APPENDIX II
MAINTENANCE ALLOCATION CHART
Section 1. INTRODUCTION
1. General
a.
This section provides a general explanation of
all maintenance and repair functions authorized at
various maintenance levels.
b.
Section II designates overall responsibility for
the performance of maintenance functions on the
identified end item or component. The implementation
of the maintenance functions upon the end item or
component will be consistent with the assigned
maintenance functions.
c.
Section III (Not Applicable).
d.
Section IV contains supplemental instructions,
explanatory notes and/or illustrations required for a
particular maintenance function.
2. Explanation of Columns in Section II
a.
Group Number, Column (1). The functional
group is a numerical group set up on a functional basis.
The applicable functional grouping indexes (obtained
from TB 750-93-1, Functional Grouping Codes) are
listed on the MAC in the appropriate numerical
sequence. These indexes are normally set up in
accordance with their function and proximity to each
other.
b.
Functional Group, Column (2). This column
contains a brief description of the components of each
functional group.
c.
Maintenance Functions, Column (3). This
column lists the various maintenance functions (A
through K) and indicates the lowest maintenance
category authorized to perform these functions. The
symbol designations for the various maintenance
categories are as follows:
COperator or crew
OOrganizational maintenance
FDirect support maintenance
HGeneral support maintenance
DDepot maintenance
The maintenance functions are defined as follows:
AInspect: To determine serveability of an item by
comparing its physical, mechanical, and electrical
characteristics with established standards.
B Test: To verify serviceability and to detect electrical
or mechanical failure by use of test equipment.
C Service: To clean, to preserve, to charge, to paint,
and to add fuel, lubricants, cooling agents, and air.
DAdjust: To rectify to the extent necessary to
bring into proper operating range.
EAline: To adjust specified variable elements of
an item to being to optimum performance.
F Calibrate: To determine the corrections to be
made in the readings of instruments or test
equipment used in precise measurement.
Consists
of
the
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 with the certified
standard.
GInstall: To set up for use in an operational
environment such as an emplacement, site, or
vehicle.
HReplace: To replace unserviceable items with
serviceable
assemblies,
subassemblies,
or
parts.
IRepair: To restore an item to serviceable
condition. This includes, but is not limited to,
inspection,
cleaning,
preserving,
adjusting,
replacing, welding, riveting, and strengthening.
JOverhaul: To restore an item to a completely
serviceable
condition
as
prescribed
by
maintenance serviceability standards using the
Inspect and Repair Only as Necessary (IROAN)
technique.
KRebuild: To restore an item to a standard as
nearly as possible to original or new condition in
appearance, performance, and life expectancy.
This
is
accomplished
through
complete
disassembly of the item, inspection of all parts
or components, repair or replacement of worn or
unserviceable elements (items) using original
manufacturing tolerances and specifications,
and subsequent reassembly of the item.
d.
Tools and Equipment, Column (4). This column
is provided for referencing by code the special tools and
test equipment (Sec. III) required to perform the
maintenance functions (Sec. II).
e.
Remarks, Column (5). This column is provided
for referencing by code the remarks (Sec. III) pertinent
to the maintenance functions.
3. Explanation of Columns in Section IV
a.
Reference Code. This column consists of two
letters separated by a dash, both of which are
references to Section II. The first letter references
Column (5) and the second letter references a
maintenance function, Column (3), A through K.
b.
Remarks.
This
column
lists
information
pertinent to the maintenance function being performed,
as indicated on the MAC, Section II.
