Column (4) - Maintenance Level. Column 4 specifies each level of maintenance authorized to
perform each function listed in Column 3, by indicating a work time required (expressed as man-hours in whole
hours or decimals) in the appropriate subcolumn. This work-time figure represents the active time required to per-
form that maintenance function at the indicated level of maintenance. If the number or complexity of the tasks
within the listed maintenance function vary at different maintenance levels, appropriate work-time figures are
shown for each level. The work-time figure represents the average time required to restore an item (assembly, sub-
assembly, component, module, end item, or system) to a serviceable condition under typical field operating condi-
tions. This time includes preparation time (equipment condition/follow-on tasks) (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:
