The Naval Air Warfare Center Aircraft Division in Lakehurst, NJ intends to sole-source procure three PXI Discrete Input Cards from North Atlantic Industries Inc. in Bohemia, NY, as a replacement for obsolete VXI cards. This procurement is justified under FAR 6.302-1, as NAI holds exclusive intellectual property rights and is the only vendor capable of meeting the government's requirements. The cards are needed as spares to support the Fleet based on predicted failures from reliability analysis of the legacy Engine Test Instrumentation system. Responses expressing interest must be received within 15 days of the notice's publication. No budget amount or performance location beyond the vendor's site in Bohemia, NY, is specified.
