What document must fleet activities submit to request an increase or decrease in the allowance quantity of AVDLR items?

The Adjustment Change Request-Fleet (ACR-F) is the correct document for fleet activities to submit when requesting a change in the allowance quantity of AVDLR (Aviation Consolidated Allowance List - Depot Level Repairable) items. This document specifically serves the purpose of seeking adjustments in allowances that reflect the needs for parts and equipment for effective fleet operations. The ACR-F enables a structured process to address discrepancies in inventory levels and aligns the fleet's operational requirements with supply chain management effectively.

The ACR-F is designed to facilitate communication between fleet activities and the supply system, ensuring that changes are justified and can be tracked. By submitting an ACR-F, fleet activities can support their requests with necessary data and reasoning, which is crucial for making informed decisions regarding inventory management.

In contrast, other options like the Inventory Adjustment Report (IAR) and the Allowance Change Notification (ACN) serve different purposes related to inventory oversight and managing stock levels rather than specifically requesting changes in allowance quantities. The Request for Change (RFC) typically pertains to broader requests for changes in procedures or policies, not specifically tied to inventory allowances.
