{"abstract":"The FAA proposes to supersede Airworthiness Directive (AD) 64- 09-03, which applies to all de Havilland (type certificate now held by Viking Air Limited) Model DHC-2 \"Beaver\" airplanes. AD 64-09-03 requires inspecting the aileron mass balance weight arms for cracks and corrosion and replacing any damaged part. Since the FAA issued AD 64- 09-03, Transport Canada superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This proposed AD would require establishing a corrosion prevention and control program to identify and correct corrosion. This proposed AD would also require completing all of the initial tasks identified in the program and reporting corrosion findings to Viking. The proposed corrosion prevention and control program would include the inspection of the aileron balance weight arms required by AD 64-09-03. The FAA is proposing this AD to address the unsafe condition on these products.","action":"Notice of proposed rulemaking (NPRM).","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/2022/02/08/2022-02548.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"87 FR 7065","comment_url":null,"comments_close_on":"2022-03-25","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by March 25, 2022.","disposition_notes":null,"docket_ids":["Docket No. FAA-2020-7071","Project Identifier 2019-CE-048-AD"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2022-0190-0033"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2022-0190-0029"}],"agency_name":"FAA","documents":[{"comment_count":23,"comment_start_date":"2022-02-08","updated_at":"2023-02-28T17:16:43.592-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2022-0190-0001","allow_late_comments":null,"id":"FAA-2022-0190-0001","comment_end_date":"2022-03-26","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2022-0190","title":"Viking DHC-2 Corrosion Control Program"}],"document_number":"2022-02548","effective_on":null,"end_page":7068,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2022/02/08/2022-02548.xml","html_url":"https://www.federalregister.gov/documents/2022/02/08/2022-02548/airworthiness-directives-viking-air-limited-type-certificate-previously-held-by-bombardier-inc-and","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2022-02548?publication_date=2022-02-08","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2022-02-08/2022-02548/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":511,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2022-02-08/pdf/2022-02548.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2022-02548.pdf?1644241520","publication_date":"2022-02-08","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2022/02/08/2022-02548.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":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2022-0190-0033"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2022-0190-0029"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":23,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2022-0190","supporting_documents_count":2,"docket_id":"FAA-2022-0190","document_id":"FAA-2022-0190-0001","regulation_id_number":"2120-AA64","title":"Viking DHC-2 Corrosion Control Program","checked_regulationsdotgov_at":"2023-02-28T22:16:42Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":7065,"subtype":null,"title":"Airworthiness Directives; Viking Air Limited (Type Certificate Previously Held by Bombardier Inc. and de Havilland, Inc.)
