1. Introduction: Why Aircraft MRO Matters

Aircraft MRO is one of the most critical components of the aviation value chain. Every aircraft must undergo routine inspections, repairs, component replacements, and periodic overhauls to maintain safety and performance. Airlines spend between 10%–15% of their total operating expenses on maintenance, underscoring the sector’s financial significance.

Whether it's heavy checks on wide-body jets or line maintenance for short-haul aircraft, MRO ensures:

• Passenger safety
• Regulatory compliance
• Optimal fuel efficiency
• Reduced downtime
• Extended aircraft lifespan

As global air travel rebounds and new aircraft technologies enter fleets, demand for advanced, efficient, and sustainable MRO services is poised to grow steadily.
