{"abstract":"The FAA proposes to supersede Airworthiness Directive (AD) 2025-11-02, which applies to certain Airbus SAS Model A319-151N, -153N, -171N, and -173N airplanes; A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; A321-251N, -251NX, -252N, -252NX, -253N, -253NX, - 253NY, -271N, -271NX, -272N, and -272NX airplanes. AD 2025-11-02 requires revising the existing airplane flight manual (AFM) by providing instructions to address dual loss of radio management panel (RMP) data synchronization. Since the FAA issued AD 2025-11-02, a software modification for the digital radio and audio integrating management system (DRAIMS) has been developed to address the unsafe condition. This proposed AD would continue to require the actions in AD 2025-11-02 and would require modification of the DRAIMS and add Model A321-271NY airplanes to the applicability. 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/2026/04/13/2026-07052.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"91 FR 18792","comment_url":"http://www.regulations.gov/commenton/FAA-2026-3481-0001","comments_close_on":"2026-05-28","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by May 28, 2026.","disposition_notes":null,"docket_ids":["Docket No. FAA-2026-3481","Project Identifier MCAI-2025-00970-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2026-3481-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2026-04-13","updated_at":"2026-04-13T09:56:14.108-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2026-3481-0001","allow_late_comments":false,"id":"FAA-2026-3481-0001","comment_end_date":"2026-05-29","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":1,"id":"FAA-2026-3481","title":"MCAI-2025-00970-T;
