Which of the following describes Class X items?

Class X items refer specifically to repairable items that are not directly maintained on the aircraft. This classification is important in logistics and supply chain management, particularly in the context of maintaining military or other types of equipment. These items generally support the aircraft's operational capability but do not form part of the aircraft itself during its operation.

In understanding the broader context, Class X items often include components that can be sent off for repair rather than replaced, allowing for cost-effective and efficient maintenance practices. By ensuring that logistics operations keep a robust supply of these repairable items, organizations can significantly reduce downtime and enhance overall mission readiness. The focus on these items emphasizes the balance between keeping operational fleets functional and managing inventory effectively.
