agjust, align, calibrate, replace) or other maintenance actions (welding,

grinding, riveting, straightening, facing, remachining, or resurfacing) to

restore serviceability to an item by correcting specific damage, fault,

malfunction, or failure in a part, subassembly, module (component or assembly),

end item, or system.

j . Overhaul. That maintenance effort (service/action) necessary to restore

an item to a completely serviceable/operational condition as prescribed by

maintenance standards (i.e., DMWR) in appropriate technical publications.

Overhaul is normally the highest degree of maintenance performed by the Army.

B-3. Column Entries

a. Column 1, Group Number. Column 1 lists group numbers, the purpose of

which is to identify components, assemblies, subassemblies, and modules with

the next higher assembly.

b . Column 2, Component/Assembly. Column 2 contains the noun names of

components, assemblies, subassemblies, and modules for which maintenance is

authorized.

c. Column 3, Maintenance Functions. Column 3 lists the functions to be

performed on the item listed in column 2. When items are listed without

maintenance functions, it is solely for purpose of having the group numbers in

the MAC and RPSTL coincide.

d. Column 4, Maintenance Category. Column 4 specifies, by the listing of

a "work time" figure in the appropriate subcolumn(s), the lowest level of

maintenance authorized to perform the function listed in column 3. This figure

represents the active time required to perform that maintenance function at

t h e indicated category of maintenance. If the number or complexity of the

task within the listed maintenance function vary at different maintenance

categories, appropriate "work time" figures will be shown for each category.

The number of task-hours specified by 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, troubleshooting

time, and quality assurance/quality control time in addition to the time

required to perform the specific tasks identified for the maintenance functions

authorized in the maintenance allocation chart. Subcolumns of column 4 are

as follows:
