that accepted the associated risks of the NAS change or existing safety issue must follow the monitoring plan documented in the SRM document. 

## 6.6.2 AJI Review and Approval 

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. 

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. 

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. 

## 6.6.2.1 AJI Participation in System Acquisition Safety Analyses 

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. 

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. 

The ATO Chief Safety Engineer reviews SRM documentation and the associated safety assessments, analyses, reports, and plans, providing approval or comments.
