Which of the following items are NOT authorized in phase maintenance kits?

Phase maintenance kits are specifically designed to contain items that are essential for completing maintenance tasks efficiently while adhering to the guidelines set forth by the Navy's logistical support systems. AVDLR items, which stand for Afloat and Variable Depot Level Repairables, represent a category of items that typically include repairable components that are essential for the maintenance and repair of equipment but are not meant to be included in phase maintenance kits.

Including AVDLR items in phase maintenance kits could lead to logistical complexities, as these items generally require different handling, tracking, and management than commonly used tools, inspection materials, and replacement parts. The main purpose of phase maintenance is to have readily available resources that support regular maintenance cycles, while AVDLR items can often be sourced from specific supply chains or are associated with depot-level activities, which don't align with the immediate needs of phase maintenance. Therefore, identifying AVDLR items as unauthorized in these kits keeps the focus on streamlining maintenance operations with the appropriate tools and materials required for routine tasks.
