{"abstract":"We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-46-500TP airplanes. This AD was prompted by a report of the wing upper skin joints being manufactured without sealant, which allows water to enter and stay in sealed, bonded stringers. This AD requires inspecting the upper wing surface for sealant; inspecting the wing stringers for water intrusion; inspecting for deformation and corrosion if evidence of water intrusion exists; and taking corrective actions as necessary. 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/2016/01/13/2015-33170.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"81 FR 1502","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective February 17, 2016.","disposition_notes":null,"docket_ids":["Docket No. FAA-2015-4213","Directorate Identifier 2015-CE-022-AD","Amendment 39-18359","AD 2016-01-01"],"dockets":[],"document_number":"2015-33170","effective_on":"2016-02-17","end_page":1504,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/01/13/2015-33170.xml","html_url":"https://www.federalregister.gov/documents/2016/01/13/2015-33170/airworthiness-directives-piper-aircraft-inc-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2015-33170?publication_date=2016-01-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-01-13/2015-33170/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":99,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-01-13/pdf/2015-33170.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2015-33170.pdf?1452606326","publication_date":"2016-01-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/01/13/2015-33170.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 - Regulatory Evaluation","document_id":"FAA-2015-4213-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2015-4213","supporting_documents_count":1,"docket_id":"FAA-2015-4213","regulation_id_number":null,"title":"Piper PA-46-500TP upper wing sealant","checked_regulationsdotgov_at":"2016-02-02T06:00:14Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":1502,"subtype":null,"title":"Airworthiness Directives; Piper Aircraft, Inc.
