{"abstract":"We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 050 airplanes, and Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by reports of loose nuts on contactors in the electrical power center (EPC), and in some cases, burned contactors. This proposed AD would require inspecting and, if necessary, adjusting, the torque values of nuts on circuit breakers, contactors and terminal blocks of the EPC and battery relay panel. This proposed AD would also require inspecting to determine if certain parts are installed, and installing the parts if necessary. We are proposing this AD to detect and correct loose nuts, which could result in arcing and potentially an onboard fire, possibly resulting in damage to the airplane and injury to occupants or maintenance personnel.","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/2012/03/21/2012-6804.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"77 FR 16486","comment_url":null,"comments_close_on":"2012-05-07","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by May 7, 2012.","disposition_notes":null,"docket_ids":["Docket No. FAA-2012-0270","Directorate Identifier 2011-NM-113-AD"],"dockets":[],"document_number":"2012-6804","effective_on":null,"end_page":16488,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/03/21/2012-6804.xml","html_url":"https://www.federalregister.gov/documents/2012/03/21/2012-6804/airworthiness-directives-fokker-services-bv-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-6804?publication_date=2012-03-21","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-03-21/2012-6804/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":39,"last_updated":"2026-04-04 10:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-03-21/pdf/2012-6804.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-06804.pdf?1332247734","publication_date":"2012-03-21","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/03/21/2012-6804.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":{"supporting_documents":[{"title":"U.S. DOT/FAA - See Attachment","document_id":"FAA-2012-0270-0005"},{"title":"U.S. DOT - See Attachments","document_id":"FAA-2012-0270-0004"},{"title":"U.S. DOT/FAA - See Attachments","document_id":"FAA-2012-0270-0002"}],"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-2012-0270","supporting_documents_count":3,"docket_id":"FAA-2012-0270","document_id":"FAA-2012-0270-0001","regulation_id_number":"2120-AA64","title":"2011-NM-113-AD Airworthiness Directive; Fokker Services B.V.
