{"abstract":"The FAA is adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This AD was prompted by a report that for airplanes converted from passenger to cargo configuration using certain supplemental type certificates, no height limitation for the cargo, when loaded in the cargo compartment, is defined, and that as a consequence, cargo might be loaded up to the ceiling of the cargo compartment. This AD requires modification of the cargo compartment and implementation of updated cargo loading procedures. The FAA is issuing this AD to address 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/2024/12/09/2024-28789.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"89 FR 97477","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective January 13, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2024-2129","Project Identifier MCAI-2024-00066-T","Amendment 39-22889","AD 2024-23-10"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-2129-0005"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-2129-0002"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2024-12-09","updated_at":"2024-12-09T09:56:39.398-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2024-2129-0004","allow_late_comments":false,"id":"FAA-2024-2129-0004","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2024-2129","title":"MCAI-2024-00066-T; ATR – GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes; no height limitation for the cargo is defined."}],"document_number":"2024-28789","effective_on":"2025-01-13","end_page":97480,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2024/12/09/2024-28789.xml","html_url":"https://www.federalregister.gov/documents/2024/12/09/2024-28789/airworthiness-directives-atr-gie-avions-de-transport-rgional-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2024-28789?publication_date=2024-12-09","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2024-12-09/2024-28789/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":103,"last_updated":"2026-04-04 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2024-12-09/pdf/2024-28789.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2024-28789.pdf?1733492724","publication_date":"2024-12-09","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2024/12/09/2024-28789.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-2024-2129-0005"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2024-2129-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"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-2024-2129","supporting_documents_count":2,"docket_id":"FAA-2024-2129","document_id":"FAA-2024-2129-0004","regulation_id_number":"2120-AA64","title":"MCAI-2024-00066-T; ATR – GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes; no height limitation for the cargo is defined.","checked_regulationsdotgov_at":"2024-12-10T13:00:17Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":97477,"subtype":null,"title":"Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes","toc_doc":"ATRGIE Avions de Transport Regional Airplanes","toc_subject":"Airworthiness Directives","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":89}
