What is a characteristic of bench stock items?

The characteristic of bench stock items that is accurately highlighted in the context of maintenance and supply management is that they must be approved by the Aviation Unit Maintenance (AVUM) maintenance officer. Bench stock items are commonly used tools, equipment, or parts that a maintenance organization requires regularly to fulfill its operations efficiently. Because these items are essential to maintenance tasks, receiving proper approval from the AVUM maintenance officer ensures that the items selected for bench stock align with operational needs and that management maintains control over inventory levels.

While some items may indeed be low-cost and predictable in usage, the approval process for bench stock items is crucial for ensuring that the operational capabilities of a unit are supported effectively. This requirement also helps maintain accountability and proper stock levels, avoiding excess or obsolete inventory.
