SUPPLEMENTARY INFORMATION: Any person may obtain a copy of this 
information by contacting the person named above under FOR FURTHER 
INFORMATION CONTACT.

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.

follows:

    Authority: 49 U.S.C. 106(g), 40113 and 44701.
