{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AB139, AW139, AB412, and AB412 EP helicopters. This AD was prompted by failure of an Emergency Flotation System (EFS) float compartment to inflate during maintenance of the EFS. This AD requires inspecting certain EFSs and depending on the results, marking certain parts or removing certain parts from service, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.","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/2021/10/18/2021-22470.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"86 FR 57567","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0608-0002","comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective November 22, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0608","Project Identifier 2019-SW-119-AD","Amendment 39-21750","AD 2021-20-12"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2021-0608-0003"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2021-10-18","updated_at":"2024-11-06T20:51:29.773-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0608-0002","allow_late_comments":true,"id":"FAA-2021-0608-0002","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2021-0608","title":"Leonardo S.p.a.
