To require the Administrator of the Federal Aviation Administration to conduct a study to compare the effects of allowing certain aircraft certified under part 23 of title 14, Code of Federal Regulations, to operate under part 121 of such title, and for other purposes.

HR 6448 requires the Federal Aviation Administration (FAA) to study whether newer small aircraft (10-19 seats certified after 2017) could safely operate under commercial airline rules (Part 121) instead of older rules (Part 23). The study must compare safety between pre-1995 aircraft (certified before 1995) and newer models, assess current usage of older aircraft, and evaluate whether airlines would buy newer planes for small communities. It specifically seeks input from rural communities, aviation safety experts, and industry representatives. The FAA must submit a report to Congress within one year, detailing findings on safety, aircraft numbers, purchasing trends, and the economic needs of underserved communities.
