Description: The notice covers repair/modification of 10 butterfly valves, NSN 7R-4820-014729777-KB, TDP version 002, with delivery FOB origin. It requires prior Government source approval because the item is flight critical and/or the available technical data has not been determined adequate for full and open competition, and it states that only previously approved sources have been solicited. Unapproved sources may submit the information described in NAVSUP WSS source-approval brochures, but the notice is not a request for competitive proposals.
