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: erowe on DSK5CLS3C1PROD with RULES 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. ADDRESSES: You may send comments by any of the following methods: VerDate Nov<24>2008 13:48 Dec 30, 2009 Jkt 220001 You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

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. PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 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– E:\FR\FM\31DER1.SGM 31DER1
