10. Overhaul. That maintenance effort (service/action) prescribed to restore an item to a
completely serviceable/operational condition as required by maintenance standards 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.
11. 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 (e.g., hours/miles) considered in classifying Army equipment/
components.
Explanation of Columns in the MAC
Column (1) – Group Number. Column (1) lists Functional Group Code (FGC) numbers, the
purpose of which is to identify maintenance significant components, assemblies,
subassemblies, and modules with the Next Higher Assembly (NHA).
Column (2) – Component/Assembly. Column (2) contains the item names of components,
assemblies, subassemblies, and modules for which maintenance is authorized.
Column (3) – Maintenance Function. Column (3) lists the functions to be performed on the item
listed in column (2). (For a detailed explanation of these functions refer to “Maintenance
Functions” outlined above).
Column (4) – Maintenance Level. Column (4) specifies each level of maintenance authorized to
perform each function listed in column (3), by indicating work time required (expressed as
manhours in whole hours or decimals) in the appropriate subcolumn. This work time figure
represents the active time required to perform that maintenance function at the indicated level of
maintenance. If the number or complexity of the tasks within the listed maintenance function
varies at different maintenance levels, appropriate work time figures are to be shown for each
level. 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 (including any necessary
disassembly/assembly time), troubleshooting/fault location time, and quality assurance time in
addition to the time required to perform the specific tasks identified for the maintenance
functions authorized in the MAC. The symbol designations for the various maintenance levels
are as follows:
C – Operator or crew maintenance
O – Unit maintenance
F – Direct support maintenance
L – Specialized repair activity (SRA)
H – General support maintenance
D – Depot maintenance
