{"abstract":"This document revises an earlier proposed airworthiness directive (AD), applicable to certain Boeing Model 737 series airplanes, that would have required inspections of certain bonded skin panels to detect delamination of the skin doublers (tear straps) from the skin panels; and follow-on corrective actions, if necessary. That proposal was prompted by reports that certain skin doublers were delaminated from their skin panels due to improper processing of certain skin panels. This new action would revise the proposed rule by referencing new service information that incorporates new inspection procedures and corrective actions, and recommends new compliance times. This new action also would remove airplanes from the applicability. The actions specified by this new proposed AD are intended to prevent skin doublers from delaminating from their skin panels, which could result in fatigue cracks in the skin doublers and skin panels, and consequent rapid decompression of the airplane.","action":"Supplemental notice of proposed rulemaking; reopening of comment period.","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/2000/08/10/00-20248.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"65 FR 48937","comment_url":null,"comments_close_on":"2000-09-05","correction_of":null,"corrections":[],"dates":"Comments must be received by September 5, 2000.","disposition_notes":null,"docket_ids":["Docket No. 98-NM-11-AD"],"dockets":[],"document_number":"00-20248","effective_on":null,"end_page":48941,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2000/08/10/00-20248.xml","html_url":"https://www.federalregister.gov/documents/2000/08/10/00-20248/airworthiness-directives-boeing-model-737-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/00-20248?publication_date=2000-08-10","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2000-08-10/00-20248/mods.xml","not_received_for_publication":null,"page_length":5,"page_views":{"count":169,"last_updated":"2026-04-04 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2000-08-10/pdf/00-20248.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2000-08-10","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2000/08/10/00-20248.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":48937,"subtype":null,"title":"Airworthiness Directives; Boeing Model 737 Series Airplanes","toc_doc":"Boeing","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":65}
