{"abstract":"We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports of cracks caused by corrosion of the edge of the bore of the spot face and corrosion of the lug bore of certain side-strut support fitting lugs. This AD requires repetitive detailed inspections of the left and right side-strut support fitting lugs with bushings installed for any corrosion, any crack, or any severed lug; repetitive detailed and high frequency eddy current (HFEC) inspections of the left and right side-strut support fitting lugs with bushings removed for any corrosion or any crack; and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.","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/2019/06/06/2019-11790.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"84 FR 26331","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective July 11, 2019.","disposition_notes":null,"docket_ids":["Docket No. FAA-2018-1004","Product Identifier 2018-NM-106-AD","Amendment 39-19642","AD 2019-10-03"],"dockets":[{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2018-1004-0004"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2019-06-06","updated_at":"2023-03-01T15:46:06.940-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2018-1004-0005","allow_late_comments":null,"id":"FAA-2018-1004-0005","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"FAA-2018-1004","title":"2018-NM-106-AD\nThe Boeing Company Model 737‑100, ‑200, ‑200C, ‑300, ‑400, and ‑500 series airplanes"}],"document_number":"2019-11790","effective_on":"2019-07-11","end_page":26334,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/06/06/2019-11790.xml","html_url":"https://www.federalregister.gov/documents/2019/06/06/2019-11790/airworthiness-directives-the-boeing-company-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-11790?publication_date=2019-06-06","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-06-06/2019-11790/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":328,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-06-06/pdf/2019-11790.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-11790.pdf?1559738719","publication_date":"2019-06-06","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/06/06/2019-11790.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":{"supporting_documents":[{"title":"Supporting AD Documents","document_id":"FAA-2018-1004-0004"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2120-AA64/airworthiness-directives","title":"Airworthiness Directives"},"comments_count":0,"agency_id":"FAA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FAA-2018-1004","supporting_documents_count":1,"docket_id":"FAA-2018-1004","document_id":"FAA-2018-1004-0005","regulation_id_number":"2120-AA64","title":"2018-NM-106-AD\nThe Boeing Company Model 737‑100, ‑200, ‑200C, ‑300, ‑400, and ‑500 series airplanes","checked_regulationsdotgov_at":"2023-03-01T20:46:06Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":26331,"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":84}
