ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding an existing airworthiness directive (AD)
that applies to 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:

* * * [C]racks * * * in sections 13 to 18 of the fuselage between
rivets of longitudinal lap joints between frames 18 and 80 which
could affect the structural integrity of the fuselage if not
corrected.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.

DATES: This AD becomes effective November 16, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of November 16,
2011.

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 May 10, 2011 (76 FR
26962), and proposed to supersede AD 90-01-10, Amendment 39-6448 (55 FR
261, January 4, 1990). That NPRM proposed to correct an unsafe
condition for the specified products. The MCAI states:

This Airworthiness Directive (AD) is issued in order to prevent
cracks development in sections 13 to 18 of the fuselage between
rivets of longitudinal lap joints between frames 18 and 80 which
could affect the structural integrity of the fuselage if not
corrected.
This new AD:

--Retains the requirements of DGAC AD 1989-061-092(B)R4 [which
corresponds to FAA AD 90-01-10 (55 FR 261, January 4, 1990)], which
is cancelled;
--Takes into account a new inspection program as detailed in AIRBUS
Service Bulletins (SB) A300-53-0211 Revision 7, which will allow
A300 aircraft to reach the Limit of Validity (LOV).

This AD has been republished to correctly refer to SB A300-53-
0211 in Note 2 of the Compliance section.

The inspection program consists of repetitive detailed inspections
for disbonding and cracking of the fuselage inner doubler; eddy current
and ultrasonic inspections of the fuselage longitudinal lap joints for
cracking; and repair if necessary (i.e., repairing any cracking or
disbonding, or 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 received no comments on the NPRM (76 FR 26962, May 10,
2011) or on the determination of the cost to the public.

Clarification of Service Bulletin References

Paragraphs (h)(1) and (j)(1) of the NPRM (76 FR 26962, May 10,
2011) refer to Airbus Mandatory Service Bulletin A300-53-0211 as the
service information for airplanes on which an inspection of the
longitudinal lap joints has been done. For clarity, we have revised the
paragraphs to refer to the latest service bulletin revision and,
therefore, we have revised paragraphs (h)(1) and (j)(1) of this AD to
refer to Airbus Mandatory Service Bulletin A300-53-0211, Revision 07,
dated December 1, 2006.
Paragraphs (l)(1), (1)(2), (m)(1), (m)(2), (n)(1), (n)(2), (o)(1),
and (o)(2) of the NPRM (76 FR 26962, May 10, 2011) refer to Airbus
Service Bulletin A300-53-229 for the definition of ``major'' and
``minor'' disbonding. For clarity, we have revised the paragraphs to
refer to the latest service bulletin revision and, therefore, we have
revised paragraphs (l)(1), (1)(2), (m)(1), (m)(2), (n)(1), (n)(2),
(o)(1), and (o)(2) of this AD to refer to Airbus Service Bulletin A300-
53-229, Revision 5, dated April 8, 1997.

Conclusion

We reviewed the available data and determined that air safety and
the public interest require adopting the AD with the changes described
previously. We determined that these changes will not increase the
economic burden on any operator or increase the scope of the AD.

[[Page 63178]]

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 5 products of U.S.
registry.
We estimate that it will take about 3,735 work-hours per product to
comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Based on these figures, we estimate the cost
of the AD on U.S. operators to be $1,587,375, or $317,475 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; 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 (76 FR 26962, May 10, 2011),
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:
(1) Although the MCAI or service information allows further
flight after cracks are found during compliance with the required
action, this AD requires that you repair the crack(s) before further
flight.
(2) The MCAI or service information does not include enforceable
compliance times for certain actions; however, this AD requires that
those actions be done at the enforceable times specified in this AD.
(3) Although the MCAI or service information tells you to submit
information to the manufacturer, paragraph (p) of this AD specifies
that such submittal is not required.

Other FAA AD Provisions

(q) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, FAA, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19. In accordance with 14 CFR 39.19, send your request to your
principal inspector or local Flight Standards District Office, as
appropriate. If sending information directly to the International
