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
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. C o l u m n 4 specifies, by the listing
o f a "work time" figure in the appropriate subcolumn(s), the lowest level of
m a i n t e n a n c e 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 com-
p l e x i t y of the tasks within the listed maintenance function vary at
d i f f e r e n t 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. T h i s time includes
p r e p a r a t i o n time, troubleshooting time, and quality assurance/quality
