## 8 Safety Risk Management Documentation, Approval, and Tracking 

## 8.1 Safety Risk Management Documents 1 

For an acquisition, the system safety process is a series of analyses/assessments that starts at the Operational Safety Assessment (OSA) and the Comparative Safety Assessment (CSA) and continues through the Preliminary Hazard Analysis (PHA), the Sub-System Hazard Analysis (SSHA), the System Hazard Analysis (SHA), the Operating and Support Hazard Analysis (O&SHA), and System Safety Assessment Report (SSAR). Each analysis/assessment becomes more discrete as more design details are known. The basis of each analysis/assessment is a Hazard Analysis Worksheet (HAW). 2 The HAW, initially developed early in the system lifecycle (i.e., in a PHA), is further developed, modified, and enhanced as subsequent analyses/assessments are conducted. Each subsequent analysis/assessment has a slightly different focus but is essentially a HAW in nature that builds on a previously developed HAW. 

Thus, the Safety Risk Management (SRM) document becomes a report, or a series of reports, that describes the SRM process that has been conducted with regard to a proposed change or investment. The SRM document records the safety risk analyses/assessments that were performed and the findings that detail the predicted risk level(s) of the proposed change or investment. It is a compilation of the SRM documentation completed to date. As such, the SRM document expands with each analysis/assessment as a product moves through the Federal Aviation Administration (FAA) Acquisition Management System (AMS) lifecycle. When it is determined at the Safety Strategy Meeting (SSM) that specific safety analyses/assessments are required, the analyses/assessments are documented and become part of the SRM document. Each Program Office (PO) must maintain an SRM document as a record of the progress of the project. 

In colloquial terms, imagine a folder titled “SRM document for Acquisition XXX.” Every analysis/assessment performed for this acquisition is titled “SRM document – (analysis/assessment name here)” and stored in the folder. Each analysis/assessment is an SRM document, but the entire folder is the SRM document for the acquisition. In conversation, especially when a milestone is approaching, questions may be raised about the status of the SRM document; in most cases, the requestor is concerned about the status of the most recent analysis/assessment rather than the entire folder. 

For safety documents required to be approved before a particular acquisition milestone decision point, the PO must record SRM document activity and information in the Safety Management Tracking System (SMTS) prior to that milestone. For other SRM documents (e.g., the SHA, SSHA, and O&SHA), SRM document activity and information must be recorded in SMTS within 30 days after document approval. (See Section 8.5 for details on what must be uploaded.) The PO must also upload a copy of the approved Program Safety Plan (PSP) to SMTS. 

If an acquisition change is not expected to introduce new hazards or increase safety risk into the National Airspace System (NAS), then there is no need to conduct further safety analyses; however, the PO must document this determination in an SRM document along with justification
