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) TooIs 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), than 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 main-
tenance 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 deter-
mine 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 in-
cluded 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.
