Key Drivers:

Rising Number of Aircraft Passengers is Propelling the Market Expansion

The demand for air travel is boosted by the growing number of passengers, which raises flight frequency and aircraft utilization. Increased operating stress causes airplane components to deteriorate more quickly, increasing the demand for aerospace maintenance, repair, and overhaul (MRO) services, thus driving the target market growth. The need for regular inspections, part replacements, and system improvements is driven by the need for airlines to maintain safety, compliance, and performance standards. In order to ensure fleet dependability and passenger safety, the aerospace maintenance, repair & overhaul market expands in tandem with the growth of global aviation traffic, particularly in emerging economies.

• For instance, in January 2025, according to the data published by ACI World, Global passenger traffic is predicted to exceed 9.5 billion passengers in 2024, 104% of 2019 levels, surpassing pre-pandemic levels. It is anticipated that Revenue Passenger Kilometers (RPK) would amount to 8.8 trillion (101% of 2019 levels). Global passenger traffic is expected to surpass 12 billion by 2030, mostly due to the expansion of foreign markets, especially in the Middle East and Asia-Pacific regions. It is anticipated that the number of passengers worldwide would double from 2024 to 2042, reaching 19.5 billion total.

Restraints:

The Shortage of Skilled Labor is Hindering the Market Expansion

The lack of competent workers is a major drawback in the aerospace maintenance, repair & overhaul market.  There is a talent shortage in the sector as more experienced experts retire and fewer fresh professionals join the workforce.
