USE OF THE MAINTENANCE ALLOCATION CHART (SECTION II).
NOTE
Approved item names are used throughout this MAC. Generic terms/nomenclatures (if any) are
expressed in parentheses and are not to be considered as official terminology.
a. This Maintenance Allocation Chart assigns maintenance functions to the lowest level of maintenance, based
on past experience and the following considerations:
(1) Skills available.
(2) Time required.
(3) Tools and test equipment required and/or available.
b. 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.
c. A maintenance function assigned to a maintenance level will automatically be authorized to be performed at
any higher maintenance level.
d. 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.
e. 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 specified
in the associated Repair Parts, and Special Tools List (RPSTL).
f. Higher level of maintenance organization commanders may authorize deviation from the assigned level of
maintenance on a case by case basis or for up to one year when the lower level maintenance organization meets the
following requirements:
(1) The lower level maintenance organization must possess the trained personnel capable of performing the
work.
(2) Inspection may be performed by the lower level when expertise is available (or provided by the higher
level).
(3) Special tools/test equipment must be available (if required) at the requesting unit or furnished by the higher
level.
B.3.
MAINTENANCE FUNCTIONS.
Maintenance functions will be limited to and defined as follows:
a. Inspect.
To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical
characteristics with established standards through examination (e.g., by sight, sound, or feel).
b. Test.
To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics
of an item and comparing those characteristics with prescribed standards.
