Background The intent of this document is to demonstrate that the RCM process provided in NAVAIR 00-25-403 is compliant with SAE JA1011. It should be noted that several of the authors of SAE JA1011 were NAVAIRSYSCOM employees at the time and were also authors of NAVAIR 00-25-403. It was their intent to create a document that would allow the use of the NAVAIR 00-25-403 process in contractsolicitations via the reference of commercial standard. It should therefore be evident that the authors would not have created a document that contradicted their own. To illustrate the connection with NAVAIR 00-25-403, the following is quoted directly from SAE JA1011 (page 1): “The criteria in this SAE Standard are based upon the RCM processes and concepts in three RCM documents: (1) Nowlan and Heap’s1978 book, Reliability-Centered Maintenance, US Naval Aviation’s MIL-STD-2173(AS) Reliability-Centered Maintenance Requirements of Naval Aircraft, Weapons Systems and Support Equipment and its successor, US Naval Air Systems Command Management Manual 00-25-403 Guidelines for the Naval Aviation Reliability-Centered Maintenance Process, and (3) Reliability-Centered Maintenance (RCM II) by John Moubray.These documents are widely-used RCM documents available.” While the above statements illustrate that a general assumption could be made that the NAVAIR 00-25-403 process is compliant with SAE JA1011 based on association and intent, the remainder of this document will demonstrate line by line and conclusively that this is the case. The final part of this document will address some specificpreviously raised concerns about the NAVAIR 00-25-403 process relative to SAE JA1011 compliance.
SAE JA1011 Requirements I. SAE JA1011 General RCM Process Requirements: The requirements for a process to be called RCM are provided in section 5 of SAE JA1011. The requirements are summarized at the beginning of the section as follows:
“5. Reliability-Centered Maintenance (RCM) - Any RCM process shallensure that all of the seven questions are answered satisfactorily and are answered in the sequence shown as follows: a. What are the functions and associated desired standards of performance of the asset in its present operating context (functions)? b. In what ways can it fail to fulfill its functions (functional failures)? c. What causes each functional failure (failure modes)? d. What happenswhen each failure occurs (failure effects)? e. In what way does each failure matter (failure consequences)? f. What should be done to predict or prevent each functional failure (proactive tasks and task intervals)? g. What should be done if a suitable proactive task cannot be found (default actions)? To answer each of the previous questions “satisfactorily”, the following information shall begathered, and the following decisions shall be made. All information and decisions shall be documented in a way which makes the information and the decisions fully available to and acceptable to the owner of the asset.” (SAE JA1011, page 6)
The following illustration, from the training material for NAVAIR 00-25-403 process, shows that the basic steps and sequence outlined above are included in theNAVAIR 00-25-403 RCM process:
