 Risk Acceptance and Safety Documentation Review  Section 6  94 6.6_SMSM_201904  Originally published April 2019  Uncontrolled copy when downloaded The ATO Chief Safety Engineer reviews SRM documentation and the associated safety  assessments, analyses, reports, and plans, providing approval or comments.  The AJI safety case lead will ensure that all required safety documentation meets the  requirements of this SMS Manual and the Safety Risk Management Guidance for System  Acquisitions and will assemble the necessary subject matter experts to review the  documentation before it is presented to the ATO Chief Safety Engineer for approval.  AJI safety case leads will be involved with NAS change efforts from concept development  through In-Service Management. In coordination with the Office of NextGen, an AJI safety case  lead will be assigned to a portfolio, capture team, or program to provide safety guidance and  advice, as appropriate. The AJI safety case lead will be familiar with the portfolio, capture team,  or program; the program’s possible NextGen interfaces; its position within the Enterprise  Architecture; its milestones; and its safety documentation requirements. The AJI safety case  lead will stay with that portfolio, capture team, or program throughout its lifecycle.  When a NAS change or existing safety issue facilitated by AJI crosses Federal Aviation  Administration (FAA) LOBs/organizations, an AJI safety case lead reviews the assessments to  verify that affected LOBs/organizations have reviewed and approved the SRM documentation  for accuracy and correctness with regard to the NAS change or existing safety issue. When a  NAS change or existing safety issue facilitated by AJI crosses FAA LOBs, the ATO Chief Safety  Engineer must approve and sign the safety analysis.  Any documentation forwarded to the Air Traffic Organization (ATO) Chief Safety Engineer for  approval must first go through an AJI peer review. For an AJI peer review, forward SRM  documentation to the AJI safety case lead in draft form and without signatures. At this point, the  AJI safety case lead will facilitate the remaining steps in the review process. When the SRM  document is ready for signature, the AJI safety case lead will notify the change proponent, who  will obtain the appropriate signatures. Finally, when the SRM document has all signatures  except for that of the ATO Chief Safety Engineer, the AJI safety case lead will present the SRM  document to the ATO Chief Safety Engineer for signature. Other SRM document requirements  (see  Section 5.4.4.2) that are documented in this SMS Manual remain. that accepted the associated risks of the NAS change or existing safety issue must follow the  monitoring plan documented in the SRM document.  AJI review and approval is a technical and non-technical assessment by AJI safety case leads  to verify that the SRM process has been followed, that the safety documentation is complete,  and that the safety documentation adheres to the Safety Management System (SMS) Manual  principles and guidelines. 6.6.2  AJI Review and Approval  6.6.2.1 AJI Participation in System Acquisition Safety Analyses
