{"abstract":"This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This proposal would require a one-time general visual inspection of the electrical wiring of the right side of the cockpit to determine if the electrical wiring is chafing against the observer station and to detect damaged wires; and corrective actions, if necessary. This action is necessary to prevent chafing and damage to electrical wires of the cockpit and consequent electrical arcing due to wires that were routed improperly during production of the airplane, which could result in fire and smoke in the airplane. This action is intended to address the identified unsafe condition.","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/2001/02/20/01-4050.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"66 FR 10858","comment_url":null,"comments_close_on":"2001-04-06","correction_of":null,"corrections":[],"dates":"Comments must be received by April 6, 2001.","disposition_notes":null,"docket_ids":["Docket No. 2000-NM-185-AD"],"dockets":[],"document_number":"01-4050","effective_on":null,"end_page":10860,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2001/02/20/01-4050.xml","html_url":"https://www.federalregister.gov/documents/2001/02/20/01-4050/airworthiness-directives-mcdonnell-douglas-model-md-11-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/01-4050?publication_date=2001-02-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2001-02-20/01-4050/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":4,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2001-02-20/pdf/01-4050.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2001-02-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2001/02/20/01-4050.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":10858,"subtype":null,"title":"Airworthiness Directives; McDonnell Douglas Model MD-11 Series Airplanes","toc_doc":"McDonnell Douglas","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":66}
