Airworthiness Directives; Airbus Airplanes

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 certain 
Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321, 
-322, -323, -341, -342, and -343 airplanes; and Model A340-200 and -300 
series airplanes. This AD requires repetitive inspections of the main 
fitting and sliding tube of the nose landing gear (NLG) for defects, 
damage, and cracks, and corrective actions if necessary. This AD was 
prompted by reports of a cracked main fitting and sliding tube during 
overhaul of NLGs. We are issuing this AD to detect and correct cracks, 
defects, or damage of the main fitting and sliding tube of the NLG, 
which could result in failure of the main fitting or sliding tube, and 
consequent NLG collapse.

DATES: This AD becomes effective April 30, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of April 30, 
2012.
    We must receive comments on this AD by May 29, 2012.

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 2010-0034, dated March 5, 2010, corrected March 
8, 2010 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    During the overhaul of two different Nose Landing Gears (NLG), 
cracks were found on the main fitting of one and the sliding tube of 
the other. Investigations concluded that the cracks initiated as a 
result of residual stress in the parts following damage due to 
impact during towing incidents.
    A subsequent review of the reported incidents has led to 
conclude that an inspection of the main fitting and sliding tube is 
required on those NLG that have sustained impacts as result of 
towing incidents.
    The failure of the main fitting or sliding tube could lead to 
NLG collapse.
    To prevent the above unsafe condition, this [EASA] AD requires a 
one-time [detailed] inspection followed by repetitive inspections of 
the main fitting and sliding tube of the NLG serial numbers listed 
in the Applicability section of this [EASA] AD:

--One time Magnetic Particle Inspection (MPI) of the affected areas 
to detect any crack,
--Repetitive Detailed Visual Inspections (DVI) of the affected areas 
to detect any damage of the surface protections or corrosion.

    This [EASA] AD also requires the accomplishment of the 
associated corrective actions, as necessary.
* * * * *
Required corrective actions include removing the labels if there is 
evidence of sealant damage or moisture ingress behind the labels. If 
surface treatment damage is found, the required actions are removing 
the paint and cadmium prior to the MPI, removing any surface defects, 
flap peening and replacing protective coatings, and replacing cracked 
parts with serviceable parts. You may obtain further information by 
examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A330-32-3233, dated 
October 22, 2009 (for Model A330 airplanes); and Mandatory Service 
Bulletin A340-32-4275, dated October 22, 2009 (for Model A340 
airplanes). 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.

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-2012-0296; Directorate 
Identifier 2010-NM-106-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://

[[Page 22189]]

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);
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
