Air taxi operations are governed by which FAR Part?

• A. Part 125
• B. Part 1841
• C. Part 1462
• D. Part 135

Answer: (D)

Air taxi operations are regulated under 14 CFR Part 135, which is focused on commuter and on-demand (air taxi) flight. This part establishes the certification, operating rules, crew qualifications, maintenance standards, and operating procedures specifically for non-scheduled, for-hire services using smaller aircraft. It sits between general flight rules (Part 91) and scheduled airline operations (Part 121), providing the framework that enables flexible, on-demand transport while maintaining safety standards. The other options cover different kinds of operations—Part 125 deals with larger aircraft charter, Part 121 covers scheduled carriers, and the remaining parts are not the governing framework for air taxi services. So the regulation that governs air taxi operations is 14 CFR Part 135.
