{"abstract":"The FAA is amending the airworthiness standards for normal and transport category rotorcraft. The changes amend the airworthiness standards to require a cockpit indication of autopilot operating mode to the pilots for certain autopilot configurations, to clarify the burn test requirements for electrical wiring for transport category rotorcraft, and to provide a new requirement for an electrical wire burn test for normal category rotorcraft. The rule also adds a 1.33 fitting factor structural strength requirement to the attachment of litters and berths.","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/1998/08/12/98-21609.html","cfr_references":[{"chapter":null,"citation_url":null,"part":27,"title":14},{"chapter":null,"citation_url":null,"part":29,"title":14}],"citation":"63 FR 43282","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"September 11, 1998.","disposition_notes":null,"docket_ids":["Docket No. 28929","Amendment Nos. 27-35 & 29-42"],"dockets":[],"document_number":"98-21609","effective_on":"1998-09-11","end_page":43285,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1998/08/12/98-21609/harmonization-of-miscellaneous-rotorcraft-regulations","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/98-21609?publication_date=1998-08-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1998-08-12/98-21609/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":125,"last_updated":"2026-07-25 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1998-08-12/pdf/98-21609.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1998-08-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1998/08/12/98-21609.txt","regulation_id_number_info":{"2120-AG23":{"issue":"199804","html_url":"https://www.federalregister.gov/regulations/2120-AG23/harmonization-of-miscellaneous-rotorcraft-regulations","title":"Harmonization of Miscellaneous Rotorcraft Regulations","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=199804&RIN=2120-AG23&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2120-AG23"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T08:30:44Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":43282,"subtype":null,"title":"Harmonization of Miscellaneous Rotorcraft Regulations","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":63}
