The document outlines the updated procedures for submitting Source Approval Requests (SARs) for national stock numbers (NSNs) within the Department of Defense (DoD). SARs can be submitted directly to the specified buyer of open solicitations, but items classified as fully competitive are excluded. The new process eliminates the mailing of CDs, instead utilizing the DoD SAFE file transmission site for electronic submissions. Interested parties must request a “drop off” via email to submit their SAR, including essential details like CAGE code and NSN. Potential submitters are encouraged to evaluate item demand through the DLA Supplier Requirements Visibility Application to ensure cost-effectiveness. Additionally, the document explains how to access and utilize the PUB LOG FLIS database for insights on item management across various services. The review period for SARs can exceed 180 days, leading to a formal notification upon decision-making. For further inquiries, an analyst contact is provided. Overall, the file emphasizes streamlining procedures while ensuring compliance and efficiency in federal procurement processes.

The "Aviation Source Approval and Management Handbook" outlines policies and procedures for managing and approving sources for aviation parts, particularly focusing on Critical Safety Items (CSIs). The handbook emphasizes promoting full and open competition in procurement, ensuring that all potential sources meet stringent technical and quality standards. It details specific categories of sources considered for approval, including OEMs, licensed manufacturers, and distributors, and establishes responsibilities for procuring activities in source management. Key chapters include guidelines on Source Approval Requests (SAR), reverse engineering processes, site surveys, and validation of sources. The document mandates that all CSIs, particularly from unapproved sources in existing inventories, undergo thorough evaluation and testing before approval. Moreover, it highlights the importance of maintaining a pool of approved sources to ensure operational readiness and safety in aviation operations, while also allowing for efficiency through source reciprocity among military services. The handbook serves as a comprehensive guide for government entities involved in sourcing and procurement for aviation parts, fostering safety, quality assurance, and compliance with regulatory frameworks.
