The Government requires 22 each of NSN 1R-3110-013997533-DQ, with delivery FOB Origin, and the item must be acquired from or repaired by a source specified on a source-control or selected-item drawing. Suitable technical data, Government data rights, or manufacturing/repair knowledge are not available to permit acquisition/repair from other sources or qualification of a second source. Because the item is flight critical and technical data is inadequate for full and open competition, Government source approval is required prior to award and only previously approved sources have been solicited. The Government intends to solicit and negotiate with only one source under FAR 6.302-1; non-approved sources must submit the information required by the applicable NAVSUP WSS Source Approval Brochure with their offer, and incomplete submissions will not be considered. New source approval normally cannot be completed in time to delay award, though responsible sources may identify their interest and capability; this notice is not a request for competitive proposals.
