MAINTENANCE ALLOCATION CHART
Section 1. INTRODUCTION
This section provides a general explanation of
all maintenance and repair functions authorized at
various maintenance levels.
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
Section III (Not Applicable).
Section IV contains supplemental instructions,
explanatory notes and/or illustrations required for a
particular maintenance function.
2. Explanation of Columns in Section II
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
Functional Group, Column (2). This column
contains a brief description of the components of each
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
FDirect support maintenance
HGeneral support 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.
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
GInstall: To set up for use in an operational
environment such as an emplacement, site, or
HReplace: To replace unserviceable items with
IRepair: To restore an item to serviceable
condition. This includes, but is not limited to,
replacing, welding, riveting, and strengthening.
JOverhaul: To restore an item to a completely

KRebuild: To restore an item to a standard as
nearly as possible to original or new condition in
appearance, performance, and life expectancy.
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.
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).
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
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.
