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

**ACTION :**  Final rule; request for
comments.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for certain Airbus Model A330–201, –202, –203, –223, –243, –301, –302, –303, –321, –322, –323, –341, –342, and –343 airplanes; and Model A340–200 and –300 series airplanes. This AD requires repetitive inspections of the main fitting and sliding tube of the nose landing gear (NLG) for defects, damage, and cracks, and corrective actions if necessary. This AD was prompted by reports of a cracked main fitting and sliding tube during overhaul of NLGs. We are issuing this AD to detect and correct cracks, defects, or damage of the main fitting and sliding tube of the NLG, which could result in failure of the main fitting or sliding tube, and consequent NLG collapse.

**DATES :**  This AD becomes effective April 30, 2012.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of April 30, 2012.

We must receive comments on this AD by May 29, 2012.

**SUPPLEMENTARY INFORMATION :** 

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010–0034, dated March 5, 2010, corrected March 8, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI
states:

During the overhaul of two different Nose Landing Gears (NLG), cracks were found on the main fitting of one and the sliding tube of the other. Investigations concluded that the cracks initiated as a result of residual stress in the parts following damage due to impact during towing incidents.

A subsequent review of the reported incidents has led to conclude that an inspection of the main fitting and sliding tube is required on those NLG that have sustained impacts as result of towing incidents.

The failure of the main fitting or sliding tube could lead to NLG collapse.

To prevent the above unsafe condition, this [EASA] AD requires a one-time [detailed] inspection followed by repetitive inspections of the main fitting and sliding tube of the NLG serial numbers listed in the Applicability section of this [EASA] AD: —One time Magnetic Particle Inspection

(MPI) of the affected areas to detect any crack, —Repetitive Detailed Visual Inspections

(DVI) of the affected areas to detect any damage of the surface protections or corrosion. This [EASA] AD also requires the accomplishment of the associated corrective actions, as necessary.
* * * * * Required corrective actions include removing the labels if there is evidence of sealant damage or moisture ingress behind the labels. If surface treatment damage is found, the required actions are removing the paint and cadmium prior to the MPI, removing any surface defects, flap peening and replacing protective coatings, and replacing cracked parts with serviceable parts. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Airbus has issued Mandatory Service Bulletin A330–32–3233, dated October 22, 2009 (for Model A330 airplanes); and Mandatory Service Bulletin A340– 32–4275, dated October 22, 2009 (for Model A340 airplanes). 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 another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future.

FAA’s Determination of the Effective Date

Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary.

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–2012–0296; Directorate Identifier 2010–NM–106– 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://


### 22189 Federal Register / Vol. 77, No. 72 / Friday, April 13, 2012 / Rules and Regulations

www.regulations.gov , including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. 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);

3. Will not affect intrastate aviation in Alaska; and

4. 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

**SUPPLEMENTARY INFORMATION :**  History

On December 14, 2011, the FAA published in the Federal Register a notice of proposed rulemaking to amend Class E airspace at Columbia, SC, and establish Class E airspace at Pelion, SC, Docket No. FAA–2011–1196 (76 FR 77727). 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 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 Part 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 Columbia, SC, by removing Corporate Airport from the airspace designation and establishes Class E airspace at Pelion, SC, to support new Standard Instrument Approach Procedures at Lexington County Airport at Pelion, Pelion, SC, formerly Corporate Airport. Airspace reconfiguration is necessary due to the design of new arrival procedures, and for continued safety
