NAVSUP WSS intends to solicit on a sole source basis a flight display unit, NSN 7R 6610 016815999, part number 343A564-1, quantity 1. The Government states it lacks sufficient, accurate, or legible data to contract with any source other than the current one. The item(s) are subject to Free Trade Agreements and the WTO Government Procurement Agreement/Free Trade Agreements. Government source approval is required prior to award, and because approval of a new source normally cannot be obtained in time to avoid delaying award, non-approved sources must submit the information in the NAVSUP WSS Source Approval Brochure with their proposal; offers missing required data will not be considered.
