The Current State of Engine MRO
The aviation world is dealing with some massive engine shop backlogs this year, fueled by a huge spike in demand for maintenance, repairs, and overhauls. It’s all because of ongoing supply chain snags, not enough hands on deck, and aircraft deliveries that keep getting pushed back. You see headlines screaming about “record-high turnaround times,” but when you look closer, there’s not much solid data comparing shops by location, engine model, or what they can handle. That’s where this article comes in—breaking it down with real numbers on TATs and available spots for narrowbody versus widebody work.
From a 2024 engine maintenance report, MRO demand will top out next year, potentially outstripping what’s available by as much as 17%, and these headaches aren’t going away anytime soon. This comes after the pandemic bounce-back, where new engines are taking 150% longer to service than before 2019, and older ones are up by about 35%. Another forecast for 2025 on fleets and MRO sees the whole market reaching $119 billion this year, climbing at 2.7% yearly to hit $156 billion by 2035. Narrowbodies—like those powering A320neos and 737 MAXes—grab nearly half the pie at 48.7%, with engine services leading the pack at 31.4%.
So why’s the data so spotty? A lot of these reports lump everything together, hiding how things differ from one region to another or by specific engines. Take Asia-Pacific: they’re slammed with shortages in local facilities, pushing TATs up 75% for parts across the board. From airline contracts, we know there are around 17,000 planes still waiting to be handed over worldwide, so operators are hanging onto older engines longer, which just pumps up the MRO queue. Job ads are a sneaky good indicator too—a recent MRO poll calls out tech shortages as the biggest pain point, with shops scrambling to hire and add capacity, like the 2,500 new roles tied to engine fixes.
This year, the global MRO tab is expected to ring up at $120.1 billion, and half of that’s going to engine overhauls. But wages for labor are jumping 5.8%, and parts are still hard to come by. All this means longer waits: narrowbody engines have lines stretching for months, and widebodies? Even tougher, since there aren’t as many shops equipped for them.
Narrowbody Engine MRO: High Demand and Delays
Narrowbody engines—the CFM LEAP, PW1000G series (that’s the GTF), and classics like the CFM56—are getting hammered by these backlogs, mostly because they’re everywhere in short-haul ops. The market for narrowbody MRO is booming, especially with budget airlines growing their fleets, but the shops can’t keep up. Figures show TATs for modern ones like the LEAP running 150-200 days now, way up from the 100-120 days we saw before the pandemic—that’s a 150% jump. Older models like the CFM56 are at 120-150 days, a solid 35% increase.
Those LEAP delays are really stinging in 2025. CFM’s gearing up to crank out 15-20% more, aiming for over 2,000 engines a year, but stuff like turbine blade wear is grounding planes left and right, dragging out repairs. One report from this year talks about extended waits for LEAP parts, things like those fancy ceramic composites, bumping TATs to 180-240 days. Safran’s pushing to sort out Airbus delays by October, but the lines are still long everywhere. And don’t forget the thousands of inspections needed for LEAPs and GTFs—that’s just adding more pressure.
Here’s how the major global MRO shops stack up for narrowbodies, based on TATs and open slots from various surveys (shorter times and more spots mean higher ranks):
- Pratt & Whitney (North America/Asia): Around 120-150 days for GTF work; they’re boosting production 30% this year with fresh sites in China and the U.S., getting availability up to 70-80%. Job listings show over 500 new hires, which screams expansion.
- CFM International/Safran (Europe/Asia): 150-200 days on LEAPs; slots at 60-70% while they fix durability glitches. They’re eyeing 2,000 overhauls for 2025, though holdups linger.
- StandardAero (North America): 130-180 days for CFM56 and LEAP; about 65% open. They just added 80,500 square feet to their Augusta spot, freeing up more room.
- MTU Aero Engines (Europe/Asia): 140-190 days; availability 55-65%. They’re solid on LEAP stuff and looking at 2,500 jobs from repair work.
- ST Engineering (Asia-Pacific): 160-220 days; only 50% slots free, thanks to local squeezes. They’re huge in airframes but engines are bottlenecked; job posts are up 20% to build out.
Regionally, Asia-Pacific’s got it worst, with TATs 20-30% longer than North America’s due to thin capabilities. Europe’s doing okay at 70% availability.
Widebody Engine MRO: Scarcer Slots and Longer Waits
Widebody powerplants, think GE90, Trent family, or GP7200, handle the long-distance stuff—with fewer engines out there but way more complexity, so slots are tight. The widebody MRO scene’s pegged at $27.21 billion for 2025, set to grow to $39.07 billion by 2034 at 4.1% a year. Average TATs are 180-250 days now, compared to 120-150 before the pandemic. Supply chains are shifting gears, and waits for widebody jobs can drag on 6-9 months.
Rolls-Royce is wrestling with Trent backlogs; their TotalCare deals cover 80% of fleets but lock out independents a bit. GE’s GE90 fixes are hitting 200+ days with part shortages. Widebodies are where the growth is coming, but right now, capacity’s the issue.
Rankings for widebodies:
- GE Aviation (North America/Europe): 150-200 days; 75% availability. They’re tops on GE90 and using airline pacts to clear queues quicker.
- Rolls-Royce (Europe/Asia): 160-210 days; 65-70% slots. TotalCare Life gives some stability, but new tech delays push into the mid-2030s.
- Lufthansa Technik (Europe): 170-220 days; 60% open. They’re pros at widebody work.
- HAECO (Asia-Pacific): 180-240 days; 55% availability. Tied to Swire Pacific, they manage up to 44 widebodies but region’s holding them back.
- AAR Corp. (North America): 190-250 days; 50-60% free. Polls point to part shortages, but they’re hiring to fix it.
North America’s ahead with 3.45% growth yearly to $31.94 billion by 2030, while Asia trails.
Reasons for Backlogs and Future Outlook
These jams come from OEM slowdowns—like GE’s troubles with F-404/414 or PW’s camshaft issues—plus the worker shortage. Job openings for MRO pros are spiking, with over 123 in the U.S. alone. Moves like StandardAero’s expansions offer some hope, but 2026 could still be rough.
This year, tools like AI and live data might shave TATs by 23%, based on some examples. Still, if we don’t get better, more detailed surveys to close the data holes, airlines could face downtime that costs a fortune.
Conclusion
The 2025 engine shop backlog is a real, numbers-backed nightmare, with sky-high TATs and slim pickings for slots—worst for LEAP fixes and widebodies. Ranking outfits like Pratt & Whitney and GE as the efficiency champs helps plug that info gap. With MRO expanding into double digits, everyone involved needs to pour money into more staff and smarter tech to dodge a bigger mess by 2030.
