Column (4) - Maintenance Level. Column (4) specifies each level of maintenance authorized to perform each function listed in column (3), by indicating work time

maintenance function at the indicated level of maintenance. If the number or complexity of the tasks within the listed maintenance function varies at different main-
tenance 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:
