When serious questions began to be raised as to the. Federal. Aviation Administration FAA and the airline industry formed. Maintenance Steering Group to develop a new approach for establishing. In 1. 96. 8, the MSG 1 guidelines were adopted for the Boeing. New versions of these guidelines MSG 2 and EMSG 2. Based on experience with MSG 1 and MSG 2 and with the multi national. U. S. Navy, a revised approach was developed. The MSG 3 guidelines were adopted in 1. Currently, the Air Transport Associations. ATA OperatorManufacturer Scheduled Maintenance Development. MSG 3 Revision 2. FAA. and similar regulatory authorities in other countries as a. MSG 3 Guidelines. The MSG 3 guidelines take a top down approach that looks. Based on this analysis, inspections. According to these guidelines, the objectives. To ensure realization of the inherent safety and reliability. To restore safety and reliability to their inherent. To obtain the information necessary for design improvement. To accomplish these goals at a minimum total cost, including. There are several entities involved in the development of. Maintenance. Review Board MRB, Industry Steering Committee ISC and Industry. Working Groups IWGs. Each of these groups consists of representatives. The IWGs perform the detailed analyses. ISC and MRB provide various levels of oversight. MSG 3 provides guidelines for systems and powerplant analysis. LHIRF analysis. The scheduled maintenance. The systems and powerplant analysis.

MSG 3 Systems and Powerplant Analysis Defining Maintenance. Significant Items MSIsThe first step in MSG 3 systems and powerplant analysis is. For each component, the analysts review. The analysts can then determine the maintenance significant. MSIs by answering the following questions Could failure affect safety on ground or. Could failure be undetectable or not likely. Could failure have significant operational. Could failure have significant economic. If the answer to any of these questions is yes, then according. MSG 3 guidelines, the item warrants specific analysis. The analysis. is performed at the lowest level of the system configuration. Define the Functions, Failures, Effects and Causes for Each. MSIIn order to determine the appropriate maintenance tasks for. MSI, the next step is to identify the functions that the. Next, for each function, the analysts. Then, for each. functional failure, the analysts determine the possible effects. The MSG 3 guidelines provide logic designed to assign each. Evident. Safety, Evident Operational, Evident Economic, Hidden Safety. Hidden Non Operational or Hidden Economic. This is referred. Figure 1. Figure 1 MSG 3 logic to categorize. For each functional failure effect, the next step is to identify. Once the functions, failures, effects and causes have. MSI and each functional failure effect. Task Selection and Assignment. For each potential failure cause, the MSG 3 guidelines provide. There are five types. LubricationServicing, OperationalVisual. Check, InspectionFunctional Check, Restoration and Discard. Depending on the category of the functional failure effect that. Is a lubrication or servicing task applicable and effective Is a check to verify operation applicable and effectiveIs an inspection or functional check to detect degradation. Is a restoration task to reduce the failure rate applicable. Is a discard task to avoid failures or to reduce the. Is there a task or combination of tasks that are applicable. The MSG 3 guidelines also provide definitions of the available. The Systems and Powerplant Analysis Report. When the analysis for a particular MSI has been completed. The reports for all MSIs in the aircraft can be combined. LHIRF analysis and. Maintenance Review Board MRB. For each. MSI, the systems and powerplant analysis report contains the. A list of the items included in the analysis and documentation. MSI selection decisions. Detailed description and operation documentation. Maintainability and reliability data for each item included. A hierarchical list that contains each function, failure. MSI. The failure effect categorization results for each functional. MSI. The task selection results for each cause that has been. MSI.
