Recoverability codes are: Code Explanation R Applied to repair parts (assemblies and components ) which are considered economically reparable at direct and general support maintenance levels. When the maintenance capability to repair these items does not exist, they are normally disposed of at the GS level. When supply considerations dic- tate, some of these spare 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 and assemblies which are economically reparable at DSU and GSU activities and which normally are furnished by supply on an ex- change basis. When items are deter- mined by a GSU to be uneconomically reparable, they will be evacuated to a depot for evaluation and analysis be- fore final disposition. T High dollar value recoverable repair parts which are subject to special handling and are issued on an exchange basis.
