USE OF THE MAINTENANCE ALLOCATION CHART
B-2. GENERAL INFORMATION.
The Maintenance Allocation Chart is used to assign and authorize maintenance functions as follows.
Approved item names are used throughout this MAC. Generic terms or nomenclatures, if
used, are expressed in parentheses and are not to be considered as official terminology.
a. Maintenance Function Assignment. The Maintenance Allocation Chart assigns maintenance functions to the
lowest level of maintenance, based on past experience and the following considerations:
(1) Skills available.
(2) Work time required.
(3) Tools and test equipment required and/or available.
b. Maintenance Level Authorization. Only the lowest level of maintenance authorized to perform a
maintenance function is indicated. If the lowest maintenance level cannot perform all tasks of a single maintenance
function (e.g., test, repair), then the higher maintenance level(s) will also be indicated to accomplish additional tasks.
(1) A maintenance function assigned to a maintenance level will automatically be authorized to be performed
at any higher maintenance level.
(2) 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.
(3) 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).
(4) Normally, there will be no deviation from the assigned level of maintenance. In cases of operational
necessity, requests for a lower maintenance level may be authorized on a one-time basis. To transfer maintenance
functions to the lower level, specific authorization by the maintenance officer at the higher level of maintenance is
required. The special tools and equipment required by the lower level of maintenance will be furnished by the
maintenance level to which the function is assigned. The 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 level.
