APPENDIX C MAINTENANCE ALLOCATION CHART (CONT)

APPENDIX C

Repair: The application of maintenance services or other maintenance actions to restore serviceability to an

item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module (component or

assembly), end item, or system.

Overhauls: That maintenance effort (service/action) necessary to restore an item to a completely

serviceable/operational condition as prescribed by maintenance standards (i.e., DMWR) in appropriate technical

publications. Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not

normally return an item to like new condition.-

Rebuild: Consists of those services/actions necessary for the restoration of unserviceable equipment to a

like new condition in accordance with original manufacturing standards. Rebuild is the highest degree of materiel

maintenance applied to Army equipment. The rebuild operation includes the act of returning to zero those age

measurements (hours/miles, etc) considered in classifying Army equipments/components.

Column entries: Columns used in the Maintenance allocation chart are explained below:

Column 1, Group Number: Column 1 lists group numbers, the purpose of which is to identify components,

assemblies, subassemblies, and modules with the next higher assembly.

Column 2, Component/Assembly: Column 2 contains the noun names of components, assemblies,

subassemblies, and modules for which maintenance is authorized.

Column 3, Maintenance Functions:

Column 3 lists the functions to be performed on the item listed in

Column 2.

Column 4, Maintenance Category: Column 4 specifies, by the listing of a "work time" figure in the

appropriate subcolumn(s), the lowest level of maintenance authorized to perform the function listed in Column 3. This

figure represents the active time required to perform that maintenance function at the indicated category of maintenance.

If the number of complexity of the tasks within the listed maintenance function vary at different maintenance categories,

appropriate "work time" figures will be shown for each category. The number of manhours specified by the "work time"

figure represents the average time required to restore an item (assembly, subassembly, component, module, end item or

system) to a serviceable condition under typical field operating conditions. This time includes preparation time,

troubleshooting time, and quality assurance/quality control
