Which term refers to repair parts used to restore end items?

The term that refers to repair parts used to restore end items is "Components." In logistics and maintenance management, components are specific parts or elements of a system that can be replaced to repair or restore the functionality of an item. They are integral to the repair process, as they directly contribute to the operational capabilities of the end item.

Components are typically hardware parts such as circuit boards, engines, or mechanical assemblies that, when replaced or repaired, bring the end item back to an operational state. This distinguishes them from the other terms: materials generally refer to substances used in the production processes, accessories are additional items that enhance the functionality or usability of the main item without being essential, and consumables are items that are used up in the process or have a limited lifespan and are not necessarily intended to restore functionality directly. Understanding the role of components is crucial for effective maintenance and support operations in the Army.
