{"abstract":"The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.","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/2025/05/07/2025-07929.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"90 FR 19264","comment_url":null,"comments_close_on":"2025-06-23","correction_of":null,"corrections":[],"dates":"The FAA must receive comments on this proposed AD by June 23, 2025.","disposition_notes":null,"docket_ids":["Docket No. FAA-2025-0751","Project Identifier MCAI-2024-00305-T"],"dockets":[{"supporting_documents":[{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-0751-0007"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2025-0751-0002"}],"agency_name":"FAA","documents":[{"comment_count":3,"comment_start_date":"2025-05-07","updated_at":"2025-06-24T01:56:05.636-04:00","comment_url":"https://www.regulations.gov/commenton/FAA-2025-0751-0001","allow_late_comments":false,"id":"FAA-2025-0751-0001","comment_end_date":"2025-06-24","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":2,"id":"FAA-2025-0751","title":"MCAI-2024-00305-T; Bombardier Inc.
