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 2018-0038, dated February 7, 2018 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A320-214, -251N, and -271N airplanes. The MCAI states:

    During a periodic check on the final assembly line, a 
dynamometric key, previously used for installing the cargo fire 
extinguishing bottle system, was found out of tolerance. As a 
consequence, an incorrect torque value may have been applied to the 
screws maintaining the fire extinguishing bottle in place. Vibration 
during normal operation of the aeroplane could further loosen these 
screws.
    This condition, if not detected and corrected, could lead to 
disconnection of a cargo fire extinguishing bottle, possibly 
resulting in loss of the fire protection system in the lower deck 
cargo compartment.
    Prompted by this finding, Airbus issued [Alert Operators 
Transmission] AOT A26N003-16 (later revised) to provide

[[Page 10359]]

instructions to apply the correct torque value(s).
    For the reason described above, this [EASA] AD requires a one-
time inspection of the screws of each cargo fire extinguishing 
bottle installation and, depending on findings, replacement of 
screws and re-installation of the system.

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0164.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Alert Operators Transmission A26N003-16, Revision 
01, dated June 12, 2017. The service information describes procedures 
for a general visual inspection for any damaged bolt and nut in each 
cargo fire extinguishing bottle installation, and replacement of all 
damaged bolts and nuts. 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 rule because of 
the possibility of loss of the fire protection system in the lower deck 
cargo compartment. 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-2018-0164; Product 
Identifier 2018-NM-026-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 2 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs

                                         hour = $85.
----------------------------------------------------------------------------------------------------------------

    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.

(d) Subject

    Air Transport Association (ATA) of America Code 26, Fire 
Protection.

(e) Reason

    This AD was prompted by a report that a dynamometric key, 
previously used for installing the cargo fire extinguishing bottle 
system, was out of tolerance. As a result, an incorrect torque value 
may have been applied to the bolts maintaining the fire 
extinguishing bottle in place. We are issuing this AD to detect and 
correct damaged bolts in the cargo fire extinguishing bottle system, 
which could lead to disconnection of a cargo fire extinguishing 
bottle, possibly resulting in loss of the fire protection system in 
the lower deck cargo compartment.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection and Corrective Actions

    Within 30 days after the effective date of this AD: Do a general 
visual inspection for any damaged bolt and nut in each cargo fire 
extinguishing bottle installation in accordance with the 
instructions in Airbus Alert Operators Transmission A26N003-16, 
Revision 01, dated June 12, 2017.
    (1) If any damaged bolt or nut is detected, before further 
flight, replace all damaged bolts and nuts, in accordance with the 
instructions in Airbus Alert Operators Transmission A26N003-16, 
Revision 01, dated June 12, 2017.
    (2) If no damage is detected, before further flight, reinstall 
the bolts and nuts, in accordance with the instructions in Airbus 
Alert Operators Transmission A26N003-16, Revision 01, dated June 12, 
2017.
    Note 1 to paragraph (g) of this AD: No credit will be provided 
for accomplishment of the actions in the original issue of Airbus 
Alert Operators Transmission A26N003-16 because the torque values 
were incorrect.
