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 
2018-0110, dated May 18, 2018 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Airbus Model A320-271N airplanes, and Model 
A321-271N, -271NX, -272N, and -272NX airplanes. The MCAI states:

    During certification test flights of an A320-271N aeroplane, it 
has been identified that, when operated at low speed and high engine 
thrust, the tested engine did not re-start in case of a fuel 
interruption shorter than 5 seconds. Investigation revealed that 
this was due to the software logic implemented in the FADEC EEC of 
affected A320 family models.
    This condition, if not corrected, could prevent restart of a 
shut down engine while operating in high power conditions [after a 
single or dual in-flight engine shutdown].
    To address this potentially unsafe condition, software (SW) 
standard FCS4.4 for the FADEC EEC has been developed, and Airbus 
published the SB [Airbus Service Bulletin A320-73-1128, Revision 01, 
dated May 17, 2018] providing modification instructions.
    For the reasons described above, this [EASA] AD requires 
modification of aeroplanes by [replacing the affected FADEC EECs or 
by] installation of this FADEC EEC SW [software] standard [and re-
identification of the affected FADEC EECs].

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0492.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-73-1128, Revision 01, dated 
May 17, 2018. This service information describes procedures for 
replacing affected FADEC EECs and for installing software standard 
FCS4.4 and re-identifying affected FADEC EECs. 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

[[Page 24655]]

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 these 
same type designs.

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 a 
FADEC EEC software defect might prevent restart of an engine after a 
single or dual in-flight engine shutdown under certain conditions. 
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-2018-0492; Product 
Identifier 2018-NM-083-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 16 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 7 work-hours x $85 per hour             (1)   Up to $595..........  Up to $9,520.
 = Up to $595.
----------------------------------------------------------------------------------------------------------------
1 We have received no definitive data that would enable us to provide cost estimates for parts needed to comply
  with the 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.
