We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-500 and -600 series airplanes. This AD was prompted by a quality control review on the final assembly line, which determined that the wrong aluminum alloy was used to manufacture several structural parts. This AD requires a one-time eddy current conductivity measurement of certain cabin and cargo compartment structural parts to determine if an incorrect aluminum alloy was used, and replacement of any affected part with a serviceable part. We are issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and 
Model A340-500 and -600 series airplanes. This AD was prompted by a 
quality control review on the final assembly line, which determined 
that the wrong aluminum alloy was used to manufacture several 
structural parts. This AD requires a one-time eddy current conductivity 
measurement of certain cabin and cargo compartment structural parts to 
determine if an incorrect aluminum alloy was used, and replacement of 
any affected part with a serviceable part. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective October 2, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 2, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to certain Airbus 
Model A330-200, -200 Freighter, and -300 series airplanes; and Model 
A340-500 and -600 series airplanes. The SNPRM published in the Federal 
Register on May 19, 2017 (82 FR 22907) (``the SNPRM''). We preceded the 
SNPRM with a notice of proposed rulemaking (NPRM) that published in the 
Federal Register on June 21, 2016 (81 FR 40201) (``the NPRM''). The 
NPRM proposed to require a one-time eddy current conductivity 
measurement of certain cabin and cargo compartment structural parts to 
determine if an incorrect aluminum alloy was used, and replacement of 
any affected part with a serviceable part. The NPRM was prompted by a 
quality control review on the final assembly line, which determined 
that the wrong aluminum alloy was used to manufacture several 
structural parts. The SNPRM proposed to require new inspection 
locations for certain airplanes, and removing incorrect part numbers. 
We are issuing this AD to detect and replace structural parts made of 
an incorrect aluminum alloy. This condition could result in reduced 
structural integrity of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0021, dated February 8, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A330-200, -200 Freighter, and -300 series airplanes; and Model A340-500 
and -600 series airplanes. The MCAI states:

    Following an Airbus quality control review on the final assembly 
line, it was discovered that wrong aluminum alloy was used to 
manufacture several structural parts.
    This condition, if not detected and corrected, could reduce the 
structural integrity of the aeroplane.
    To address this potential unsafe condition, Airbus published 
[Service Bulletin] (SB) A330-53-3261, SB A330-53-3262, and SB A340-
53-5072, as applicable to aeroplane type/model, to provide 
instructions to identify the affected parts. Consequently, EASA 
issued AD 2015-0206 to require a one-time special detailed 
inspection (SDI) [eddy current conductivity measurements] of certain 
cabin and/or cargo compartment parts for material identification 
and, depending on findings, replacement with serviceable parts.
    Since that [EASA] AD was issued, Airbus identified that the list 
of affected structural parts in SB A330-53-3261 was incorrect. 
Prompted by these findings, Airbus issued SB A330-53-3261 Revision 
01 to introduce the new locations to be inspected and remove other 
parts not affected.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2015-0206, which is superseded, and expands 
the locations to be inspected.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
7264.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM or on the determination 
of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information:
     Airbus Service Bulletin A330-53-3261, Revision 01, 
including Appendixes 01, 02, and 03, dated November 10, 2016.
     Airbus Service Bulletin A330-53-3262, including Appendixes 
01 and 02, dated June 23, 2015.

[[Page 40671]]

     Airbus Service Bulletin A340-53-5072, including Appendixes 
01 and 02, dated June 23, 2015.
    This service information describes procedures for a one-time eddy 
current conductivity measurement of certain cabin and cargo compartment 
structural parts to determine if an incorrect aluminum alloy was used, 
and replacement of any affected part with a serviceable part. These 
documents are distinct because they apply to different parts on 
different airplanes. This service information is reasonably available 
because the interested parties have access to it through their normal 
course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 37 airplanes of U.S. registry.
    We also estimate that it takes about 17 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD on U.S. operators to be $53,465, or $1,445 per product.
    In addition, we estimate that any on-condition repairs take about 
45 work-hours and will require parts costing $0, for a cost of $3,825 
per product. We have no way of determining the number of aircraft that 
might need these repairs.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all available costs in our 
cost estimate.

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.
