## 3.2.2.2 NAS Change Proposals 

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: 

• Not requiring any safety assessment 

• Requiring a complete safety analysis by an SRM panel and an SRM document (refer to Section 5) 

For more information on NAS Change Proposals, refer to FAA Order 1800.66, Configuration Management Policy . 

## 3.2.2.3 Examples of NAS Changes Unlikely to Require a Safety Analysis 

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. 

• 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 

• System Support Directives that do not change requirements and have followed AMS development assurance processes 

• Changes to directives for those directives with no safety functionality 

• Installation or moving of equipment if defined installation siting processes are not violated 

• Maintenance actions, as specified in maintenance technical handbooks
