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 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 maintenance
O -- Unit maintenance
F -- Direct support maintenance
L -- Specialized Repair Activity (SRA)
H -- General support maintenance
D -- Depot maintenance
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) -- Tools 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 the tool or test equipment.
Column (4) -- National Stock Number (NSN). The NSN of the tool or test equipment.
Column (5) -- Tool Number. The manufacturer's part number, model number, or type number.
Explanation of Columns in the Remarks
Column (1) -- Remarks Code. The code recorded in column (6) of the MAC.
Column (2) -- Remarks. This column lists information pertinent to the maintenance function being performed as
