1.2.1.3 Record-keeping requirements for life-limited parts
1.2.1.3.1 Each operator should maintain the current status of life-limited parts. If the operator obtained such parts new from the manufacturer, the current status will be based upon the operator’s in-service history of the part. If the part has been obtained from a previous operator, the current status will be based on the status from the previous operator(s) plus the present operator’s in-service history. The current status of life-limited parts is required upon each transfer throughout the operating life of the part. When such parts are transferred, the previous operator should produce an in-service history for life-limited parts, irrespective of the operator’s governing regulations. When life-limited parts are transferred between operators, a written statement by the previous operator, attesting to the current status of life-limited parts should also be provided.
1.2.1.3.2 When the in-service history required for the establishment of the of current status for life-limited parts are lost or destroyed, an equivalent level of safety may be determined by consideration of other records available, such as technical records, utilization reports, manufacturer’s information or presentation of other evidence. If review of other available documentation reveals significant errors or omissions that prevent the development of a current status for the life-limited part(s), the part(s) in question should be retired from service until the time the history can be rebuilt. It is the operator’s responsibility to notify the regulatory authority when such records are lost or destroyed and to initiate an immediate search for records from which the current status of the life-limited part(s) can be determined.
1.2.1.3.3 Not all life-limited parts will necessarily be marked with part and serial numbers. For aircraft manufactured in the United States, for instance, specific requirements for life-limited parts to be marked with part and serial numbers have only existed since the early 1980s. Operators should be able to track life-limited parts manufactured prior to the early 1980s, although such parts may not be serialized items. Special attention should be paid to parts that can be transferred from one aircraft to another.
1.2.1.3.4 Operators may receive life-limited parts from a repair station that has a system to determine the current status of such life-limited parts. This system should be recognized as a factor in the substantiation of the current status of life-limited parts.
1.2.1.4 Maintenance programme
1.2.1.4.1 The maintenance programme should include the following:
a) Approval. The approval or acceptance of the maintenance programme by the associated regulatory authority should be identified.
b) Traceability. The maintenance programme should be identified and be traceable to its approved minimum requirements standard, e.g. maintenance review board (MRB) report, the manufacturer’s recommended maintenance programme or recommended tasks. In the event that the programme fails to meet the minimum requirement standard, all areas of such differences should be identified and corrective action taken on the aircraft or to the programme as necessary. The minimum standard is understood to mean only minimum required tasks and not the intervals.
c) Documentation. A printed copy of the maintenance schedule should be provided, identifying all tasks and functions in such a manner as to permit traceability to the corresponding work cards. This includes sampling programme tasks.
1.2.1.4.2 The maintenance/inspection programme may change for aircraft transferred from one operator to another. The integration or bridging plan for the two programmes should be presented to the (receiving, if applicable) airworthiness authority.
1.2.1.5 Service bulletins
All service bulletins that have been incorporated should be listed, together with accomplishment dates (date, flight hours, flight cycles, landings, etc. as appropriate). If options are available, the option complied with should also be indicated. When a service bulletin involves recurring action, the times or dates, as applicable, of the last action and the next action due should be provided.
