Reliability Centered Maintenance (RCM) is a process that determines the best policies for managing asset functions and failures. It considers all asset management options like condition monitoring, scheduled restoration, and scheduled discard. RCM provides the optimal mix of reactive, time-based, condition-based, and proactive maintenance practices. When applied to commercial airlines in the 1970s, RCM reduced equipment-related crashes from 40 to 0.3 per million take-offs.

Reliability Centered Maintenance (RCM) RCM is a process to help people determine the best policies for managing the functions of physical assets—and for managing the consequences of their failures. Society of Automotive Engineers (SAE) has developed a standard, to provide criteria that can be used to evaluate a maintenance-program-development process and determine whether it is RCM process or not.

4. 1965: Studies show scheduled overhaul of complex equipment has little or no effect on in-service reliability 1970: RCM had its beginning in the commercial airline sector in 1970's. At that time, the commercial airline industry was experiencing high number of crashes in the take-offs which majority of them was related to equipment failures After applying the RCM method, it proved to be highly successful; in commercial airlines it reduced crashes from 60 per million take-offs to only 2 per million and more important than that reduced the equipment related crashes from 40 per million to only 0.3 per million take-offs.
