The dismantling and recycling of retired civil aircraft are important part of the civil aircraft industry chain. China’s civil aircraft dismantling industry is just in its infancy, and a set of systematic and perfect top-level standards, specifications for civil aircraft disassembly and recycling industry have not been established. In recent years, CAAC has just issued an Advisory Circular on civil aircraft dismantling, which is used to regulate the dismantling activities of parts to be returned for use of aircraft dismantling units, promotes the development of the whole domestic aircraft dismantling industry, and ensures the safety of the use of second-hand aviation materials. Combined with the research on CCAR145, AC-145-017 "civil aircraft dismantling" and other related AC, this paper summarizes the airworthiness requirements related to aircraft disassembly, including the requirements for detachable civil aircraft and process management, and the requirements for detachable civil aircraft enterprises. It is applicable to the civil aircraft dismantling activities for the return of disassembled parts to aviation operators, and provides necessary input for subsequent planning and establishment of top-level standards and specifications for domestic civil aircraft disassembly and recycling industry.
