i. R E P A I R - The application of maintenance services (inspect, test, service, adjust,

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. Overhaul does not normally return an

item to like new condition.

k. REBUILD - Consists of those services/actions necessary for the restoration of unser-

viceable equipment to a like new condition in accordance with original manufacturing

standards. Rebuild is the highest degree of materiel maintenance applied to Army

equipment. The rebuild operation includes the act of retuning to zero those age

measurements (hours, miles, etc.) considered in classifying Army equipments/com-

ponents.

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 com-

ponents, assemblies, subassemblies modules for which maintenance is authoriz-

ed.

c. Column 3, MAINTENANCE FUNCTIONS - Column 3 lists the functions to be perform-

ed 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 authoriz-

ed to perform the function listed in column 3. This figure represents the active time re-

quired to perform that maintenance function at the indicated category of maintenance.

If the number or complexity 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 condition under typical field operating con-

d i t i o n s . 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:
