The document outlines the process for submitting Source Approval Requests (SARs) within the Department of Defense (DoD) for items associated with national stock numbers (NSNs). For open solicitations, submissions should be directed to the specific buyer mentioned. SARs cannot be submitted for fully competitive items marked with AMSC "G." For items without open solicitations, submissions must be made electronically through the DoD SAFE site as CDs are no longer accepted. Interested parties must email a request to the DLA Aviation, providing necessary identifiers such as CAGE code and NSN. The review process may take over 180 days, and decisions are communicated via formal letters. The document emphasizes the need for evaluating the cost-effectiveness of SARs based on item demand, directing users to the DLA Supplier Requirements Visibility Application for forecasting data. It encourages the use of the PUB LOG FLIS tool to check the management of NSNs across services. Overall, this procedural guidance supports the efficient handling of SAR submissions in compliance with federal procurement standards.

The Aviation Source Approval and Management Handbook, published on March 16, 2011, outlines the processes and responsibilities for managing source approvals related to aviation Critical Safety Items (CSIs) and other aviation parts used by the Department of Defense (DoD). The handbook details types of sources considered for approval, including prime contractors and original equipment manufacturers, and specifies that only approved sources shall be contracted for CSIs. It emphasizes the policies established by the Competition in Contracting Act and Federal Acquisition Regulation to ensure fair competition while ensuring that approved suppliers meet technical and quality requirements. Key components include Source Approval Request (SAR) processes, risk management, and reviews covering technical data adequacy, manufacturing capabilities, and quality assurance. The handbook also addresses reverse engineering and reengineering considerations, local repairs, and the cautious procurement of surplus materials. Sources proposing alternate or reverse-engineered parts must demonstrate substantial equivalency and undergo stringent review. This document serves as a guide for government agencies and defense contractors in maintaining aerospace safety and operational integrity through rigorous source management and quality assurance protocols in alignment with federal regulations and policies.
