**SUPPLEMENTARY INFORMATION :** 

Discussion

The European Aviation Safety Agency (EASA), which is the aviation authority for the Member States of the European Community, has issued EASA Airworthiness Directive 2010–0036, dated March 8, 2010 (referred to after this as ‘‘the MCAI ’’ ), to correct an unsafe condition for the specified products. The MCAI states:

The airworthiness limitations are currently included in Airbus A340 Airworthiness Limitations Section (ALS).

The airworthiness limitations applicable to Damage Tolerant Airworthiness Limitation Items (DT ALI) are currently given in Airbus A340 ALI Document reference AI/SE–M4/ 95A.0051/97, which is approved by the European Aviation Safety Agency (EASA) and referenced in Airbus Airworthiness Limitations Section (ALS) Part 2.

The issue 11 of Airbus A340 ALI Document introduces more restrictive maintenance requirements/airworthiness limitations. Failure to comply with this issue 11 constitutes an unsafe condition.

This new [EASA] AD retains the requirements of EASA AD 2007–0158, which is superseded, and requires the implementation of the more restrictive maintenance requirements/airworthiness limitations as specified in Airbus A340 ALI Document AI/SE–M4/95A.0051/97 issue 11.
The unsafe condition is fatigue cracking, damage, and corrosion in certain structure, which could result in reduced structural integrity of the airplane. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Airbus has issued A340 Airworthiness Limitation Items, Document AI/SE–M4/95A.0051/97, Issue 11, dated February 20, 2009. This document provides the mandatory time for maintenance tasks, structural inspection intervals, and related structural inspection procedures. 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.

Differences Between the AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the AD.


### 8611 Federal Register / Vol. 76, No. 31 / Tuesday, February 15, 2011 / Rules and Regulations

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–2011–0040; Directorate Identifier 2010–NM–185– 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 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); 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

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

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

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new AD:

2011–04–06 Airbus: Amendment 39–16606. Docket No. FAA–2011–0040; Directorate Identifier 2010–NM–185–AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective March 2, 2011.

Affected ADs

(b) None.
Applicability

(c) This AD applies to Airbus Model A340– 211, –212, and –213 airplanes; A340–311, –312, and –313 airplanes; A340–541 airplanes; and A340–642 airplanes; certificated in any category; all manufacturer serial numbers.

Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (i)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. Subject (d) Air Transport Association (ATA) of America Code 05.

Reason

(e) The mandatory continuing airworthiness information (MCAI) European Aviation Safety Agency (EASA) AD 2009–
0192 states:

The airworthiness limitations are currently included in Airbus A340 Airworthiness Limitations Section (ALS).

The airworthiness limitations applicable to Damage Tolerant Airworthiness Limitation Items (DT ALI) are currently given in Airbus A340 ALI Document reference AI/SE–M4/ 95A.0051/97, which is approved by the European Aviation Safety Agency (EASA) and referenced in Airbus Airworthiness Limitations Section (ALS) Part 2.

The issue 11 of Airbus A340 ALI Document introduces more restrictive maintenance requirements/airworthiness limitations. Failure to comply with this issue 11 constitutes an unsafe condition.

This new [EASA] AD retains the requirements of EASA AD 2007–0158, which is superseded, and requires the implementation of the more restrictive maintenance requirements/airworthiness limitations as specified in Airbus A340 ALI Document AI/SE–M4/95A.0051/97 issue 11. The unsafe condition is fatigue cracking, damage, and corrosion in certain structure, which could result in reduced structural integrity of the airplane.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI (European Aviation Safety Agency AD 2009–0192) describes the unsafe condition as:

Performing some quality tests on material, Airbus found that some 300M steel forgings used to manufacture certain landing gear components were below specification limits. Adapted airworthiness limitations were introduced in Airbus A340 Airworthiness Limitations Section (ALS) Part 1 ‘‘ Safe Life Airworthiness Limitation Items (SL ALI) ’’ for different source route codes.
* * * * *

This [EASA] AD introduces more restrictive life limitations for several landing gear components.

The MCAI (EASA AD 2010–0131) describes the unsafe condition as:
* * * * *

The revision 04 of Airbus A330 and A340 ALS Part 1 introduces more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A330 and A340 ALS Part 1 revision
04.
The unsafe condition is failure of certain life-limited parts, which could result in reduced structural integrity of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

**DATES :**  This AD becomes effective March 2, 2011.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 2, 2011.

We must receive comments on this AD by April 1, 2011.
