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 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:

As a result of the Movable Flap Track Fairing (MFTF) 6 crack findings (ref. AD 2008-0216), a detailed review has been launched for all MFTF 2 to 6. This investigation has revealed some cracking at MFTF 4 pivot support-ring.

This condition, if not corrected, could lead to in-flight loss of MFTF 4, potentially resulting in injuries to persons on the ground.

* * * * *

This AD requires actions that are intended to address the unsafe condition described in the MCAI.

DATES: This AD becomes effective January 15, 2010.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of January 15, 2010.

We must receive comments on this AD by February 16, 2010.

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 2009-0113, dated May 27, 2009 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:

As a result of the Movable Flap Track Fairing (MFTF) 6 crack findings (ref. AD 2008-0216), a detailed review has been launched for all MFTF 2 to 6. This investigation has revealed some cracking at MFTF 4 pivot support-ring.

This condition, if not corrected, could lead to in-flight loss of MFTF 4, potentially resulting in injuries to persons on the ground.

To prevent the risk of a MFTF 4 detachment, this AD requires an inspection programme and/or replacement of the fairings in order to ensure they are removed from service before any crack becomes critical.

You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Airbus has issued Mandatory Service Bulletin A380-57-8016, dated

May 11, 2009. 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.

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-2009-1211; Directorate

Identifier 2009-NM-121-

Page 69261

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.

Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2009-26-10 AIRBUS: Amendment 39-16149. Docket No. FAA-2009-1211;

Directorate Identifier 2009-NM-121-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective January 15, 2010.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Airbus Model A380-841, -842, and -861 airplanes; certificated in any category; all serial numbers.

Subject

(d) Air Transport Association (ATA) of America Code 57: Wings.

Reason

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

As a result of the Movable Flap Track Fairing (MFTF) 6 crack findings (ref. AD 2008-0216), a detailed review has been launched for all MFTF 2 to 6. This investigation has revealed some cracking at MFTF 4 pivot support ring.

This condition, if not corrected, could lead to in-flight loss of MFTF 4, potentially resulting in injuries to persons on the ground.

To prevent the risk of a MFTF 4 detachment, this AD requires an inspection programme and/or replacement of the fairings in order to ensure they are removed from service before any crack becomes critical.
