SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2018-0213, dated October 1, 2018 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus SAS 
Model A350-941 and -1041 airplanes. The MCAI states:

    A technical issue was detected on the inboard aileron electro-
hydrostatic actuators, causing potential erroneous monitoring of 
those actuators. Consequently, in-flight loss of inboard aileron 
control may occur, which, due to the resulting drag, would lead to 
increased fuel consumption.
    This condition, if not corrected, and if combined with one 
engine inoperative, could result in reduced control or performance 
of the aeroplane.
    To address this potential unsafe condition, Airbus issued the 
AFM [airplane flight manual] TR [temporary revision] and Flight 
Operations Transmission (FOT) 999.0062/18, informing operators that 
Airbus provides two different Airbus Temporary Quick Changes (ATQC) 
to the Electronic Centralized Aircraft Monitoring (ECAM), depending 
on the installed FWS [flight warning system] standard, either STD 
S4/2.0 or STD S5/2.2, as applicable, and issued the applicable SB 
[service bulletin] accordingly, providing modification instructions.
    For the reasons described above, this [EASA] AD requires 
amendment of the applicable AFM and installation of ATQC V4, 
followed by ECAM Temporary Change (ETC) activation, to update the 
procedures related to inboard aileron fault operations.
    This AD is considered to be an interim action and further AD 
action may follow.

    You may examine the MCAI on the internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2018-
0908.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus A350 Temporary Revision (TR) 113, Issue 
1.0, dated July 27, 2018, which provides updated procedures related to 
inboard aileron fault operations. 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.

[[Page 55618]]

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 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 the same 
type design.

Requirements of This AD

    This AD requires revising the Abnormal Procedures section of the 
AFM, as specified in the service information described previously.

Difference Between This AD and the MCAI

    In addition to the AFM revision, the MCAI requires installing two 
different ATQCs to the ECAM. We are considering requiring the 
installation of the ATQCs, but the planned compliance time for these 
actions would allow enough time to provide notice and opportunity for 
prior public comment on the merits of the installations.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because erroneous monitoring of the inboard aileron electro-hydrostatic 
actuators could result in in-flight loss of inboard aileron control, 
consequent increased fuel consumption due to the resulting drag, and 
reduced control or performance of the airplane if one engine is also 
inoperative. Therefore, we find good cause that notice and opportunity 
for prior public comment are impracticable. In addition, for the reason 
stated above, we find that good cause exists for making this amendment 
effective in less than 30 days.

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-2018-0908; Product 
Identifier 2018-NM-136-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 based on 
those comments.
    We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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 11 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

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 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

    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.

2018-22-13 Airbus SAS: Amendment 39-19486; Docket No. FAA-2018-0908; 
Product Identifier 2018-NM-136-AD.

(a) Effective Date

    This AD becomes effective November 23, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus SAS Model A350-941 and -1041 
airplanes, certificated in any category, except those on which the 
modifications specified in paragraph (c)(1) or (c)(2) of this AD, as 
applicable, have been embodied in production.
    (1) Airbus modifications 113759 and 113758.
    (2) Airbus modifications 113760 and 113758.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
controls.

(e) Reason

    This AD was prompted by a technical issue detected on the 
inboard aileron electro-hydrostatic actuators that caused potential 
erroneous monitoring of those actuators. We are issuing this AD to 
address possible in-flight loss of inboard aileron control, 
consequent increased fuel consumption due to the resulting drag, and 
reduced control or performance of the airplane if one engine is also 
inoperative.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Revision of the Airplane Flight Manual (AFM)

    Within 30 days after the effective date of this AD, revise the 
Abnormal Procedures section of the AFM to include the information in 
Airbus A350 Temporary Revision (TR) 113, Issue 1.0, dated July 27, 
2018, which introduces updated procedures related to inboard aileron 
fault operations. This may be done by inserting a copy of TR 113, 
Issue 1.0, dated July 27, 2018, into the AFM. When TR 113, Issue 
1.0, dated July 27, 2018, has been included in general revisions of 
the AFM, the general revisions may be inserted into the AFM, 
provided the relevant information in the general revisions is 
identical to that in TR 113, Issue 1.0, dated July 27, 2018, and the 
TR may be removed. Operate the airplane according to the procedures 
in TR 113, Issue 1.0, dated July 27, 2018. In case any discrepancy 
is identified between procedures displayed on the electronic 
centralized aircraft monitoring (ECAM) and procedures stated in the 
applicable AFM, the AFM procedures prevail.

(h) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the
