Which regulation provides the airworthiness standards for an airplane certificated in the normal category?

• A. 14 CFR Part 39
• B. 14 CFR Part 23
• C. 14 CFR Part 25
• D. 14 CFR Part 91

Answer: (B)

The airworthiness standards for a normal-category airplane are defined in 14 CFR Part 23. This part lays out the design, performance, and equipment requirements for small airplanes that fall into the normal category (and related categories like utility, aerobatic, and commuter within Part 23). It specifies what the airplane must be capable of in terms of structure, systems, stability, and overall safety to be certified. Understanding the other regulations helps place this in context: Part 39 covers airworthiness directives issued to address unsafe conditions after certification, Part 25 applies to transport-category airplanes (the large airliners), and Part 91 contains operating rules rather than design standards.
