The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking proposals for the procurement of 73 units of the Servocylinder Assembly, identified by NSN 7R-1650-014552591-QF and reference number 41010260-106. This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, as the technical data required for full and open competition is not adequately available. Interested vendors must provide comprehensive documentation to demonstrate their qualifications, including any prior submissions for source approval, and must be aware that the timeline for new source approval may affect the procurement process. For further inquiries, Aleida Marte can be contacted at (215) 737-7175 or via email at ALEIDA.MARTE@DLA.MIL.
