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 official terminology.
This MAC assigns maintenance functions to the lowest level of maintenance, based on past ex-
perience 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 main-
tenance level cannot perform all tasks of any single maintenance function (e.g., test, repair), then the higher main-
tenance 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 evacu-
ated 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.
