The FAA is conducting a market survey to identify potential sources for the acquisition of 515 single-channel and 55 dual-channel SSR Monitors for its ATCBI-6 radar systems, which are critical to avoiding extended outages in the National Airspace System. This is not a request for proposals, but a survey to gauge interest and capabilities for a future acquisition and to determine if the competition can be set aside for small businesses. Interested vendors must submit a detailed capability statement, including proof of rights to OEM data, past performance details, ISO 9001:2015 certification, and SAM.gov registration. Responses are for informational purposes only and must be submitted via email by a specified deadline. The notice also includes information about a DOT loan program for small and disadvantaged businesses.
