The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking proposals for the procurement of 95 units of the Cylinder Assembly, NSN 7R-1680-015677350-CB, which is critical for flight operations. The procurement requires that the item be sourced from approved suppliers as specified in the source control or selected item drawing, due to the lack of available technical data or government data rights for alternative sources. Interested vendors must submit their proposals along with necessary documentation for source approval, as the government intends to negotiate with only one source under FAR 6.302-1, with a deadline for proposals set at 45 days from the notice publication date. For further inquiries, interested parties can contact Michelle B. Toughill at (215) 737-3747 or via email at michelle.toughill@dla.mil.
