Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2019-0059, dated March 20, 2019 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for Airbus SAS Model A330-200 Freighter, 
A330-200, and A330-300 series airplanes. The MCAI states:

    The airworthiness limitations for Airbus A330 aeroplanes, which 
are approved by EASA, are currently defined and published in the 
A330 [Airworthiness Limitations Section] ALS document. 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.
    Previously, EASA issued AD 2018-0068 [which corresponds to FAA 
AD 2018-24-04, Amendment 39-19508 (83 FR 60756, November 27, 2018) 
(``AD 2018-24-04'')] for A330 aeroplanes to require accomplishment 
of all maintenance tasks as described in ALS Part 2 Revision 02.
    Since that [EASA] AD was issued, Airbus published Revision 03 of 
the ALS Part 2 for A330 aeroplanes, including new and/or more 
restrictive items.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2018-0068, which is superseded, and requires 
accomplishment of the actions specified in the ALS.

    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-2019-
0843.

Relationship Between Proposed AD and Other ADs

    This NPRM does not propose to supersede AD 2018-24-04 or AD 2017-
19-13, Amendment 39-19043 (82 FR 43837, September 20, 2017) (``AD 2017-
19-13''). Rather, the FAA has determined that a stand-alone AD is more 
appropriate to address the changes in the MCAI. This proposed AD would 
require revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. Accomplishment of the proposed actions would then 
terminate all requirements of AD 2018-24-04 and AD 2017-19-13.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus A330 Airworthiness Limitations Section 
(ALS) Part 2--Damage Tolerant Airworthiness Limitation Items (DT-ALI), 
Revision 03, dated October 15, 2018, as supplemented by Airbus A330 
Airworthiness Limitations Section (ALS) Part 2--Damage Tolerant 
Airworthiness Limitation Items (DT-ALI), Variation 3.1, dated January 
18, 2019, which describes mandatory maintenance tasks that operators 
must perform at specified intervals. This service information describes 
airworthiness limitations for certification maintenance requirements 
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.

FAA's Determination

    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

[[Page 29430]]

Design Authority, the FAA has been notified of the unsafe condition 
described in the MCAI and service information referenced above. The FAA 
is proposing this AD because we evaluated all the relevant information 
and determined the unsafe condition described previously is likely to 
exist or develop on other products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(j)(1) of this proposed AD.

Differences Between This Proposed AD and the MCAI or Service 
Information

    The MCAI specifies that if there are findings from the 
airworthiness limitations section (ALS) inspection tasks, corrective 
actions must be accomplished in accordance with [Airbus] maintenance 
documentation. However, this proposed AD does not include that 
requirement. Operators of U.S.-registered airplanes are required by 
general airworthiness and operational regulations to perform 
maintenance using methods that are acceptable to the FAA. The FAA 
considers those methods to be adequate to address any corrective 
actions necessitated by the findings of ALS inspections required by 
this proposed AD.

Costs of Compliance

    The FAA estimates that this proposed AD affects 107 airplanes of 
U.S. registry. We estimate the following costs to comply with this 
proposed AD:
    The agency determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. In the past, the agency has estimated that this action 
takes 1 work-hour per airplane. Since operators incorporate maintenance 
or inspection program changes for their affected fleet(s), the agency 
has determined that a per-operator estimate is more accurate than a 
per-airplane estimate. Therefore, the agency estimates 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.
    The FAA is 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 proposed 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

    The FAA 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. Will not affect intrastate aviation in Alaska; and
    3. 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.
