[Docket No. FAA-2016-7264; Directorate Identifier 2015-NM-185-AD]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt 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 proposed 
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 proposed AD would 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. We are proposing this AD to detect and replace structural parts 
made of incorrect aluminum alloy. This condition could result in 
reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by August 5, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0206, dated October 12, 2015 (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 issued 
Service Bulletin (SB) A330-53-3261, SB A330-53-3262, and SB A340-53-
5072, as applicable to aeroplane type, to provide instructions to 
identify the affected parts.

[[Page 40202]]

    For the reasons described above, this [EASA] AD requires 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.

    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.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service information:
     Airbus Service Bulletin A330-53-3261, including Appendixes 
01, 02, and 03, dated June 23, 2015.
     Airbus Service Bulletin A330-53-3262, including Appendixes 
01 and 02, dated June 23, 2015.
     Airbus Service Bulletin A340-53-5072, including Appendixes 
01 and 02, dated June 23, 2015.
    The 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. 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.

FAA's Determination and Requirements of This Proposed 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 and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 37 airplanes of U.S. 
registry.
    We also estimate that it would take about 11 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $34,595, or $935 
per product.
    In addition, we estimate that any on-condition repairs would take 
about 45 work-hours and would 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 proposed 
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.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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.
