Component Traceability Requirements for Life Limited Parts
ARP6943
This document contains the recommended practices for the traceability of civil aircraft life limited parts. 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 providing 'back to birth traceability' is provided.
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' traceability is required there is not an international agreement on the recommended practice for providing and maintaining this data.
