be limited to tasks requiring cleaning and the re-
placement of seals, fittings and items of common
hardware. Unserviceable reparable modules/ compo-
nents and end items which are beyond the capability of
AVIM to repair will be evacuated to Depot Mainte-
nance. This level will perform special inspections
which exceed AVUM capability. Provides quick re-
sponse maintenance support, on-the-job training, and
technical assistance through the use of mobile mainte-
nance contract teams. Maintains authorized opera-
tional readiness float. Provides collections and classi-
fication services for serviceable/unserviceable material.
Operates a cannibaliztion activity in accordance with
AR 750-50. (The aircraft maintenance company within
the maintenance battalion of a division will perform
AVIM functions consistent with air mobility require-
ments and conservation of personnel and equipment
resources. Additional intermediate maintenance sup-
port will be provided by the supporting non-divisional
B-2. USE OF THE MAlNTENANCE ALLOCATION
a. The MAC assigns maintenance functions to the
lowest level of maintenance based on past experience
and the following consideration
(1) Skills available.
(2) Time required.
(3) Tools and test
equipment required and/or
b. Only the lowest level of maintenance authorized
to perform a maintenance function is indicated. If the
lowest level of maintenance cannot perform all tasks of
any single maintenance function (e.g., test, repair ),
then the higher maintenance level(s) that can accom-
plish 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
organization. Higher maintenance levels will perform
the maintenance functions of lower maintenance levels
when required or directed by the appropriate com-
e. The assignment of a maintenance function will not
be construed as authorization to carry the associated
repair parts in stock. Authority to requisition, stock, or
otherwise secure necessary repair parts will be as
specified in the repair parts and special tools list
f. Normally there will be no deviation from the
assigned level of maintenance. In cases of operational
necessity, maintenance functions assigned to a main-
tenance level may, on a one-time basis and at the
request of the lower maintenance level, be specifically
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 func-
tion is assigned. This transfer of a maintenance func-
tion to a lower maintenance level does not relieve the
higher maintenance level of the responsibility of the
function. The higher level of maintenance will provide
technical supervision and inspection of the function
being performed at the lower level.
g. Organizational through depot maintenance of the
US Army Electronics Command equipment will be
performed by designated US Army Electronics Com-
h. Changes to the MAC will be based on continuing
evaluation and analysis by responsible technical per-
sonnel and on reports received from field activities.
a. Inspect. To determine serviceability of an item by
comparing its physical, mechanical and electrical
characteristics with established standards.
b. Test. To verify serviceability and detect incipient
failure by measuring the mechanical or electrical
characteristics of an item and comparing those charac-
teristics with prescribed standards.
c. Service. To clean, to preserve, to charge, and to
add fuel, lubricants, cooling agents and air.
d. Adjust. To rectify to the extent necessary to bring
into proper operating range.
e. Align. To adjust specified variable elements of an
item to bring to optimum performance.
f. Calibrate. To determine the corrections to be made
in the readings of instruments or test equipment used
in precise measurement. Consists of the comparison of
two instruments, one of which is a certified standard of
known accuracy, to detect and adjust any discrepancy
in the accuracy of the instrument or test equipment
being compared with the certified standard.
g. Install. To set up for use in an operational envi-
ronment such as an emplacement, site or vehicle.
