{"abstract":"We are superseding Airworthiness Directive (AD) 99-01-05 R1, which applied to certain aircraft equipped with wing lift struts. AD 99-01-05 R1 required repetitively inspecting the wing lift struts for corrosion; repetitively inspecting the wing lift strut forks for cracks; replacing any corroded wing lift strut; replacing any cracked wing lift strut fork; and repetitively replacing the wing lift strut forks at a specified time for certain airplanes. This new AD retains all requirements of AD 99-01-05R1 and adds additional airplane models to the Applicability section. This AD was prompted by a report that additional Piper Aircraft, Inc. model airplanes should be added to the Applicability section. We are issuing this AD to correct 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/2015/04/29/2015-08732.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"80 FR 23699","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective June 3, 2015.","disposition_notes":null,"docket_ids":["Docket No. FAA-2014-1083","Directorate Identifier 2014-CE-036-AD","Amendment 39-18140","AD 2015-08-04"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Various Supplemental AD Documents","document_id":"FAA-2014-1083-0006"},{"title":"U.S. DOT/FAA - Regulatory Evaluation","document_id":"FAA-2014-1083-0002"}],"agency_name":null,"documents":[{"comment_count":0,"comment_start_date":"2015-04-29","updated_at":"2023-03-01T15:51:27.609-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2014-1083-0005","allow_late_comments":null,"id":"FAA-2014-1083-0005","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2014-1083","title":"2014-CE-036-AD"}],"document_number":"2015-08732","effective_on":"2015-06-03","end_page":23707,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2015/04/29/2015-08732.xml","html_url":"https://www.federalregister.gov/documents/2015/04/29/2015-08732/airworthiness-directives-various-aircraft-equipped-with-wing-lift-struts","images":{"ER29AP15.000":{"large":"https://img.federalregister.gov/ER29AP15.000/ER29AP15.000_large.png","medium":"https://img.federalregister.gov/ER29AP15.000/ER29AP15.000_medium.png","original_size":"https://img.federalregister.gov/ER29AP15.000/ER29AP15.000_original_size.png"}},"images_metadata":{"ER29AP15.000":{"large":{"identifier":"ER29AP15.000","content_type":"image/png","size":29423,"width":823,"sha":"1d2c38674aa44e31eb40c1699f2922a4","url":"https://img.federalregister.gov/ER29AP15.000/ER29AP15.000_large.png","height":478},"medium":{"identifier":"ER29AP15.000","content_type":"image/png","size":11978,"width":479,"sha":"901db6ec4a9193fd7b2368d04f9d73ff","url":"https://img.federalregister.gov/ER29AP15.000/ER29AP15.000_medium.png","height":278},"original_size":{"identifier":"ER29AP15.000","content_type":"image/png","size":55753,"width":3618,"sha":"6fa7d00c8e1c9efc71ee0200e28b3470","url":"https://img.federalregister.gov/ER29AP15.000/ER29AP15.000_original_size.png","height":2101}}},"json_url":"https://www.federalregister.gov/api/v1/documents/2015-08732?publication_date=2015-04-29","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2015-04-29/2015-08732/mods.xml","not_received_for_publication":null,"page_length":9,"page_views":{"count":5367,"last_updated":"2026-08-23 20:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2015-04-29/pdf/2015-08732.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2015-08732.pdf?1430225115","publication_date":"2015-04-29","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2015/04/29/2015-08732.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 - Various Supplemental AD Documents","document_id":"FAA-2014-1083-0006"},{"title":"U.S. DOT/FAA - Regulatory Evaluation","document_id":"FAA-2014-1083-0002"}],"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-2014-1083","supporting_documents_count":2,"docket_id":"FAA-2014-1083","document_id":"FAA-2014-1083-0005","regulation_id_number":null,"title":"2014-CE-036-AD","checked_regulationsdotgov_at":"2023-03-01T20:51:26Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":23699,"subtype":null,"title":"Airworthiness Directives;
