We are superseding Airworthiness Directive (AD) 2016-02-01, which applied to certain Airbus Model A320-211, -212, and -231 airplanes. AD 2016-02-01 required repetitive inspections to detect cracks of the pressurized floor fittings at a certain frame, and renewal of the zone protective finish or replacement of fittings with new fittings if necessary. AD 2016-02-01 also provided an optional modification that was terminating action for the repetitive inspections. This new AD retains the requirements of AD 2016-02-01, and requires accomplishment of the modification that was optional in AD 2016-02-01. This AD was prompted by the results of an additional fatigue analysis of cracking of the pressurized floor fittings and a determination that the optional modification should become a required action. We are issuing this AD to address the unsafe condition on these products.

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2016-02-01, 
which applied to certain Airbus Model A320-211, -212, and -231 
airplanes. AD 2016-02-01 required repetitive inspections to detect 
cracks of the pressurized floor fittings at a certain frame, and 
renewal of the zone protective finish or replacement of fittings with 
new fittings if necessary. AD 2016-02-01 also provided an optional 
modification that was terminating action for the repetitive 
inspections. This new AD retains the requirements of AD 2016-02-01, and 
requires accomplishment of the modification that was optional in AD 
2016-02-01. This AD was prompted by the results of an additional 
fatigue analysis of cracking of the pressurized floor fittings and a 
determination that the optional modification should become a required 
action. We are issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective March 2, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of March 
3, 2016 (81 FR 4878, January 28, 2016).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2016-02-01, Amendment 39-18380 (81 FR 4878, 
January 28, 2016) (``AD 2016-02-01''). AD 2016-02-01 applied to certain 
Airbus Model A320-211, -212, and -231 airplanes. The NPRM published in 
the Federal Register on August 15, 2017 (82 FR 38618).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0181, dated September 13, 2016 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A320-211, -212, 
and -231 airplanes. The MCAI states:

    During centre fuselage certification full scale fatigue testing, 
damage was found on the pressurized floor fittings at Frame (FR) 36, 
below the lower surface panel.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    To prevent such damage, Airbus developed modification 21282, 
which was introduced in production from MSN [manufacturer serial 
number] 0105, to reinforce the pressurized floor fitting lower 
surface by changing material. For affected in-service aeroplanes, 
Airbus issued Service Bulletin (SB) A320-57-1028, introducing 
repetitive inspections, and SB A320-57-1029, which provides 
modification instructions.
    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France issued AD 95-099-067 to require these repetitive inspections 
and, depending on findings, corrective action(s), while the 
modification was specified in that [French] AD as optional 
terminating action for these inspections.
    Following new analysis in the frame of Extended Service Goal 
exercise, the inspection thresholds and intervals were revised to 
meet the original Design Service Goal. Consequently, EASA issued AD 
2013-0226 [which corresponds to FAA AD 2016-02-01 (81 FR 4878, 
January 28, 2016)] to retain the requirements of DGAC France AD 95-
099-067, which was superseded, but required those actions within 
reduced compliance times.
    Since that [EASA] AD was issued, in the frame of Widespread 
Fatigue Damages analysis, the situation has been reassessed and it 
has been decided to reclassify the modification, still stated as 
`optional' terminating action in EASA AD 2013-0226, to the status 
`mandatory'.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2013-0226, which is superseded, but requires 
embodiment of the modification as specified in Airbus SB A320-57-
1029.

    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-2017-
0716.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to that comment.

Request To Revise the Applicability

    Allegiant Air noted that the applicability specified in paragraph 
(c) of the proposed AD included Airbus Model A320-214 airplanes. The 
commenter asked if Model A320-214 airplanes were included in the 
applicability in error. The commenter observed that neither the 
applicability of AD 2016-02-01 or EASA AD 2016-0181, nor the 
effectivity of Airbus Service Bulletin A320-57-1028, Revision 02, dated 
June 3, 2013, included Model A320-214 airplanes.
    We infer that the commenter is requesting that Model A320-214 
airplanes be removed from the applicability of the proposed AD. We 
agree, for the reasons provided by the commenter. This final rule is 
not applicable to Model A320-214 airplanes; therefore, we have revised 
the

[[Page 3565]]

applicability specified in paragraph (c) of this AD by removing Model 
A320-214 airplanes.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting 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 AD.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-57-1028, Revision 02, dated 
June 3, 2013. The service information describes procedures for an 
inspection to detect cracks of the pressurized floor fittings at FR 36, 
renewal of the zone protective finish, and replacement of fittings with 
new fittings.
    Airbus has also issued Service Bulletin A320-57-1029, Revision 02, 
dated June 16, 1999. The service information describes procedures for 
modification of the pressurized floor fittings at FR 36.
    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 13 airplanes of U.S. registry. We 
estimate the following costs to comply with 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.
