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 asterisk (*) in the allowance column.

(2)The quantitative allowances for organizational level of maintenance represent one initial prescribed load for a

15-day period for the number of equipments supported. Units and organizations authorized additional prescribed loads

will multiply the number of prescribed loads authorized by the quantity of repair parts reflected in the appropriate density

column to obtain the total quantity of repair parts authorized.

(3)Organizational units providing maintenance for more than 100 of these equipments shall determine the total

quantity of parts 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 multiplying the decimal factor by the parts quantity authorized

in the 51-100 allowance column. Example: authorized allowance for 51-100 equipments is 12; for 140 equipments,

multiply 12 by 1.40 or 16.80 rounded off to 17 parts required.
