The “primary” category for aircraft was created specifically for the simple, low performance personal aircraft. Section 21.17, Designation of applicable regulations, paragraph (f) provides a means for the FAA to determine appropriate airworthiness standards for the particular primary category aircraft. The FAA procedure establishing appropriate airworthiness standards includes reviewing and possibly revising an applicant's proposal, publication of the submittal in the Federal Register for public review and comment, and addressing the comments. After all necessary revisions, the standards are published as approved FAA airworthiness standards. This document prescribes airworthiness standards for the issuance of a type certificate for the Cub Crafters, Inc., Model CC21-180, a primary category airplane. These airworthiness standards have a long safe service history in similar airplanes; therefore, they provide an appropriate level of safety. These airworthiness standards are based on standards that were used to certificate the same design as a normal and utility category airplane, Cub Crafters Model CC19-180, in accordance with FAA Type Certiciate A00053SE.[1]


Proposed Primary Category Design Standards; Cub Crafters, Inc., Model CC21-180 Airplane was published in the Federal Register on April 17, 2019 (84 FR 15992). No comments were received, and the airworthiness design standards are adopted as proposed.


These airworthiness design standards under the primary category rule are applicable to the Cub Crafters, Inc., Model CC21-180 airplane. Should Cub Crafters, Inc. wish to apply these airworthiness design standards to other airplane models, it must submit a new airworthiness design standard application under the primary rule category.


This action affects only certain airworthiness design standards on the Cub Crafters, Inc., Model CC21-180 airplane. It is not a standard of general applicability and it affects only the applicant who applied to the FAA for approval of these features on the rotorcraft.
