ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2009-11-08, which applied to certain Airbus Model A330-202, -223, -243, -301, -322, and -342 airplanes. AD 2009-11-08 required repetitive special detailed (high frequency eddy current) inspections to detect cracking of the keel beam fitting horizontal flange edge at a certain frame (FR) on the left- and right-hand sides of the fuselage, and repair if necessary. This AD was prompted by a new fatigue and damage tolerance evaluation that concluded the current inspection thresholds and intervals had to be modified. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. We are issuing this AD to address the unsafe condition on these products.
DATES: This AD becomes effective May 15, 2018.

SUPPLEMENTARY INFORMATION:
Discussion
We issued AD 2009-11-08, Amendment 39-15918 (74 FR 25404, May 28, 2009) (``AD 2009-11-08''), which applied to certain Airbus Model A330-
202, -223, -243, -301, -322, and -342 airplanes. AD 2009-11-08 was prompted by reports of cracks on the left- and right-hand sides between the crossing area of the keel angle fitting and the front spar of the center wing box. AD 2009-11-08 required a special detailed (high frequency eddy current) inspection to detect cracking of the keel beam fitting horizontal flange edge at FR40 on the left- and right-hand sides of the fuselage, and repair if necessary. We issued AD 2009-11-08 to detect and correct cracking on the left- and right-hand sides, between the crossing area of the keel angle fitting and the front spar of the center wing box, which if not corrected, could affect the structural integrity of the airplane.
Since we issued AD 2009-11-08, a new fatigue and damage tolerance evaluation was conducted by the manufacturer. It was concluded that, due to airplane utilization, the current inspection thresholds and intervals had to be modified.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2013-0247, dated October 10, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus Model A330-202, -223, -
243, -301, -322, and -342 airplanes. The MCAI states:
During the A330 and A340 aeroplane fatigue test, cracks appeared on the right and left sides between the crossing area of the keel angle fitting and the front spar of the Centre Wing Box (CWB). Several modifications were introduced in the fleet in the area of frame (FR) 40 keel angle assembly in order to prevent these cracks. However, the new design caused interference between one fastener and the keel angle which was corrected by further local reprofiling of the keel angle horizontal flange.
This condition, if not detected and corrected, could result in reduced structural integrity of the area.
Prompted by these findings, EASA issued AD 2008-0213 which corresponds to FAA AD 2009-11-08 to require accomplishment of repetitive special detailed inspection on the horizontal flange of the keel beam in the area of first fastener hole aft of FR40 and, depending on findings, accomplishment of a repair.
Since that EASA AD was issued, a new fatigue and damage tolerance evaluation was conducted by Airbus. It was concluded that, due to aeroplane utilisation, the current inspection thresholds and intervals had to be modified.
For the reason described above, this EASA AD retains the requirements of EASA AD 2008-0213, which is superseded, and redefines the thresholds and intervals.
You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0305.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
FAA's Determination of the Effective Date
Since there are currently no domestic operators of this product, we find good cause that notice and opportunity for prior public comment are unnecessary. In addition, for the reason(s) stated above, we find that good cause exists for making this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2018-0305; Product Identifier 2013-NM-226-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance
Currently, there are no affected U.S.-registered airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition, and doing the actions specified in those instructions. Based on the actions specified in the MCAI AD, we are providing the following cost estimates for an affected airplane that is placed on the U.S. Register in the future:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection new action............... 9 work-hours x $85 per $0 $765 $0
hour = $765.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in the MCAI AD.
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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division.
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 that 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
