This document outlines the process for submitting Source Approval Requests (SARs) related to national stock numbers (NSNs) to the Defense Logistics Agency (DLA). It specifies that SARs must be submitted through the DOD SAFE file transmission site and provides instructions for initiating electronic submissions. The document clarifies that SARs will not be considered for items already deemed fully competitive, nor will submissions be accepted via physical media. To optimize the efficiency of the submission process, the document urges potential submitters to evaluate item demand through the DLA Supplier Requirements Visibility Application before proceeding, as low demand may render submissions unviable. Additionally, it details the expected review timeline of over 180 days, with subsequent formal notification of the decision. The inclusion of guidelines and systems for checking the management and usage of the NSN reinforces the structured approach towards SAR submissions. Overall, the document serves as a procedural guide for stakeholders in navigating the SAR submission amidst federal procurement contexts, particularly for military supplies and services.

The Aviation Source Approval and Management Handbook outlines the procedures and policies for managing sources of supply for aviation-related components deemed as Critical Safety Items (CSIs). Key topics include the approval processes for suppliers, the responsibilities of procuring activities, and specific requirements for Source Approval Requests (SAR). The handbook emphasizes adherence to various regulations such as the Competition in Contracting Act and the Federal Acquisition Regulation, ensuring all sources contribute to effective competition and quality assurance. The document is structured into multiple chapters detailing information from general sourcing principles, the responsibilities of procurement and source management, the SAR process, to technical reviews and quality assurance requirements. Additional guidance covers reverse engineering, surplus procurement, and local purchasing abilities. Notably, the handbook advocates for reciprocal recognition of approved sources across military services, permitting efficiency in procurement. It details rigorous evaluations necessary for new supplier approval while maintaining high standards for safety and quality, thereby underscoring the government's commitment to ensuring reliability in aviation supplies. This comprehensive approach aligns with broader federal guidelines to enhance competitive sourcing and compliance within government contracts, federal grants, and state/local RFPs.
