1. Global Expansion of Airports
New terminals, advanced facilities, and expanding passenger traffic are fueling demand for on-site and off-site MRO hubs.
Example: Air India launched new MRO services at Kempegowda International Airport (Bengaluru) in 2024.
Ethiopia is building a mega airport to handle 60M travelers annually by 2040.
2. Rising Investments in New MRO Facilities
Global aerospace giants are investing in cutting-edge MRO hubs.
Example: In 2025, Thales Group opened a state-of-the-art MRO center in Gurugram, India, offering advanced repair capabilities.
3. Safety Regulations & Lifecycle Management
Regulators worldwide mandate regular checks, overhauls, and certifications, making MRO an essential—not optional—investment.
4. Technological Innovations
New aircraft technologies like fuel-efficient turbofan engines, foldable wings, and electric aircraft (eVTOLs) demand next-gen MRO solutions.
High Costs: Repairing a wide-body jet engine can cost USD 5M–12.5M.
Skilled Labor Shortage: MRO requires specialized engineers and technicians, increasing operational expenses.
Downtime Challenges: Extended maintenance can ground aircraft, leading to lost business hours and revenue.
Next-Gen Aircraft: New designs like JetZero’s blended-wing aircraft (ordered by United in 2025) create opportunities for specialized MRO solutions.
Digital MRO (Smart Tech): AI-driven predictive maintenance, digital twins, and IoT-based monitoring reduce downtime.
Sustainability Focus: Airlines and MRO providers are embracing eco-friendly practices, optimizing fuel efficiency and recycling materials.
Asia-Pacific Growth: With increasing fleets in India, China, and Southeast Asia, APAC is set to become the fastest-growing MRO hub.
