d.
Description Column. This column contains the description of all items appearing on the MPL. The
indentation headed "1" through "7" consists of the approved item name, as found in the Federal Item
Identification Guide for Supply Catalog Handbook H6-1, or is in accordance with the contractor's
drawing title. The description contains modifiers necessary to identify the particular item. Additional
information following the item description may include the following: a list of alternate part numbers
to give stock ordering information; exceptions to the Usable On Code for the item; and references to
preceding and subsequent figures concerning assemblies and subassemblies. This data is considered
an integral part of the item description assuring the correctness of repair maintenance procedures.
e.
Attaching Parts. Items used to attach parts or assemblies to each other are listed immediately after the
part. The attaching parts have the same indentation code as the parts attached. The code (AP) appears
on the same line with and immediately following the attaching part item.
f.
Units Per Assembly. This column contains the number of units required per assembly and/or
subassembly. If more than one assembly is required, the total number of assemblies is listed. When
an assembly or subassembly is listed more than once, the total number of units per assembly or
subassembly appears the first time and REF for subsequent listings.
g.
Usable on Code Column. This column shows the Usable On Codes for systems, assemblies, and parts
indicating specific usability by part number. Usable on code explanations are located at the bottom of
the applicable page. The codes A, B, C, etc., when shown within a group, relate the part back to the
same coded part within the next higher assembly. When this column is left bank, an assembly or part
is common to all part number variation of the next higher assembly.
h.
Source, Maintenance, and Recoverability (SMR) Codes. This manual contains Joint Military Services
Uniform SMR codes. Detailed coding criteria may be obtained from T.O. 00-25-195.

NUMERICAL INDEX
The Numerical Index (Chapter 7, Section III) is compiled in accordance with the numerical part number filing system
described in paragraph a.
a.
Part Number Column. This column contains all the part numbers that appear in the Maintenance Parts
List and part numbers that have been assigned to detail parts assembled into the end article. The order
of procedure establishing the precedence in which the part numbers are listed is explained below. The
order of precedence in the first position of each part number is Letters A through Z, Numerals 0 through
9.
NOTE
Alphabetical O's are considered as numerical zeroes in all positions in each part number.
The order of precedence in the second and succeeding positions in each part number is as follows:
(1)
Space (blank column).
(2)
Diagonal (/).
(3)
Period (.).
(4)
Dash (-).
(5)
Letters A through Z.
(6)
Numerals 0 through 9.
The following is a sample of part numbers arranged in alphabetical-numerical sequence used in the
Numerical Index.
