• All charting specification changes prior to submission to the Inter-Agency Air Cartographic Committee for final signature (e.g., symbology, color changes in routes, route identifiers) 

• Airspace changes, including routes, airways, sectors, and the addition or deletion of a position or sector 

• Changes to policies, procedures, or NAS equipment for which training exists 

• Removal of or modifications/waivers to existing national and/or local training requirements that could affect the NAS or NAS operations, except for the purposes of individual performance management 

• Establishment of or modifications to the Technical Training orders, architecture, and curricula 

• Changes to the conditions of the assumptions during the SRM process (potential implications to initial risk must be reassessed) 

## 3.2.2 When a Safety Analysis May Not Be Required 

## 3.2.2.1 Overview 

Not all NAS changes require a safety analysis using the SRM process; there are exceptions. The change proponent must use the criteria in this section and  Section 3.2.1 to make this determination. 

A safety analysis using the SRM process does not need to be performed for NAS changes that are compliant with policies/processes that have undergone SRM and have been documented and approved by the appropriate management official. If these policies or procedures are changed, or if any NAS change deviates from these policies or procedures, a safety analysis must be performed using SRM to manage the safety risk. Note that editorial and administrative changes (i.e., any changes that do not affect the substantive elements of a procedure or system) do not require SRM. 

FAA and/or ATO documents (e.g., policies, directives, manuals, Standard Operating Procedures, Letters of Agreement, Letters of Procedure) for developing and implementing many routine and repeatable NAS changes could be considered compliant with the SMS, meaning that SRM was performed, documented, and approved. For example, routine procedures such as flight inspections are conducted in accordance with FAA Order 8200.1, United States Standard Flight Inspection Manual . If there are no changes to those procedures, then a safety analysis is not required. However, if there is a change to the frequency of flight inspections, a safety analysis is required. 

Modifications made to systems to meet initial operational specifications (e.g., Problem Trouble Reports) may not require additional assessments if the system specifications have undergone a documented safety assessment. The modification and testing processes must also be compliant with the SMS.
