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/Marine Corps Maintenance System concept.
The MAC (immediately following the introduction) designates overall authority and responsibility for the
performance of maintenance functions on the identified end item or component. The application of the
maintenance functions to the end item or component 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 subcolumns, C (operator/crew) and O (unit) maintenance.
Direct Support – includes an F subcolumn.
General Support – includes an H subcolumn.
Depot – includes a D subcolumn.
The tools and test equipment requirements (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 (immediately following the tools and test equipment requirements) contain supplemental
instructions and explanatory notes for a particular maintenance function.
Maintenance Functions
Maintenance functions will be 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.
2. Test - To verify serviceability of an item by comparing its physical, mechanical, and/or electrical
characteristics with prescribed standards.
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, lubricants,
hydraulic fluids, or gases.
4. Adjust - To maintain or regulate, within prescribed limits, by bringing into proper position, or by setting
the operating characteristics to specified parameters.
5. Align - To adjust specified variable elements of an item to bring out optimum or desired performance.
6. Calibrate - To determine and cause corrections to be made or to be adjusted on instruments or test,
measuring, and diagnostic equipment used in precision measurement. Consists of comparisons 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 being compared.
7. Remove/Install - To remove and install the same item when required to perform service or other
maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair
part, or module (component or assembly) in a manner to allow the proper functioning of equipment or
system.
