Global aviation enters a new era where skilled technicians, digital expertise and advanced maintenance capabilities will determine the industry’s ability to support a rapidly expanding fleet. Boeing’s latest 20-year outlook highlights why the future of aviation will be shaped as much by people as by aircraft.
The commercial aviation industry is preparing for its next major growth cycle, but this time the greatest challenge may not be manufacturing enough aircraft; it will be finding enough qualified professionals to keep them flying.
In its latest Services Market Outlook (SMO) and Pilot & Technician Outlook (PTO), released ahead of the Farnborough International Airshow 2026, Boeing forecasts a US$4.9 trillion global aviation services market over the next two decades, accompanied by demand for more than 2.4 million new aviation professionals through 2045.
For the MRO industry, however, one figure stands above all others. The global aviation ecosystem will require approximately 728,000 new aircraft maintenance technicians over the next twenty years, a workforce expansion that reflects not only unprecedented fleet growth but also the increasing technological complexity of modern commercial aircraft.
As airlines introduce highly digital aircraft, advanced engines, connected maintenance systems and predictive diagnostics, the role of the aircraft maintenance engineer is undergoing its most significant transformation in decades.
Most critical resource
Aircraft have become significantly more sophisticated over the last decade. Composite structures, integrated avionics, digital flight systems, health monitoring technologies, predictive maintenance platforms and next-generation propulsion systems have dramatically increased maintenance complexity. Consequently, the future technician will require expertise that extends well beyond conventional mechanical maintenance.
According to Boeing’s outlook, airlines and MRO organisations worldwide will require 728,000 newly trained maintenance technicians by 2045, making technical workforce development one of the industry’s most pressing strategic priorities.
Importantly, the demand is not being driven solely by fleet expansion. Nearly two-thirds of all new aviation professionals will replace experienced personnel reaching retirement, while only one-third will support growth in global aircraft fleets. For maintenance organisations, this represents a significant knowledge transition as decades of practical engineering experience leave the industry over the coming years.
$4.9 Trillion opportunity
Boeing estimates the commercial aviation services sector will generate approximately US$4.9 trillion in demand between 2026 and 2045.
The services ecosystem extends far beyond traditional heavy maintenance, encompassing: aircraft maintenance, repair and overhaul, engine maintenance and performance optimisation, digital fleet support, spare parts management, component repair, engineering services, flight operations support, aircraft modifications, technical training, predictive maintenance solutions, data analytics and digital fleet management. As fleets become increasingly connected, software-driven and data-intensive, digital services are expected to account for a growing share of the aftermarket.
For MRO providers, competitive advantage will increasingly depend on the ability to combine engineering expertise with advanced digital capabilities.
Digital aircraft demand digital engineers
Perhaps the most significant theme emerging from Boeing’s outlook is the rapid digitalisation of aviation maintenance. Modern aircraft continuously generate operational and health-monitoring data, allowing airlines to predict component failures before they occur. Instead of relying solely on scheduled inspections, operators are progressively adopting condition-based and predictive maintenance strategies.
This evolution is fundamentally changing the role of maintenance personnel. Tomorrow’s licensed aircraft engineers must understand not only aircraft structures and propulsion systems, but also digital diagnostics, software-enabled maintenance planning, aircraft connectivity and data interpretation.
The maintenance hangar is becoming as much a digital operations centre as it is a traditional engineering facility.
Aircraft lifecycle management
Efficiency remains one of the defining themes of Boeing’s forecast. Rather than focusing exclusively on new aircraft acquisitions, airlines are increasingly managing assets across their entire operational lifecycle.
Lifecycle management now encompasses predictive maintenance, engine health monitoring, component reliability analysis, digital records management, sustainability initiatives and operational optimisation.
For MRO organisations, this means expanding from maintenance execution to becoming strategic lifecycle partners capable of improving aircraft availability, reducing downtime and lowering total ownership costs.
Sustainability is reshaping maintenance practices.
Environmental objectives are also influencing the future services market.
Fleet renewal, fuel-efficient aircraft, sustainable aviation fuel compatibility and extended component life are becoming integral parts of airline maintenance strategies.
MRO providers are responding through advanced repair techniques, component refurbishment, circular economy programmes, material recovery, engine performance restoration and digital maintenance planning that reduces unnecessary removals
Maintenance is increasingly recognised as a contributor to both operational efficiency and sustainability performance.
New training model
Beyond forecasting personnel demand, Boeing emphasises that aviation training itself must evolve. Traditional classroom-based instruction is gradually being complemented by immersive technologies including virtual reality, augmented reality, digital simulation and interactive maintenance environments.
These technologies support Competency-Based Training and Assessment (CBTA), enabling technicians to gain practical experience in complex maintenance scenarios before working on live aircraft.
Chris Broom, Vice President of Commercial Training Solutions at Boeing Global Services, noted that immersive technologies will play a critical role in preparing the next generation of aviation professionals while maintaining the industry’s high safety standards.
For MRO organisations, investment in digital learning platforms and continuous professional development will become essential as aircraft technologies continue to evolve.

Regional workforce demand
Boeing’s regional forecast illustrates where maintenance capability will be most needed over the coming decades. Globally, demand includes 674,000 new pilots, 728,000 maintenance technicians, and 1.023 million cabin crew.
Together, these roles account for more than 2.4 million new aviation professionals by 2045.
Among the fastest-growing markets, China is projected to require 131,000 maintenance technicians, while Eurasia will need approximately 169,000 technicians, reflecting the scale of fleet expansion across those regions.
Closer to home, South Asia is forecast to require around 48,000 new aircraft maintenance technicians, alongside 48,000 pilots and 54,000 cabin crew, representing a total workforce demand of approximately 150,000 new aviation professionals. Boeing estimates the region’s commercial aviation services market will be worth around US$220 billion by 2045.
These projections reinforce South Asia’s growing importance as both an aviation market and a strategic centre for maintenance, engineering and technical support services.
The Future MRO Engineer Will Combine Engineering with Digital Intelligence
The aircraft maintenance technician of 2045 will operate in a vastly different environment from today’s engineer. Artificial intelligence, predictive analytics, digital twins, remote diagnostics, connected aircraft and automated maintenance planning are expected to become standard industry tools.
Future engineers will increasingly interpret operational data, optimise maintenance schedules, collaborate with software platforms and support integrated fleet management systems.
Mechanical expertise will remain fundamental, but digital competency will become equally important.
People will define aviation’s next growth cycle.
Boeing’s latest outlook reinforces an important reality for the global aviation industry. While new aircraft programmes, advanced propulsion systems and sustainable technologies will continue transforming commercial aviation, none of these innovations can deliver their full potential without a sufficiently skilled workforce to maintain them safely and efficiently.
The forecast demand for 728,000 new maintenance technicians is therefore more than a workforce statistic; it is a strategic warning and an opportunity.
For airlines, OEMs, regulators, training institutions and MRO organisations, investment in technical talent, digital skills and continuous professional development will be just as critical as investment in hangars, tooling and infrastructure.
As the global fleet expands and aircraft technologies become increasingly sophisticated, the future competitiveness of the aviation aftermarket will ultimately be determined not by the number of aircraft in the sky, but by the expertise of the professionals keeping them there.
