Column (2) -- Component/Assembly. Column (2) contains the names of components, assemblies,
subassemblies, and modules for which maintenance is authorized.
Column (3) -- Maintenance Function. Column (3) lists the functions to be performed on the item listed in
Column (2). (For detailed explanation of these functions, refer to "Maintenance Functions" outlined
above.)
Column (4) -- Maintenance Level. Column (4) specifies each level of maintenance authorized to perform
each function listed in column (3), by indicating work time required (expressed as manhours in whole
hours or decimals) in the appropriate subcolumn. This work time figure represents the active time
required to perform that maintenance function at the indicated level of maintenance. If the number or
complexity of the tasks within the listed maintenance function varies at different maintenance 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:
C --
Operator or crew
O --
Unit maintenance
F --
Direct support maintenance
L --
Specialized repair activity (SRA)
H --
General support maintenance
D --
Depot maintenance
NOTE
The "L" maintenance level is not included in column (4) of the MAC. Functions to this
level of maintenance are identified by a work time figure in the "H" column of column (4),
and an associated reference code is used in the REMARKS column (6). This code is
keyed to the remarks and the SRA complete repair application is explained there.
Column (5) -- Tools and Equipment Reference Code. Column (5) specifies, by code, those common tool
sets (not individual tools) common Test, Measurement and Diagnostic Equipment (TMDE), and special
tools, special (TMDE), and special support equipment required to perform the designated function. Codes
are keyed to the entries in the tools and test equipment table.
Column (6) Remarks Code. When applicable, this column contains a letter code, in alphabetical order,
which is keyed to the remarks table entries.
Explanation of Columns in the Tools and Test Equipment Requirements
Column (1) -- Tool or Test Equipment Reference Code. The tool or test equipment reference code
correlates with a code used in column (5) of the MAC.
Column (2) -- Maintenance Level. The lowest level of maintenance authorized to use the tool or test
equipment.
Column (3) -- Nomenclature. Name or identification of tool or test equipment.
Column (4) -- National Stock Number (NSN). The NSN of the tool or test equipment.
