{"abstract":"This document proposes to supersede Airworthiness Directive (AD) 80-04-08, which currently requires inspecting (one-time) the fuel line and map light switch in the left hand forward door post for chafing or arcing and repairing any damage found on certain Cessna Aircraft Company (Cessna) Model 172N, R172K, F172N, and FR172K airplanes. AD 80-04-08 also required providing at least a 0.50-inch clearance between the map light switch and the fuel line; and installing a switch cover (insulator) over the map light switch. The FAA has determined that chafing between the map light switch and the fuel line could continue to develop over the life of the affected airplanes. The proposed AD would extend the inspections and installation of the switch cover requirement to certain 172N, 172P, R172K, 172RG, F172N, F172P, FR172J, and FR172K series airplanes. The proposed AD would also require replacement of the fuel line, if damaged; and would make the switch cover inspection and replacement repetitive. The actions specified by the proposed AD are intended to detect and correct any chafing between the map light switch and the bordering fuel line, which could result in a fuel leak and an in-flight fire.","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/2001/01/08/01-343.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"66 FR 1273","comment_url":null,"comments_close_on":"2001-02-12","correction_of":null,"corrections":[],"dates":"The Federal Aviation Administration (FAA) must receive any comments on this proposed rule by February 12, 2001.","disposition_notes":null,"docket_ids":["Docket No. 2000-CE-26-AD"],"dockets":[],"document_number":"01-343","effective_on":null,"end_page":1276,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2001/01/08/01-343.xml","html_url":"https://www.federalregister.gov/documents/2001/01/08/01-343/airworthiness-directives-cessna-aircraft-company-models-172n-172p-r172k-172rg-f172n-f172p-fr172j-and","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/01-343?publication_date=2001-01-08","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2001-01-08/01-343/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":683,"last_updated":"2026-08-24 14:15:12 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2001-01-08/pdf/01-343.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2001-01-08","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2001/01/08/01-343.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":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":1273,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company Models 172N, 172P, R172K, 172RG, F172N, F172P, FR172J, and FR172K Airplanes","toc_doc":"Cessna","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":66}
