3. EXPLANATION OF COLUMNS IN THE MAC - Continued
NOTE
When a complete replace or repair task performed at higher level maintenance
includes lower level maintenance tasks (equipment condition/follow-on tasks),
the lower level work time figures in the MAC must be added to the higher level
work time shown in the MAC to determine the total to accomplish that
maintenance function.
d.
Column (4) - Maintenance Level. Column 4 specified each level of maintenance authorized to
perform each function listed in Column 3, by indicating a 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 the maintenance function at the indicated level of
maintenance. If the number or complexity of the tasks within the listed maintenance function
vary 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/assembly time), troubleshooting/fault location time, and quality assurance time in
addition to the time 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)5
H-
General Support Maintenance
D-
Depot Maintenance
e. Column (5) - Tools and Test Equipment Reference Code. Column 5 specifies, by code those
common tool sets (not individual tools), common TMDE, and special tools, special TMDE, and
special support equipment required to perform the designated function. Codes are keyed to
Tools and Test Equipment in Section III.
f.
Column (6) - Remarks. When applicable, this column contains a letter code, in alphabetical
order, which is keyed to the remarks contained in Section IV.
5.
This maintenance level is not included in Section II, column (4) of the MAC. Functions to this level of maintenance are
identified by a work-time figure in the "H" column of Section II, column (4), and an associated reference code is used in
the "Remarks" column (6). This code is keyed to Section IV, Remarks, and the SRA complete repair application is explained
there.
