Component Traceability Requirements for Life-Limited Parts
ARP6943
This document contains the recommended practices for the traceability of civil aircraft life-limited parts (LLPs) applicable to landing gears. A unified means of tracking flight cycles, flight hours, and calendar time is provided, which will ease the interchange of parts between companies and through the component’s life cycle. A harmonized means of defining “back-to-birth” (BtB) traceability is provided to ensure airworthiness of service LLPs.
Rationale:
Civil aircraft components such as landing gears which are removed from aircraft for overhaul or exchange onto other aircraft must be traced - the aircraft, consumed life, maintenance, repair, and incident history must be maintained to provide correct evidence of the usage history of the component. While all companies agree that back-to-birth (BtB) traceability is required, there is not an international agreement on the recommended practice for providing and maintaining this data.
