{"abstract":"We are adopting a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/ 350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1- H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as wear and cracks on the stabilizer-trim attachment and structural components. We are issuing this AD to require actions to address the unsafe condition on these products.","action":"Final rule; request for comments.","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/2016/11/04/2016-26431.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"81 FR 76845","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective November 4, 2016.","disposition_notes":null,"docket_ids":["Docket No. FAA-2016-9356","Directorate Identifier 2016-CE-033-AD","Amendment 39-18701","AD 2016-22-12"],"dockets":[{"supporting_documents":[{"title":"PC-6 SB 53-003 R1","document_id":"FAA-2016-9356-0003"},{"title":"2016-CE-033-AD Foreign AD","document_id":"FAA-2016-9356-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2016-11-04","updated_at":"2023-03-01T13:25:58.246-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2016-9356-0001","allow_late_comments":null,"id":"FAA-2016-9356-0001","comment_end_date":"2016-12-20","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2016-9356","title":"Pilatus PC-6 rear fuselage stabilizer trim attachment components"}],"document_number":"2016-26431","effective_on":"2016-11-04","end_page":76848,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/11/04/2016-26431.xml","html_url":"https://www.federalregister.gov/documents/2016/11/04/2016-26431/airworthiness-directives-pilatus-aircraft-ltd-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-26431?publication_date=2016-11-04","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-11-04/2016-26431/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":169,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-11-04/pdf/2016-26431.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-26431.pdf?1478177128","publication_date":"2016-11-04","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/11/04/2016-26431.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202410","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202410&RIN=2120-AA64&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["2120-AA64"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"PC-6 SB 53-003 R1","document_id":"FAA-2016-9356-0003"},{"title":"2016-CE-033-AD Foreign AD","document_id":"FAA-2016-9356-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2016-9356","supporting_documents_count":2,"docket_id":"FAA-2016-9356","document_id":"FAA-2016-9356-0001","regulation_id_number":"2120-AA64","title":"Pilatus PC-6 rear fuselage stabilizer trim attachment components","checked_regulationsdotgov_at":"2024-11-08T11:00:15Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":76845,"subtype":null,"title":"Airworthiness Directives; Pilatus Aircraft Ltd.
