The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking proposals for the procurement of 11 units of an antenna assembly, identified by NSN 7R-5985-015874866-P8 and reference number 131K876G01. This procurement is critical as it involves items classified as Critical Safety Items (CSI), necessitating compliance with specific government regulations, including the requirement for FAA-Certified parts and engineering source approval. The selected supplier must be an approved source, as the item is flight critical, and proposals from non-approved sources will be deemed technically unacceptable. Interested parties should contact Gina Palumbo at (267) 660-8638 or via email at GINA.PALUMBO@DLA.MIL for further details, with a proposal submission deadline of 45 days from the notice publication date.
