{"abstract":"This amendment adopts a new airworthiness directive (AD) that is applicable to certain Gulfstream Model G-V series airplanes. This action requires an initial inspection of the electrical connections for the fire extinguisher bottles; an inspection after any subsequent maintenance affecting the fire extinguisher bottles; corrective action, if necessary; and reporting of the results of the inspection to the Federal Aviation Administration (FAA). This action is prompted by a report indicating that the electrical connections for the fire extinguisher bottle squibs had been improperly installed either during manufacturing or during subsequent maintenance. This action is necessary to prevent fire extinguishing agent from being discharged into the wrong location, which could result in failure to extinguish an in-flight fire on an affected engine and jeopardize operation of the opposite engine. This action is intended to address the identified unsafe condition.","action":"Final rule; request for comments.","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/2001/10/22/01-26473.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"66 FR 53337","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective November 6, 2001.","disposition_notes":null,"docket_ids":["Docket No. 2001-NM-305-AD","Amendment 39-12477","AD 2001-21-06"],"dockets":[],"document_number":"01-26473","effective_on":"2001-11-06","end_page":53339,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2001/10/22/01-26473.xml","html_url":"https://www.federalregister.gov/documents/2001/10/22/01-26473/airworthiness-directives-gulfstream-model-g-v-series-airplanes","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/01-26473?publication_date=2001-10-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2001-10-22/01-26473/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":23,"last_updated":"2026-08-23 18:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2001-10-22/pdf/01-26473.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2001-10-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2001/10/22/01-26473.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":53337,"subtype":null,"title":"Airworthiness Directives; Gulfstream Model G-V Series Airplanes","toc_doc":"Gulfstream","toc_subject":"Airworthiness directives:","topics":["Air transportation","Aircraft","Aviation safety","Incorporation by reference","Safety"],"type":"Rule","volume":66}
