From PW1100G to CFM56: The Engine Maintenance Trends Shaping 2026
The first half of 2026 brought encouraging announcements from aircraft and engine manufacturers. GE Aerospace reported strong growth in commercial engine deliveries, Airbus continued expanding A320 Family production capacity, and Pratt & Whitney announced further investment in its GTF maintenance network.
Despite these positive developments, engine MRO bottlenecks and aerospace supply-chain constraints remain among the industry’s most pressing challenges, affecting both legacy and new-generation fleets.
EngineStands.com operational data provides an additional perspective on these market dynamics. During the first half of 2026, leasing volumes increased, customer activity diversified, and project durations began moving in different directions across engine programs.
Together, these trends illustrate how the pressures facing manufacturers, airlines, and MRO providers are translating into demand for the physical infrastructure required to remove, transport, store, and maintain aircraft engines.
PW1100G Demand Remains the Strongest Market Signal
PW1100G stands recorded the highest utilization level across EngineStands.com portfolio during the first half of 2026, reaching 95%, reflecting continued pressure from Pratt & Whitney’s GTF inspection and maintenance program.
Although MRO throughput improved and aircraft groundings declined by approximately 15%, the program continues to generate significant volumes of engine removals, inspections, and shop visits. During the first half of 2026, EngineStands.com leasing volumes for PW1100G stands exceeded total volumes recorded throughout all of 2025, while average project duration dropped from 245 days in 2024 to 123 days.
This shorter cycle time improves asset efficiency, but it also increases risk. Stands must be returned, inspected, and redeployed faster, leaving less room for delays caused by transportation, customs, repairs or extended maintenance events.
Legacy Narrowbody Engines Continue to Absorb Capacity
Continued reliance on mature narrowbody fleets remains another major driver of engine stand demand.
EngineStands.com data shows:
- CFM56-5A/B utilization reached 92% in the first half of 2026, up from 77% in 2025.
- CFM56-7B utilization remained high at 77%, while average project duration shortened by approximately 17%.
- V2500 utilization increased to 76%, but its project durations lengthened by roughly 9%, suggesting that some maintenance events are becoming more complex and take longer to complete.
These engine families continue to power the Airbus A320ceo and Boeing 737 Next Generation fleets, which together account for roughly 60% of the global in-service fleet. Airlines remain heavily dependent on these aircraft as new aircraft deliveries are insufficient to meet market demand and production backlogs stretch years into the future.
As a result, stand demand for mature engine programs is not being replaced by LEAP and GTF activity. Instead, both generations are drawing on the maintenance ecosystem at the same time.
LEAP Stand Demand Is Entering a More Mature Phase
Improving LEAP production is supporting higher aircraft delivery volumes, but it does not eliminate aftermarket demand.
As the installed base of LEAP-1A and LEAP-1B engines continues to grow, more engines are entering scheduled and unscheduled maintenance cycles. Durability modifications, removals and early-life shop visits are gradually increasing the demand for OEM-certified engine stands.
LEAP-1A stand utilization remained strong at 71% during the first half of 2026. Average project durations shortened by approximately 8%, reflecting faster stand turnover and the continued implementation of engine durability improvements.
LEAP-1B followed a different pattern. Average project durations increased by approximately 5%, consistent with a program entering a more active maintenance phase as the Boeing 737 MAX fleet accumulates more cycles.
Trader Activity Is Changing the Demand Profile
The customer mix recorded during the first half of 2026 also provides insight into how the engine aftermarket is developing.
Airlines continued to generate demand across a broad range of engine programs, including CFM56-5A/B, CFM56-7B, V2500, LEAP-1A, LEAP-1B and PW1100G. Their activity reflects the need to manage both aging narrowbody fleets and maintenance events affecting newer-generation engines.
Lessors were particularly active across LEAP-1A, PW1100G and V2500 programs, as well as the Trent 700 widebody market. Engine stands support a variety of asset-management activities, including maintenance preparation, engine transitions, repossessions, inspections and storage.
MRO demand remained concentrated around selected narrowbody platforms and the Trent 700, consistent with continued shop-visit backlogs and increasingly complex maintenance scopes.
However, the most active customer category during the first half of 2026 was engine traders. Activity centered primarily on CFM56-7B, PW1100G, and V2500 engine stands, reflecting continued growth in engine transactions, teardown activity, short-term storage, and asset transitions.
Widebody Engine Support Requires a Different Planning Approach
Although narrowbody programs account for the highest stand utilization, widebody engine activity continues to create distinct operational requirements that operators should not overlook.
During the first half of 2026, Trent 700 and CF6-80E demand remained closely linked to MRO providers, lessors, and engine asset transitions. These engines continue to support a large global Airbus A330 fleet operating across passenger, cargo, government, and charter missions.
Widebody engine shop visits are often concentrated within a smaller number of specialized overhaul facilities, meaning engines travel farther and remain in transit longer than their narrowbody counterparts. This requires closer coordination between operators, freight providers, and MRO facilities to manage transportation timelines, engine stand availability, and maintenance schedules effectively.
Preparing for the 2026 Peak Maintenance Cycle
This summer is proving to be the industry’s stress test. Peak schedules, high load factors, and elevated fuel costs leave airlines with little room for disruption, making every grounded aircraft increasingly expensive to recover.
The impact of that utilization will not disappear once the summer peak ends. For example, a Boeing 737NG flying five to six cycles per day can consume a full 450-cycle task interval in a single summer season. Similarly, an Airbus A320 flying 8 to 10 hours per day can consume a 750 flight-hour light check interval in just 75 to 94 days.
This accelerated utilization drives additional inspections, servicing, and rectification work across the fleet. The pressure becomes most apparent during the autumn maintenance season, when airlines compete for limited repair capacity, labor, and constrained parts availability, resulting in longer lead times and increased component costs across the supply chain.
As more aircraft enter maintenance and engine removals accelerate, demand for engine stands is expected to rise accordingly. Airlines, MRO providers, lessors, and engine traders will increasingly compete for the same pool of available equipment as maintenance activity reaches one of its annual peaks.
Therefore, engine stand availability should be treated as a key element of maintenance planning rather than a last-minute logistics requirement. Securing stands in advance reduces the risk of project delays, transportation disruptions, and unnecessary aircraft downtime while helping operators maintain predictable maintenance schedules.
