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 2018-0058, dated March 14, 2018 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A350-941 airplanes. The MCAI states:

    Occurrences have been reported by Airbus A350 operators of 
malfunctions of Station Position Pick-Off Units (SPPU). 
Investigations indicated that internal wiring failures occurred due 
to water ingress via certain electrical connectors, inducing 
subsequent icing during flight.
    This condition, if not detected and corrected, could lead to 
hidden sensor signal drift (at flap station 3) which, in combination 
with an independent failure of a flap down drive disconnect, might 
lead to in-flight detachment of the outer flap surface, possibly 
resulting in damage to the aeroplane, and/or injury to persons on 
the ground.
    Airbus determined that the SPPU calibration test can highlight 
all hidden faults, but this test is only scheduled after removal/
installation of the equipment. Consequently, to address this 
potential unsafe condition, Airbus issued the SB [Service Bulletin 
A350-27-P021, dated February 13, 2018], providing instructions to 
accomplish the SPPU calibration test at regular intervals.
    For the reason described above, this [EASA] AD requires 
repetitive SPPU calibration test and, depending on findings, 
accomplishment of applicable corrective action(s) [applying 
corresponding airplane fault isolation].
    Pending the results of the on-going investigation, this [EASA] 
AD is still considered to be an interim measure and further [EASA] 
AD action may follow.

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0269.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A350-27-P021, dated February 13, 
2018. The service information describes performing repetitive SPPU 
calibration tests, and applying the corresponding airplane fault 
isolation if necessary. 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 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 the same 
type design.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this

[[Page 15049]]

rule because malfunctions of the SPPU and failures of the internal 
wiring due to water ingress via certain electrical connectors can 
induce icing, which under certain conditions, could lead to in-flight 
detachment of the outer flap surface, and consequent damage to the 
airplane. Therefore, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in fewer 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-2018-0269; Product 
Identifier 2018-NM-051-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 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 Compliances

    We estimate that this AD affects 6 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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 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.
