This legislation requires the Administrator of the Federal Aviation Administration (FAA) to initiate a study within 180 days of enactment. The study's primary objective is to assess the safety and airworthiness of specific aircraft for use in commercial air service conducted under Part 121 of federal regulations. Specifically, it focuses on aircraft with 10 to 19 passenger seats that were type certificated under Part 23 after August 30, 2017. In conducting this assessment, the FAA must consider the economic impacts on operators serving small communities and evaluate foreign regulatory frameworks for similar aircraft. The Administrator is also directed to solicit technical advice and comments from various stakeholders. These include representatives from aircraft manufacturers, small and rural communities experiencing reduced air service, and aviation safety experts knowledgeable in airworthiness requirements. Upon the study's completion, the Administrator is required to submit a comprehensive report detailing its findings to the Committee on Transportation and Infrastructure of the House of Representatives and the Committee on Commerce, Science, and Transportation of the Senate. This report will inform Congress on the potential for safely expanding the types of aircraft used in scheduled commercial air service.
