Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening 
of comment period.

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

SUMMARY: We are revising an earlier notice of proposed rulemaking 
(NPRM) for certain Airbus Model A330-200, -200 Freighter, and -300 
series airplanes; and Model A340-500 and -600 series airplanes. This 
action revises the NPRM by including new inspection locations for 
certain airplanes, and removing incorrect part numbers. We are 
proposing this airworthiness directive (AD) to address the unsafe 
condition on these products. Since these actions impose an additional 
burden over those proposed in the NPRM, we are reopening the comment 
period to allow the public the chance to comment on these proposed 
changes.

Discussion

    We issued an NPRM 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 
NPRM published in the Federal Register on June 21, 2016 (81 FR 40201) 
(``the NPRM''). 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 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 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.

[[Page 22908]]

    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.

Related Service Information Under 1 CFR Part 51

    We reviewed 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.
     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 distinct since it applies 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.

Comments

    We gave the public the opportunity to participate in developing the 
NPRM. We considered the comments received.

Request To Change Compliance Time

    American Airlines (AA) asked that we change the compliance time for 
the on-condition replacement specified in paragraph (h) of the proposed 
AD (in the NPRM) from ``before further flight'' to ``within 6 years 
after the effective date of the AD, or within 12 years from the 
aeroplane date of manufacture, whichever occurs first'' to correspond 
with the compliance time in the EASA AD. AA stated that this would 
provide more flexibility to operators in order to have a better plan to 
procure the parts and accomplish the replacement without extended 
downtime if the replacement parts are not immediately available after 
doing the inspection.
    We agree with the commenter for the reasons provided. We have 
changed the compliance time specified in paragraph (h) of this proposed 
AD accordingly.

Request To Correct Typographical Error

    AA asked that we correct a typographical error specified in the 
second box of Figure A-GFAAA, Sheet 02, ``Inspection Flowchart,'' of 
the service information identified in paragraphs (g)(2) and (g)(3) of 
the proposed AD (in the NPRM). AA stated that the conductivity 
measurement should specify Sigma 60 instead of Sigma 480.
    We agree that the conductivity measurement specified in the second 
box of the specified inspection flowchart is incorrect. We have added 
paragraph (i) to this proposed AD to specify this exception to the 
inspection flowchart in the service information. We have redesignated 
subsequent paragraphs accordingly.

Additional Changes to This Proposed AD

    As stated previously, we have revised this proposed AD to include 
new inspection locations for certain airplanes, and to remove incorrect 
part numbers from table 1 to paragraphs (g) and (h) of this proposed 
AD.

FAA's Determination and Requirements of This SNPRM

    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 the same 
type design.
    Certain changes described above expand the scope of the NPRM. As a 
result, we have determined that it is necessary to reopen the comment 
period to provide additional opportunity for the public to comment on 
this SNPRM.

Costs of Compliance

    We estimate that this proposed AD affects 37 airplanes of U.S. 
registry.
    We also estimate that it would take about 17 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 $53,465, or $1,445 
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.
