Background

The ``primary'' category for aircraft was created specifically for the simple, low performance personal aircraft. Section 21.17(f) provides a means for applicants to propose airworthiness standards for their particular primary category aircraft. The FAA procedure establishing appropriate airworthiness standards includes reviewing and possibly revising the 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.

Discussion of Comments

Existence of Proposed Airworthiness Design Standards for Acceptance

Under the Primary Category Rule; Orlando Helicopter Airways (OHA),

Inc., Models Cessna 172I, 172K, 172L, and 172M airplanes was published in the Federal Register on June 21, 2010, 75 FR 34953. No comments were received, and the airworthiness design standards are adopted as proposed.

Applicability

As discussed above, these airworthiness design standards under the primary category rule are applicable to the C172I, C172K, C172L, and

C172M. Should OHA, Inc., wish to apply these airworthiness design standards to other airplane models, OHA, Inc. must submit a new airworthiness design standard application under the primary rule category.

Conclusion

This action affects only certain airworthiness design standards on

Cessna model C172I, C172K, C172L, C172M airplanes. 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 airplane.
