[Docket No. FAA-2019-0667; Product Identifier 2019-NM-085-AD]
RIN 2120-AA64


Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus SAS Model A320-214, -216, -232, and -233 airplanes. 
This proposed AD was prompted by a report of undetected contacts 
between certain harnesses of the common fuel quantity indicating system 
and the center tank structure. This proposed AD would require 
modification of the fasteners for certain harness routings, as 
specified in a European Aviation Safety Agency (EASA) AD, which will be 
incorporated by reference. The FAA is proposing this AD to address the 
unsafe condition on these products.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0155, dated July 20, 2018 
(``EASA AD 2018-0155'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus SAS Model A320-214, -216, -232, and -233 
airplanes. The MCAI states:

    A Zonal Safety review identified previously undetected contacts 
between harnesses and the centre tank structure. Investigation 
determined that these contacts were introduced with a new harness 
routing upon installation of a common fuel quantity indicating 
system across A320 family aeroplanes (Airbus mod 155636).
    This condition, if not corrected, could create, in case of 
lightning strike with chafing present, an ignition source inside the 
centre fuel tank, possibly resulting in a fuel tank explosion and 
consequent loss of the aeroplane.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A320-92-1121 to provide instructions for 
modification of the harnesses.
    For the reason described above, this [EASA] AD requires 
modification of harnesses 17QT and 18QT of the common fuel quantity 
indicating system by introducing longer spacers and additional 
clamps.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2018-0155 describes procedures for modification of the 
fasteners for harness routings 17QT and 18QT.
    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 and Requirements of This Proposed AD

    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

[[Page 45691]]

described in the MCAI referenced above. The FAA is proposing this AD 
because the FAA evaluated all the relevant information and determined 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2018-0155 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 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 2018-0155 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with the 
provisions specified in EASA AD 2018-0155, through that incorporation, 
except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Service information specified in EASA AD 
2018-0155 that is required for compliance with EASA AD 2018-0155 will 
be available on the internet at http://www.regulations.gov by searching 
for and locating Docket No. FAA-2019-0667 after the FAA final rule is 
published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 5 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 
proposed 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.
    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.
    This proposed 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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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.
