{"abstract":"This rule adopts new and revised airworthiness standards for the performance of transport category rotorcraft. The changes define more clearly the factors for determining takeoff, climb, and landing performance requirements. These changes provide an improved level of safety associated with recent technological advances in the design of turboshaft engines and rotorcraft.","action":"Final rule.","agencies":[{"raw_name":"Final Rule"},{"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/1996/05/10/96-11494.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"29","title":14}],"citation":"61 FR 21894","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"June 10, 1996.","disposition_notes":null,"docket_ids":["Docket No. 24802","Amendment No. 29-40"],"dockets":[],"document_number":"96-11494","effective_on":null,"end_page":21901,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1996/05/10/96-11494/airworthiness-standards-transport-category-rotorcraft-performance","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/96-11494?publication_date=1996-05-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1996-05-10/96-11494/mods.xml","not_received_for_publication":null,"page_length":8,"page_views":{"count":312,"last_updated":"2026-07-27 10:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1996-05-10/pdf/96-11494.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1996-05-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1996/05/10/96-11494.txt","regulation_id_number_info":{"2120-AB36":{"issue":"199604","html_url":"https://www.federalregister.gov/regulations/2120-AB36/airworthiness-standards-transport-category-rotorcraft-performance","title":"Airworthiness Standards; Transport Category Rotorcraft Performance","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=199604&RIN=2120-AB36&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2120-AB36"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T03:58:06Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":21894,"subtype":null,"title":"Airworthiness Standards; Transport Category Rotorcraft Performance","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":61}
