What does FAR part 23 specifically regulate?

FAR part 23 specifically regulates general aviation airplanes, which refers to the design, performance, and airworthiness standards applicable to smaller aircraft typically used for personal or recreational flying, flight training, and other non-commercial purposes. This regulation establishes requirements that these airplanes must meet to ensure they are safe for flight, covering aspects such as flight performance, design structure, and safety equipment.

The scope of FAR part 23 allows for innovation and flexibility in the design of general aviation aircraft while maintaining high safety standards. This is crucial since general aviation encompasses a wide variety of aircraft with differing capabilities and uses.

Other options pertain to different areas of aviation regulation. Commercial air transport is regulated under a different part that addresses larger aircraft and commercial operations. Air traffic control procedures are covered under separate regulations that focus on managing air traffic safely and efficiently. Aircraft maintenance standards also fall under distinct regulations that specify procedures for ensuring aircraft are maintained in an airworthy condition.
