The AMOC approval letter must specifically reference this AD.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

(3) Reporting Requirements: A Federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number.

**[Docket No. FAA–2011–0439; Airspace Docket No. 11–ANM–10]** 



### Amendment of Class D and Class E **Airspace and Establishment of Class E Airspace; Casper, WY** 

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Final rule.

**SUMMARY** 

### : This action amends Class D and Class E airspace at Casper, Natrona County International Airport, Casper, WY, by adjusting the geographic coordinates of the airport. This action also establishes Class E En Route Domestic airspace at the airport to improve the safety and management of IFR operations.

**DATES** 

### : Effective date, 0901 UTC, October 20, 2011. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments.

**SUPPLEMENTARY INFORMATION** 

### : History

On June 21, 2011, the FAA published in the Federal Register a notice of proposed rulemaking to amend controlled airspace at Casper, WY (76 FR 36017). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.

Class D and Class E airspace designations are published in paragraphs 5000, 6002, 6004, 6005 and 6006, respectively, of FAA Order 7400.9U dated August 18, 2010, and effective September 15, 2010, which is incorporated by reference in 14 CFR 71.1. The Class D and Class E airspace designations listed in this document will be published subsequently in that Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by amending Class D airspace, Class E surface airspace, Class E airspace designated as an extension, and Class E airspace extending upward from 700/ 1,200 feet above the surface, by adjusting the geographic coordinates of Casper, Natrona County International Airport to be in concert with the FAA’s aeronautical database. Also, this action establishes Class E en route domestic airspace extending upward from 1,200 feet above the surface to facilitate vectoring of Instrument Flight Rules (IFR) traffic from en route airspace to the airport. This enhances the safety and management of IFR operations at the airport.

The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, section 106 discusses the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in subtitle VII, part A, subpart I, section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of

airspace. This regulation is within the scope of that authority as it establishes additional controlled airspace at Casper, Natrona County International Airport, Casper, WY. List of Subjects in 14 CFR Part 71
