{"abstract":"This document proposes the supersedure of an existing airworthiness directive (AD), applicable to all Raytheon Model DH.125- 1A, -3A, and -400A series airplanes, that currently requires a one-time inspection to detect scoring of the upper fuselage skin around the periphery of the cockpit canopy blister interface, and repair, if necessary. This action would expand the applicability of the existing AD to include additional airplanes, and would require that the actions be accomplished in accordance with revised service information for the newly added airplanes. This AD is prompted by additional reports indicating that scoring has been detected on the upper fuselage skin around the periphery of the cockpit canopy blister interface. The actions specified by the proposed AD are intended to detect and correct scoring of the upper fuselage skin around the periphery of the cockpit canopy blister interface, which could result in reduced structural integrity of the fuselage, and consequent cabin depressurization.","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/2000/06/16/00-15310.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"65 FR 37723","comment_url":null,"comments_close_on":"2000-07-31","correction_of":null,"corrections":[],"dates":"Comments must be received by July 31, 2000.","disposition_notes":null,"docket_ids":["Docket No. 99-NM-345-AD"],"dockets":[],"document_number":"00-15310","effective_on":null,"end_page":37725,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2000/06/16/00-15310.xml","html_url":"https://www.federalregister.gov/documents/2000/06/16/00-15310/airworthiness-directives-raytheon-model-bh125-dh125-and-hs125-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/00-15310?publication_date=2000-06-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2000-06-16/00-15310/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":6,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2000-06-16/pdf/00-15310.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2000-06-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2000/06/16/00-15310.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":37723,"subtype":null,"title":"Airworthiness Directives; Raytheon Model BH.125, DH.125, and HS.125 Series Airplanes","toc_doc":"Raytheon","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Safety"],"type":"Proposed Rule","volume":65}
