Preface The Safety Risk Management Guidance for System Acquisitions (SRMGSA) applies to  acquisitions that have a potential effect on safety risk in the National Airspace System (NAS)  when the acquired systems are operationally fielded. The SRMGSA includes information  pertaining to  Federal Aviation Administration Acquisition Management System changes, Next  Generation Air Transportation System Portfolio Management, and Integrated Safety  Management. The body of the document contains only high-level policy and guidance  concerning Safety Risk Management (SRM) in acquisitions. More detailed guidance on how to  conduct specific analyses/assessments is contained in the appendices of this document.  Groups within the Air Traffic Organization (ATO) (e.g., Program Offices) must comply with the  SRMGSA when applying SRM to acquisitions that affect safety risk in the NAS. The SRMGSA  and all other current ATO Safety Management System (SMS) policy and guidance documents  are available on the ATO SMS website. Safety and Technical Training (AJI) is the focal  organization for determining how system acquisitions affect safety risk in the NAS. AJI is also  the Office of Primary Responsibility for the SRMGSA. All questions concerning this document  should be directed to 9-AJI-SMS@faa.gov. Preface_SRMGSA_202003  Originally published March 2020  Uncontrolled copy when downloaded  1
