USE OF THE MAINTENANCE ALLOCATION CHART (SECTION II.).
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.
This Maintenance Allocation Chart assigns maintenance functions to the lowest level of maintenance, based
on past experience and the following considerations:
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
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).
Normally there will be no deviation from the assigned level of maintenance. In cases of operational
necessity, at the request of a lower maintenance level and on a one-time basis, transfer of maintenance functions
to the lower level may be accomplished by specific authorization of maintenance officer of the higher level of
maintenance to which the function is assigned. The special tools, equipment, etc., required by the lower level of
maintenance to perform this function will be furnished by the maintenance level to which the function is assigned.
This transfer of a maintenance function to a lower maintenance level does not relieve the higher maintenance
level of the responsibility for the function. The higher level of maintenance will provide technical supervision and
inspection of the function being performed at the lower lever.
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 characteris-
tics of an item and comparing those characteristics with prescribed standards.
c. Service. Operations required periodically to keep an item in proper operating condition, i.e., to clean
(includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical
fluids, or gases.
