Risk Acceptance and Safety Documentation Review  Section 6  6.2  Scope of NAS Changes  6.2.1  Local Implementation of National NAS Changes  87 6.2_SMSM_201607  Originally published July 2016  Uncontrolled copy when downloaded 1. AJI will typically identify these types of changes. When the local implementation of a nationally scoped SRM document cannot follow the national  standard, local SRM is required to assess and accept any risk for local deviations. If formal  waivers are required in such cases, local SRM does not eliminate the waiver requirement.  Note: Many systems and facilities that provide service in the NAS are not procured, owned, or  maintained by the FAA or another federal entity. The FAA has the authority and responsibility to  assure the safety of these services in accordance with Title 49 of the United States Code §  44505,  Systems, procedures, facilities, and devices , and Title 14 of the Code of Federal  Regulations Part 171,  Non-Federal Navigation Facilities . Although a system/service may not be  procured by the FAA, implementation into the NAS is considered a NAS change and requires  appropriate safety assessment, approval, and risk acceptance as if the FAA were acquiring the  system/service.  In cases where a NAS change affects two adjacent Service Delivery Points in different Service  Areas or a single Terminal Radar Approach Control / Air Route Traffic Control Center with more  than two underlying Airport Traffic Control Towers, the change proponent has the authority to  determine if the change will be considered local or national in scope.  A NAS change is considered to be local if:  Note: There may be cases in which an AJI safety case lead facilitates a local SRM panel and  none of the aforementioned criteria apply. These changes will be considered local.  National Airspace System (NAS) changes are considered either local or national. A national  NAS change is one for which a Safety and Technical Training (AJI) safety case lead facilitates  or leads the Safety Risk Management (SRM) effort or that meets at least one of the following  criteria:  • The NAS change has high visibility or a potential political, economic, or financial impact to the Federal Aviation Administration (FAA), the NAS, or the flying public. 1 • The NAS change is the result of financial or operational decisions made by FAA executive management, Cabinet-level executives, or Congress. • The NAS change includes means to reduce any safety risk identified as part of the Top 5 Program. • The NAS change modifies safety policy that must be incorporated into a directive. • The NAS change could or does present operational or technical conflicts to multiple affected Service Units or FAA Lines of Business. • The NAS change will be implemented on a national level, affecting multiple facilities. • It does not meet any of the preceding criteria and it affects three or fewer Service Delivery Points within a single Service Area or • It is a change proposed by Technical Operations that involves a single piece of equipment that is restricted to one district.
