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.
Table--Estimated Costs
----------------------------------------------------------------------------------------------------------------
Average labor Cost per
Action Work hours rate per hour Parts cost airplane
----------------------------------------------------------------------------------------------------------------
Inspection.......................... 20 $80 None................... $1,600
----------------------------------------------------------------------------------------------------------------
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.
