{"abstract":"This action proposes special conditions for the Robinson Helicopter Company (Robinson) Model R66 helicopter. This helicopter, as modified by Skyryse, will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for normal category helicopters. This design feature replaces the mechanical flight controls with a digital fly-by-wire (FBW) system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.","action":"Notice of proposed special conditions.","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/2026/04/21/2026-07714.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"27","title":14}],"citation":"91 FR 21268","comment_url":"http://www.regulations.gov/commenton/FAA-2025-5245-0001","comments_close_on":"2026-06-05","correction_of":null,"corrections":[],"dates":"Send comments on or before June 5, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2025-5245","Notice No. 27-26-01-SC"],"dockets":[{"supporting_documents":[],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-04-21","updated_at":"2026-04-21T10:01:16.393-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2025-5245-0001","allow_late_comments":false,"id":"FAA-2025-5245-0001","comment_end_date":"2026-06-06","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":0,"id":"FAA-2025-5245","title":"Skyryse, Robinson Helicopter Company Model R66 Helicopter; Flight Control System Annunciation of Control"}],"document_number":"2026-07714","effective_on":null,"end_page":21269,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/21/2026-07714.xml","html_url":"https://www.federalregister.gov/documents/2026/04/21/2026-07714/special-conditions-skyryse-robinson-helicopter-company-model-r66-helicopter-flight-control-system","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-07714?publication_date=2026-04-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-21/2026-07714/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":182,"last_updated":"2026-04-27 10:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-21/pdf/2026-07714.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-07714.pdf?1776689112","publication_date":"2026-04-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/21/2026-07714.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[],"comments_count":1,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2025-5245","supporting_documents_count":0,"docket_id":"FAA-2025-5245","document_id":"FAA-2025-5245-0001","regulation_id_number":null,"title":"Skyryse, Robinson Helicopter Company Model R66 Helicopter; Flight Control System Annunciation of Control","checked_regulationsdotgov_at":"2026-04-23T04:55:03Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2025-5245-0001","significant":null,"signing_date":null,"start_page":21268,"subtype":null,"title":"Special Conditions: Skyryse, Robinson Helicopter Company Model R66 Helicopter; Flight Control System Annunciation of Control","toc_doc":"Skyryse, Robinson Helicopter Company Model R66 Helicopter; Flight Control System Annunciation of Control","toc_subject":"Special Conditions","topics":["Aircraft","Aviation safety","Reporting and recordkeeping requirements"],"type":"Proposed Rule","volume":91}
