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

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

**SUMMARY :**  We are superseding an existing airworthiness directive (AD) for all Model A330 and A340 series airplanes. 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:

At the end of an escape slide deployment test performed on the left-hand forward pax [passenger]/crew door of an A330 aeroplane, the girt bar attaching the escape slide to the fuselage was found not in a locked position and detached from the aeroplane.
* * * * *

This condition, if not corrected, could result in the slide detaching from the door after being inflated which, during an emergency, would impair the safe evacuation of occupants, possibly resulting in personal injuries.
* * * * * This AD requires actions that are intended to address the unsafe condition described in the MCAI.

**DATES :**  This AD becomes effective May 5, 2011. The Director of the Federal Register previously approved the incorporation by reference of certain documents listed in the AD as of March 19, 2002 (67 FR 6370, February 12, 2002).

**SUPPLEMENTARY INFORMATION :** 

Discussion

On January 31, 2002, we issued AD 2002–02–07, Amendment 39–12635 (67 FR 6370, February 12, 2002). That AD required actions intended to address an unsafe condition on all Model A330 and A340 series airplanes.

Since we issued AD 2002–02–07, Airbus has received certification on two new models: Model A330–223F and -243F airplanes. We are issuing this AD to include them in the requirements of that earlier AD. 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– 0135, dated July 5, 2010 (referred to after this as ‘‘ the MCAI ’’ ), to correct an unsafe condition for the specified products. The MCAI states:

At the end of an escape slide deployment test performed on the left-hand forward pax [passenger]/crew door of an A330 aeroplane, the girt bar attaching the escape slide to the fuselage was found not in a locked position and detached from the aeroplane. The investigation has shown that a component of the slide release mechanism (slider) was found unserviceable (spring function inoperative due to corrosion or missing).

This condition, if not corrected, could result in the slide detaching from the door after being inflated which, during an emergency, would impair the safe evacuation of occupants, possibly resulting in personal injuries.

DGAC [Direction Ge  ́ ne

 ́ rale de l’Aviation Civile] AD F–2001–053R1 and DGAC AD F– 2001–052R2 required the Functional check and lubrication of door girt bar slider and the associated corrective actions.

This [EASA] AD, which supersedes DGAC AD F–2001–053R1 and DGAC AD F–2001– 052R2 retaining their requirements, is issued to extend the applicability to the newly certified models A330–223F and A330–243F, and to clarify the actions required by the superseded AD.

The required actions include repetitive detailed inspection and operational checks of the spring function of the emergency exit door slider mechanism, and applying corrosion inhibitor. Corrective actions include repairing or replacing the slider with a new part. You may obtain further information by examining the MCAI in the AD docket. Changes to the AD

We have revised the applicability of this AD to coordinate with the applicability of the EASA airworthiness directive by specifying the model designations as identified in the U.S. Type Certificate Data Sheets. Model A340–541 and –642 airplanes that were included in the prior FAA AD are not included in this AD, because we have determined that those models are not affected by the identified unsafe condition. FAA’s Determination and Requirements of This AD

This product has been approved by the aviation authority of another


### 22006 Federal Register / Vol. 76, No. 76 / Wednesday, April 20, 2011 / Rules and Regulations

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–2011–0311; Directorate Identifier 2010–NM–232– 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 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. List of Subjects in 14 CFR Part 39

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires inspecting the fuselage surface for corrosion and cracking behind the external adapter plate of the antennae installation, and repair if necessary. This AD was prompted by a report of a crack found behind the external adapter plate of the antennae during inspection. Similar cracking was found on two additional airplanes, and extensive corrosion was found on one airplane. We are issuing this AD to detect and correct corrosion and cracking behind the external adapter plate of the antennae of certain damage-tolerant structure, which could result in reduced structural integrity and consequent rapid depressurization of the airplane.

**DATES :**  This AD is effective May 25,
2011. Examining the AD Docket
