AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
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:
During removal of forward and aft wing links, corrosion has been
found on the wing links and the wing link attachment bolts in areas
that are not readily accessible during the currently required
Maintenance Review Board Report (MRBR) zonal inspections or
Corrosion Prevention and Control Programme (CPCP) inspections. If
left uncorrected, such corrosion could adversely affect the
structural integrity of the wing to fuselage joint.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective April 2, 2009.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 2,
2009.
ADDRESSES: You may examine the AD docket on the Internet at http://
www.regulations.gov or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on October 31, 2008 (73
FR 64897). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
During removal of forward and aft wing links, corrosion has been
found on the wing links and the wing link attachment bolts in areas
that are not readily accessible during the currently required
Maintenance Review Board Report (MRBR) zonal inspections or
Corrosion Prevention and Control Programme (CPCP) inspections. If
left uncorrected, such corrosion could adversely affect the
structural integrity of the wing to fuselage joint.
For this reason, this Airworthiness Directive (AD) requires
repetitive detailed visual inspections at the forward and aft wing
links and wing link attachment bolts for
[[Page 8725]]
signs of corrosion, replacement of corroded nuts and bolts and
repair of any defects.
The MRBR and CPCP will be amended to include the repeat
inspections. You may obtain further information by examining the MCAI
in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Differences Between This 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 MCAI in order to follow our FAA policies. Any such differences
are highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect about 1 product of U.S.
registry. We also estimate that it will take about 20 work-hours per
product to comply with the basic requirements of this AD. The average
labor rate is $80 per work-hour. Based on these figures, we estimate
the cost of this AD to the U.S. operators to be $1,600.
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.
Examining the AD Docket
You may examine the AD docket on the Internet at http: //
www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

Subject
(d) Air Transport Association (ATA) of America Code 53:
Fuselage.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During removal of forward and aft wing links, corrosion has been
found on the wing links and the wing link attachment bolts in areas
that are not readily accessible during the currently required
Maintenance Review Board Report (MRBR) zonal inspections or
Corrosion Prevention and Control Programme (CPCP) inspections. If
left uncorrected, such corrosion could adversely affect the
structural integrity of the wing to fuselage joint.
For this reason, this Airworthiness Directive (AD) requires
repetitive detailed visual inspections at the forward and aft wing
links and wing link attachment bolts for signs of corrosion,
replacement of corroded nuts and bolts and repair of any defects.
The MRBR and CPCP will be amended to include the repeat
inspections.
Actions and Compliance
(f) Unless already done, do the following actions: Before
accumulating 48 months on the wing link since new, or within 48
months of a wing link being repaired in accordance with a BAE
Systems (Operations) Limited or European Aviation Safety Agency
(EASA) approved repair scheme, or within 24 months after the
effective date of this AD, whichever occurs latest, and thereafter
at intervals not to exceed 48 months, inspect the wing links in
accordance with paragraph 2.C. of BAE Systems (Operations) Limited
Inspection Service Bulletin ISB.53-203, dated May 7, 2007 (``the
service bulletin'').
(1) If any corrosion is found on bolts or nuts, replace the
affected bolts and nuts with airworthy parts before next flight in
accordance with the service bulletin.
(2) If any corrosion to the wing links is found during an
inspection, repair before further flight in accordance with a method
approved in accordance with EASA (or its delegated agent).
