Secondary reviewers, as required, include: 

• Quality Control Group representatives from the Service Center, 

• Air Traffic Safety Oversight Services (AOV) Air Traffic Safety Standards Oversight, AOV-100, representatives,

The peer review timeline is dependent upon various factors including, but not limited to, the complexity of the safety analysis/assessment, the number of stakeholders involved, new technologies involved, prior reviews, and projected JRC decision dates. The AJI SCL negotiates with the PO for firm review dates, if possible, during the initial SSM. Timelines can be reduced if draft versions have been already reviewed. If comments cannot be resolved to the satisfaction of the original commenter, then the AJI SCL identifies them as issues for inclusion in the final briefing package provided to the ATO Chief Safety Engineer upon recommendation for approval by the AJI-314 Team Manager. 

Per Section 2.2.2, the Program Management Organization (AJM) must approve the following safety deliverables as required by the contract: the SHA, the SSHA, and the O&SHA (or the SAE Aerospace Recommended Practice (ARP) 3  ARP4754A, Guidelines for Development of Civil Aircraft and Systems , equivalents). Similarly, AJM must approve the following safety deliverables related to RTCA 4  DO-278A, Software Integrity Assurance Considerations for Communication, Navigation, Surveillance and Air Traffic Management (CNS/ATM) Systems : the Plan for Software Aspects of Approval, the final Software Configuration Index, the Software Accomplishments Summary, and any other related deliverables as required by the contract. Prior to AJM approval of a safety deliverable, the individual PO must send the safety deliverable to the AJI SCL to conduct a review and make any comments by the requested due date. The PO must also ensure that the safety deliverable is peer reviewed by appropriate subject matter experts. The PO must review and adjudicate the AJI SCL comments in parallel with the comments received during the peer review. After the AJM peer review process is completed and all comments are adjudicated, the safety deliverable may be finalized, approved, and signed in accordance with AJM procedures. 

## 8.4 Approval Authorities and Coordination Requirements 

The SMS Manual contains the guidance and coordination requirements for the review, approval, and risk acceptance of SRM documentation contained completely within a Service Unit (SU), across multiple SUs, or across multiple lines of business. SRM documentation may not be submitted to the ATO Chief Safety Engineer for approval until after it has undergone the AJI peer review process. However, SRM documents without hazards for an acquisition program that will undergo an Independent Operational Assessment must be submitted to AJI-321 for peer review. The ATO Chief Safety Engineer is also the approval authority for PSPs as well as
