Final Primary Category Airworthiness Design Standards; AutoGyro 
USA, LLC (AutoGyro) Model Calidus Gyroplane

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Issuance of final Airworthiness Design Standards.

-----------------------------------------------------------------------

SUMMARY: These airworthiness design standards are issued to AutoGyro 
for certification of the Model Calidus gyroplane under the regulations 
for primary category aircraft.

DATES: These airworthiness design standards are effective November 16, 
2015.

FOR FURTHER INFORMATION CONTACT: Gary Roach, Aviation Safety Engineer, 
Regulations and Policy Group, Rotorcraft Directorate, FAA, 10101 
Hillwood Pkwy., Fort Worth, Texas 76177; telephone (817) 222-5110;

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.

Comments

    Proposed Primary Category Airworthiness Design Standards; AutoGyro 
USA, LLC (AutoGyro) Model Calidus Gyroplanes was published in the 
Federal Register on July 24, 2015 (80 FR 43969). One supportive comment 
was received, and the airworthiness design standards are adopted as 
proposed.

Applicability

    These airworthiness design standards under the primary category 
rule are applicable to the Autogyro Model Calidus gyroplane. Should 
Autogyro wish to apply these airworthiness design standards to other 
gyroplane models, Autogyro must submit a new airworthiness design 
standard application under the primary rule category.

Conclusion

    This action affects only certain airworthiness design standards on 
the Autogyro Model Calidus gyroplane. 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 gyroplane.

Citation

    The authority citation for these airworthiness standards is as 
follows:

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