{"abstract":"We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires removing affected PBE units. This AD was prompted by reports of potentially defective potassium superoxide canisters used in PBE units, which could result in an exothermic reaction and ignition. We are issuing this AD to prevent PBE units from igniting, which could result in a fire and possible injury to the flightcrew or other persons.","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/2011/01/05/2010-32994.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"76 FR 435","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective February 9, 2011.","disposition_notes":null,"docket_ids":["Docket No. FAA-2010-0797","Directorate Identifier 2010-NM-141-AD","Amendment 39-16562","AD 2011-01-09"],"dockets":[],"document_number":"2010-32994","effective_on":"2011-02-09","end_page":437,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2011/01/05/2010-32994.xml","html_url":"https://www.federalregister.gov/documents/2011/01/05/2010-32994/airworthiness-directives-be-aerospace-protective-breathing-equipment-pbe-part-number-119003-11","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2010-32994?publication_date=2011-01-05","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2011-01-05/2010-32994/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":1359,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2011-01-05/pdf/2010-32994.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2011-01-05","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2011/01/05/2010-32994.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":{"checked_regulationsdotgov_at":"2011-01-25T08:06:12Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":435,"subtype":null,"title":"Airworthiness Directives; B/E Aerospace Protective Breathing Equipment (PBE) Part Number 119003-11 Installed on Various Transport Airplanes","toc_doc":"B/E Aerospace Protective Breathing Equipment (PBE) Part Number 11900311 Installed on Various Transport Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":76}
