Which CFR part specifically governs airworthiness standards for Normal Category Airplanes?

• A. 14 CFR Part 23
• B. 14 CFR Part 33
• C. 14 CFR Part 61
• D. 14 CFR Part 91

Answer: (A)

Normal Category Airplanes are governed by 14 CFR Part 23. This part is titled Airworthiness Standards: Normal Category Airplanes and sets the certification basis and the design and performance requirements that small, non-transport airplanes must meet to be certified for normal operation. It covers essentials such as structural integrity, flight characteristics, systems and equipment, and the certification process for conformity.

Other parts cover different areas: Part 33 deals with airworthiness standards for aircraft engines, Part 61 handles pilot certification and privileges, and Part 91 covers general operating and flight rules. So the part that directly establishes the airworthiness standards for Normal Category Airplanes is Part 23.
