Purpose. To define the Naval Air Systems Command (NAVAIR) Reliability-Centered Maintenance (RCM) Program and establish RCM Program policy, and responsibilities within NAVAIR. 2. Cancellation. This instruction cancels NAVAIRINST 4790.20B. 3. Scope. This instruction applies to: a. All of NA VAIR, which includes NA VAIR Headquarters; Competencies, the Program Executive Officers, Program Managers, AIR, and subordinate commands. All new procurement and in-service aircraft, unmanned aerial systems, aeronautical equipment, engines, systems (e.g., airborne weapons, targets, trainers, training equipment, aircrew escape systems, armament, structural components, wiring, avionics, aviation life support systems, photographic equipment, imaging and reconnaissance equipment, meteorological equipment, air traffic control equipment and electrical systems), and peculiar and common support equipment (SE), including their modification, during all life cycle phases and levels of maintenance. b. Commercial and non-developmental systems and equipment for which support is required. 4. Definition. RCM is an analytical process to determine the appropriate failure management strategies, including Preventive Maintenance (PM) requirements and other actions that are warranted to ensure safe operations and cost-wise readiness. 5. Policy. PM requirements must be developed using RCM analysis procedures that comply with reference (a) as detailed in reference (b). RCM principles must be applied in conjunction with system-specific service life and airworthiness criteria (as part of the Systems Engineering
process) to ensure safety and cost-wise readiness through determination of appropriate failure management strategies. These strategies ensure the proper balance of manual PM tasks, prognostics and diagnostics (e.g., predictive and detective sensing devices), corrective maintenance, operational procedures, maintenance improvements, design changes, and training. A RCM Progra:m Plan must be developed and implemented to identify resources and actions required to develop and sustain the RCM program throughout the life cycle of the equipment per reference (b ). The NA VAIR RCM Steering Committee is required to review the RCM Program Plan prior to execution for assessment of effectiveness and implementation of lessons-learned. a. New acquisition and modification programs must use the RCM process to develop and document PM requirements consistent with the original aircraft certification basis. b. RCM must be used to update failure management strategies. A documented RCM analysis that includes justification (whether safety, cost, or operationally-driven) supporting the selected failure management strategy must be used to demonstrate the impact of revised PM requirements on future Fleet labor and repair costs and to add, delete, or modify any PM requirements. All available information, including fleet and operational data, must be utilized to perform this analysis. In cases where the analyst is unable to gather sufficient data to perform a valid RCM analysis, the analyst must consult the relevant competency, Integrated Product Team (IPT), or NA VAIR RCM Steering Committee for guidance. c. Any PM program, which was determined by an analysis process other than the current reference (b) process, may be sustained using the original method with the approval of Design Interface and Maintenance Planning Department (AIR-6.7.1). d. Aircraft launch and recovery equipment is managed as part of the ship's reliabilitycentered maintenance program, and as such is governed by the active Naval Sea Systems Command RCM military standard (MIL-STD-3034) versus this NA VAIR instruction. L e. Analyses must be documented directly into the Integrated Reliability-Centered Maintenance System (IRCMS) software or documented in a data format capable of being imported into IRCMS. 6.
