The Asia-Pacific region has a total of 116 fixed-wing and 136 rotary-wing maintenance, repair and overhaul (MRO) facilities. However, not all of these facilities have the same level of authorization and have been classified differently:
- AUTHORIZED SERVICE FACILITY (ASF): An authorized service facility is defined as an organization that has been deemed qualified by the Original Equipment Manufacturer (OEM) to perform maintenance, repair operations and alterations on an aircraft, airframe, or any part for which it is related and within the terms and conditions with the OEM. The degree of maintenance (line, base or both) that the ASF can perform for any aircraft is determined by the OEM. Each ASF has a special relation with an OEM to provide the same level of maintenance, for which they are authorized, with the additional convenience of being local.
- ORIGINAL EQUIPMENT MANUFACTURER OWNED (OEM): OEM facilities are maintenance and repair facilities that have been set-up in different countries to provide factory level MRO services to operators locally. These facilities are owned by the OEMs themselves and thus have many benefits over other facility types -faster procurement and replacement of damaged parts, factory-level guaranteed service, etc.
- THIRD PARTY: Third-Party facilities are neither owned by the OEMs nor have the authorization to provide maintenance and repair services by the OEMs. Although not directly authorized by the OEM, these facilities have the capabilities to provide maintenance services locally and generally at a lower cost.
The following section provides a breakdown by OEM of the different MRO facilities and their capabilities in the Asia-Pacific region.
