{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. This proposed AD would require you to inspect any MC01-3A I.C. 9 or MC01-3A I.C. 10 main electrical power junction box circuit breakers for correct amperage (amp) (a correct 40- amp circuit breaker) and replace any incorrect amp circuit breaker with the correct 40-amp circuit breaker. This proposed AD results from several reports of circuit breakers that are not the correct 40-amp circuit breaker installed in the MC01-3A main electrical power junction box. We are issuing this proposed AD to replace any incorrect circuit breaker installed in the MC01-3A I.C. 9 or MC01-3A I.C. 10 main electrical power junction box, which could result in premature tripping of the power junction box main feeder circuit breakers and could lead to partial or complete loss of all electrical power on the airplane. This failure could lead to the loss of all navigation and communication equipment and lighting in the cockpit.","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/2005/03/17/05-5294.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"70 FR 12978","comment_url":null,"comments_close_on":"2005-05-16","correction_of":null,"corrections":[],"dates":"We must receive any comments on this proposed AD by May 16, 2005.","disposition_notes":null,"docket_ids":["Docket No. FAA-2005-20438","Directorate Identifier 2005-CE-03-AD"],"dockets":[],"document_number":"05-5294","effective_on":null,"end_page":12981,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2005/03/17/05-5294.xml","html_url":"https://www.federalregister.gov/documents/2005/03/17/05-5294/airworthiness-directives-cessna-aircraft-company-models-172r-172s-182t-t182t-206h-and-t206h","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/05-5294?publication_date=2005-03-17","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2005-03-17/05-5294/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":118,"last_updated":"2026-10-23 10:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2005-03-17/pdf/05-5294.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2005-03-17","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2005/03/17/05-5294.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":"2014-11-26T22:20:50Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":12978,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company Models 172R, 172S, 182T, T182T, 206H, and T206H Airplanes","toc_doc":"Cessna Aircraft Co.","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":70}
