This is a sole source requirement for two aircraft exhaust ducts (NSN 1RM 2840 016958298 H5, part number 06309-02813-103), as the government lacks sufficient data to contract with other than the current source. The items are subject to Free Trade Agreements and the WTO Government Procurement Agreement. These items require Government Source Approval prior to award, and approval for a new source typically cannot be completed in time for award. Interested parties that are not already approved sources must submit all required source approval data from the NAVSUP WSS brochure to be considered. For questions, contact Casey Brown at the provided email address.
