{"abstract":"On June 12, 2024, the FAA published in the Federal Register a notice of availability for draft Advisory Circular (AC) 21.17-04, \"Type Certification of Powered-lift\". The comment period for this document expires on August 12, 2024. By letter dated August 1, 2024, the General Aviation Manufacturers Association (GAMA) requested that the FAA extend the public-comment period deadline to September 12, 2024. GAMA stated in their request that providing more time to comment would allow member organizations to conduct a more thorough review and contribute constructively to the proposed criteria facilitating the development of robust, harmonized standards that maximize safety for powered-lift operations.","action":"Notice of availability, request for comments; extension of comment period.","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/2024/08/09/2024-17720.html","cfr_references":[],"citation":"89 FR 65477","comment_url":"https://www.regulations.gov/commenton/FAA-2024-1586-0013","comments_close_on":"2024-09-12","correction_of":null,"corrections":[],"dates":"The comment period for the document published June 12, 2024, at 89 FR 50042, is extended.
