The aviation maintenance sector is expanding, but industry survey data show that labor and material shortages remain the constraints most likely to hold it back. As global MRO demand climbs toward roughly $140 billion in 2026, providers report that finding enough qualified technicians and securing enough parts are the persistent challenges shaping their operations.

Workforce sits at the top of the list. Experienced mechanics are retiring faster than new technicians enter the field, leaving a widening skills gap at exactly the moment maintenance volumes are rising. The pressure has pushed carriers and independent shops to build direct pipelines into technical training programs, competing to secure graduates before they reach the open labor market.

Supply chain conditions compound the strain. Respondents pointed to material shortages alongside geopolitical instability and tariffs as leading disruptors, factors that lengthen turnaround times and raise costs. When parts are delayed, aircraft sit longer in maintenance, reducing the availability airlines count on and rippling through flight schedules.

The fleet backdrop intensifies the demand. With the average commercial aircraft now older than in prior years, more jets require heavy checks and component work, adding to the workload just as capacity is stretched. Newer engine platforms experiencing durability issues have added unplanned maintenance events on top of scheduled work.

The result is a sector defined by a gap between opportunity and capacity. Demand is strong and growing, yet the ability to meet it hinges on resolving the workforce and supply constraints that survey after survey has flagged as the industry's central problem.
