{"abstract":"We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This proposed AD was prompted by a report that during removal of left-hand (LH) gear rib 5, four failed fasteners were discovered. This proposed AD would require a one-time ultrasonic inspection of the LH and right-hand (RH) wing rib 5-to-rear spar attachments for cracked or failed fasteners, and if necessary, a detailed inspection of the gear rib 5 and spar web for cracks and damage, a rotating probe test of the gear rib and spar web bolt holes for cracks and damage, reaming the gear rib and the spar web bolt holes, and replacement of cracked or failed fasteners. We are 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/2018/08/09/2018-16733.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"83 FR 39377","comment_url":"http://www.regulations.gov/commenton/FAA-2018-0705-0001","comments_close_on":"2018-09-24","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by September 24, 2018.","disposition_notes":null,"docket_ids":["Docket No. FAA-2018-0705","Product Identifier 2018-NM-077-AD"],"dockets":[],"document_number":"2018-16733","effective_on":null,"end_page":39380,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2018/08/09/2018-16733.xml","html_url":"https://www.federalregister.gov/documents/2018/08/09/2018-16733/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2018-16733?publication_date=2018-08-09","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2018-08-09/2018-16733/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":101,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2018-08-09/pdf/2018-16733.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2018-16733.pdf?1533732316","publication_date":"2018-08-09","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2018/08/09/2018-16733.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":"Supporting AD Documents","document_id":"FAA-2018-0705-0005"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2018-0705-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2018-0705","supporting_documents_count":2,"docket_id":"FAA-2018-0705","regulation_id_number":"2120-AA64","title":"2018-NM-077-AD\nAirbus SAS Model A321‑111, ‑112, ‑131, ‑211, -212, -213, -231, and ‑232 airplanes","checked_regulationsdotgov_at":"2023-03-01T19:37:45Z"},"regulations_dot_gov_url":"http://www.regulations.gov/commenton/FAA-2018-0705-0001","significant":false,"signing_date":null,"start_page":39377,"subtype":null,"title":"Airworthiness Directives; Airbus SAS Airplanes","toc_doc":"Airbus SAS Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":83}
