The standard maintenance program is based on the maintenance outline approved by the aviation authorities and is used to guide the scheduled maintenance tasks required during the operation of the aircraft. It includes the tasks and intervals required throughout the aircraft’s lifecycle and serves as a planned maintenance document to ensure the aircraft's continued airworthiness and safety. Airlines can use the standard maintenance program as a reference to create their own maintenance plans that meet the airworthiness requirements set by the authorities. COMAC provides the electronic version of the standard maintenance program on the CIS platform, regularly updating it for use by airlines. The service content covers the scheduled maintenance requirements for systems/powerplants, structures, L/HIRF, regions, and ALS, as outlined in the maintenance plan, along with related aircraft information such as region numbers, panel cover numbers, working hours, and AMM manual reference task numbers. The goal of this service is to assist customers in developing their own aircraft maintenance plans. Customers benefit from this service by easily creating maintenance plans that comply with regulatory airworthiness requirements, ensuring smooth and efficient maintenance operations.
