MIL-STD-3034, DEPARTMENT OF DEFENSE STANDARD PRACTICE: RELIABILITY-CENTERED MAINTENANCE (RCM) PROCESS (21 JAN 2011) [SUPERSEDES MIL-P-24534A (IN PART)]., Maintenance (preventive, corrective, and inactive) (see 3.13.1, 3.13.2, and 3.13.5) is the action of performing tasks (time-directed, condition-directed, failure-finding, servicing, and lubrication) (see 3.20.2, 3.20.5, 3.20.6, 3.20.7, and 3.20.8) at periodicities (periodic, situational, and unscheduled) to ensure the item抯 functions (active, passive, evident, and hidden) (see 3.11.1, 3.11.2, 3.11.3, and 3.11.4) are available until the next scheduled maintenance period. This standard describes the Reliability-Centered Maintenance (RCM) methodology used for the determination of maintenance requirements. It applies to all levels of system or equipment grouping, and to all scheduled maintenance, whether equipment is in use, ready for use, or in standby or lay-up condition. RCM addresses the total scheduled maintenance program for an enterprise, irrespective of the maintenance echelon possessing the capability to perform the maintenance; that is, organizational, intermediate, and depot level maintenance. This standard provides the procedure to develop preventive, corrective, and inactive equipment maintenance (see 3.13.1, 3.13.2, and 3.13.5) within a planned maintenance management system. Specific maintenance procedures may be developed, after the application of the RCM procedure outlined in this standard, for inclusion in class maintenance plans, and depot, intermediate, and organizational maintenance systems. This standard supersedes Phases 1 through 11 of MIL-P-24534A Amendment 1.
