. 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.

**[Docket No. 31038; Amdt. No. 3662]**
**Standard Instrument Approach Procedures, and Takeoff Minimums**  **and Obstacle Departure Procedures; Miscellaneous Amendments** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

**DATES :**  This rule is effective October 15, 2015. The compliance date for each SIAP, associated Takeoff Minimums, and ODP is specified in the amendatory provisions.
