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
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 (tasks) outlined previously.)
Column (4) Maintenance Level. Column (4) specifies each level/class of maintenance authorized to perform each
function listed in column (3), by indicating work time required in the appropriate sub-column. This work time figure
represents the active time required to perform that maintenance task at the indicated level/class of maintenance.
If the number or complexity of the tasks within the listed maintenance task varies at different maintenance
classes, appropriate work time figures are to be shown for each class.
The work time figure represents the average time required to perform the prescribed task (assembly,
subassembly, component, module, end item, or system) on the item under typical operating conditions for that
maintenance level/class. 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 tasks authorized in the MAC. The symbol designations for the various
maintenance levels/classes and classes are as follows:
