The Government seeks one flight-critical part (NSN 7R-1560-016898060-QF, reference 74A140001-1042, quantity 1 EA) with delivery FOB origin. The item requires engineering source approval by the design control activity, and only previously approved sources have been solicited because data rights and technical knowledge are not economically available to the Government. New sources must qualify under Government-approved procedures and submit the required NAVSUP WSS Source Approval Brochure information with their offer. The Government intends to solicit and negotiate with only one source under FAR 6.302-1, though responsible sources may identify interest and capability or submit proposals for consideration. Drawings are not available, and the acquisition will not use FAR Part 12 commercial-item policies.
