The aviation industry is entering a period of sustained growth. According to IATA’s December 2025 Global Outlook, global passenger traffic is forecast to rise 4.9% in 2026, with industry revenues projected to exceed $1 trillion for the second consecutive year. For fleet operators across commercial aviation, military aviation, and business aircraft sectors, this expansion signals both opportunity and urgency, particularly when it comes to aircraft maintenance readiness.
The aircraft maintenance, repair, and overhaul (MRO) services provider industry is keeping pace. Analysts project the MRO market will reach approximately $97 billion in 2026, up from $91 billion in 2025. Additionally, aging fleets, delivery backlogs, a deepening labor shortage, and supply chain volatility are reshaping how operators manage maintenance costs and flight operations. For operators and Directors of Maintenance (DOMs), understanding the key dynamics in play is essential to optimize operational efficiency and fleet availability.
The State of Global Fleet Growth
The global commercial aircraft fleet now comprises approximately 35,550 passenger aircraft, including 30,300 active units and 5,250 held in storage, according to IATA’s August 2025 fleet analysis. While these numbers reflect a robust air transport sector, they also reveal significant structural challenges affecting the aviation sector worldwide.
Delivery Shortfalls and Aging Fleets
New aircraft deliveries are not keeping pace with increasing demand. IATA reports that approximately 5,284 fewer aircraft were delivered between 2019 and 2026 than pre-pandemic projections anticipated. This delivery shortfall has forced airlines to extend the operational life of existing aircraft, pushing the average fleet age to 15 years—up from 13 years before COVID-19.
Key factors driving this gap include:
- Production bottlenecks at major airframe manufacturers
- Quality control issues delaying final delivery
- Component and engine shortages affecting assembly timelines
- Supply chain disruptions limiting access to critical materials
Passenger Traffic Growth
Despite these constraints, air travel continues its rapid growth trajectory. Key figures include:
- 5.2 billion passengers expected globally in 2026, a 4.4% increase from the prior year
- Asia-Pacific leading global passenger traffic growth, driven by strong domestic markets and rising international demand
- North America facing capacity limitations tied to aircraft availability
- Middle East and European Union markets maintaining steady expansion
- United Kingdom seeing continued recovery in both domestic flights and international routes
For operators across the aviation industry, the implications are clear: fleets are accumulating more flight hours than ever before. This increased utilization translates directly into greater demand for aircraft maintenance services across all aircraft types and aircraft systems.
MRO Market Expansion and the “Super Cycle”
The combination of aging fleets, delivery delays, and heightened aircraft utilization has created what industry analysts describe as the MRO “Super Cycle” — a prolonged period of elevated demand for maintenance, repair, and overhaul services affecting every segment of the airline industry.
Market Size and Growth Projections
The commercial MRO market stood at approximately $96 billion in 2025 and is forecast to grow at a compound annual rate of nearly 5% through the end of the decade. This represents the largest market expansion in the sector’s history.
Current market dynamics indicate:
- Engine overhauls will remain the largest spending category, accounting for approximately 47% of total MRO market share
- Component MRO services are experiencing significant increases in demand due to parts scarcity
- Avionics and aircraft systems repairs are gaining importance as fleets age
Load Factors and Utilization Pressure
Increasing demand requires airlines to fly fuller planes more often than ever before. Record-high load factors means that aircraft spend more time in the air and less time on the ground—accumulating flight hours faster and accelerating wear on aircraft systems. For maintenance teams, this translates to tighter turnaround windows and increased pressure to keep fleets operational without delays.
Regional Market Dynamics
The aviation market is growing across all major regions, though at different rates:
- Asia-Pacific is the fastest-growing MRO region, driven by rapid fleet expansion and government investment in domestic maintenance capabilities
- North America remains the largest market, anchored by major airlines and a strong domestic market
- The Middle East continues investing heavily in MRO infrastructure to support its global hub strategy
- European Union maintains steady demand, shaped by established airline networks and regulatory oversight from the European Commission
- Latin America and Africa present emerging opportunities as airlines modernize aging fleets
Key Challenges Facing the Aviation Sector
Labor Shortage Crisis
The general aviation and commercial aviation maintenance workforce faces a generational shift that threatens operational efficiency across the aviation industry. According to Boeing’s 2025 Pilot and Technician Outlook, the industry will need 710,000 new maintenance technicians globally over the next 20 years to support air transport operations.
Current Workforce Gaps
- The labor shortage is already affecting day-to-day flight operations. The industry saw a 10% shortage of certificated mechanics in 2025.
- The workforce is also aging rapidly. More than a quarter of current mechanics are over age 64, and an estimated 80% of today’s technicians are expected to retire within the next five to six years. Simply put, experienced technicians are leaving faster than new ones are entering the field.
Impact on Operations
This imbalance is creating ripple effects across the aviation sector. Operators are seeing longer lead times for both scheduled and unscheduled maintenance. Competition for skilled technicians is intensifying among airlines, MRO providers, and OEMs — driving up wages and making it harder to staff critical roles.
For operators, the takeaway is clear: MRO partnerships that can deliver consistent, timely service are more valuable than ever.
Supply Chain Volatility
Supply chain constraints continue to limit fleet renewal and parts availability, directly impacting maintenance costs and operational efficiency.
Aircraft Backlog and Delivery Delays
The current state of new aircraft orders presents significant challenges:
