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:

Field:

Operator or crew maintenance

Direct support maintenance

Sustainment:

General support maintenance

Depot maintenance

NOTE

The "L" maintenance level is not included in Column 4 of the MAC. Functions

to this level of maintenance are identified by a work time figure in the "H" column

of Column 4, and an associated reference code is used in the REMARKS

Column 6. This code is keyed to the remarks and the Specialized Repair

Activity (SRA) complete repair application is explained there.
