Airworthiness Directives; Construcciones Aeronauticas, S.A. 
(CASA), Model C-212-DF Airplanes

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

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain CASA Model C-212-DF airplanes. This AD requires a one-time 
conductivity inspection to determine the material used in manufacturing 
outer to center wing attachment fittings; and one-time inspections to 
detect cracks on affected fittings, and corrective action if necessary. 
This AD results from reports of cracks found in outer to center wing 
attachment fittings. We are issuing this AD to detect and correct 
cracks on the upper and lower fittings in both outer and center wings, 
which could result in reduced structural integrity of the airplane.

DATES: This AD becomes effective March 9, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of March 9, 2009.
    We must receive comments on this AD by March 23, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, notified us that 
an unsafe condition may exist on certain CASA Model C-212-DF airplanes. 
The EASA advises that cracks were discovered in outer to center wing 
attachment fittings during final assembly of a new production airplane 
and in some inspected airplanes already in service. The cracks were 
caused by a defective manufacturing process of the outer to center wing 
attachment fittings. This condition, if not detected and corrected, 
could result in reduced structural integrity of the airplane.

Relevant Service Information

    CASA has issued Communication Letter COM 212-303, dated March 16, 
2006. This communication letter describes procedures to determine the 
material used in the manufacture of outer to center wing attachment 
fittings.
    CASA also has issued Communication Letter COM 212-301, Revision 1, 
dated March 4, 2006. This communication letter describes procedures for 
a high frequency eddy current inspection to detect cracks of the eight 
upper and lower fittings in both outer and center wings for both left-
hand and right-hand sides of the airplane.
    In addition, CASA has issued Communication Letter COM 212-302, 
Revision 1, dated March 17, 2006. This communication letter describes 
procedures for a low frequency eddy current inspection to detect cracks 
of the eight upper and lower fittings in both outer and center wings 
for both left-hand and right-hand sides of the airplane.
    The EASA mandated the service information and issued emergency 
airworthiness directive (AD) 2006-0359-E, dated November 29, 2006 
(referred to after this as ``the MCAI''), to ensure the continued 
airworthiness of these airplanes in the European Union.
    The service bulletins do not specify a method for repairing or 
replacing wing attachment fittings. This AD requires replacing cracked 
fittings using a method approved by the FAA or EASA (or its delegated 
agent). In light of the type of repair that would be required to 
address the unsafe condition, and consistent with existing bilateral 
airworthiness agreements, we have determined that, for this AD, a 
repair approved by the FAA or EASA (or its delegated agent) is 
acceptable for compliance with this AD.

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 an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    Therefore, we are issuing this AD to require determination of the 
material used in manufacturing outer to center wing attachment 
fittings; and one-time inspections to detect cracks on affected 
fittings, and corrective action if necessary. This AD requires 
accomplishing the actions specified in the service information 
described previously, except as discussed below.

Difference Between This AD and the MCAI

    The compliance time specified in the EASA airworthiness directive 
is the effective date of the MCAI. We have determined that a compliance 
time of 10 flight hours is appropriate and will provide an acceptable 
level of safety.

Costs of Compliance

    None of the airplanes affected by this action are on the U.S. 
Register. All airplanes affected by this AD are currently operated by 
non-U.S. operators under foreign registry; therefore, they are not 
directly affected by this AD action. However, we consider this AD 
necessary to ensure that the unsafe condition is addressed if any 
affected airplane is imported and placed on the U.S. Register in the 
future.
    The following table provides the estimated costs to comply with 
this AD for any affected airplane that might be imported and placed on 
the U.S. Register in the future.

----------------------------------------------------------------------------------------------------------------

FAA's Determination of the Effective Date

    No airplane affected by this AD is currently on the U.S. Register. 
Therefore, providing notice and opportunity for public comment is 
unnecessary before this AD is issued, and this AD may be made effective 
in less than 30 days after it is published in the Federal Register.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2008-1360; Directorate Identifier 2008-NM-075-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory,

[[Page 7788]]

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 have 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 that the 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
