{"abstract":"We propose to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, PW127H, and PW127M turboprop engines. This proposed AD was prompted by reports of fuel leaks at the interface between the fuel manifold and the fuel nozzle that resulted in engine fire. This proposed AD would require removal of the O-ring seal from the fuel manifold fitting. We are proposing this AD to prevent in-flight fuel leakage, which could lead to engine fire, damage to the engine, and damage to the airplane.","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/2014/03/21/2014-06163.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"79 FR 15707","comment_url":"https://www.regulations.gov/commenton/FAA-2013-1059-0001","comments_close_on":"2014-05-20","correction_of":null,"corrections":[],"dates":"We must receive comments on this proposed AD by May 20, 2014.","disposition_notes":null,"docket_ids":["Docket No. FAA-2013-1059","Directorate Identifier 2013-NE-36-AD"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2013-1059-0008"},{"title":"U.S. DOT/FAA - Various Supplemental AD Documents","document_id":"FAA-2013-1059-0007"},{"title":"U.S. DOT/FAA - Various Supplemental AD Documents","document_id":"FAA-2013-1059-0004"}],"agency_name":"FAA","documents":[{"comment_count":1,"comment_start_date":"2014-03-21","updated_at":"2024-11-08T15:38:35.296-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2013-1059-0001","allow_late_comments":true,"id":"FAA-2013-1059-0001","comment_end_date":"2014-05-21","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":3,"id":"FAA-2013-1059","title":"2013-NE-36-AD\nPratt & Whitney Canada Corp.
