The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for a sole source contract to procure 135 units of a specific bushing, identified by NSN 1R-1650-016633740-H5 and reference number NAS73-9E107. This procurement is critical as the items are integral components of aircraft hydraulic, vacuum, and de-icing systems, and the government lacks sufficient data to contract with sources other than the current supplier. Interested vendors must obtain Government Source Approval prior to award and submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. For inquiries, potential bidders can contact Casey M. Brown at (215) 697-3752 or via email at casey.m.brown20.civ@us.navy.mil.
