{"abstract":"This action proposes special conditions for the Safran Electric & Power S.A. (Safran) Model ENGINe<SUP>TM</SUP> US100A1 electric engines that operate using electrical technology installed on the aircraft for use as an aircraft engine. These engines have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards applicable to aircraft engines. The design feature is the use of an electric motor, motor controller, and high-voltage systems as the primary source of propulsion for an aircraft. 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/2024/03/20/2024-05101.html","cfr_references":[{"chapter":null,"citation_url":null,"part":33,"title":14}],"citation":"89 FR 19763","comment_url":"https://www.regulations.gov/commenton/FAA-2023-0587-0001","comments_close_on":"2024-04-19","correction_of":null,"corrections":[],"dates":"Send comments on or before April 19, 2024.","disposition_notes":null,"docket_ids":["Docket No. FAA-2023-0587","Notice No. 33-23-01-SC"],"dockets":[{"supporting_documents":[],"agency_name":"FAA","documents":[{"comment_count":6,"comment_start_date":"2024-03-20","updated_at":"2024-09-03T16:48:19.904-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2023-0587-0001","allow_late_comments":true,"id":"FAA-2023-0587-0001","comment_end_date":"2024-04-20","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"FAA-2023-0587","title":"Special Conditions:  Safran Electric & Power S.A.
