B-2. USE OF THE MAC.
a. The Maintenance Allocation Chart assigns maintenance functions to the lowest cate-
gory 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. Only the lowest category of maintenance authorized to perform a maintenance func-
tion is indicated. If the lowest maintenance category 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 category will automatically be
authorized to be performed at any higher maintenance category.
d. A maintenance function that cannot be performed at the assigned category of mainte-
nance for any reason may be evacuated to the next higher maintenance category.
Higher maintenance categories will perform the maintenance functions of lower main-
tenance categories when required or directed by the commander that has the author-
ity 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 other-
wise secure the necessary repair parts will be as specified in the associated Repair
Parts and Special Tools List (RPSTL).
f. Normally there will be no deviation from the assigned level of maintenance. In cases
of operational necessity, maintenance functions assigned to a maintenance level
may, on a one time basis and at the request of the lower maintenance-level, be spe-
cifically authorized by the maintenance officer of the 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 responsi-
bility for the function. The higher level of maintenance will provide technical supervi-
sion and inspection of the function being performed at the lower level.
g. Changes to the Maintenance Allocation Chart will be based on continuing evaluation
and analysis by responsible technical personnel and on reports received from field ac-
tivities.
