i . Repair. The application of maintenance services (inspect, test,

service, adjust, align, calibrate, replace) or other maintenance actions

(welding, grinding, riveting, straightening, facing, remachining, or re-

surfacing) to restore serviceability to an item by correcting specific

damage, fault, malfunction, or failure in a part, subassembly, module

(component or assembly), end iterm, 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

p u b l i c a t i o n s . Overhaul is normally the highest degree of maintenance per-

formed by the Army. Overhaul does not normally return an item to like

new condition.

k . Rebuild. Consists of those services/actions necessary for the

restoration of unserviceable equipment to a like new condition in accord-

ance with original manufacturing standards. Rebuild is the highest

degree of materiel maintenance applied to Army equipment. The rebuild

operation includes the act of returning to zero those age measurements

(hours, miles, etc. ) considered in classifying Army equipments/components.

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 with-

out 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 list-

ingof 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 the indicated category of maintenance. If the number or comp-

lexity of the tasks 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

c o n d i t i o n 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 maint-

enance allocation chart. Subcolumns of column 4 are as follows:
