COMAC collects information on MROs (Maintenance, Repair, and Overhaul) that have the capability to perform airframe maintenance for specific aircraft models, compiles an airframe MRO list, and publishes it to customers.

The service is provided in the form of a service letter (SL), distributed to customers through the Customer Information System (CIS) platform.

To help customers easily obtain information on MROs with the capability for airframe maintenance, COMAC gathers the basic information and contact details of relevant MROs and compiles the airframe MRO list, allowing customers to choose the most suitable service provider.

The goal of this service is to help customers select the appropriate airframe maintenance service provider. Customers benefit by having convenient access to the necessary maintenance services for their aircraft.
