The Department of Defense, through the Naval Supply Systems Command (NAVSUP) Weapon Systems Support, is seeking proposals for the procurement of 26 units of the Trim Servo Assembly, Air, under a sole source solicitation. The specific item, identified by NSN 7R-1680-014967283 and part number 70400-02260-123, is critical for various aircraft operations, and the government currently lacks sufficient data to contract with sources other than the approved supplier. Interested vendors must ensure they are an approved source and submit the necessary 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.
