Increasing global air traffic is pushing the MRO market in Commercial Aviation.

Compared to other aerospace sub-segments, it can be said that Maintenance , Repair and Overhaul (MRO) segment attracts less investment in technology and facilities. However, MRO is a serious business activity which is highly capital intensive in terms of financial outlay, creating cost efficient models and deliverables. There are basically three types of service providers in the MRO market. These are Aircraft Operators, Original Equipment Manufacturers (OEMs) and Independent Service Providers. The global civil aviation MRO market is estimated to worth more than $45 billion in 2011.Due to the financial crisis, global air transport MRO spending decreased about $2.5 billion from 2007 to 2009. North American carriers experienced the largest capacity reduction on record in 2008, when U.S. carriers reduced capacity by nearly 800 aircrafts. The need to save costs has halted airline fleet expansions, with aircraft maintenance outsourcing expected to hold steady. However, increasing global air traffic is pushing the  MRO market in commercial aviation to grow. By 2019 total size of the market is estimated to reach to  60 billion USD.
