Explanation of Columns in the MAC--Continued

Column (2)--Component/Assembly. Column (2) contains the item 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 a 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 man-

hours 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 functions are as

follows:

Field:

C--Operator or crew maintenance

O--Unit maintenance

F-- Direction support maintenance

Sustainment:

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.

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.
