14 CFR Part 39

[Docket No. FAA-2010-0644; Directorate Identifier 2009-NM-204-AD; 
Amendment 39-16466; AD 2010-21-06]

Airworthiness Directives; Airbus Model A300 B4-600 Series 
Airplanes, Model A300 B4-600R Series Airplanes, Model A300 C4-605R 
Variant F Airplanes, and Model A300 F4-600R Series Airplanes 
(Collectively Called A300-600 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:

    Within the framework of the A300-600 aircraft Service Life 
Extension programme (42,500 FC [flight cycles]), it has been 
concluded that a reinforcement of the junction of frame bases at 
FR48, FR49 and FR51 to FR53 is necessary to enable the aircraft to 
reach the Extended Service Goal (ESG).
    * * * [Failure of the frame base], if not corrected, could 
affect the structural integrity of the fuselage.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective November 12, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 12, 
2010.

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 July 1, 2010 (75 FR 
38061). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Within the framework of the A300-600 aircraft Service Life 
Extension programme (42,500 FC [flight cycles]), it has been 
concluded that a reinforcement of the junction of frame bases at 
FR48, FR49 and FR51 to FR53 is necessary to enable the aircraft to 
reach the Extended Service Goal (ESG).
    * * * [Failure of the frame base], if not corrected, could 
affect the structural integrity of the fuselage.
    For the reasons described above, this AD requires the 
reinforcement of the affected junction of frame bases.

Required actions include doing a dimensional measurement of the holes, 
and doing corrective actions if necessary; doing an eddy current 
inspection of the holes for cracking, and doing corrective actions if 
necessary; and doing cold expansion of the holes and installing 
fasteners. Corrective actions include contacting Airbus for repair 
instructions 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. The commenter supports the 
NPRM.

Change to Compliance Time Specified in Paragraph (h) of This AD

    We have revised paragraph (h) of this AD by adding the compliance 
time ``within 100 flight cycles after the effective date of this AD'' 
to the sentence ending with ``accomplish those instructions.'' We have 
evaluated the data and determined that adding this compliance time will 
not adversely affect safety.

Conclusion

    We reviewed the available data, including the comments 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 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 122 products of U.S. registry. 
We also estimate that it will take about 81 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $12,300 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $2,340,570, or $19,185 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.

corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated
