{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; Model A319 series airplanes; Model A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, - 251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This proposed AD was prompted by reports of a certain nose landing gear (NLG) sliding tube having widespread overheat damage and multiple cracks on the base metal during shop visits. This proposed AD would require a special detailed inspection (SDI) of the affected NLG sliding tube and replacement, as applicable. This proposed AD would also prohibit the installation of affected parts. 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/2026/08/13/2026-16566.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 52266","comment_url":null,"comments_close_on":"2026-09-28","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by September 28, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-8779","Project Identifier MCAI-2025-01748-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-8779-0002"}],"agency_name":"FAA","documents":[{"comment_count":2,"comment_start_date":"2026-08-13","updated_at":"2026-09-29T00:09:30.862-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-8779-0001","allow_late_comments":false,"id":"FAA-2026-8779-0001","comment_end_date":"2026-09-29","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2026-8779","title":"MCAI-2025-01748-T; Airbus SAS Model A318, A319, A320, and A321 airplanes; nose landing gear sliding tube"}],"document_number":"2026-16566","effective_on":null,"end_page":52268,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/08/13/2026-16566.xml","html_url":"https://www.federalregister.gov/documents/2026/08/13/2026-16566/airworthiness-directives-airbus-sas-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-16566?publication_date=2026-08-13","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-08-13/2026-16566/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":171,"last_updated":"2026-10-24 06:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-08-13/pdf/2026-16566.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-16566.pdf?1786538720","publication_date":"2026-08-13","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/08/13/2026-16566.txt","regulation_id_number_info":{"2120-AA64":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&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-2026-8779-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":2,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2026-8779","supporting_documents_count":1,"docket_id":"FAA-2026-8779","document_id":"FAA-2026-8779-0001","regulation_id_number":"2120-AA64","title":"MCAI-2025-01748-T; Airbus SAS Model A318, A319, A320, and A321 airplanes; nose landing gear sliding tube","checked_regulationsdotgov_at":"2026-09-29T08:55:03Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":52266,"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":91}
