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 2008-0012, dated January 14, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Based on some recent in-service findings for fluid ingress and/
or inner skin disbond damage on rudders which could result in 
reduced structural integrity of the rudder, AIRBUS decided to 
introduce some further structural inspections to specific rudder 
areas:

--A special detailed one time structural inspection to specific 
rudder areas to ensure earlier detection of damage at the inspected 
areas,
--A repetitive specific ultrasonic inspection along the complete 
rudder panel front and bottom edges (complete z-profile area along 
the spar and the bottom rib) to detect any damage in this area.

    The aim of this Airworthiness Directive (AD) is to render 
mandatory this additional inspection program in order to maintain 
the structural integrity of the rudder.

The special detailed one-time structural inspection consists of doing a 
thermography or x-ray inspection and an ultrasonic inspection to detect 
damage of the rudders at the rudder hoisting points and trailing edge 
screw areas. The corrective actions depend on the findings and the 
extent of the damage found, and include doing the repair or contacting 
Airbus and following their repair instructions.
    The repetitive ultrasonic inspection along the complete rudder 
panel front and bottom edges (complete z-profile area along the spar 
and the bottom rib) to detect damage also includes doing related 
investigative and corrective actions. The related investigative action 
is a thermography inspection for inner skin disbond damage and fluid 
ingress on the rudder. The corrective actions depend on the findings 
and the extent of the damage found, and may include venting the core (a 
temporary repair), and contacting Airbus and following their repair 
instructions for a permanent repair.
    The compliance time for the corrective actions for the special 
detailed one-time structural inspection ranges between ``before further 
flight'' and 4,500 flight cycles, depending on the damage finding. The 
compliance time for the corrective actions for the repetitive 
ultrasonic inspections ranges between ``before further flight'' and 
2,500 flight cycles, depending on the damage finding and whether the 
temporary repair is done. The repetitive interval for the ultrasonic 
inspections is 5,000 flight cycles, except after doing the temporary 
repair, in which case the interval is 500 flight cycles until a 
permanent repair is done, after which time the interval is 5,000 flight 
cycles.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued the following service bulletins:
     Airbus Mandatory Service Bulletin A330-55-3037, including 
Appendix 01, dated October 11, 2007;
     Airbus Mandatory Service Bulletin A330-55-3038, dated 
November 7, 2007;
     Airbus Mandatory Service Bulletin A340-55-4033, including 
Appendix 01, dated October 11, 2007; and
     Airbus Mandatory Service Bulletin A340-55-4034, dated 
November 7, 2007.
    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

[[Page 23624]]

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-2009-0449; Directorate 
Identifier 2008-NM-034-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.

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows: No differences.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, Transport Airplane Directorate, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. Send information to ATTN: Dan
