SUPPLEMENTARY INFORMATION: 

Discussion

    On June 15, 2017, we issued AD 2017-13-05, Amendment 39-18935 (82 
FR 34251, July 24, 2017) (``AD 2017-13-05''), which applied to all 
Airbus Model A330-200, A330-300, A340-200, A340-300, A340-500, and 
A340-600 series airplanes. AD 2017-13-05 was prompted by the need for a 
modification that automatically detects failure of the ball-screw 
assembly. AD 2017-13-05 required an inspection, corrective actions if 
necessary, lubrication of the ball-nut, modification of the trimmable 
horizontal stabilizer actuator (THSA), and additional work for 
previously modified airplanes. For certain airplanes, AD 2017-13-05 
required installation of an electronic harness, terminating actions, 
and a ball-screw assembly inspection. We issued AD 2017-13-05 to detect 
and correct wear on the THSA, possibly resulting in damage to the ball-
screw and fail-safe nut, which could jam the THSA and result in reduced 
control of the airplane.
    Since we issued AD 2017-13-05, we have received reports indicating 
that affected parties could misinterpret the identity of applicable 
service information to use for the modification, due to the formatting 
of figure 2 to paragraphs (h) and (i) in the published version of AD 
2017-13-05. Since the published figure could result in a negative 
effect on compliance, we have determined that clarification of the 
formatting of the published figure is necessary.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2014-0219, dated September 29, 2014 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus Model A330 and Model A340 
series airplanes. (Model A330-223F and A330-243F airplanes were removed 
from AD 2017-13-05 to correspond with the MCAI.) The EASA AD is 
referenced in AD 2017-13-05. EASA has not revised its AD since the 
issuance of AD 2017-13-05.
    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-2017-
0813.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

FAA's Justification and Determination of the Effective Date

    We are superseding AD 2017-13-05 to clarify the formatting of a 
figure in the regulatory text of the published AD. No other changes 
have been made to AD 2017-13-05. Therefore, we determined that notice 
and opportunity for prior public comment are unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2017-0813; Product 
Identifier 2017-NM-109-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 33 airplanes of U.S. registry. 
This AD adds no new economic burden to AD 2017-13-05.
    We estimate that it takes about 68 work-hours per product to comply 
with the basic requirements of this AD. The average labor rate is $85 
per work-hour. Required parts would cost about $17,481 per product. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $764,808, or $23,260 per product.

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.
    This AD is issued in accordance with authority delegated by the 
Executive

[[Page 44909]]

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 to the Director 
of the System Oversight Division.

Regulatory Findings

    We determined that 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.
