(1)  Source  code  indicates  the  selection  sta- tus  and  source  for  the  listed  item.  Source  codes are: Code Explanatiomn P Applies to repair parts which are stocked in or sup- plied from GSA/DSA or Army supply system, and authorized for use at indicated maintenance categories. P2 Repair parts which are procured and stocked for insurance purposes because the combat or mili- tary essentiality of the end item dictates that a minimum quantity be available in the supply sys- tem. M  Applied  to  repair  parts  which  are  not  procured  or stocked but are to be manufactured  at  indicated maintenance levels. A Applied to assemblies which are not procured or stocked as such, but are made up of two or more units, each of which carry individual stock num- bers  and  description  and  are  procured  and stocked separately and can be assembled by units at indicated maintenance categories. X Applied to parts and assemblies which are not pro- cured or stocked, the mortality of which is nor- mally below that of the applicable end item or component, and the failure of which should re- Code Explanation sult in retirement of the end item from the sup- ply system. X1  Applied  to  repair  parts  which  are  not  procured  or stocked the, requirement for which will be filled by use of the next higher assembly or component, X2 Applied to repair parts which are not stocked. The indicated  maintenance  category  requiring  such repair parts will attempt to obtain them through cannibalization; if not obtainable through can- nibalization, such repair parts will be requisi- tioned with supporting justification through nor- mal supply channels. G Applied to major assemblies that are procured with PEMA (Procurement Equipment Missiles Army) funds for initial issue only to be used as exchange assemblies at DSU and GSU level, These assem- blies will not be stocked above DS or GS level or returned to depot supply level. (2)  Maintenance  code  indicates  the  lowest category of maintenance authorized to install the listed item. The maintenance level code is: Code Explanation C   ------------------------   O p e r a t o r / c r ew (9) Recoverability   code,   indicates   whether unserviceable items should be returned for recov- ery  or  salvage.  Items  not  coded  are  expendable. Recoverability  codes  are: Code E.C*Mt&m R Applied to repair parts (assemblies and compon- ents) which are considered economically repair- able at direct and general support maintenance levels. When the maintenance capability to repair these  items  does  not  exist,  they  are  normally  dis- posed of at the GS level. When supply considera- tions dictate, some of these repair parts may be listed for automatic return to supply for depot level repair as set forth in AR 710-60. When so listed, they will be replaced by supply on an ex- change basis. S  Applied  to  repair  parts  and  assemblies  which  are economically repairable at DSU and GSU activi- ties and which normally are furnished by supply on an exchange basis. When items are determined by a GSU to be uneconomically repairable, they will be evacuated to a depot for evaluation and analysis  before T  Applied  to  high final  disposition. dollar  value  recoverable  repair B-1
