{"abstract":"This final rule limits the number of commercial air tours that may be conducted in the Grand Canyon National Park Special Flight Rules Area (SFRA) and revises the reporting requirements for commercial air tours in the SFRA. These changes allow the FAA and the National Park Service (NPS) to limit and further asses the impact of aircraft noise on the Grand Canyon National Park (GCNP). In addition, this action adopts non-substantive changes to 14 CFR part 93, subpart U to improve the organization and clarity of the rule. This rule is one part of an overall strategy to control aircraft noise on the part environment and to assist the NPS to achieve the statutory mandate imposed by the National Parks Overflights Act to provide substantial restoration of the natural quiet and experience of the park.","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/2000/04/04/00-7949.html","cfr_references":[{"chapter":null,"citation_url":null,"part":93,"title":14}],"citation":"65 FR 17708","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date for the final rule is May 4, 2000.","disposition_notes":null,"docket_ids":["Docket No. FAA-99-5927","Amdt.
