Special Stockage Indicator Code and Replacement Factor (Column 3). (1) Special stockage indicator code. This column reflects the condition under which certain maintenance parts (parts assigned NSN’s and coded in the “P” series source code of the SMR code), are stocked. The codes are explained as follows: Code Definition No Code Indicates that the part may or may not be authorized in initial allowances to using or supporting organizations, The manner of determining initial allowances is explained in paragraph (2) below. 1 Applied to maintenance parts for which predicted consumption would not warrant inclusion in Mount-Out, but for which a quantity of one (1) is authorized as insurance of Mount-Out using a 360-day criteria. This criteria is based on the total density of equipments employed by the DIV/WING TEAM. Mount-Out allowances, so authorized, will be stocked by the FSR or the MWSG in the case of Marine Wing peculiar equipment, as applicable. D T Applied to maintenance parts that are not considered critical or essential to be on hand and are, therefore, not authorized in initial allowances; however, these items are stocked within the Supply System and may be requisitioned based upon usage. Indicates that the part is authorized in garrison operating allowances in order to comply with state and local laws; however, the part is not authorized in Mount-Out since it is not combat essential. (2) Replacement factor. This column reflects the replacement factor assigned to each nationally stock numbered maintenance repair part. This factor is assigned to the repair part on its first appearance in the publication. The replacement factor, expressed as a decimal, indicates the average rate at which the type of item so coded has been used by Marine Corps field units or the rate at which design engineers anticipate the item will fail, wear out, or otherwise require replacement. All computations are based on a replacement period of one year. Therefore, a replacement factor of 0.08, applied to an item in this stock list, indicates that eight out of every one hundred of such items used in the end item of equipment to which this publication pertains, are predicted to need replacement in one year. Likewise, 0.004 reflects that four out of every thousand in use are predicted to require replacement in one year, while 2.0 shows that every one in use is predicted to be replaced twice during each year. 1-7
