{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain Umlaut Engineering GmbH (previously P3 Engineering GmbH) HAFEX (Halon-free) hand-held P3HAFEX fire extinguishers (fire extinguishers). This proposed AD was prompted by reports of a quality control issue on certain fire extinguishers, where the spindle geometries of the fire extinguishers were found to be out of tolerance. This proposed AD would require removing affected fire extinguishers from service. 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/2021/10/08/2021-21952.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"39","title":14}],"citation":"86 FR 56232","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0843-0001","comments_close_on":"2021-11-22","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by November 22, 2021.","disposition_notes":null,"docket_ids":["Docket No. FAA-2021-0843","Project Identifier MCAI-2020-00256-Q"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2021-0843-0006"},{"title":"Supporting AD Document","document_id":"FAA-2021-0843-0004"}],"agency_name":"FAA","documents":[{"comment_count":2,"comment_start_date":"2021-10-08","updated_at":"2024-11-06T20:34:01.213-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2021-0843-0001","allow_late_comments":true,"id":"FAA-2021-0843-0001","comment_end_date":"2021-11-23","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2021-0843","title":"MCAI-2020-00256-Q  Hand held fire extenguisher"}],"document_number":"2021-21952","effective_on":null,"end_page":56234,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/10/08/2021-21952.xml","html_url":"https://www.federalregister.gov/documents/2021/10/08/2021-21952/airworthiness-directives-umlaut-engineering-gmbh-previously-p3-engineering-gmbh-hafex-halon-free","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-21952?publication_date=2021-10-08","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-10-08/2021-21952/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":258,"last_updated":"2026-08-26 02:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-10-08/pdf/2021-21952.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-21952.pdf?1633610723","publication_date":"2021-10-08","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/10/08/2021-21952.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":"Supporting AD Documents","document_id":"FAA-2021-0843-0006"},{"title":"Supporting AD Document","document_id":"FAA-2021-0843-0004"}],"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-2021-0843","supporting_documents_count":2,"docket_id":"FAA-2021-0843","document_id":"FAA-2021-0843-0001","regulation_id_number":"2120-AA64","title":"MCAI-2020-00256-Q  Hand held fire extenguisher","checked_regulationsdotgov_at":"2024-11-07T01:01:24Z"},"regulations_dot_gov_url":"https://www.regulations.gov/commenton/FAA-2021-0843-0001","significant":false,"signing_date":null,"start_page":56232,"subtype":null,"title":"Airworthiness Directives; Umlaut Engineering GmbH (Previously P3 Engineering GmbH) HAFEX (Halon-Free) Hand-Held Fire Extinguishers","toc_doc":"Umlaut Engineering GmbH (previously P3 Engineering GmbH) HAFEX (Halon-free) Hand-Held Fire Extinguishers","toc_subject":"Airworthiness Directives:\n","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Proposed Rule","volume":86}
