OPERATIONAL SUPPORT INVENTORY/FIXED ALLOWANCE

design as the COSAL but is provided to selected shore activities based on mission essentiality, special operational requirements, remoteness from normal sources of supply, and/or a combination of all three. Aviation Consolidated Allowance List The Aviation Consolidated Allowance List (AVCAL), prepared by the Aviation Supply Office (ASO), is a list of aircraft materials, stated in quantities that will satisfy predicted require- ments for maintenance of a specified mix of air- craft for a predetermined period of time. Its purpose is to provide the aviation ship or air station with a tailored list of materials that can be used as a stocking guide. Shore-Based Consolidated Allowance List The Shore-Bared Consolidated Allowance List (SHORCAL), prepared by the ASO, lists repairable items and subassemblies required for a shore station to perform its operational mission in support of assigned aircraft, engines, and end items of support equipment (SE) based on available local repair capability. OPERATIONAL SUPPORT INVENTORY/FIXED ALLOWANCE The operational support inventory (OSI) is a retail stock level comprised of a fixed allowance for DLRs and field level replairables (FLRs) as well as consumables. The OSI is that quantity of pre-positioned material required to support the planned aircraft program and the unique mainte- nance mission assigned to a given activity. Weapons systems are supported under the OSI/fixed allowance concept as outlined in FASOINST 4441.16. A negotiated firm allowance of repairable assets may not be exceeded without ICP authorization. Strict one-for-one exchange procedures between the O- and I-level mainte- nance activities and the supply department must be maintained. Requisitions passed off-station are not authorized before BCM action, except for CRIPL items. All OSI/fixed allowance assets are carried in purpose code W on the supply officer’s records. Storage of fixed allowance assets is authorized at any designated location within an operating site. The fixed allowance concept is designed to guarantee equal distribution of repairable assets and to ensure adequate levels of supply for operating forces as outlined in NAVSUPINST 4440.16. Fixed allowances are established by the retail operation division of the ASO with the assistance of each appropriate ACC/TYCOM for DLRs and FLRs (1RD COG) authorized for stock at each operating site and are considered as part of the activity’s OSI. Between periodic revisions of the allowance authorization document, changes to the fried allowance quantity, based on usage demand, may be requested by the item manager, ACC/ TYCOM, or the operating site. ALLOWANCE CHANGE REQUEST-FIXED The allowance change request-fried (ACR-F) is a means for the fleet to recommend a revision to the authorized fixed allowance levels. An ACR-F is submitted when the current allowance quantity does not appear to be sufficient to support the activity’s present and continuing mission. Fully justified ACR-FS are submitted on NAVSUP Form 1375 for all 7R and 1RD repairable. An ACR-F is not submitted for con- sumable expense-type items. The ACR is negotiated between the ASO and the operating activity. The ASO should process ACR-Fs within 15 working days from receipt or provide an interim message pending disposition. All unjustified requests are automatically dis- approved and returned with an explanation. ACR-F Procedures All ships (CVs/LHAs/LPHs) and marine air- craft groups (MAGs) submitting ACR-Fs to the ASO must follow procedures for quantity com- putations outlined in FASOINST 4441.15. All shore-based operating site activities submitting ACR-FS to the ASO must follow procedures for quantity computations outlined in FASOINSTs 4441.16 and 4441.20. All ACR-FS should be submitted to the ASO by message with the ACC/TYCOM as an information addressee on NAVSUP Form 1375 5-13
