Final Rule; Request For Comments.

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 describes the unsafe condition as:

Following a query from an operator, investigations revealed that some MSN [manufacturer serial number], for which Airbus modification 40391 was indicated as fully embodied inside the Aircraft Inspection Report (AIR), did not have Modification Proposal (MP-S10437) which is part of this modification embodied in production.

As a result, ALI [Airworthiness Limitation Item] task 533105-01-02 has not been performed on the MSN listed in the applicability section of this AD, which constitutes an unsafe condition.

* * * * *

The unsafe condition is fatigue cracking of the internal structure of the fuselage, which could adversely affect the structural integrity of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

DATES: Back to Top

This AD becomes effective August 1, 2011.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of August 1, 2011.

Discussion Back to Top

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010-0173, dated August 17, 2010 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

Airworthiness Limitation Item (ALI) task 533105-01-02 is applicable to aeroplanes on which Airbus modification 40391 has not been embodied in production. The requirements associated to this task are applicable to aeroplanes on which Modification Proposal (MP-S10437) has not been embodied.

Following a query from an operator, investigations revealed that some MSN [manufacturer serial numbers], for which Airbus modification 40391 was indicated as fully embodied inside the Aircraft Inspection Report (AIR), did not have Modification Proposal (MP-S10437) which is part of this modification embodied in production.

As a result, ALI task 533105-01-02 has not been performed on the MSN listed in the applicability section of this AD, which constitutes an unsafe condition.

For the reasons described above, this AD requires repetitive special detailed inspections [for fatigue cracking of the internal structure of the fuselage] corresponding to ALI task 533105-01-02 and the accomplishment of the associated corrective actions.

The unsafe condition is fatigue cracking of the internal structure of the fuselage, which could adversely affect the structural integrity of the airplane. The special detailed inspection is defined as an ultrasonic inspection in this AD. The corrective action is repairing any cracks in accordance with a method approved by the FAA or EASA (or its delegated agent). You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information Back to Top

Airbus has issued Mandatory Service Bulletin A330-53-3185, including Appendices 01 and 02, dated May 20, 2010. 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 Back to Top

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 Back to Top

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.

FAA's Determination of the Effective Date Back to Top

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

Comments Invited Back to Top

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-2011-0653; Directorate Identifier 2010-NM-249-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 Back to Top

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 Back to Top

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.

Subject Back to Top

(d) Air Transport Association (ATA) of America Code 53: Fuselage.

Reason Back to Top

(e) The mandatory continued airworthiness information (MCAI) states:

* * * * *

Following a query from an operator, investigations revealed that some MSN, for which Airbus modification 40391 was indicated as fully embodied inside the Aircraft Inspection Report (AIR), did not have Modification Proposal (MP-S10437) which is part of this modification embodied in production.

As a result, ALI [Airworthiness Limitation Item] task 533105-01-02 has not been performed on the MSN listed in the applicability section of this AD, which constitutes an unsafe condition.
