{"abstract":"We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This AD was prompted by reports indicating that a standard fuel tank access door was located where an impact-resistant access door was required, and stencils were missing from some impact-resistant access doors. This AD requires an inspection of the left- and right-hand wing fuel tank access doors to determine that impact-resistant access doors are installed in the correct locations, and to replace any door with an impact-resistant access door if necessary. This AD also requires an inspection for stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. This AD also requires revising the maintenance program to incorporate changes to the airworthiness limitations section. We are issuing this AD to prevent foreign object penetration of the fuel tank, which could cause a fuel leak near an ignition source (e.g., hot brakes), consequently leading to a fuel-fed fire.","action":"Final rule.","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/2013/10/31/2013-25132.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"78 FR 65193","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective December 5, 2013.","disposition_notes":null,"docket_ids":["Docket No. FAA-2013-0666","Directorate Identifier 2013-NM-060-AD","Amendment 39-17635","AD 2013-22-03"],"dockets":[],"document_number":"2013-25132","effective_on":"2013-12-05","end_page":65195,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2013/10/31/2013-25132.xml","html_url":"https://www.federalregister.gov/documents/2013/10/31/2013-25132/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2013-25132?publication_date=2013-10-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2013-10-31/2013-25132/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":48,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2013-10-31/pdf/2013-25132.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2013-25132.pdf?1383137367","publication_date":"2013-10-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2013/10/31/2013-25132.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":"2013-11-20T08:06:14Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":65193,"subtype":null,"title":"Airworthiness Directives; The Boeing Company Airplanes","toc_doc":"The Boeing Company Airplanes","toc_subject":"Airworthiness Directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":78}
