APPENDIX B
MAINTENANCE ALLOCATION CHART
Section I. INTRODUCTION
B-1. GENERAL.
a.
This section provides a general explanation of all
maintenance and repair functions authorized at the
various maintenance levels.
b.
The Maintenance Allocation Chart (MAC) in
Section II 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 will
be consistent with the capacities and capabilities of the
designated maintenance levels.
c.
Section III lists the tools and test equipment
(both special tools and common tool sets) required for
each maintenance function as referenced from Section
II.
d.
Section IV contains supplemental instructions
and explanatory notes for a particular maintenance
function.
B-2. MAINTENANCE FUNCTIONS.
Maintenance functions will be limited to and defined as
follows:
a.
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).
b.
Test. To verify serviceability by measuring the
mechanical, pneumatic, hydraulic, 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
(includes decontaminate, when required), to preserve, to
drain, to paint, or to replenish fuel, lubricants, chemical
fluids, or gases.
d.
Adjust. To maintain or regulate, within
prescribed limits, by bringing into proper or exact
position, or by setting the operating characteristics to
specified parameters.
e.
Aline. To adjust specified variable elements of
an item to bring about optimum or desired performance.
f.
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.
g.
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 an equipment or system.
h.
Replace. To remove an unserviceable item and
Install a serviceable counterpart in its place. "Replace" is
authorized by the MAC and is shown as the third position
of the SMR code.
i.
Repair. The application of maintenance
services, Including fault location/troubleshooting,
removal/ installation, and disassembly/assembly
procedures, and maintenance actions to Identify troubles
and 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.
j.
Overhaul. That maintenance effort
(service/action) prescribed to restore an item to a
completely serviceable/operational condition as required
by maintenance standards in appropriate technical
publications (i.e., DMWR). Overhaul Is normally the
highest degree of maintenance performed by the Army.
Overhaul does not normally return an item to like new
condition.
k.
Rebuild. Consists of those services/actions
necessary for the restoration of unserviceable equipment
to a like new condition In accordance with original
manufacturing standards. Rebuild is the highest degree
of materiel maintenance applied to Army equipment.
The rebuild operation Includes the act of returning to
zero those age measurements (hours/miles, etc.)
considered in classifying Army equipment/ components.
