d. Depot Maintenmce. 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

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 items physical, mechanical, and/or electrical characteristics with estab-
lished 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.
