Airworthiness Directives; Airbus Model A380-800 Series Airplanes

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:

A crack has been found on the Droop Nose (DN) 1 master sidestay bracket on the inboard leading edge of an Airbus A380 flight test aeroplane.

In case of failure of the master bracket, the sub-master bracket would be able to sustain limit loads but not ultimate loads.

This condition, if not detected and corrected, could lead to a DN failure which would affect the structural integrity of that wing area.

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 2009-0213, dated October 8, 2009 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

A crack has been found on the Droop Nose (DN) 1 master sidestay bracket on the inboard leading edge of an Airbus A380 flight test aeroplane.

In case of failure of the master bracket, the sub-master bracket would be able to sustain limit loads but not ultimate loads.

This condition, if not detected and corrected, could lead to a DN failure which would affect the structural integrity of that wing area.

This AD requires an inspection programme to detect any crack in the DN 1 master sidestay bracket and subsequently in the sub-master bracket, and the accomplishment of the associated corrective actions, as applicable.

Corrective actions include replacing the cracked DN 1 master sidestay bracket, performing a detailed visual inspection for cracks of the associated DN 1 sub-master sidestay bracket, and contacting Airbus if cracks are found on the DN 1 sub-master sidestay bracket. 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 A380-57-8019, dated August 5, 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 Proposed 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 This 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 proposed 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 proposed 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-2010-0763; Directorate Identifier 2009-NM-253-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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation:

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 proposed AD and placed it in the AD docket.

Affected ADs Back to Top

(b) None.

Applicability Back to Top

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

Subject Back to Top

Compliance Back to Top

(f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

Actions Back to Top

(g) Before the accumulation of 1,250 total flight cycles or within 30 days after the effective date of this AD, whichever occurs later, do a detailed visual inspection (DVI) of the left-hand and right-hand DN 1 master sidestay brackets to detect cracks, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A380-57-8019, dated August 5, 2009.

(1) If no cracks are found, repeat the inspection at intervals not to exceed 1,250 flight cycles.

(2) If any crack is found, before further flight, replace the cracked DN 1 master sidestay bracket and perform a DVI for cracks of the associated DN 1 sub-master sidestay bracket, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A380-57-8019, dated August 5, 2009.

(i) If no crack is found during the inspection specified in paragraph (g)(2) of this AD, repeat the inspection of the DN 1 master sidestay brackets specified in paragraph (g) of this AD at intervals not to exceed 1,250 flight cycles.

(ii) If any crack is found during the inspection specified in paragraph (g)(2) of this AD, before further flight, contact Airbus and repair in accordance with a method approved by the Manager, International Branch, ANM 116, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (EASA) (or its delegated agent).

(h) Replacement of cracked DN 1 master sidestay brackets, as specified in paragraph (g)(2) of this AD, is not a terminating action for the repetitive inspections required by this AD.
