The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of FOLD HINGE ASSEMBLY and similar replacement parts. This requirement is classified as a sole source procurement, necessitating Government Source Approval prior to award, as the Government lacks sufficient data to contract with sources other than the current supplier. The items are critical components related to helicopter rotor blades and drive mechanisms, underscoring their importance in maintaining operational readiness. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, and inquiries can be directed to Kate Schalck at 215-697-1020 or via email at kate.n.schalck.civ@us.navy.mil.
