{"abstract":"This action amends the flight data recorder regulations by adding language to allow certain Airbus airplanes to record certain data parameters using resolution and sampling requirements that differ slightly from the current regulation. This amendment is necessary because the Airbus airplanes are unable to record certain flight parameters under the existing criteria without undergoing unintended and expensive retrofit.","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/1999/08/24/99-21783.html","cfr_references":[{"chapter":null,"citation_url":null,"part":121,"title":14},{"chapter":null,"citation_url":null,"part":125,"title":14}],"citation":"64 FR 46117","comment_url":null,"comments_close_on":"1999-09-17","correction_of":null,"corrections":[],"dates":"This final rule is effective August 17, 1999.
