Comments Invited

We invite interested people to take part in this rulemaking by sending written comments, data, or views. The most helpful comments reference a specific portion of the design criteria, explain the reason for any recommended change, and include supporting data. We ask that you send us two copies of written comments.

We will consider all comments received on or before the closing date for comments. We will consider comments filed late if it is possible to do so without incurring expense or delay. We may change these airworthiness design criteria based on received comments.


The “primary” category for aircraft was created specifically for the simple, low performance personal aircraft. Section 21.17, Designation of applicable Start Printed Page 15993regulations, 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.

Accordingly, Cub Crafters, Inc., has submitted these proposed airworthiness standards for the Model CC21-180 airplane under § 21.17(f).

Proposed Airworthiness Standards for Acceptance Under the Primary Category Rule

This document prescribes airworthiness standards for the issuance of a type certification for the Cub Crafters, Inc., Model CC21-180, a primary category airplane. These proposed airworthiness standards have a long safe service history in similar airplanes; therefore, they provide an appropriate level of safety. The proposed airworthiness standards are based on standards that were used to certify the same design as a normal and utility category airplane, Cub Crafters CC19-180, in accordance with FAA Type Certiciate A00053SE.
