### 51463 Federal Register / Vol. 77, No. 165 / Friday, August 24, 2012 / Rules and Regulations

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2012– 0097–E, dated May 31, 2012, and AD 2012–0097R1, dated June 1, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

Reports from the field confirmed a noncompliance of the pressure side fuel hoses installed on certain P/N 893114 fuel pumps, which may have resulted in a latent defect on a limited number of engines. The affected hoses may not be fuel resistant in accordance with the specification. This condition, if not corrected, could lead to detachment of particles from the fuel hose and irregularities in the carburetor function, possibly resulting in in-flight engine shutdown, and forced landing, damage to the aeroplane and injury to occupants. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

BRP-Powertrain GmbH & Co KG has issued Alert Service Bulletin No. ASB– 912–061R1, dated May 31, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This AD

This product has been approved by the aviation authority of Austria, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This AD requires replacing the pressure side fuel hose on certain fuel pumps and inspecting the carburetors connected to those fuel pumps for contamination within 5 flight hours after the effective date of the AD.

FAA’s Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the compliance time in this AD is within 5 flight hours after the effective date of the AD. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include ‘‘Docket No. FAA–2012–0603; Directorate Identifier 2012–NE–17–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those
comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of the Web site, anyone can find and read the comments in any of our dockets, including, if provided, the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You may review the DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477–78).
Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this AD:

1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866;

2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39

**Amendment of Class E Airspace; Augusta, GA** 

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

**ACTION :**  Final rule.

**SUMMARY :**  This action amends Class E Airspace in Augusta, GA. The Bushe Non-Directional Beacon (NDB) and the Burke County NDB have been decommissioned and new Standard Instrument Approach Procedures have been developed at Augusta Regional Airport at Bush Field, Augusta, GA, and Burke County Airport, Waynesboro, GA, respectively. Airspace reconfiguration is necessary for the continued safety and management of instrument flight rules (IFR) operations within the Augusta, GA, airspace area. This action also updates the geographic coordinates of Burke County Airport.

**DATES :**  Effective 0901 UTC, November 15, 2012. The Director of the Federal Register approves this incorporation by reference action under title 1, Code of Federal Regulations, part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments.

**SUPPLEMENTARY INFORMATION :**  History

On April 10, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to amend Class E airspace in the Augusta, GA area (77 FR 21506). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Subsequent to publication, the FAA found an error in the latitudinal coordinate for Burke County Airport and makes the correction in the rule. Except for editorial changes, and the change noted above, this rule is the same as published in the NPRM.

Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9V dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order.

The Rule

This amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 amends Class E airspace extending upward from 700 feet above the surface at Augusta, GA. Airspace reconfiguration is necessary due to the decommissioning of the Bushe NDB at Augusta Regional at Bush Field Airport, Augusta, GA, and the Burke County NDB at Burke County Airport, Waynesboro, GA, thereby cancelling the NDB approaches. This action ensures the continued safety and management of IFR operations within the Augusta, GA airspace area. This action also adjusts the latitude degree coordinate of the Burke County Airport from 32 ° to 33 ° to be in concert with the FAA’s aeronautical database.

The FAA has determined that this regulation only involves an established
