• Identify appropriate SRM panel members by consulting with the SRM panel facilitator. • Identify a facility/organization/program/technical lead (i.e., a Subject Matter Expert (SME)). • Identify an SRM panel facilitator, if necessary. • Coordinate with other organizations that may be affected by the NAS change or the potential risk management strategies. • Decide the extent to which SRM must be performed and/or documented. • Scope the operational system and/or environment affected. • Clearly define the NAS change or existing safety issue. SRM is needed to address confirmed existing safety issues identified in the NAS (e.g., Top 5  safety issues and other issues identified in national Corrective Action Requests). When  addressing existing safety issues, the hazard and its risk level may be pre-determined. It is not  necessary to reassess the validity or current risk level of any existing safety issue identified and  confirmed by a safety audit or post-event safety risk analysis. The purpose of performing SRM  on existing safety issues is to identify safety requirements or other actions to reduce the  associated risk to an acceptable level. At minimum, apply SRM to the existing safety issue;  however, the risk assessment should also account for the risk impact of any proposed safety  requirements.  The change proponent, along with a small group of technical experts, must properly define the  purpose and scope of the NAS change (see Section 5.3). The group should follow the guidance  and requirements in Section 3.1.1 to determine the impact of the NAS change on relevant NAS  equipment, operations, and procedures. After defining the scope and purpose of the NAS change, the change proponent and a small  group of technical experts should determine if there are any potential safety hazards associated  with the NAS change or if the NAS change could increase risk associated with NAS equipment,  operations, and/or procedures. Review Section 3.4 for assistance in determining the existence  of safety hazards associated with the NAS change. When the NAS change does not have the  potential to affect safe provisioning of air traffic management, communication, navigation, and/or  surveillance services, no further analysis is required. Conversely, if there is potential for the  63 5.2_SMSM_201904  Originally published April 2019  Uncontrolled copy when downloaded 5.2.1.2 Detecting Potential for Hazards  5.2.1.1 Scope  5.2.1 Planning and Initial Decision-Making  5.2 Preparing a Safety Analysis  Preparing, Performing, and Documenting a Safety Analysis  Section 5  The scope of a Safety Risk Management (SRM) effort is based on the type, complexity, and  effect of the National Airspace System (NAS) change or existing safety issue. It is critical that  the level of detail in a safety analysis matches the scope and complexity of the associated  NAS change or existing safety issue (see Section 3.3.2.4). To support this activity, the change  proponent for the SRM effort should consult his or her Service Center Quality Control Group,  the Safety and Technical Training (AJI) Safety Engineering Team Manager (who can be  contacted through the Air Traffic Organization (ATO) Safety Management System (SMS)  mailbox), or a local safety point of contact when initiating the process. The following steps are  essential to performing any initial decision-making, as well as planning and preparing for a  safety assessment of all NAS changes and existing safety issues:
