Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2010-0644; Directorate Identifier 2009-NM-204-AD;
Amendment 39-16466; AD 2010-21-06]
RIN 2120-AA64
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.

FAA AD Differences
Note 1: This AD differs from the MCAI and/or service
information as follows: No differences.
Other FAA AD Provisions
(i) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
has the authority to approve AMOCs for this AD, if requested using
