Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2019-0049, dated March 11, 2019 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A330-200, -200F, 
and -300 series airplanes. The MCAI states:

    The airworthiness limitations for the Airbus A330 aeroplanes, 
which are approved by EASA, are currently defined and published in 
the A330 ALS [airworthiness limitations section] documents. The 
airworthiness limitations applicable to the Certification 
Maintenance Requirements (CMR), which are approved by EASA, are 
published in the ALS.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    Previously, EASA issued AD 2016-0066 [corresponds to FAA AD 
2016-26-05, Amendment 39-18763 (82 FR 1170, January 5, 2017) (``AD 
2016-26-05'')] to require accomplishment of all maintenance tasks as 
described in A330 ALS Part 3 at Revision 05.
    Since that [EASA] AD was issued, Airbus published the ALS, as 
defined in this [EASA] AD, including new and/or more restrictive 
tasks.
    For the reasons described above, this [EASA] AD takes over the 
requirements for Airbus A330 aeroplanes from EASA AD 2016-0066 and 
requires accomplishment of the actions specified in the ALS.

    The unsafe condition is a safety-significant latent failure (that 
is not annunciated) that, in combination with one or more other 
specific failures or events could result in a hazardous or catastrophic 
failure condition. 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-2019-0523.

Relationship Between Proposed AD and AD 2016-26-05

    This NPRM does not propose to supersede AD 2016-26-05. 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 of the 
requirements of AD 2016-26-05.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus A330 Airworthiness Limitations Section 
(ALS) Part 3--Certification Maintenance Requirements (CMR), Revision 
06, dated October 15, 2018. The service information describes 
maintenance instructions and airworthiness limitations, including 
updated inspections and intervals, to be incorporated into the 
maintenance or inspection program. 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 a bilateral agreement with the State of 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 the agency 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 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.

[[Page 32663]]

Costs of Compliance

    The FAA estimates that this proposed AD affects 107 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:
    The FAA has 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 FAA 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 FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the FAA 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.
