Chapter 3AUTHORIZED REPAIR PARTS STOCKAGEBENCH STOCK3-6. Bench stocks consist of low-cost, high-use, consumable Class II, Class III (packaged), Class IV, andClass IX (fewer components) items. Examples include common hardware, resistors, transistors, capacitors,wire, tubing, hoses, ropes, webbing, thread, welding rods, sandpaper, gasket materiel, sheet metal, seals,oils, grease, and repair kits. AR 710-2 lists the criteria an item must meet to qualify as bench stock. ALSOsor maintenance officers must approve bench stock lists semiannually.3-7. Bench stocks are not demand supported; units do not need a certain number of demands for an itemto remain on bench stock. Maintenance activities with a collocated supply support activity (SSA) maintaina 15-day supply of bench stock; activities without a collocated SSA or field maintenance unit systemmaintain a 30-day supply.PRESCRIBED LOAD LIST3-8. Units are required to stock PLLs, which consist of demand- or nondemand-supported maintenancerepair parts and initial stock repair parts for new end items. PLLs must be approved by the first generalofficer or equivalent staff level in the chain of command. PLLs allow units to maintain a supply of highuse,high-demand items available for quick repairs. Most PLL items are demand supported and must meet aset number of demands within a certain time period before ordering. AR 710-2 provides guidelines formaintaining PLLs.SHOP STOCK3-9. Shop stocks are comprised of demand-supported repair parts and consumables stocked within asupport-level maintenance activity with a support-level maintenance mission authorized by an MTOE,TDA, or joint table of allowances. These repair parts are used internally by the maintenance unit toaccomplish maintenance requests or programmed repairs. AR 710-2 covers criteria for the number ofdemands required and items authorized to fulfill shop stocks.AUTHORIZED STOCKAGE LIST3-10. The authorized stockage list (ASL) is a list of all items authorized to be stocked at specific levels tomeet the logistics needs of supported aviation customers.3-11. The supporting SSA ASL is the supply source from which aviation units may replenish theirstockage of shop stock items to authorized levels. The supporting SSA also provides a direct exchangeservice for repairable components.3-12. Demand history files are maintained to reflect the most recent 12-month period and are used tosupport decisions to stock items. At supply base SSAs, demand frequency files are maintained for everyClass II, Class III (packaged), Class IV, and Class IX (air) item issued to aviation units. Items selected forstockage make up the ASL.3-13. The ASL identifies authorized items to be stocked in the SSA to support customer demands.Although an item may qualify for inclusion in the ASL, the unit item manager may or may not add itbecause of stockage and SSA funding constraints. The Standard Army Retail Supply System (SARSS)considers an item qualified for stockage when it is demand-supported, an operational readiness float itemspecifically authorized for incorporation, an initial provisioning item, and a mission-essential or mandatorystockage item.3-14. SARSS automatically considers ASL items receiving insufficient demand during a 180-day periodfor a stockage list code change or deletion from the ASL.3-4 TC 3-04.72 15 October 2009
