This document outlines the procedures for submitting Source Approval Requests (SARs) to the Defense Logistics Agency (DLA) Aviation. It specifies that SARs for national stock numbers (NSNs) with open solicitations should be directed to the designated buyer; however, SARs for items already deemed fully competitive will not be processed. For NSNs without open solicitations, submissions must be made electronically via the DOD SAFE file transmission site, eliminating the need for physical CDs. Submitters must email a request to the DLA for a drop-off link and must include their CAGE code, NSN, and designated email address. The document emphasizes checking item demand viability before submitting a SAR, noting that SARs might not be processed if deemed non-cost-effective. Users are directed to the DLA Supplier Requirements Visibility Application for forecasting requirements and to the PUB LOG FLIS for data on NSN management by various military services. The SAR review process may take more than 180 days, and results will be communicated via formal notification. For inquiries, contacting a DLA analyst via the provided email is encouraged. The overall aim is to streamline SAR submissions and ensure efficient processing through electronic means.

The "Aviation Source Approval and Management Handbook" provides comprehensive guidance on the approval and management of sources for aviation parts classified as Critical Safety Items (CSIs). It outlines the policies and procedures necessary to ensure that all suppliers meet rigorous quality standards, aligning with federal laws such as the Competition in Contracting Act. The handbook emphasizes the importance of sourcing from approved vendors, whether prime contractors, manufacturers, or authorized distributors, to maintain safety and operational integrity. Key sections address the Source Approval Request (SAR) process, detailing risk management, technical reviews, and the necessity for quality assurance measures. It emphasizes that all newly proposed suppliers must demonstrate the capability to consistently produce acceptable items, articulating the process for source validation, disqualification, and government manufacture of critical items. Additionally, the document articulates the importance of reciprocity among military services regarding source approvals and the conditions under which local purchases and repairs of CSIs may occur. The handbook serves as a vital resource for ensuring that aviation-related procurements comply with established standards and protocols to facilitate safe and efficient operations within the Department of Defense.
