TM 5-4320-275-13&P
d. Depot Maintenance. Depot level functions are authorized as indicated by entries in the Depot (D) Maintenance level
column (4) in the MAC.
B-2. USE OF THE MAINTENANCE ALLOCATION CHART, SECTION II
a. The MAC assigns maintenance functions based on the following considerations:
(1) Skills available.
(2) Work time required.
(3) Tools and test equipment required and/or available.
b. If a lower level of maintenance identified in column (4) of the MAC cannot perform all tasks of a single
maintenance function (e.g., test, repair), then the higher level that can perform other tasks of that function is also
indicated.
c. Higher maintenance levels are automatically authorized to perform maintenance functions assigned to a lower
maintenance level.
d. Higher maintenance levels will perform the maintenance functions of lower maintenance levels when required or
directed by the Commander who has authority to direct such tasking.
e. Assignment of a maintenance function in the MAC does not carry automatic authorization to carry the related
spare or repair parts in stock. Information to requisition or secure parts will be as specified in the associated RPSTL.
f. Normally, there will be no deviation from the assigned level of maintenance. However, in cases of operational
necessity, maintenance functions assigned a higher level may, at the request of the lower level, be assigned to the lower
level on a one-time basis, if specifically authorized by the maintenance officer of the higher level to which the function is
assigned. In such a case, the special tools, equipment, etc., required by the lower level to perform this function will be
furnished by the higher level assigned the function. Also, transfer of a function to a lower level does not relieve the
higher level of responsibility for the function, so the higher level will provide technical supervision and inspection of the
function being performed at the lower level.
B-3. MAINTENANCE FUNCTIONS
Maintenance functions will be limited to and defined as follows:
a. Inspect. Two levels of inspect are covered in the MAC.
(1) When prescribed at the C or O element of Unit Maintenance level, inspect means to determine serviceability
by comparing an item's physical, mechanical, and/or electrical characteristics with established standards through
examination (i.e., by sight, sound, or feel). These inspections are included in preventive maintenance (PM) checks and
services, such as PMCS, PMD.
(2) When prescribed at the Intermediate (F) or Depot (D) maintenance level, inspect refers to an initial
inspection which is conducted prior to scheduling any repair on repairable items evacuated to this level. This inspection
is made to determine whether an item qualifies for repair or discard.
b. Test. To verify serviceability and detect incipient failure by measuring the mechanical or electrical characteristics
of an item and comparing those characteristics with prescribed standards.
