Code Explanation R-Repair parts (assemblies and components), special tools and test equipment which are considered economically reparable at direct and general sup- port maintenance levels. When the item is no longer economically reparable, it is normally disposed of at the GS level. When supply con- siderations dictate, some of these repair parts may be listed for automatic return to supply for depot level repair as set forth in AR 710-50. When so listed, they will be replaced by supply on an exchange basis. S-Repair parts, special tools and test equipment, and assemblies which are economically reparable at DS and GS activities and which normally are furnished by supply on an exchange basis. When items are determined by a GSU to be uneconomic- ally reparable, they will be evacuated to a depot for evaluation and analysis before final disposi- tion. T-High dollar value recoverable repair parts, special tools and test equipment which are subject to special handling and are issued on an exchange bask Such items will be repaired or overhauled at depot maintenance activities only. No repair may be accomplished at lower levels. U-Repair parts, special took and test equipment specifically selected for salvage by reclamation units because of precious metal content, critical materials, high dollar value, or reusable casings or castings. b. Federal Stock Number. Indicates the Federal stock number assigned to the item and will be used for requisitioning purposes. c. Description. Indicates the Federal item name and a minimum description required to identify the item, The last line indicates the reference number followed by the applicable Federal Sup- ply Code for Manufacturer (FSCM) in paren- theses. The FSCM is used as an element in item identification to designate manufacturer or dis- tributor or Government Agency, etc., and is iden- tified in SB 708-42. d. Unit of Measure (U/M). Indicates the stand- ard or basic quantity by which the listed item is used in performing the actual maintenance function. This measure is expressed by a two- character alphabetical abbreviation, e.g., ea, in, pr, etc., and is the basis used to indicate quantities and allowances in subsequent columns. When the unit of measure differs from the unit of issue, the lowest unit of issue that will satisfy the required units of measure will be requisitioned. e. Quantity Incorporated in Unit. Indicates the quantity of the item used in the breakout shown in the illustration figure, which is prepared for a functional group, subfunctional group, or an as- sembly. A “V” appearing in this column in lieu of a quantity indicates that no specific quantity is applicable, e.g., shims, spacers, etc. f. 30-Day DS/GS Maintenance Allowances. Note. Allowances in GS Column are for GS Maintenance only. (1) The allowance columns are divided into three subcolumns. Indicated in each subcolumn, opposite the first appearance of each item in each category of maintenance, is the total quantity of items authorized for the number of equipments supported. Subsequent appearances of the same item will have the letters “REF” in the applicable allowance columns, indicating total allowance quantities will be shown with the first appearance of the item when shown as a supply item. Items authorized for use as required but not for initial stockage are identified with an asterisk in the al- lowance column. (2) The quantitative allowances for DS/GS levels of maintenance will represent initial stock- age for a 30-day period for the number of equip- ments supported. (3) Determination of the total quantity of parts required for maintenance of more than 100 of these equipments can be accomplished by con- verting the equipment quantity to a decimal fac- tor by placing a decimal point before the next to last digit of the number to indicate hundredths and multiplying the decimal factor by the parts quantity authorized in the 51-100 allowance col- umn. Example. authorized allowance for 51-100 equipments is 40; for 150 equipments multiply 40 by 1.50 indicating 60 parts required. g. 1-Year Allowances Per 100 Equipments/ Contingency Planning Purposes. This column in- dicates opposite the first appearance of each item the total quantity required for distribution and contingency planning purposes. Subsequent ap- pearances of the same item will have the letters “REF” in this column when shown as a supply item. The range of items indicates total quantities of all authorized items required to provide for adequate support of 100 equipments for one year. h. Depot Maintenance Allowance Per 100 Equip- ments. This column indicates opposite the first appearance of each item the total quantity au- thorized for depot maintenance of 100 equipments. Subsequent appearances of the same item will have the letters “REF” in this column when shown as a supply item. Items authorized for use but not for initial stockage are identified with an asterisk in the allowance column. i. Illustration. This column is divided as follows: (1) Figure Number. Indicates the figure number of the illustration on which the item is shown. 3
