When an aircraft component needs replacement of a serially controlled item, a maintenance officer in the U.S. Navy uses the Scheduled Removal Component (SRC) card to confirm the component’s life cycle, to verify that the part is ready-for-issue, and to verify how many flight-hours it still has left. Unfortunately, replacement components are often missing the SRC cards. Further, when the cards are received simultaneously with the aircraft component requiring replacement, their encoded data are unreliable, which then precludes the part from being immediately installed. In this article, the authors analyze the impact of current paper-based life-cycle management of serially controlled parts, and investigate item-unique identification and radio-frequency identification technologies as alternative ways of tracking these parts to increase operational availability.
