The Evolution
The MRO market has evolved in line with the aviation industry’s growth and modernization:
1950s–1970s: MRO services were mainly provided in-house by airlines or military operators. Outsourcing was rare, and maintenance standards varied across regions.
1980s–1990s: Rapid globalization of air travel and liberalization of aviation policies created the first wave of specialized third-party MRO providers.
2000s: Airlines began outsourcing non-core services to independent MRO companies to reduce costs. OEMs like Boeing and Airbus expanded their aftermarket services.
2010s: Digital technologies such as predictive maintenance, IoT, and big data analytics reshaped how MROs track performance and anticipate repairs.
2020s: The COVID-19 pandemic disrupted demand temporarily, but it also accelerated digital adoption, automation, and new efficiency models in MRO operations.
Today, the market is moving toward sustainable practices, automation, and predictive analytics, marking a new era of transformation.
