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.
    Accordingly, the applicant, AutoGyro, has submitted a request to 
the FAA to include the following:
