The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is soliciting proposals for the procurement of DME Interrogator SE, a critical component in radio navigation equipment. The procurement requires suppliers to provide newly manufactured spares that meet specific FAA certification standards, as refurbished or remanufactured items will not be accepted. This solicitation emphasizes the importance of quality and compliance, particularly for critical safety items, and mandates that all offers must come from government-approved sources. Interested parties should direct inquiries to Alana Arthur at 215-737-8443 or via email at ALANA.ARTHUR@DLA.MIL, with proposals due by the specified deadline.
