AI Summary

The Aviation Source Approval and Management Handbook outlines policies and procedures for approving sources for aviation parts, particularly Critical Safety Items (CSIs). It details various types of sources considered for approval, including prime contractors, OEMs, licensed manufacturers, distributors, and alternate sources. The handbook emphasizes the importance of full and open competition while ensuring high-quality, conforming items. Key aspects include managing CSIs from unapproved sources, source reciprocity among military services, and handling sources identified on control drawings. The document also addresses local purchase and repair, government manufacture of CSIs, and the use of surplus materials. It distinguishes between reverse engineering (replicating an item) and reengineering (creating a new design). The handbook further explains the Parts Manufacturer Approval (PMA) process and the responsibilities of procuring activities and Engineering Support Activities (ESAs) in source management and the Source Approval Request (SAR) review process, covering engineering, manufacturing, and quality assurance.
