Which Part contains airworthiness standards for Normal Category Rotorcraft?

• A. Part 21
• B. Part 27
• C. Part 23
• D. Part 39

Answer: (B)

For rotorcraft in the normal operating category, the airworthiness standards are in Part 27. This part specifies the design, performance, equipment, and safety requirements a helicopter must meet to be certified for normal operation. Other Parts cover different areas: Part 23 is for normal category airplanes, Part 29 for transport-category rotorcraft, Part 21 covers certification procedures for products and parts, and Part 39 deals with airworthiness directives issued after certification. So, when assessing a normal-category helicopter’s airworthiness standards, Part 27 is the applicable reference.
