Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus SAS Model A318, A319, and A320 series airplanes; and Model A321-
111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and -271N 
airplanes. This AD was prompted by a revision of an airworthiness 
limitations document that specifies more restrictive maintenance 
requirements and airworthiness limitations. This AD requires revising 
the maintenance or inspection program, as applicable, to incorporate 
revised fuel airworthiness limitations. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective October 4, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 4, 
2018.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Airbus SAS Model 
A318, A319, and A320 series airplanes; and Model A321-111, -112, -131, 
-211, -212, -213, -231, -232, -251N, -253N, and -271N airplanes. The 
NPRM published in the Federal Register on April 27, 2018 (83 FR 18485). 
The NPRM was prompted by a revision of an airworthiness limitations 
document that specifies more restrictive maintenance requirements and 
airworthiness limitations. The NPRM proposed to require revising the 
maintenance or inspection program, as applicable, to incorporate 
revised fuel airworthiness limitations.
    We are issuing this AD to address the potential of ignition sources 
inside fuel tanks, which, in combination with flammable fuel vapors, 
could result in a fuel tank explosion and consequent loss of the 
airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0169, dated September 7, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A318, A319, and 
A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -
213, -231, -232, -251N, -253N, and -271N airplanes. The MCAI states:

    The Fuel Airworthiness Limitations (FAL) for Airbus A320 family 
aeroplanes, which are approved by EASA, are currently defined and 
published in the Airbus A318/A319/A320/A321 Airworthiness 
Limitations Section (ALS) Part 5 document. These instructions have 
been identified as mandatory for continued airworthiness. Failure to 
accomplish these instructions could result in a fuel tank explosion 
and consequent loss of the aeroplane.

[[Page 44210]]

    * * * the Federal Aviation Administration (FAA) published 
Special Federal Aviation Regulation (SFAR) 88, and the Joint 
Aviation Authorities (JAA) published interim Policy INT/POL/25/12. 
In response to these regulations, Airbus conducted a design review 
to develop FAL for Airbus A320 family aeroplanes.
    The FAL were specified in Airbus A318/A319/A320/A321 FAL 
document ref. 95A.1931/05 at issue 04 for A318/A319/A320/A321 
aeroplanes. This document was approved by EASA and is now referenced 
in Airbus A318/A319/A320/A321 ALS Part 5 to comply with EASA policy 
statement (EASA D2005/CPRO).
    Previously, EASA issued AD 2014-0260 [which corresponds to FAA 
AD 2016-20-12, Amendment 39-18678 (81 FR 72507, October 20, 2016) 
(``AD 2016-20-12'')] to require accomplishment of all FAL-related 
actions as described in ALS Part 5 at Revision 01. ALS Part 5 
Revision 02 and 03 were not mandated because no significant changes 
were introduced with these Revisions. The new ALS Part 5 Revision 04 
(hereafter referred to as `the ALS' in this [EASA] AD) includes new 
and/or more restrictive requirements and extends the applicability 
to model A320-251N, A320-271N, A321-251N, A321-253N and A321-271N 
aeroplanes.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0260, which is superseded, and requires 
implementation of the actions specified in the ALS.

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0300.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule as proposed with 
the changes described previously and minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued Airbus A318/A319/A320/A321 Airworthiness 
Limitations Section (ALS) Part 5 Fuel Airworthiness Limitations (FAL), 
Revision 04, dated April 6, 2017. This service information describes 
fuel system airworthiness limitations. 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.

Costs of Compliance

    We estimate that this AD affects 1,250 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:
    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, we estimate the total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).

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

    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.
