{"abstract":"This document proposes to supersede Airworthiness Directive (AD) 2000-23-01, which applies to all Cessna Aircraft Company (Cessna) Model 402C airplanes. AD 2000-23-01 currently requires repetitive inspections of the forward, aft, and auxiliary wing spars for cracks, and repair or replacement as necessary. Cessna has performed fatigue and crack growth analyses of the wings of these airplanes, and the Federal Aviation Administration (FAA) has evaluated this information and determined that a wing spar modification and inspections are necessary on the Model 414A airplanes as well as the Model 402C airplanes. This proposed AD would require you to inspect the wing spar caps for fatigue cracks with any necessary repair or replacement and to incorporate a spar strap modification on each wing spar. The actions specified by this proposed AD are intended to prevent wing spar cap failure due to undetected fatigue cracks. Such failure could result in loss of a wing with consequent loss of airplane control.","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/2003/05/15/03-12111.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"68 FR 26244","comment_url":null,"comments_close_on":"2003-08-08","correction_of":null,"corrections":[],"dates":"The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before August 8, 2003.","disposition_notes":null,"docket_ids":["Docket No. 2002-CE-57-AD"],"dockets":[],"document_number":"03-12111","effective_on":null,"end_page":26247,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2003/05/15/03-12111.xml","html_url":"https://www.federalregister.gov/documents/2003/05/15/03-12111/airworthiness-directives-cessna-aircraft-company-models-402c-and-414a-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/03-12111?publication_date=2003-05-15","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2003-05-15/03-12111/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":56,"last_updated":"2026-10-24 04:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2003-05-15/pdf/03-12111.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2003-05-15","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2003/05/15/03-12111.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":26244,"subtype":null,"title":"Airworthiness Directives; Cessna Aircraft Company Models 402C and 414A Airplanes","toc_doc":"Cessna","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":68}
