Contingency Support Package (CSP) CSP material is stock material considered essential to mission support of deployed Marine Corps aviation units. Stock records for designated items are identified and material is stored in such a manner that removal and shipment can be done quickly. Maintenance Support Package (MSP) MSP materials are small, fast-moving, low-cost, consumable aviation repair parts. MSP material is under the custody of the supply officer and, when possible, should be located near the aircraft intermediate maintenance department (AIMD). Pre-Expended Bin (PEB) Materials in the PEB are maintenance-related, high-usage items with a unit cost of 0 or less. However, commanding officers may increase the PEB unit price limit. To qualify as a PEB item, the material must experience three demand frequencies per month. The demand frequency in this case does not necessarily mean the number of times the item is requested from supply, but to the number of times the item is required for maintenance jobs. For example, one transaction of machine screws with a unit of issue of hundred (HD) represents one issue by supply, but may represent several applications to different maintenance jobs. PEB items are expended from supply department records and placed in locations convenient to maintenance personnel on a free issue basis. The quantities of PEB items is limited to one month’s supply except for items assigned with a unit of issue (for example, gross) that may exceed the maintenance requirements for one month. SEAMART SEAMARTs are established to provide a convenient method of issuing low-cost, high-usage consumable items. Material carried in SEAMART must meet the frequency of demand and unit price limits established by the ship’s supply officer. TYCOM approval is required to establish a SEAMART. Aviation Fly-In Support Package (FISP) Materials in the FISP consist of selected aviation repair parts that accompany aircraft deploying to an amphibious operating area. The purpose of the FISP is to provide temporary organizational level supply support until such time that intermediate level facilities and materials become available. Material in the FISP is in addition to normal AVCAL allowances. The FISP is maintained as a protected stock asset by Marine Corps aircraft groups (MAGs) that provide aircraft to the maritime prepositioned ship’s marine amphibious brigade aviation combat element. Maintenance Assistance Modules (MAMs) The MAMs are replaceable assemblies required to execute approved maintenance plans that call for progressive or selected module substitution. The MAMs are considered as DLRs and are under the management control of the supply officer, but may be located in the operating and maintenance spaces under the subcustody of the operating or maintenance personnel. Test Bench Installations (TBIs) The TBIs are similar to MAMs. They are DLRs installed within a test bench and used as part of the test bench to isolate faults. The initial requirements for TBIs are identified during the AVCAL process but are not included as part of the freed allowance. The TBIs are issued to the custody of the intermediate maintenance activity (IMA) by the supply officer. Controlled Equipage Controlled equipage refers to those items of equipage that require special management control. Refer to Appendix II of NAVSUP P-485 for a list of items classified as controlled equipage. PHYSICAL INVENTORY AFLOAT Physical inventories are conducted on a scheduled or unscheduled basis to determine the accuracy of, and adjust differences between, storeroom quantities and stock records. The frequency of inventories is dependent upon the category of material involved and the degree of validity of the stock records. Preplanning and accuracy are the key factors for an effective inventory management afloat. Inventory Schedule Physical inventories afloat should be scheduled to permit accurate and timely physical counts, preliminmy and causative research, and posting to the stock records. Regular inventories of small lots are preferable to 5-15
