Gulfstream V Nadir Viewport Installation

This is modification 3 to the synopsis titled Gulfstream V Nadir Viewport Installation (GVNVI), Solicitation Number 80JSC017GVDIV, which was originally posted on July 21, 2017. The purpose of this modification is to revise the North American Industry Classification System (NAICS) code for this synopsis, from 488190 - Other Support Activities for Air Transportation to 336411 - Aircraft Manufacturing. After careful consideration of the requirements, the National Aeronautics and Space Administration (NASA) Johnson Space Center (JSC) has determined that the general scope of services to be provided for the Gulfstream V viewport installations are those services generally defined within the NAICS system as provided in industry Sector 336, Transportation Equipment Manufacturing, rather than Sector 488 for Support Activities for Transportation. NASA JSC anticipates awarding the GVNVI contract to a firm that primarily provides one or more of the following: (1) manufacturing or assembling complete aircraft; (2) developing and making aircraft prototypes; (3) aircraft conversion (i.e., major modifications to systems); and (4) complete aircraft overhaul and rebuilding (i.e., periodic restoration of aircraft to original design specifications). The Government's market research suggests that the specific NAICS code of 336411, Aircraft Manufacturing, would best represent the primary services to be provided under the anticipated GVNVI contract. Based on the selection of NAICS code 336411, it is anticipated that the GVNVI solicitation will be a small business set-aside. The due date for responses to this Request for Information has not been extended.
