Section I Introduction
1. General: This Maintenance Allocation Chart (MAC) designates responsibility for performance of maintenance functions
to specific maintenance categories.
2. Maintenance Functions: Maintenance functions will be limited to and defined as follows:
a.
Inspect: To determine the serviceability of an item and detect incipient failure by comparing its physical,
mechanical and/or electrical characteristics with established standards through examination.
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.
c.
Service: Operations required periodically to keep an item In proper operating condition, i.e., to clean
(decontaminate), to preserve, to drain, to paint or to replenish fuel, lubricants, hydraulic fluids, or
compressed air supplies.
d.
Adjust: To maintain, within prescribed limits, by bringing into proper or exact position, or by setting the
operating characteristics to specified parameters.
e.
Install: The act of emplacing, seating or fixing Into position an item, part, or module (component or
assembly) in a manner to allow the proper functioning of an equipment or system.
f.
Replace: The act of substituting a serviceable like-type part, subassembly, or module (component or
subassembly) for an unserviceable counterpart.
g.
Repair: The application of maintenance services (inspect, test, service, adjust, align, calibrate, or replace)
or other maintenance actions (welding, grinding, riveting, straightening, facing, re-machining, or
resurfacing) to restore serviceability to an item by correcting specific damage, fault, malfunction, or failure
in a part, subassembly, module (component or assembly) end item or system.
h.
Overhaul: That maintenance effort (service/action) necessary to restore an item to a completely
serviceable/operational condition as prescribed by maintenance standards (i.e. DMWR) In appropriate
technical publications. Overhaul Is normally the highest degree of maintenance performed by the Army.
Overhaul does not normally return an item to like new condition.
3. Column Entries: Columns used In the MAC and entries for these columns are explained below:
a.
Column 1: Group Number: Column 1 lists group numbers, the purpose of which Is to Identify components,
