{"abstract":"These amendments upgrade the fire safety standards for cargo or baggage compartments in certain transport category airplanes by eliminating Class D compartments as an option for future type certification. Compartments that can no longer be designated as Class D must meet the standards for Class C or Class E compartments, as applicable. The Class D compartments in certain transport category airplanes manufactured under existing type certificates and used in passenger service must meet the fire or smoke detection and fire suppression standards for Class C compartments by early 2001 for use in air carrier, or most other commercial service. The Class D compartments in certain transport category airplanes manufactured under existing type certificates and used only for the carriage of cargo must also meet such standards or the corresponding standards for Class E compartments by that date for such service. These improved standards are adopted to increase protection from possible in-flight fires. The FAA also requests additional comments concerning specific issues related to transport category airplanes used by part 135 operators. Those issues are enumerated under the section entitled Request for Comments.","action":"Final rule; request for comments.","agencies":[{"raw_name":"Revised Standards for Cargo or Baggage Compartments in Transport"},{"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/1998/02/17/98-3838.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"25","title":14},{"chapter":null,"citation_url":null,"part":"121","title":14}],"citation":"63 FR 8032","comment_url":null,"comments_close_on":"1998-06-17","correction_of":null,"corrections":[],"dates":"Effective March 19, 1998.
