Airworthiness standards for small airplanes with nine or fewer seats in the normal utility and acrobatic categories are found in which regulation?

• A. 14 CFR Part 21
• B. Supplemental Type Certificate
• C. 14 CFR Part 27
• D. 14 CFR Part 23

Answer: (D)

Airworthiness standards for small airplanes with nine or fewer seats in the normal, utility, and acrobatic categories are defined in 14 CFR Part 23. This part specifically covers light, general aviation airplanes and sets the design, performance, and safety requirements they must meet to be certificated and operated. It distinguishes these airplanes from other regulations that cover different areas: Part 21 deals with certification procedures and approvals, a Supplemental Type Certificate relates to changes after certification, and Part 27 governs rotorcraft (helicopters).
