for the engine maintenance industry:

"Our 2025 figures clearly reflect the pressures our customers faced last year across the engine maintenance ecosystem, including longer shop visit turnaround times, tighter MRO capacity, and more intensive maintenance events.
