SUPPLEMENTARY INFORMATION: Discussion The FAA 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, A320, and A321 series airplanes. The NPRM published in the Federal Register on March 5, 2019 (84 FR 7835). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive fuel airworthiness limitations. The FAA is 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 2018–0231, dated October 25, 2018 (‘‘AD 2018– 0231’’) (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus SAS Model A318, A319, A320, and A321 series airplanes. The MCAI states: The Airworthiness Limitations for the Airbus A320 family aeroplanes, which are approved by EASA, are currently defined and published in the A318/A319/A320/A321 ALS document(s). The Fuel Airworthiness Limitations (FAL) are published in ALS Part 5. Failure to accomplish these instructions could result in an unsafe condition. Previously, EASA issued AD 2017–0169 [which corresponds to FAA AD 2018–17–21, Amendment 39–19375 (83 FR 44209, August 30, 2018) (‘‘AD 2018–17–21’’)] to require accomplishment of all maintenance tasks and replacement of life limited parts as described in ALS Part 5 at Revision 04. Since that [EASA] AD was issued, Airbus published the ALS, including new and/or more restrictive requirements, and new A320 family models were certified and added to the Applicability. For the reason described above, this [EASA] AD retains the requirements of EASA PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 AD 2017–0169, which is superseded, expands the Applicability and requires accomplishment of the actions specified in the ALS. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 0116. Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for the NPRM Matthew Flanders, Cristian Silva, and Ben Troike, stated their support for the NPRM. United Airlines (UAL) stated that it fully agrees with the proposed requirements. Request To Supersede Related AD UAL requested that we supersede AD 2018–17–21. UAL stated that EASA AD 2018–0231 provides equivalent requirements as the proposed AD. In addition, UAL commented that the requirements in the proposed AD terminates all the requirements in AD 2018–17–21; therefore, the proposed AD should supersede AD 2018–17–21. The FAA disagrees with issuing this final rule as a supersedure AD. As stated in the NPRM, the FAA determined that a stand-alone AD is more appropriate to address the actions in the MCAI because it is more streamlined for the FAA to release stand-alone ADs, compared to the supersedure ADs. The FAA considered the entire fleet size that would be affected by superseding AD 2018–17–21 and the consequent workload associated with revising maintenance record entries. In light of this, the FAA determined that a less burdensome approach is to issue a separate AD. Further, revising this AD as requested would necessitate (under the provisions of the Administrative Procedure Act) reissuing the notice, reopening the period for public comment, considering additional comments subsequently received, and eventually issuing a final rule. Therefore, in consideration of the unsafe condition, the FAA has determined that further delay of this AD is not appropriate. The FAA has not changed this AD in this regard. Changes Made to This Final Rule The FAA has determined that Airbus SAS Model A320–252N airplanes were inadvertently omitted from the Applicability of the proposed AD. E:\FR\FM\25JYR1.SGM 25JYR1 Federal Register / Vol. 84, No. 143 / Thursday, July 25, 2019 / Rules and Regulations Therefore, the FAA has updated paragraph (c)(3) of this AD to add those airplanes. Since there are currently no domestic operators of this product, additional notice and opportunity for public comment before issuing this AD are unnecessary. In the ‘‘Costs of Compliance’’ paragraph, we have updated the figure to 1,497 airplanes to reflect the current number of airplanes on the U.S. registry. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the change described previously and minor editorial changes. The FAA has 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. Related Service Information Under 1 CFR Part 51 Airbus SAS has issued A318/A319/ A320/A321 Airworthiness Limitations Section (ALS), Part 5, Fuel Airworthiness Limitations (FAL), Revision 05, dated June 13, 2018. This service information describes fuel airworthiness limitations items and critical design configuration control limitations (CDCCLs). 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. jspears on DSK30JT082PROD with RULES Costs of Compliance The FAA estimates that this AD affects 1,497 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD. The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the agency recognizes that this number may vary from operator to operator. In the past, the FAA has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). VerDate Sep<11>2014 16:09 Jul 24, 2019 Jkt 247001 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 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) 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.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA 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, A320, and A321 series airplanes. The NPRM published 
in the Federal Register on March 5, 2019 (84 FR 7835). The NPRM was 
prompted by a determination that new or more restrictive airworthiness 
limitations are necessary. The NPRM proposed to require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive fuel airworthiness limitations.
    The FAA is 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 
2018-0231, dated October 25, 2018 (``AD 2018-0231'') (referred to after 
this as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition for certain Airbus SAS Model 
A318, A319, A320, and A321 series airplanes. The MCAI states:

    The Airworthiness Limitations for the Airbus A320 family 
aeroplanes, which are approved by EASA, are currently defined and 
published in the A318/A319/A320/A321 ALS document(s). The Fuel 
Airworthiness Limitations (FAL) are published in ALS Part 5.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    Previously, EASA issued AD 2017-0169 [which corresponds to FAA 
AD 2018-17-21, Amendment 39-19375 (83 FR 44209, August 30, 2018) 
(``AD 2018-17-21'')] to require accomplishment of all maintenance 
tasks and replacement of life limited parts as described in ALS Part 
5 at Revision 04.
    Since that [EASA] AD was issued, Airbus published the ALS, 
including new and/or more restrictive requirements, and new A320 
family models were certified and added to the Applicability.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2017-0169, which is superseded, expands the 
Applicability and requires accomplishment of the actions specified 
in the ALS.

    You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0116.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment.

Support for the NPRM

    Matthew Flanders, Cristian Silva, and Ben Troike, stated their 
support for the NPRM. United Airlines (UAL) stated that it fully agrees 
with the proposed requirements.

Request To Supersede Related AD

    UAL requested that we supersede AD 2018-17-21. UAL stated that EASA 
AD 2018-0231 provides equivalent requirements as the proposed AD. In 
addition, UAL commented that the requirements in the proposed AD 
terminates all the requirements in AD 2018-17-21; therefore, the 
proposed AD should supersede AD 2018-17-21.
    The FAA disagrees with issuing this final rule as a supersedure AD. 
As stated in the NPRM, the FAA determined that a stand-alone AD is more 
appropriate to address the actions in the MCAI because it is more 
streamlined for the FAA to release stand-alone ADs, compared to the 
supersedure ADs. The FAA considered the entire fleet size that would be 
affected by superseding AD 2018-17-21 and the consequent workload 
associated with revising maintenance record entries. In light of this, 
the FAA determined that a less burdensome approach is to issue a 
separate AD. Further, revising this AD as requested would necessitate 
(under the provisions of the Administrative Procedure Act) reissuing 
the notice, reopening the period for public comment, considering 
additional comments subsequently received, and eventually issuing a 
final rule. Therefore, in consideration of the unsafe condition, the 
FAA has determined that further delay of this AD is not appropriate. 
The FAA has not changed this AD in this regard.

Changes Made to This Final Rule

    The FAA has determined that Airbus SAS Model A320-252N airplanes 
were inadvertently omitted from the Applicability of the proposed AD.

[[Page 35813]]

Therefore, the FAA has updated paragraph (c)(3) of this AD to add those 
airplanes. Since there are currently no domestic operators of this 
product, additional notice and opportunity for public comment before 
issuing this AD are unnecessary.
    In the ``Costs of Compliance'' paragraph, we have updated the 
figure to 1,497 airplanes to reflect the current number of airplanes on 
the U.S. registry.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule with the change described previously 
and minor editorial changes. The FAA has 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.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued A318/A319/A320/A321 Airworthiness Limitations 
Section (ALS), Part 5, Fuel Airworthiness Limitations (FAL), Revision 
05, dated June 13, 2018. This service information describes fuel 
airworthiness limitations items and critical design configuration 
control limitations (CDCCLs).
    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

    The FAA estimates that this AD affects 1,497 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD.
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. In the past, the FAA has estimated that this action takes 
1 work-hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), the FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the FAA estimates 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.
    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 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) 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.

Revision 05, dated June 13, 2018. The initial compliance time for 
doing the tasks is at the time specified in Airbus A318/A319/A320/
A321 Airworthiness Limitations Section (ALS), Part 5, Fuel 
Airworthiness Limitations (FAL), Revision 05, dated June 13, 2018, 
or within 90 days after the effective date of this AD, whichever 
occurs later.

(h) No Alternative Actions, Intervals, or Critical Design Configuration 
Control Limitations (CDCCLs)

    After the maintenance or inspection program has been revised as 
required by paragraph (g) of this AD, no alternative actions (e.g., 
inspections), intervals, or CDCCLs may be used unless the actions, 
intervals, and CDCCLs are approved as an alternative method of 
compliance (AMOC) in accordance with the procedures specified in 
paragraph (j)(1) of this AD.

(i) Terminating Action for AD 2018-17-21

    Accomplishing the actions required by this AD terminates all 
requirements of AD 2018-17-21.

AMOCs for the corresponding provisions of this AD.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or the European Aviation 
Safety Agency (EASA); or Airbus SAS's EASA Design Organization 
Approval (DOA). If approved by the DOA, the approval must include 
the DOA-authorized signature.
    (3) Required for Compliance (RC): If any service information 
contains procedures or tests that are identified as RC, those 
procedures and tests must be done to comply with this AD; any 
procedures or tests that are not identified as RC are recommended. 
Those procedures and tests that are not identified as RC may be 
deviated from using accepted methods in accordance with the 
operator's maintenance or inspection program without obtaining 
approval of an AMOC, provided the procedures and tests identified as 
RC can be done and the airplane can be put back in an airworthy 
condition. Any substitutions or changes to procedures or tests 
identified as RC require approval of an AMOC.
