ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by 
reports that electro-hydrostatic actuators (EHAs), installed on the 
inboard ailerons, elevators, and rudder, had degraded insulation 
resistance in the direct drive solenoid valve (DDSOV), due to incorrect 
sealing application. This AD requires a check of the insulation 
resistance of the DDSOV of each affected EHA and applicable corrective 
actions. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD becomes effective August 30, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 30, 
2018.

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 AD 
2018-0141, dated July 3, 2018 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Airbus SAS Model A350-941 and -1041 airplanes. 
The MCAI states:

    Occurrences were reported of EHA units that were returned to the 
manufacturer (MOOG Aircraft Group) with degraded insulation 
resistance in the direct drive solenoid valve (DDSOV). Investigation 
results revealed that moisture ingress, due to incorrect sealing 
application, had caused this degradation.
    This condition, if not detected and corrected, could lead to the 
DDSOV being unable to command or maintain the EHA in active mode, 
possibly resulting in reduced control of the aeroplane.
    Due to similarity of design, all five EHA positions could be 
affected, inboard aileron EHAs (Functional Item Number (FIN) 4CR1 
and FIN 4CR2), elevator EHAs (FIN 2CT1 and FIN 2CT2) and the rudder 
EHA (FIN 3CY). Prompted by these findings, MOOG Aircraft Group 
improved the manufacturing process to ensure adequate sealing 
capability of the DDSOV and issued the applicable SB [MOOG Aircraft 
Group Service Bulletins CA67001-27-05; CA67006-27-04; and CA67008-
27-04] providing a screening procedure. To address this potential 
unsafe condition, Airbus issued the AOT [Alert Operators 
Transmission A27P009-16] and the Airbus SB [Service Bulletin A350-
27-P020], providing instructions to restore the EHA to nominal 
performance.
    For the reasons described above, this [EASA] AD requires a one-
time insulation check of each affected EHA, and, depending on 
findings, accomplishment of applicable corrective action(s).

    Corrective actions include replacing or reidentifying affected 
EHAs. You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0709.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued Service Bulletin A350-27-P020, dated February 
22, 2018. This service information describes procedures for an 
insulation resistance check (detailed inspection) of the DDSOV of each 
affected EHA and applicable corrective actions.
    Moog Aircraft Group has issued Service Bulletin CA67001-27-05, 
dated February 21, 2018. This service information identifies affected 
EHAs for certain inboard ailerons and describes, among other actions, 
procedures for applicable corrective actions.
    Moog Aircraft Group has issued Service Bulletin CA67006-27-04, 
dated February 21, 2018. This service information identifies affected 
EHAs for certain elevators and describes, among other actions, 
procedures for applicable corrective actions.
    Moog Aircraft Group has issued Service Bulletin CA67008-27-04, 
dated February 21, 2018. This service information identifies affected 
EHAs for certain rudders and describes, among other actions, procedures 
for applicable corrective actions.
    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 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 accomplishing the actions specified in the service 
information described previously. This AD also requires sending the 
results of the check to AirbusWorld.

[[Page 40440]]

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 rule because the 
insulation resistance in the DDSOV can degrade to unsafe levels within 
three months, which could lead to the DDSOV being unable to command or 
maintain the EHA in active mode, possibly resulting in reduced control 
of the airplane. Therefore, we determined that notice and opportunity 
for public comment before issuing this AD are impracticable and that, 
for the same reason, 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-2018-0709; Product 
Identifier 2018-NM-100-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 Compliance

    We estimate that this AD affects 11 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                  Parts cost         Cost per product          Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 24 work-hours x $85 per hour =                $0  Up to $2,040.............  Up to $22,440.
 Up to $2,040.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
actions that would be required based on the results of any required 
actions. We have no way of determining the number of aircraft that 
might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
          Labor cost                Parts cost        Cost per product
------------------------------------------------------------------------
Up to 30 work-hours x $85 per   Up to $518,314...  Up to $520,864.
 hour = Up to $2,550.
------------------------------------------------------------------------

    We estimate that it would take about 1 work-hour per product to 
comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, we estimate the cost of 
reporting the check results on U.S. operators to be $85 per product.
    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all known costs in our cost 
estimate.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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:

[[Page 40441]]

    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.
