## 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.
