Rotorcraft with an MTOW greater than 7,000 lbs and 10 or more passengers are type certified under which FAR part?

Rotorcraft with a Maximum Takeoff Weight (MTOW) greater than 7,000 pounds and designed to carry 10 or more passengers fall under the requirements of FAR Part 29. This part specifically governs the airworthiness standards for transport category rotorcraft. It is crucial for such rotorcraft to meet stringent safety and performance criteria, which Part 29 establishes, to ensure their operational safety and reliability.

FAR Part 21, on the other hand, relates to the certification procedures for different aircraft types but does not specifically address the airworthiness standards for rotorcraft. FAR Part 27 deals with the airworthiness standards for normal category rotorcraft, which do not exceed the specified weight and passenger capacity limits detailed in Part 29. FAR Part 41 pertains to the registration and certification of civil aircraft but is not applicable to rotorcraft certification specifically.

Thus, the correct categorization of rotorcraft with the specified MTOW and passenger capacity is adequately covered under FAR Part 29, which sets forth the necessary standards for operation within the transport category.
