This opportunity is for the repair of a flight-critical item (NSN 1R-9999-LLJMPZ995-QE, quantity 2) with delivery FOB Origin. The government lacks sufficient data to purchase this part from any source other than the currently approved supplier. Only previously approved sources have been solicited, and new source approval cannot be completed in time to avoid delaying the award. To be considered, any non-approved source must submit all required data from the NAVSUP WSS Source Approval Brochure with their proposal. The government intends to negotiate with only one source, but all proposals received within 45 days of this synopsis will be considered.
