{"abstract":"This document proposes to supersede AD 82-07-03, which currently requires repetitively testing (pressure decay) JanAero Devices B-Series combustion heaters, Models B1500, B2030, B3040, and B4050, that are installed on aircraft, and overhauling any heater that does not pass one of these pressure decay tests. The proposed action would retain these pressure decay tests and possible heater overhaul; and would require repetitiveoperational testing of the combustion air pressure switch, and replacing any combustion pressure switch that does not pass one of these tests. Two occurrences of failure of the affected heaters prompted the proposed action. In one case, an explosion resulted and the baggage compartment door was blown off the airplane. In the other case, a fire occurred in the baggage compartment while the airplane was in flight. The actions specified by the proposed AD are intended to prevent an airplane fire or explosion caused by failure of the heater combustion tube assembly or combustion air pressure switch.","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/1996/03/15/96-6192.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"61 FR 10703","comment_url":null,"comments_close_on":"1996-05-17","correction_of":null,"corrections":[],"dates":"Comments must be received on or before May 17, 1996.","disposition_notes":null,"docket_ids":["Docket No. 95-CE-83-AD"],"dockets":[],"document_number":"96-6192","effective_on":null,"end_page":10706,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1996/03/15/96-6192/airworthiness-directives-janaero-devices-formerly-janitrol-candd-fl-aerospace-and-midland-ross","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/96-6192?publication_date=1996-03-15","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1996-03-15/96-6192/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":171,"last_updated":"2026-08-24 04:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1996-03-15/pdf/96-6192.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1996-03-15","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1996/03/15/96-6192.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T01:30:40Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":10703,"subtype":null,"title":"Airworthiness Directives; JanAero Devices (formerly Janitrol, C&D, FL Aerospace, and Midland-Ross Corporation) B series combustion heaters, Models B1500, B2030, B3040, and B4050","toc_doc":null,"toc_subject":null,"topics":[],"type":"Proposed Rule","volume":61}
