MAINTENANCE ALLOCATION CHART (MAC) INTRODUCTION
The Army Maintenance System MAC
This introduction provides a general explanation of all maintenance and repair functions authorized at
various maintenance levels under the standard Army Maintenance System concept.
The MAC (WP 0062 00, Table 1, immediately following the introduction) designates overall authority and
responsibility for the performance of maintenance functions on the ASLMS. The application of the
maintenance functions to the ASLMS shall be consistent with the capacities and capabilities of the
designated maintenance levels, which are shown on the MAC in column (4) as:
Unit includes two sub columns, C (operator/crew) and O (unit) maintenance.
Direct Support includes an F sub column.
General Support includes an H sub column.
Depot includes a D sub column.
The tools and test equipment requirements (WP 0062 00, Table 2, immediately following the MAC) list the
tools and test equipment (both special tools and common tool sets) required for each maintenance
function as referenced from the MAC.
The remarks (WP 0062 00, Table 3, immediately following the tools and test equipment requirements)
contain supplemental instructions and explanatory notes for a particular maintenance function.
Maintenance functions are limited to and defined as follows:
1. Inspect: To determine the serviceability of an item by comparing its physical, mechanical, and/or
electrical characteristics with established standards through examination (e.g., by sight, sound, or
feel). This includes scheduled inspections.
2. Test: To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical
characteristics of an item and comparing those characteristics with prescribed standards on a
scheduled basis, i.e., load testing of lift devices and hydrostatic testing of pressure hoses.
3. Service: Operations required periodically to keep an item in proper operating condition; e.g., to clean
(includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel,
4. Adjust: To maintain or regulate, within prescribed limits, by bringing into proper position, or by setting
the operating characteristics to specific parameters.
