GM1 145.A.55(a)(1) Record-keeping ED Decision 2022/011/R MAINTENANCE RECORDS 1. Properly executed and retained maintenance records provide: (i) owners and persons or organisations responsible for aircraft continuing airworthiness with information essential in establishing the airworthiness status of aircraft or component, and in particular, in controlling unscheduled and scheduled maintenance; (ii) maintenance personnel with information essential for troubleshooting eliminating the need for re-inspection and rework. The prime objective is to have secure and easily retrievable records with comprehensive and legible contents. The aircraft record should contain basic details of all serialised aircraft components and all other significant aircraft components installed during the maintenance performed, to ensure traceability to such installed aircraft component documentation, associated maintenance data and data for modifications and repairs. 2. Some gas turbine engines are assembled from modules, and a true total time in service for a total engine is not kept. When it is desirable to take advantage of the modular design, then the total time in service and the maintenance records for each module are to be maintained. The maintenance records as specified are to be kept with the module and should show compliance with any mandatory requirements pertaining to that module. ##### GM1 145.A.55(a)(1) Record-keeping *ED Decision 2022/011/R* **MAINTENANCE RECORDS** 1.
