scope:

This instruction applies to acquisition, logistics, and maintenance activities for all new and legacy programs. CBM and CBM+ concepts, as described in reference (a), apply to all active and reserve naval ships, aircrafts, and the systems associated with them, as well as the infrastructure which supports them. Throughout this instruction, the term "ship" refers to all surface ships, aircraft carriers, submarines, and those patrol and service craft specified in reference (c). The fundamental goal of CBM is to perform maintenance only when there is objective evidence of need, while ensuring safety, equipment reliability, equipment availability, and reduction of total ownership costs (TOC). The evidence of need is objectively determined through RCM analysis.

Purpose

a. To establish policy and responsibility, per reference (a), for the implementation and integration of condition-based maintenance (CBM) and condition-based maintenance plus (CBM+) for naval ships, expeditionary equipment, aircraft, and associated systems, equipment and infrastructure.

b. This revision incorporates policy changes for implementing CBM+ and follows standards set by reference (a), and for implementing CBM+ within maintenance practices. It also includes new language for reliability centered maintenance (RCM) and CBM+ that is in line with references (a) and (b). This instruction is a complete revision and should be reviewed in its entirety.
