AVIATION CONSOLIDATED ALLOWANCE LIST The aviation consolidated allowance list (AVCAL) is developed and published by the NAVICP-Phil. The AVCAL lists the range and depth of aviation material that is authorized to be stocked by a ship to support maintenance and operations of embarked aircraft. The AVCAL incorporates consumer level requirements that are in agreement with approved maintenance plans and are tailored to each using activity. The fixed allowance requirements included within the AVCAL are negotiated with the NAVICP, cognizant TYCOM, and user activity at AVCAL quality review conferences (AQRCs). The result of the AQRCs will ensure propositioning of retail stocks at the operating site to provide adequate material support. The intent of the AVCAL is to provide optimum ship's effectiveness and aircraft operational readiness in a combat environment. NOTE: Ashore activities use a shore-based consolidated allowance list (SHORCAL) in place of the AVCAL. Both procedures are basically the same. The SHORCAL is ordinarily associated with consumer level support for aviation depot and field level repairable. However, the SHORCAL includes both consumable and repairable allowances when initially established for an operating site. Subsequent SHORCAL requirements for consumable items must be for new aircraft or a weapons system. TERMS AND DEFINITIONS The following paragraphs discuss some of the terms peculiar to the AVCAL l Allowance Change Request-Fixed (ACR-F) is the document submitted to NAVICP-Phil by the operating site requesting a change in quantity to a fixed allowance. ACR-Fs are submitted on NAVSUP Form 1375. . Allowance Requirements Register (ARR) is an allowance document containing potential range and depth of aviation material to support maintenance requirements anticipated during a 90-day period. It is based on estimated reliability factors or failure rates derived from actual system-wide usage. . Beyond Capability of Maintenance (BCM) is an action taken by IMAs when repair is not authorized at that level or when an activity is not capable of doing the repair because of a lack of equipment, parts, facilities, technical skills, technical data, and so forth. Refer to OPNAVINST 4790.2 for a list of BCM codes. l Deckload includes total aircraft and equipment types and numbers embarked on a particular ship. . Endurance Period is the length of time, expressed in months, a consumer level inventory is required to support an operating site's mission without resupply. . Fixed Allowance is an authorized level of repairable regarded as the maximum level of inventory to be maintained. . Maintenance Support Packages (MSPs) contain consumable, low-cube, nonhazardous maintenance items that are maintained in MSP cabinets. Under the fleet aviation logistics support center (FALSC), shipboard aviation stocks are off-loaded to designated naval air stations for inventory management purposes. MSP material is stored in designated cabinets in mockup staging areas. The MSP cabinets will be positioned on the ship at the time of re-AVCAL. l Operational Support Inventory (OSI) is the quantity of prepositioned material required to support the planned aircraft program and maintenance mission of an operating site. The OSI is composed of "fixed allowance" for DLR and FLR as well as "fixed" operating level for consumables. . Order and Shipping Time (OST) is the interval between the time a stock point processes a stock replenishment requisition to a supplier and receipt of an NAVICP (supplier) in-stock item. The OST is currently fixed at 17 days. . Supplemental Aviation Spares Support (SASS) is commonly retimed to as a pack-up kit that is required to support detached aircraft operations. The SASS is composed of DLR and FLR items. Authorized SASS require \ments are considered additive to an operating site's fixed allowance. . The Weapons System Planning Document (WSPD) is a policy and planning document produced by NAVAIR. The WSPD provides the guidance necessary for the acquisition and logistics support of naval aircraft. The WSPD provides the number of aircraft at each site, levels of maintenance capability, pack-up requirements, carrier schedules, rotational aircraft assignments, and approved flying hours. OSI REQUIREMENTS DETERMINATION The community approach is used in determining the OSI requirements. This process is used for both repairable and consumable items as described in the following paragraphs. Consumable Items In a community approach, consumable requirements are determined by using the Ship's AVCAL Asset Demand Tape (SAVAST) from carriers that are supporting the same aircraft and equipment, including those undergoing re-AVCAL. This method is designed to maximize the range for irregular demand patterns. This method also minimizes the establishment of new items for the purpose of recording its number of demands. The community SAVAST process includes taking data from four recently deployed aircraft carriers and data characteristics off the SAVAST undergoing re-AVCAL and creating, a combined SAVAST. Items on the SAVAST that have positive average monthly demand (AMD) and are not applicable in NAVICP-Phil tiles are included in the preliminary products. A new technique has been implemented to determine the repairable fixed allowances for carriers/amphibious ships. Essential] y, the collective 3-M experience gained from recently deployed aircraft carriers is used as the basis to determine the baseline fixed allowance. In this manner the usage experience during deployment of all aircraft carriers is considered rather than that of a single carrier. Baseline fixed allowance is considered the standard aircraft carrier allowance and is incorporated into the preliminary AVCAL. Changes to the baseline fixed allowance formulate the basis of negotiations at the AQRC. Initial Outfitting The ARR columnar quantity is selected for AVCAL inclusion for weapons systems not previously supported. Applicable Constraints The attrition allowance quantities for items with identical ARR application on the previous and current AVCAL and reflect zero usage will be reduced to one. Protected aircraft and weapons systems are not subject to constraints. When requested by the type commander, additional exceptions to the constraint program maybe applied. Preliminary Requirement Stock levels developed from the mechanized requirements process are used as the point of departure in AVCAL negotiations. The established allowance or revisions during Readiness Improvement Program (RIP) reviews will be included into the preliminary AVCAL and be considered as NAVICP-Phil recommended quantities. Readiness Improvement Program (RIP) During the RIP, specifically selected aircraft/ systems are reviewed to identify logistics problems. As a result of the RIP, some allowances at an operating site may or may not get adjusted. Increases in depth and additions to the range to the ship's allowance are implemented during the re-AVCAL. Preliminary AVCAL Aids The Naval Inventory Control Point-Philadelphia (NAVICP-Phil) forwards the preliminary AVCAL review aids to the applicable ship and cognizant TYCOM 45 days before the scheduled conference date. AVCAL Quality Review Conference (AQRC) The NAVICP-Phil convenes the conference to negotiate the allowance requirement of the operating site. The information in the site's maintenance data collection system is the primary element in negotiations of repairable items. The information includes the number of items processed as BCM, items repaired, and the TAT of repairs. The NAVICP-PMI adjusts the preliminary requirement levels to reflect the negotiated allowance. Authorized changes will be incorporated in the final AVCAL products that are forwarded to the operating site. NOTE: The ACR-F is used to request an increase or decrease in allowance after the re-AVCAL. Miscellaneous Requirements Other OSI requirements include the industrial support package (ISP) and the supplemental aviation spares support (SASS). The ISP is designed to provide an 8-month range and depth support for an aircraft carrier's LRCA and is currently incorporated in the community SAVAST. The SASS is supplemental and not additive to the operating site's AVCAL quantity. These requirements are based on several factors, as follows: The level of repair The number and type(s) of aircraft to be supported Predicted removals The flying hours expected over an endurance period |
