If a U.S. Navy sensor has a design problem, can the contractor be required to fix the sensor at no additional cost since the Navy approved the design at critical design review? The nonconformance was found during the initial production and no inspections have been performed on the sensor. What would be the least likely example of a form that would be used to document acceptance and define what type of defect would apply to this problem if the sensor has already been accepted by the Navy?
