Regulations will go into effect October 17 to help ensure that replacement parts are airworthy. New FAR Part 3 creates additional rules banning certain false or misleading statements about type-certified parts that go beyond those now covered in Parts 21 and 43. In addition, Part 3 prohibits “intentionally misleading statements” about the airworthiness of parts. This includes any statement “that makes a representation as to the airworthiness or acceptability of a part, including advertisements, as well those records regularly relied upon by installers of equipment to ensure airworthiness.”
