AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
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.

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 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 (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
Branch, send it to ATTN: Dan Rodina, Aerospace Engineer,
