Estimated at $49 billion, the global aircraft maintenance, repair and overhaul (MRO) market is highly fragmented with over a hundred participants.

The North American aircraft MRO market is outsourcing almost 55 percent of commercial aircraft MRO work. The figure is closer to 100 percent for business and regional jets.
