14 CFR Part 39

[Docket No. FAA-2010-1274; Directorate Identifier 2010-NM-090-AD; 
Amendment 39-16687; AD 2011-10-06]

Airworthiness Directives; Airbus Model A310 Series Airplanes

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:

    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France AD 1992-106-132(B) * * * was issued to require a set of 
inspection and modification tasks which addressed JAR/FAR [Joint 
Aviation Regulation/Federal Aviation Regulation] 25-571 requirements 
related to damage-tolerance and fatigue evaluation of structure.
* * * * *

The unsafe condition is reduced structural integrity of the wings. We 
are issuing this AD to require actions to correct the unsafe condition 
on these products.

DATES: This AD becomes effective June 15, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 15, 
2011.

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 January 3, 2011 (76 
FR 50). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France AD 1992-106-132(B) original issue up to revision 7 was issued 
to require a set of inspection and modification tasks which 
addressed JAR/FAR [Joint Aviation Regulation/Federal Aviation 
Regulation] 25-571 requirements related to damage-tolerance and 
fatigue evaluation of structure.
    Following the Extended Design Service Goal activities as part of 
the Structure Task Group for the Airbus A310 program, EASA [European 
Aviation Safety Agency] published AD 2007-0053, which replaced DGAC 
France AD F-1992-106-132R7.
    Since the issuance of AD 2007-0053R1, the thresholds and the 
intervals of Airbus Service Bulletins (SB) A310-57-2050 and A310-57-
2064 have been updated.
    Consequently, this new [EASA] AD takes over the requirements of 
paragraphs 1.15 and 1.17 of EASA AD 2007-0053R1, which has been 
revised accordingly * * * and requires the accomplishment of Airbus 
SB A310-57-2048 at revision 01.

The unsafe condition is reduced structural integrity of the wings. The 
required actions are as follows, depending on airplane configuration:

    <bullet> Cold working of trellis boom drainage holes.
    <bullet> Repetitive detailed or rotating probe inspections for 
cracking in the drain holes on the lower skin panel in the center wing 
box between frames 42 and 46 and corrective actions if necessary. 
Corrective actions include repairing cracking and contacting the FAA or 
EASA for repair and doing the repair.
    <bullet> Repetitive eddy current inspections for cracking of the 
upper corner angle fitting and the vertical tee fitting at left and 
right frame 40, and corrective actions if necessary. Corrective actions 
include repairing, replacing the internal angle fitting, and contacting 
the FAA or EASA for repair and doing the repair.
    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 considered the comment received.

Request To Revise Paragraph Header

    An anonymous commenter requested that the paragraph reference in 
the paragraph header between table 5 and paragraph (k) of the NPRM be 
revised from ``paragraph (h)'' to ``paragraph (j)''. The commenter 
believed the intent was to reference paragraph (j) of the NPRM.
    We agree with the commenter's request. We have revised the 
paragraph header between table 5 and paragraph (k) of this AD.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the change described previously. We determined that this change 
will not

[[Page 27228]]

increase the economic burden on any operator or increase the scope of 
the AD.

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 44 products of U.S. registry. 
We also estimate that it will take about 137 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $512,380, or $11,645 per product.

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.
