The document outlines the process for submitting Source Approval Requests (SARs) for national stock numbers (NSNs) within Department of Defense (DoD) procurement. SARs must be directed to the buyer listed in an open solicitation, and those for items already deemed fully competitive will not be evaluated. For NSNs without open solicitations, submissions must now be made electronically using the DoD SAFE file transmission site, effectively replacing mail-in CDs. Applicants should initiate their submission by emailing the DLA Aviation SAR analyst to receive a file drop-off link. The document emphasizes the importance of assessing item demand before submission, as low demand could result in non-processing of the SAR. It also outlines additional resources such as the DLA Supplier Requirements Visibility Application for forecasting requirements and the PUB LOG FLIS for tracking NSN usage across services. Notably, review times can exceed 180 days, and formal notifications will be provided upon decision completion. Overall, this updated process aims to streamline SAR submissions while ensuring effective management of procurement requests within government operations.

The Aviation Source Approval and Management Handbook outlines policies and procedures to ensure the safety and quality of critical aviation components in the U.S. military and government operations. It delineates source approval types, risk management, and responsibilities associated with source management activities. The handbook specifies the criteria for approving suppliers, including original equipment manufacturers, repair facilities, and licensed distributors. It also addresses how to manage sources of surplus materials and the processes for reverse engineering and parts manufacturer approval. Key responsibilities include ensuring all contracts comply with source approval requirements, evaluating historical sources, and addressing the technical qualifications and quality assurance measures of potential suppliers through Source Approval Requests (SARs). The document encourages collaboration among military services for efficient procurement processes and standardization of sourcing. It emphasizes the importance of maintaining airworthiness while optimizing financial resources and competition amongst suppliers, ultimately supporting the goal of providing safe and reliable aviation parts for defense operations.
