{"abstract":"The FAA amends the regulations governing airworthiness standards for transport category airplanes in six areas: miscellaneous flight requirements; powerplant installations; the public address system; trim systems; protective breathing equipment (PBE); and design requirements for powerplant valves controlled from the flight deck. Adoption of these amendments eliminates the regulatory differences between the airworthiness standards of the U.S. and the Joint Aviation Requirements (JAR) of Europe. Currently, airplane manufacturers must satisfy both the U.S. and European airworthiness requirements to certificate transport category airplanes in the U.S. and Europe. Because U.S. manufacturers of transport category airplanes already meet the more stringent requirements of the JAR, adoption of these amendments will not affect current industry design practices.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2004/07/02/04-15117.html","cfr_references":[{"chapter":null,"citation_url":null,"part":25,"title":14}],"citation":"69 FR 40520","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This amendment becomes effective August 2, 2004.","disposition_notes":null,"docket_ids":["Docket Nos.
