SUPPLEMENTARY INFORMATION: 

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0073, dated March 26, 2020 
(``EASA AD 2020-0073'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A318-111, -112, -121, and -122 
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, -
151N, -153N, and -171N airplanes; Model A320-211, -212, -214, -215, -
216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N 
airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -
232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, 
and -272NX airplanes. (Model A320-215 airplanes are not certified by 
the FAA and are not included on the U.S. type certificate data sheet; 
this AD therefore does not include those airplanes in the 
applicability.)
    This AD was prompted by a recent maintenance repair organization's 
report to Airbus of deviations from the acceptance test procedure for 
certain THSAs as specified in the Airbus component maintenance manual 
(CMM) after disassembly and reassembly of the THSA ball screw sub-
assembly. A deviation from the accepted test procedure affects, in 
particular, the verification of proper installation of the THSA ball 
screw in shop. Improper installation of the THSA ball screw jack 
compromises the fail safe design of the THSA that prevents the axial 
separation of the screw shaft. Subsequent missed inspections or testing 
regimes further compromise the fail safe design of the THSA. A 
compromised fail safe design of the THSA can result in a single failure 
of the THSA. The FAA is issuing this AD to address this unsafe 
condition, which can compromise fail safe design of the THSA, which may 
result in uncontrolled movement of the horizontal stabilizer as a 
result of a single failure, and consequent loss of control of the 
airplane. See the MCAI for additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0073 describes procedures for replacing affected THSAs 
with serviceable THSAs. 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.

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 the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this AD because the agency 
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 
2020-0073 described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially 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. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2020-0073 
is incorporated by reference in this final rule. This AD, therefore, 
requires compliance with EASA AD 2020-0073 in its entirety, through 
that incorporation, except for any differences identified as exceptions 
in the regulatory text of this AD. Using common terms that are the same 
as the heading of a particular section in the EASA AD does not mean 
that operators need comply only with that section. For example, where 
the AD requirement refers to ``all required actions and compliance 
times,'' compliance with this AD requirement is not limited to the 
section titled ``Required Action(s) and Compliance Time(s)'' in the 
EASA AD. Service information specified in EASA AD 2020-0073 that is 
required for compliance with EASA AD 2020-0073 is available on the 
internet at https://www.regulations.gov by searching for and locating 
Docket No. FAA-2020-0210.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C.) authorizes agencies to dispense with notice and comment 
procedures for rules when the agency, for ``good cause,'' finds that 
those procedures are ``impracticable, unnecessary, or contrary to the 
public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without seeking comment prior to the 
rulemaking. Similarly, Section 553(d) of the APA authorizes agencies to 
make

[[Page 18430]]

rules effective in less than thirty days, upon a finding of good cause.
    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 foregoing notice and comment prior to adoption of this rule 
because, as described in the Discussion section of this AD, improper 
installation of THSA ball screw jack compromises fail safe design of 
the THSA, which can result in uncontrolled movement of the horizontal 
stabilizer as a result of a single failure of the THSA, and consequent 
loss of control of the airplane. Given the significance of the risk 
presented by this unsafe condition, it must be immediately addressed.
    Accordingly, notice and opportunity for prior public comment are 
impracticable pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the 
reasons stated above, the FAA finds that good cause exists pursuant to 
5 U.S.C. 553(d) for making this amendment effective in less than 30 
days.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not precede it by notice and opportunity for 
public comment. The FAA invites 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-2020-0210; 
Product Identifier 2020-NM-045-AD'' at the beginning of your comments. 
The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. The FAA will 
consider all comments received by the closing date and may amend this 
AD based on those comments.
    The FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide. 
The FAA will also post a report summarizing each substantive verbal 
contact received about this AD.

Costs of Compliance

    The FAA estimates that this AD affects 89 airplanes of U.S. 
registry. The FAA estimates 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 13 work-hours x $85 per hour = Up               $0  Up to $1,105..............  Up to $98,345.
 to $1,105.
----------------------------------------------------------------------------------------------------------------

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.
    The FAA is 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.

Regulatory Findings

    The FAA 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, and
    (2) Will not affect intrastate aviation in Alaska.
