SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Airbus SAS Model 
A330-200 Freighter, A330-200, and A330-300 series airplanes. The NPRM 
published in the Federal Register on August 10, 2018 (83 FR 39633). The 
NPRM was prompted by a revision of a certain ALI document, which 
specifies new or more restrictive maintenance instructions and 
airworthiness limitations, and a determination that those maintenance 
instructions and airworthiness limitations are necessary. The NPRM 
proposed to require revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
maintenance instructions and airworthiness limitations.
    We are issuing this AD to address fatigue cracking, damage, and 
corrosion in principal structural elements; such fatigue cracking, 
damage, and corrosion 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 AD 
2018-0068, dated March 26, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus SAS Model A330-200 
Freighter, A330-200, and A330-300 series airplanes. The MCAI states:

    The airworthiness limitations for Airbus A330 and A340 
aeroplanes, which are approved by EASA, are currently defined and 
published in the A330 and A340 [Airworthiness Limitations Section] 
ALS document(s). The Damage Tolerant Airworthiness Limitation Items 
(DT ALI) are specified in the ALS Part 2. These instructions have 
been identified as mandatory actions for continued airworthiness.
    Failure to comply with these instructions could result in an 
unsafe condition [i.e., fatigue cracking, damage, and corrosion in 
principal structural elements] which could result in reduced 
structural integrity of the airplane.
    Previously, EASA issued AD 2016-0152 [which corresponds to FAA 
AD 2017-19-13, Amendment 39-19043 (82 FR 43837, September 20, 2017) 
(``AD 2017-19-13'')] for A330 and A340 aeroplanes to require 
accomplishment of all maintenance tasks as described in ALS Part 2 
Revision 01 (A330 aeroplanes) and Revision 02 (A340 aeroplanes).
    Since that [EASA] AD was issued, Airbus published Revision 02 of 
the ALS Part 2 for A330 aeroplanes, including new and/or more 
restrictive items.
    For the reason described above, this [EASA] AD takes over the 
requirements from EASA AD 2016-0152 for A330 aeroplanes, and 
requires accomplishment of all maintenance tasks as described in the 
ALS. EASA AD 2016-0152 has been revised accordingly, removing A330 
aeroplanes from the Applicability.

    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-2018-
0639.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comment received on the 
NPRM and the FAA's response to that comment.

Request To Clarify or Remove Previously Approved Alternative Method of 
Compliance (AMOC)

    American Airlines requested that we clarify the applicability of 
the AMOC approved in letter AIR-676-18-111 R1, dated January 29, 2018, 
or remove the previously approved AMOC from the proposed AD. The 
commenter stated that, as currently written, paragraph (j)(1)(ii) of 
the proposed AD is confusing because it states that the AMOC approved 
in letter AIR-676-18-111 R1, dated January 29, 2018, previously 
approved for AD 2017-19-13, would still be approved for the 
corresponding provisions of the final rule. The commenter explained 
that this AMOC is limited to a specific organization and is not 
applicable to all operators.
    We agree with the commenter's request for the reasons provided by 
the commenter. AMOC letter AIR-676-18-111 R1, dated January 29, 2018, 
was issued specifically to Singapore Technologies Aerospace Limited and 
is not a global AMOC. We have revised paragraph (j)(1)(ii) of this AD 
to clarify that the AMOC granted in letter AIR-676-18-111 R1, dated 
January 29, 2018, is approved as an AMOC for Model A330-300 series 
airplanes modified from a passenger to freighter configuration under 
the provisions of FAA Supplemental Type Certificate ST04038NY.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this final rule with the change described previously and minor 
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued Airbus A330 Airworthiness Limitations Section 
(ALS) Part 2--Damage Tolerant Airworthiness Limitation Items (DT-ALI), 
Revision 02, Issue 2, dated November 22, 2017. This service information 
describes maintenance instructions and airworthiness limitations 
applicable to the DT-ALI. 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 105 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:
    We have determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although we recognize that this number may vary from operator to 
operator. In the past, we have estimated that this action takes 1 work-
hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), we have 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, we estimate the total cost per operator 
to be $7,650 (90 work-hours x $85 per work-hour).

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

[[Page 60758]]

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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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.
