Other key letter symbols.spaced apart from and fol-
lowing the part nomenclature are for cataloging and
manufacturing purposes only and are not to be con-
sidered by the customer unless the symbol is "ARC",
or "KRC" following an avionic part. In this event,
the symbols ARC or KRC are used to flag the custom-
er that the part is to be ordered directly from ARC -
Boonton, NJ, or KRC - Olathe, KS. Refer to the fol-
lowing paragraph titled "How To Order" for instruc-
tions on ordering avionic parts directly from ARC or
KRC.
Since the factory will no longer stock these
parts, your orders for avionic equipment with an
ARC or KRS symbol will have to be forwarded to ARC
or KRC for distribution.
Therefore, orders sent
directly to ARC or KRC will result in much faster
delivery on any parts that are required.
A blank entry in the part number column appears be-
fore an unprocurable part or installation which is
also denoted in the "Units Per Assembly" column by
the useof the symbol "NP. "
GROUP ASSEMBLY PARTS LIST ARRANGE-
MENT.
This section lists all replaceable items in the air-
plane and these items are detailed on illustrations
throughout the section. The index numbers on the
illustration are keyed to each accompanying parts
list. The purpose of the index numbers is to pro-
vide complete and positive identification of the arti-
cle, but should not be used for procurement purposes.
a.
The figure and index number column of the
parts list shows the figure number once at
the beginning of the list. The figure number
is followed by a dash and the indexed number.
The remaining index numbers are preceded
by dash only.
b.
The part number column identifies the item
by part number.
c.
In the description column, relationship of
items covered is shown by the degree of
indention of each item, for example: The
radio installation (Figure 1-1) is listed in
column (1) of the description column.
The
receiver is the next lower assembly and is
therefore listed in column (2).
d.
If two or more assemblies contain a major-
ity of identical parts or the assemblies are
left or right hand, the assemblies are listed
together and the next lower assemblies or
detail parts are listed as common for both
assemblies, with the differing parts coded
for usage on the correct major assembly.
e.
Attaching parts are listed immediately be-
neath the item to be attached and preceding
any detail parts of the item. They are listed
in the same column as the item they attach
and are preceded by the caption "Attaching
Parts. " The end of the attaching parts list-
ing is followed by a separating symbol
f.
The quantity listed in the "Units Per Assem-
bly" column for attaching parts denotes the
total quantity necessary to attach only one
part. Total quantity necessary to attach
more than one part is obtained by multiply-
ing the attaching parts quantity by the number
of parts attached.
g.
Component parts of the complete airplane
which are not included in any assembly, but
which are used in conjunction with, or attach
to certain assemblies, are listed either pre-
ceding the first detail or following the last
detail of the assembly or installation, and
in the same column as the major assembly
or installation.
h.
The quantities listed in the "Units Per As-
sembly" column are the quantity used per
figure.
ACCESSORY KITS.
This manual describes the factory installation of the
equivalent field installation AK Kit and the factory
installation is considered standard and illustrated
as such.
