Explanation
R-Repair parts (assemblies and components), special
tools and test equipment which are considered
economically reparable at direct and general sup-
port maintenance levels. When the item is no
longer economically reparable, it is normally
disposed of at the GS level. When supply con-
siderations dictate, some of these repair parts
may be listed for automatic return to supply
for depot level repair as set forth in AR 710-50.
When so listed, they will be replaced by supply
on an exchange basis.
S-Repair parts, special tools and test equipment, and
assemblies which are economically reparable at
DS and GS activities and which normally are
furnished by supply on an exchange basis. When
items are determined by a GSU to be uneconomic-
ally reparable, they will be evacuated to a depot
for evaluation and analysis before final disposi-
tion.
T-High dollar value recoverable repair parts, special
tools and test equipment which are subject to
special handling and are issued on an exchange
bask Such items will be repaired or overhauled
at depot maintenance activities only. No repair
may be accomplished at lower levels.
U-Repair parts,
special took and test equipment
specifically selected for salvage by reclamation
units because of precious metal content, critical
materials, high dollar value, or reusable casings
or castings.
b. Federal Stock Number.
Indicates the Federal
stock number assigned to the item and will be
used for requisitioning purposes.
c. Description.
Indicates the Federal item name
and a minimum description required to identify
the item, The last line indicates the reference
number followed by the applicable Federal Sup-
ply Code for Manufacturer (FSCM) in paren-
theses. The FSCM is used as an element in item
identification to designate manufacturer or dis-
tributor or Government Agency, etc., and is iden-
tified in SB 708-42.
d. Unit of Measure (U/M).
Indicates the stand-
ard or basic quantity by which the listed item
is used in performing the actual maintenance
function. This measure is expressed by a two-
character alphabetical abbreviation, e.g., ea, in,
pr, etc., and is the basis used to indicate quantities
and allowances in subsequent columns. When the
unit of measure differs from the unit of issue, the
lowest unit of issue that will satisfy the required
units of measure will be requisitioned.
e. Quantity Incorporated
in
Unit.
Indicates the
quantity of the item used in the breakout shown
in the illustration figure, which is prepared for a
functional group, subfunctional group, or an as-
sembly. A “V” appearing in this column in lieu
of a quantity indicates that no specific quantity is
applicable, e.g., shims, spacers, etc.
f. 30-Day DS/GS Maintenance Allowances.
Note.
Allowances in GS Column are for GS Maintenance
only.
(1) The allowance columns are divided into
three subcolumns. Indicated in each subcolumn,
opposite the first appearance of each item in each
category of maintenance, is the total quantity of
items authorized for the number of equipments
supported. Subsequent appearances of the same
item will have the letters “REF” in the applicable
allowance columns,
indicating total allowance
quantities will be shown with the first appearance
of the item when shown as a supply item. Items
authorized for use as required but not for initial
stockage are identified with an asterisk in the al-
lowance column.
(2) The quantitative allowances for DS/GS
levels of maintenance will represent initial stock-
age for a 30-day period for the number of equip-
ments supported.
(3) Determination of the total quantity of
parts required for maintenance of more than 100
of these equipments can be accomplished by con-
verting the equipment quantity to a decimal fac-
tor by placing a decimal point before the next
to last digit of the number to indicate hundredths
and multiplying the decimal factor by the parts
quantity authorized in the 51-100 allowance col-
umn.
Example.
authorized allowance for 51-100
equipments is 40; for 150 equipments multiply
40 by 1.50 indicating 60 parts required.
g. 1-Year Allowances Per 100 Equipments/
Contingency Planning Purposes.
This column in-
dicates opposite the first appearance of each item
the total quantity required for distribution and
contingency planning purposes. Subsequent ap-
pearances of the same item will have the letters
“REF” in this column when shown as a supply
item. The range of items indicates total quantities
of all authorized items required to provide for
adequate support of 100 equipments for one year.
h. Depot Maintenance Allowance Per 100 Equip-
ments.
This column indicates opposite the first
appearance of each item the total quantity au-
thorized for depot maintenance of 100 equipments.
