SUPPLEMENTARY INFORMATION: 

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0256, dated November 28, 2018 
(``EASA AD 2018-0256'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus SAS Model A320-214, A320-232, A320-233, 
A321-211 and A321-231 airplanes. The MCAI states:

    During acceptance test of a RAT actuator P/N [part number] 
764711C at the manufacturer's facility, it failed to extend. 
Investigation results revealed that the actuator outer cylinder had 
not been properly de-burred in accordance with the manufacturing 
specifications. This caused blockage of the hydraulic circuit by 
metallic parts, preventing the RAT from extending.
    This condition, if not corrected, could lead to failure of RAT 
deployment when required, possibly resulting in reduced control of 
the aeroplane.
    To address this potential unsafe condition, Airbus issued the SB 
[Airbus Service Bulletin A320-29-1175, Revision 01, dated February 
16, 2018], identifying the affected parts and providing instructions 
for replacement, and Hamilton Sundstrand, manufacturer of the RAT 
actuator, issued the repair SB [UTC

[[Page 67681]]

Aerospace Systems Service Bulletin ERPS08A-29-6, dated August 29, 
2016] providing instructions for repair and reidentification.
    For the reasons described above, this [EASA] AD requires 
replacement of the affected parts with serviceable parts.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2018-0256 describes procedures for replacing affected RAT 
actuators with serviceable RAT actuators. This material 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, and it is publicly available through the EASA 
website.

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 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 EASA AD 
2018-0256 described previously. This AD also requires sending the 
inspection results to Airbus SAS.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA worked with Airbus and EASA to develop a process to 
use certain EASA ADs as the primary source of information for 
compliance with requirements for corresponding FAA ADs. As a result, 
EASA AD 2018-0256 will be incorporated by reference in the FAA final 
rule. This AD would, therefore, require compliance with the provisions 
specified in EASA AD 2018-0256, except for any differences identified 
as exceptions in the regulatory text of this AD. Service information 
specified in EASA AD 2018-0256 that is required for compliance with 
EASA AD 2018-0256 will be available on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
1065 after the FAA final rule is published.

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 failure to deploy the RAT during certain emergency conditions 
for generation of hydraulic or electrical power may result in reduced 
control of the airplane. Therefore, we find good cause that notice and 
opportunity for prior public comment are impracticable. In addition, 
for the reasons 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-2018-1065; Product 
Identifier 2018-NM-170-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 7 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
11 work-hours x $85 per hour = $935..........................              $0             $935           $6,545
----------------------------------------------------------------------------------------------------------------


                Estimated Costs of On-Condition Actions *
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
17 work-hours x $85 per hour = $1,445.              $0           $1,445
------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    We estimate that it would take about 1 work-hour per product to 
comply with the on-condition reporting requirement in this AD. The 
average labor rate is $85 per hour. Based on these figures, we estimate 
the cost of reporting the replacement 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

[[Page 67682]]

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 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.
