Use Of The MAC
NOTE
Approved item names are used throughout this MAC. Generic terms/ nomenclature (if any) are
expressed in parentheses and are not to be considered as oficial terminology.
This MAC assigns maintenance functions to the lowest level of maintenance, based on past experience and the
following considerations:
Skills available.
Work time required.
Tools and test equipment required and/or available.
Only the lowest level of maintenance authorized to perform a maintenance function is indicated. If the lowest
maintenance level cannot perform all tasks of any single maintenance function (e.g., test, repair), then the higher
maintenance level(s) that can accomplish additional tasks will also be indicated.
A maintenance function assigned to a maintenance level will automatically be authorized to be performed at
any higher maintenance level.
A maintenance function that cannot be performed at the assigned level of maintenance for any reason may be
evacuated to the next higher maintenance level. Higher maintenance levels will perform the maintenance functions
of lower maintenance levels when required by the commander who has the authority to direct such tasking.
The assignment of a maintenance function will not be construed as authorization to carry the related repair parts or
spares in stock. Information to requisition or otherwise secure the necessary repair parts will be as speciied in
