MAINTENANCE ASSISTANCE MODULES
Reference: P-485, CH. 6 Inventory Management

Maintenance Assistant Modules (MAMs) are defined as test modules required to execute an approved maintenance plan that calls for the identification of a fault through a progressive sequence of module substitution.

MAMs are in the custody of the cognizant department head and will be located in the appropriate operating and maintenance spaces under the sub custody of operating/maintenance personnel. MAMs are the joint responsibility of the Supply Officer and the cognizant department head.

The Supply Officer is responsible for ensuring all supply petty officers are trained on the stocking policy requirements of MAMs.

MAMs consist of those items identified in the COSAL by assignment of Allowance Note Code "N" and the establishment of a new COSAL Stock Number Sequence List (SNSL) segment to be identified as COSAL Part III, Section CF.

The Supply Officer will maintain a Stock Record Afloat (NAVSUP Form 1114m) for each MAM authorized on board. Replenishment by department heads will be through the Supply Officer on a one for one basis. MAMs will be inventoried semiannually and, when necessary issue request documents will be prepared to report consumption and to initiate replenishment of missing items for which replacements were not requested.

KEY POINTS:
- MAMs is defined as test modules required to execute an approved maintenance plan that calls for the identification of a fault through a progressive sequence of module substitution.
- MAMs are identified in the COSAL by Allowance note Code "N".

FEDERAL SUPPLY CLASSIFICATION SYSTEM

The Federal Supply Classification (FSC) is designed to permit the classification of all items of supply used by the government. Each item will be included in one, and only one FSC. The FSC is made up of 2 two digit numeric codes: the federal supply group and the federal supply class. The federal supply group identifies, by title, the commodity area covered by classes with the group. Each class covers a relatively homogeneous range of commodities.
