{"abstract":"This final rule provides new and revised airworthiness standards for normal and transport category rotorcraft due to technological advances in design and operational trends in normal and transport rotorcraft performance and handling qualities. The changes enhance the safety standards for performance and handling qualities to reflect the evolution of rotorcraft capabilities. This rule harmonizes U.S. and European airworthiness standards for rotorcraft performance and handling qualities.","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/2008/02/29/E8-3817.html","cfr_references":[{"chapter":null,"citation_url":null,"part":27,"title":14},{"chapter":null,"citation_url":null,"part":29,"title":14}],"citation":"73 FR 10987","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"These amendments become effective on March 31, 2008.
