Special Tools and Test Equipment supplied from the GSA / DSA, or Army supply system  and  authorized  for  use  at  indicated maintenance categories. Repair parts, Special Tools and Test Equipment which  are  procured  and  stocked  for  insurance purposes because   the   combat   or   military essentiality  of  the  end  item  dictates  that  a minimum quantity be available in the supply system.   Repair parts, Special Tools and Test Equipment which are not procured or stocked, as such, in the Supply System but are to be manufactured at ndicated maintenance levels.   Assemblies which are not procured or stocked as such. but are made up of two or more units. such component units carry individual stock numbers  and  descriptions,  are  procured  and stocked  separately  and  can  be  assembled  to form   the   required   assembly   at   indicated maintenance categories. Parts and assemblies that are not procured or stocked  because  the  failure  rate  is  normally below that of the applicable end item or com- ponent. The failure of such part or assembly should result in retirement of the end item from the supply system.   Repair parts which are not procured or stocked. The requirement for such items will be filled by use of the next higher assembly or component. code Explanation X2   Repair parts. Special Tools and Test Equipment which are not stocked and have no foreseen mortality.  The  indicated  maintenance  category requiring  such  repair  parts  will  attempt  to obtain  the  parts  through  cannibalization  or salvage,  the  item  may  be  requisitioned  with exception data. from the end item manager. for immediate use. G   Major assemblies that are procured with PEMA funds   for initial  issue only   as exchange assemblies   at   DSU   and   GSC   level.   These assemblies will not be stocked above DS and 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 Crew / Operator (3)    Recoverability    code,    indicates    whether unserviceable   items   should   be   returned   for   recovery or   salvage.   Items   not   coded   are   non-recoverable. Recoverability   codes   are: code Explanation R Applied to repair parts. (assemblies and com- ponents)  special  tools  and  test  equipment  which are considered economically reparable at direct and general support maintenance levels. When the item is no longer economically reparable. it is normally disposed of at the GS level. When supply  considerations  dictate.  some  of  these repair parts may be listed for automatic return to supply for depot level repair as set forth in AR  710-30.  When  so  listed.  they  will  be replaced  by  supply  on  an  exchange  basis. S Repair parts, special tools. test equipment and assemblies which are economically reparable at DSU  and  GSU  activtities  and  which  normally are furnished by supply on an exchange basis. When items are determined by a GSU to be uneconomically   reparable.   they   will   be evacuated to a depot for evaluation and analysis before final disposition. T   High dollar value recoverable repair parts. special tools and test equipment which are subject to special handling and are issued on an exchange basis. Such items will be repaired or overhauled at depot maintenance activities only. No repair may be accomplished at lower levels. U Repair parts, special tools 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.
