are economically reparable at DS/GS ac-
b. Federal Stock Number. Indicates the Federal stock number assigned to the item and will be used
for requisitioning.
c. Description. Indicates the Federal item name and any additional description of the item required.
Multiple application of an item is also listed within this column, quantities appearing before each ap-
plication. The manufacturer's reference number or identification number followed by the applicable
five-digit Federal Supply code for manufacturer's in parenthesis, are indicated in the subcolumm.
d. Unit of Issue. A two-character alphabetic abbreviation indicating the amount or quantity of the
item upon which the allowances are based; e.g.: EA, HD, PR, etc.
e. Quantity Incorporated in Unit. Indicates the quantity of the item used in the functional group.
The symbol V is used in this column to indicate that the quantity of an item is variable.
f. Fifteen-Day Organizational Maintenance Allowances.
(1) The allowance column is divided into four subcolumns. Indicated in each subcolumn opposite
the first appearance of each item is the total quantity of items authorized for the number of equip-
ments supported. Subsequent appearances of the same item will have an entry of REF in the allowance
column. Items authorized for use as required, but not for initial stockage, are identified with an as-
terisk (*) in the allowance column.
(2) The quantative allowances for organizational level of maintenance represents one initial pre-
scribed load for a 15-day period for the number of equipments supported. Units and organizations au-
thorized additional prescribed loads will multiply the number of presicribed loads authorizd by the
quantity of repair parts reflected in the appropriate density column to obtain the total quantity of re-
pair parts authorized.
(3) Organizational units providing maintenance for more than 100 of these equipments shall de-
termine the total quantity of pants required by converting the equipment quantity to a decimal factor by
placing a decimal point before the next to last digit of the number to indicate hundredths, and multi-
plying the decimal factor by the parts quantity authorized in the 51-100 alllowance column. Example:
authorized allowance for 51-100 equipments is 12; far 140 equipments multiply 12 by 1.40 or 16.80
rounded off to 17 parts required.

are considered necessary, recommendation should be forwarded to U. S. Army Aviation Systems Com-

asterick (*) in the allowance column.
(2) The quantitative allowances for DS/GS level of maintenance will represent initial stockage
for a 30-day period for the number of equipments supported.
(3) Determination of the total quantity of parts required for maintenance of more than, 100 of
these equipments can be accomplished by converting the equipment quantity to a decimal factor by plac-
ing a decimal point before the next to last digit of the number to indicate hundredths, and multiplying
