The Safety Analysis and Risk Mitigation Process  Section 3  3.2.2.2  NAS Change Proposals  3.2.2.3  Examples of NAS Changes Unlikely to Require a Safety Analysis The configuration management requirements from the NAS Change Proposal process may not  specifically relate to safety effects. When a NAS change covered by a NAS Change Proposal  requires SRM, the appropriate safety analysis and documentation must be included in the  material provided to the Configuration Control Board. In terms of SRM, a NAS Change  Proposal can be categorized as one of the following:  For more information on NAS Change Proposals, refer to FAA Order 1800.66,  Configuration  Management Policy .  The following list presents NAS changes that will likely not require SRM. It is not a complete list  or explanation of all NAS changes that do not require a safety analysis. Contact the AJI safety engineering team manager via the SMS mailbox for assistance  determining if a safety analysis is required.  • Maintenance actions, as specified in maintenance technical handbooks • Installation or moving of equipment if defined installation siting processes are not violated • Changes to directives for those directives with no safety functionality • System Support Directives that do not change requirements and have followed AMS development assurance processes • Facility layout/redline/end-state drawings (e.g., Air Route Surveillance Radar, Air Traffic Control Tower, Terminal Radar Approach Control Facility, Air Route Traffic Control Center), as identified in the Configuration Control Board Charter, Appendix A • Not requiring any safety assessment • Requiring a complete safety analysis by an SRM panel and an SRM document (refer to Section 5) 2 4  3.2_SMSM_201904  Originally published April 2019  Uncontrolled copy when downloaded
