SUPPLEMENTARY INFORMATION: Discussion amozie on DSK3GDR082PROD with RULES We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A319 and A320 series airplanes; and Model A321– 111, –112, –131, –211, –212, –213, –231, and –232 airplanes. The NPRM published in the Federal Register on February 12, 2018 (83 FR 5960) (‘‘the NPRM’’). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017– 0161R1, dated September 19, 2017; corrected September 20, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A319 and A320 series airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. The MCAI states: Several occurrences have been reported of battery rod failures on certain Airbus aeroplanes. Subsequent examination of broken rod parts determined that these failures were due to quality defects of the material used during parts manufacturing. Each battery is secured on an aeroplane by two rods. Failure of one rod, in case of severe turbulence during flight or hard landing, could lead to battery displacement, or roll on the remaining rod side, up to a point where the remaining rod could be disengaged. The battery could ultimately detach from its housing and damage relays, connectors, VerDate Sep<11>2014 16:30 Aug 07, 2018 Jkt 244001 contactor boxes, air ducts and surrounding structure. This condition, if not detected and corrected, could lead to the loss of the normal electrical generation not followed by an automatic recovery of essential network. To address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A92N001–16 (later revised) and EASA issued AD 2016–0204 [which corresponds to FAA AD 2016–25–24 (81 FR 90958, December 16, 2016) (‘‘AD 2016–25–24’’)] requiring repetitive general visual inspections (GVI) of the four battery rods (two per battery), and, in case of findings, replacement of battery rods. Since that [EASA] AD was issued, the manufacturer of the broken battery retaining rods has been identified, which allows proper identification of the affected parts and their withdrawal from service. Consequently, Airbus issued [service bulletin] SB A320–92– 1116 and SB A320–92–1118 to provide the necessary instructions to the affected operators. No rods delivered as spare parts are affected by the manufacturing issue. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2016–0204, which is superseded, and requires replacement of battery retaining rods depending on manufacturer identification. This [EASA] AD also provides a terminating action for the repetitive inspections. 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– 0077. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Revise the Compliance Time Air Line Pilots Association, International (ALPA) requested that we revise the compliance time. ALPA stated that the proposed AD specifies a compliance time of within 24 months after the AD effective date. ALPA commented that because the proposed AD is related to quality, it believes this compliance time is insufficient. ALPA also commented that since the issuance of the manufacturer’s service information, operators have had over 12 months to comply with the required corrective actions. ALPA stated that, additionally, the time estimated to complete the inspections and replacement of the affected parts is minimal. ALPA recommended that we consider a compliance time of within 12 months after the AD effective date. We disagree with the commenter. While some U.S. operators have had time to plan and schedule the work contained in the Airbus service PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 information, there is no obligation for any U.S. operator to perform those actions without a regulatory requirement. Therefore, we agree with EASA’s decision to allow a 24-month compliance time to plan, schedule, and accomplish the actions necessary to remove the unsafe condition. If additional data are presented that would justify a shorter compliance time, we may consider further rulemaking on this issue. We have not changed this AD in this regard. Request To Revise the Definition of Serviceable Rod Delta Airlines (DAL) requested that we revise the definition of a serviceable rod in paragraph (g) of the proposed AD. DAL stated to add an additional paragraph that specifies: A battery retaining rod with an ISB [inspection service bulletin] label installed in accordance with the accomplishment instructions of Airbus Service Bulletin A320– 92–1116, Revision 00, dated January 31, 2017 (for Airbus Model A319 and A320 series airplanes; and A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes); or Airbus Service Bulletin A320–92–1118, Revision 00, dated January 31, 2017 (for Airbus Model A320–251N and –271N airplanes). We partially agree with revising the definition of a serviceable rod in paragraph (g) of this AD. We have determined that the installation of the ISB label does not affect the unsafe condition and have removed the requirement from this AD. We have coordinated this changed with EASA. Furthermore, we have revised paragraph (g) of this AD to clarify that the battery retaining rod used for replacement must be positively identified as a serviceable battery retaining rod. Request for Clarification Regarding Manufacturer Serial Numbers United Airlines (UAL) requested clarification regarding manufacturer serial numbers in the proposed AD. UAL stated that the manufacturer serial numbers are not applicable to the proposed AD as identified in Airbus Service Bulletin A320–92–1116, Revision 00, dated January 31, 2017, and Airbus Service Bulletin A320–92– 1118, Revision 00, dated January 31, 2017. UAL stated that, although the machining that caused the failure mode is identified in the service information, the same battery retaining rod part number used in pre- and post-service information remains unchanged. UAL commented that it is unclear whether a serial number, batch number, or date exists for those battery retaining rods. UAL also asked how were the battery E:\FR\FM\08AUR1.SGM 08AUR1 Federal Register / Vol. 83, No. 153 / Wednesday, August 8, 2018 / Rules and Regulations retaining rod spares deemed to be serviceable in paragraph (g)(1) of the proposed AD? We agree to provide clarification for the commenter. According to EASA AD 2017–0161R1, dated September 19, 2017; corrected September 20, 2017; no spares with manufacturing defects were delivered by Airbus. Only a certain batch of defective parts were installed in production on certain manufacturer serial numbers as specified in Airbus Service Bulletin A320–92–1116, Revision 00, dated January 31, 2017; and Airbus Service Bulletin A320–92– 1118, Revision 00, dated January 31, 2017. If an operator does not have an airplane affected as specified in the service information, then there is no concern relative to defective spare parts. We have not changed this AD in this regard. amozie on DSK3GDR082PROD with RULES Request To Clarify the Identification of Affected Parts DAL requested that we clarify the identification of the affected parts in paragraph (h) of the proposed AD. DAL stated that the detailed inspection to identify the battery retaining rod manufacturer should be of the battery support assemblies and not the battery retaining rods. We agree with the commenter’s request. We have revised paragraph (h) of this AD to require a detailed inspection of the battery support assemblies to identify the manufacturer of the battery retaining rods. Request To Include an Additional Method of Compliance to the AD Requirements DAL requested that we add an additional method of compliance for paragraphs (h), (i), and (j) of the proposed AD. DAL stated that the language, ‘‘or using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or EASA; or Airbus’s EASA Design Organization Approval (DOA),’’ should be included as an option to using the service information. DAL also stated that this language should be considered standard wording for future ADs as applicable. We disagree with the commenter’s request. We have already provided a method of compliance (MOC) for paragraphs (h), (i), and (j) of this AD in accordance with the applicable service information. Any deviations from the required MOC would need an evaluation in form of an AMOC. DAL’s proposed option is generally utilized in cases where no MOC has been established or we have known information that the MOC may not be VerDate Sep<11>2014 16:30 Aug 07, 2018 Jkt 244001 applicable for all airplanes in the U.S fleet. We have not changed the AD in this regard. Request To Not Require Certain Service Information Labels on the Battery Rod DAL and American Airlines (AA) requested that we not mandate that a service information label be attached to each battery retaining rod as required by the Airbus service information specified in paragraphs (j) and (l) of the proposed AD. AA also requested that we not mandate attachments of a service information label as part of the replacement required by paragraph (i) of the proposed AD. DAL stated that it has 7 affected airplanes that would have a different final configuration than the current and future fleet of 348 airplanes in its A320FAM fleet. AA stated that all battery retaining rods provided by Airbus post August 2016 are marked and stamped with manufactures part number (MPN) D8241023700000. AA commented that this marking of the new battery retaining rods can be used in lieu of the information service bulletin (ISB) label. AA also commented that it plans to replace all existing battery retaining rods with the new battery retaining rods that are marked with MPN D8241023700000. In addition, AA stated that installing the ISB label on the battery retaining rods on 128 of its A319/A320 airplanes does not add a safety value, but will put a burden on AA to maintain two different configurations of battery retaining rod installation between 128 airplanes that are effected by the service information in the proposed AD and 265 airplanes that are not affected by the service information in the proposed AD. We agree with the commenters’ request. We agree that the ISB label is not necessary to mitigate the risk addressed in this AD. Therefore, we have determined that the installation of ISB label should be optional and not a required for compliance (RC) step. However, 14 CFR 39.9, specifies that operators have a continuing obligation to maintain compliance with an AD, and the installation of the ISB label or an equivalent method to identify a serviceable battery retaining rod provides the operators with a simplified way to demonstrate compliance with the AD requirements. We have removed paragraph (j) of the proposed AD and revised paragraph (l) of this AD to revise the terminating action requirements. We have also added paragraph (j) of this AD to provide an exception to paragraph (i) of this AD, which specifies that installing the ISB label is not a requirement in this AD. PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 38961 Request To Revise the Terminating Action Paragraph DAL requested that paragraph (l) of the proposed AD, ‘‘Terminating Action,’’ be revised to read, ‘‘Replacement of all battery retaining rods,’’ and not, ‘‘Replacement of all battery retaining rods marked ‘SA. . . .’ ’’ DAL stated that the battery retaining rods are not marked with ‘‘SA,’’ only the battery support assemblies. We agree with the commenter’s request and have revised the AD accordingly. Request To Use Alternate Part Numbers Spirit Airlines requested that either the service information or the proposed AD be revised to provide the use of alternate materials to label part number (P/N) ASNE0248A1–4H9. Spirit Airlines stated that P/N ASNE0248A1–4H9 is no longer available, and that alternate P/N E0248A1–4H9P and P/N ASNE0248A1– 4H9T may be obtained from Airbus. Spirit Airlines believes that use of these alternate part numbers would provide an equivalent level of safety as referenced in Airbus Dossier Reference 80403684/003, dated January 8, 2018, and Airbus Retrofit Information Letter SA92M16012714 R00, dated February 1, 2017. DAL requested that a previously approved AMOC be used in the proposed AD. DAL stated that in paragraph (h) and (j) of the proposed AD, Airbus Service Bulletin A320–92– 1116, Revision 00, dated January 31, 2017, calls out a non-procurable part number for the identification label. Therefore, DAL proposed that recognition of AMOC AIR–676–18–152, issued against AD 2016–25–24, which allows an alternate label part number, be added to paragraph (m) of the proposed AD as an acceptable method of compliance to the proposed AD. We partially agree with the commenters request. As we stated previously, we have determined that installation of an ISB label is not an RC step. Therefore, a previously issued AMOC for allowing alternate label part numbers is unnecessary. However, we would like to remind operators that 14 CFR 39.9 specifies an operator’s continuing obligation to maintain compliance with an AD, and installation of an ISB label or an equivalent method provides operators with a method to demonstrate the affected battery retaining rods have been removed and replaced with serviceable retaining rods in compliance with the AD requirements. E:\FR\FM\08AUR1.SGM 08AUR1 38962 Federal Register / Vol. 83, No. 153 / Wednesday, August 8, 2018 / Rules and Regulations Differences Between This AD and the MCAI The MCAI includes a requirement to install an ISB label. This AD does not include that requirement. We have determined that the ISB label is not necessary to mitigate the risk addressed in this AD. However, 14 CFR 39.9, specifies that operators have a continuing obligation to maintain compliance with an AD, and the installation of the ISB label or an equivalent method to identify a serviceable battery retaining rod provides the operators with a simplified way to demonstrate compliance with the AD requirements. Conclusion We reviewed the relevant data, considered the comments 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 minor 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 A320–92–1116, Revision 00, dated January 31, 2017; and Service Bulletin A320–92–1118, Revision 00, dated January 31, 2017. This service information describes a detailed inspection of the battery support assemblies to identify the battery retaining rod manufacturer, replacement of the battery retaining rods with serviceable battery retaining rods if necessary, and adding the applicable service information label on each battery retaining rod if necessary. These documents are distinct since they apply to different airplane models. 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 330 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Inspection ................................ 1 work-hour × $85 per hour = $85 ......................................... We estimate the following costs to do any necessary replacement that would Cost per product Parts cost be required based on the results of the inspection.

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, VerDate Sep<11>2014 16:30 Aug 07, 2018 Jkt 244001 Cost per product Parts cost $0 $85 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. 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. Regulatory Findings List of Subjects in 14 CFR Part 39 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, Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION: Throughout this document ‘‘we,’’ ‘‘us,’’ and ‘‘our’’ means the EPA. PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 I. Background The SIP is a set of air pollution regulations, control strategies, and technical analyses developed by the state to ensure that the state meets the National Ambient Air Quality Standards (NAAQS). These ambient standards are established under section 109 of the Act and they currently address six criteria pollutants: Carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. The SIP is required by Section 110 of the Act and can be extensive, containing state regulations or other enforceable documents and supporting information such as emission inventories, monitoring networks, and modeling demonstrations. On March 24, 2017, the Governor of Arkansas submitted to the EPA revisions to the Arkansas SIP. The submittal includes revisions to the Regulations of the Arkansas Plan of Implementation for Air Pollution Control enacted at Arkansas Annotated Code (‘‘Ark. Code Ann.’’) Regulation 19 (‘‘Reg. 19’’), Chapters 1–5, 7, 9, 11, 13– 15, Appendix A, and Appendix B, and the Infrastructure and NAAQS SIPs. EPA has taken separate action on the following portions of this submittal: (1) On December 21, 2017, EPA approved the revisions to Reg. 19, Chapter 2, that address the definition of ‘‘Volatile Organic Compounds’’ (see 82 FR 60517); (2) On February 14, 2018, EPA approved the Infrastructure portion (see 83 FR 6470); (3) On June 29, 2018, EPA approved the revisions to Reg. 19, Chapter 4, that address Minor New Source Review (see 83 FR 30553); And, (4) on June 29, 2018, EPA proposed to approve the revisions that address interstate transport requirements for the 2012 PM2.5 NAAQS and the revisions to Reg. 19, Chapter 2 and Appendix B, that address the definition of 2012 PM2.5 in the definition of ‘‘NAAQS’’ and the table for ‘‘Particle Pollution, PM2.5’’ (see 83 FR 30622). Because these prior EPA actions did not address all the submitted revisions to Reg. 19, Chapter 2 and Appendix B, today’s action addresses the remaining submitted revisions to Reg. 19, Chapter 2 and Appendix B, and the submitted revisions to Reg. 19, Chapters 1, 3, 5, 13, 14, and 15. For a detailed list of each revision with our evaluation, please see our Technical Support Document (TSD) in the docket for this rulemaking. II.

Airworthiness Directives; Airbus 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 Model A319 and A320 series airplanes; and A321-111, -112, -131, 
-211, -212, -213, -231, and -232 airplanes. This AD was prompted by 
reports of battery retaining rod failures due to quality defects of the 
material used during parts manufacturing. This AD requires a detailed 
inspection of the battery support assemblies to identify the battery 
retaining rod manufacturer, replacement of the battery retaining rods 
with serviceable battery retaining rods if necessary, and the addition 
of the applicable service information label on each battery retaining 
rod if necessary. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective September 12, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 12, 
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 Model A319 
and A320 series airplanes; and Model A321-111, -112, -131, -211, -212, 
-213, -231, and -232 airplanes. The NPRM published in the Federal 
Register on February 12, 2018 (83 FR 5960) (``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0161R1, dated September 19, 2017; corrected September 20, 2017 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Airbus Model A319 and A320 series airplanes; and Model A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The MCAI 
states:

    Several occurrences have been reported of battery rod failures 
on certain Airbus aeroplanes. Subsequent examination of broken rod 
parts determined that these failures were due to quality defects of 
the material used during parts manufacturing. Each battery is 
secured on an aeroplane by two rods. Failure of one rod, in case of 
severe turbulence during flight or hard landing, could lead to 
battery displacement, or roll on the remaining rod side, up to a 
point where the remaining rod could be disengaged. The battery could 
ultimately detach from its housing and damage relays, connectors, 
contactor boxes, air ducts and surrounding structure.
    This condition, if not detected and corrected, could lead to the 
loss of the normal electrical generation not followed by an 
automatic recovery of essential network.
    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A92N001-16 (later revised) and EASA 
issued AD 2016-0204 [which corresponds to FAA AD 2016-25-24 (81 FR 
90958, December 16, 2016) (``AD 2016-25-24'')] requiring repetitive 
general visual inspections (GVI) of the four battery rods (two per 
battery), and, in case of findings, replacement of battery rods.
    Since that [EASA] AD was issued, the manufacturer of the broken 
battery retaining rods has been identified, which allows proper 
identification of the affected parts and their withdrawal from 
service. Consequently, Airbus issued [service bulletin] SB A320-92-
1116 and SB A320-92-1118 to provide the necessary instructions to 
the affected operators. No rods delivered as spare parts are 
affected by the manufacturing issue.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0204, which is superseded, and requires 
replacement of battery retaining rods depending on manufacturer 
identification. This [EASA] AD also provides a terminating action 
for the repetitive inspections.

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-
0077.

Comments

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

Request To Revise the Compliance Time

    Air Line Pilots Association, International (ALPA) requested that we 
revise the compliance time. ALPA stated that the proposed AD specifies 
a compliance time of within 24 months after the AD effective date. ALPA 
commented that because the proposed AD is related to quality, it 
believes this compliance time is insufficient. ALPA also commented that 
since the issuance of the manufacturer's service information, operators 
have had over 12 months to comply with the required corrective actions. 
ALPA stated that, additionally, the time estimated to complete the 
inspections and replacement of the affected parts is minimal. ALPA 
recommended that we consider a compliance time of within 12 months 
after the AD effective date.
    We disagree with the commenter. While some U.S. operators have had 
time to plan and schedule the work contained in the Airbus service 
information, there is no obligation for any U.S. operator to perform 
those actions without a regulatory requirement. Therefore, we agree 
with EASA's decision to allow a 24-month compliance time to plan, 
schedule, and accomplish the actions necessary to remove the unsafe 
condition. If additional data are presented that would justify a 
shorter compliance time, we may consider further rulemaking on this 
issue. We have not changed this AD in this regard.

Request To Revise the Definition of Serviceable Rod

    Delta Airlines (DAL) requested that we revise the definition of a 
serviceable rod in paragraph (g) of the proposed AD. DAL stated to add 
an additional paragraph that specifies:

    A battery retaining rod with an ISB [inspection service 
bulletin] label installed in accordance with the accomplishment 
instructions of Airbus Service Bulletin A320-92-1116, Revision 00, 
dated January 31, 2017 (for Airbus Model A319 and A320 series 
airplanes; and A321-111, -112, -131, -211, -212, -213, -231, and -
232 airplanes); or Airbus Service Bulletin A320-92-1118, Revision 
00, dated January 31, 2017 (for Airbus Model A320-251N and -271N 
airplanes).

    We partially agree with revising the definition of a serviceable 
rod in paragraph (g) of this AD. We have determined that the 
installation of the ISB label does not affect the unsafe condition and 
have removed the requirement from this AD. We have coordinated this 
changed with EASA. Furthermore, we have revised paragraph (g) of this 
AD to clarify that the battery retaining rod used for replacement must 
be positively identified as a serviceable battery retaining rod.

Request for Clarification Regarding Manufacturer Serial Numbers

    United Airlines (UAL) requested clarification regarding 
manufacturer serial numbers in the proposed AD. UAL stated that the 
manufacturer serial numbers are not applicable to the proposed AD as 
identified in Airbus Service Bulletin A320-92-1116, Revision 00, dated 
January 31, 2017, and Airbus Service Bulletin A320-92-1118, Revision 
00, dated January 31, 2017. UAL stated that, although the machining 
that caused the failure mode is identified in the service information, 
the same battery retaining rod part number used in pre- and post-
service information remains unchanged. UAL commented that it is unclear 
whether a serial number, batch number, or date exists for those battery 
retaining rods. UAL also asked how were the battery

[[Page 38961]]

retaining rod spares deemed to be serviceable in paragraph (g)(1) of 
the proposed AD?
    We agree to provide clarification for the commenter. According to 
EASA AD 2017-0161R1, dated September 19, 2017; corrected September 20, 
2017; no spares with manufacturing defects were delivered by Airbus. 
Only a certain batch of defective parts were installed in production on 
certain manufacturer serial numbers as specified in Airbus Service 
Bulletin A320-92-1116, Revision 00, dated January 31, 2017; and Airbus 
Service Bulletin A320-92-1118, Revision 00, dated January 31, 2017. If 
an operator does not have an airplane affected as specified in the 
service information, then there is no concern relative to defective 
spare parts. We have not changed this AD in this regard.

Request To Clarify the Identification of Affected Parts

    DAL requested that we clarify the identification of the affected 
parts in paragraph (h) of the proposed AD. DAL stated that the detailed 
inspection to identify the battery retaining rod manufacturer should be 
of the battery support assemblies and not the battery retaining rods.
    We agree with the commenter's request. We have revised paragraph 
(h) of this AD to require a detailed inspection of the battery support 
assemblies to identify the manufacturer of the battery retaining rods.

Request To Include an Additional Method of Compliance to the AD 
Requirements

    DAL requested that we add an additional method of compliance for 
paragraphs (h), (i), and (j) of the proposed AD. DAL stated that the 
language, ``or using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or EASA; or Airbus's EASA 
Design Organization Approval (DOA),'' should be included as an option 
to using the service information. DAL also stated that this language 
should be considered standard wording for future ADs as applicable.
    We disagree with the commenter's request. We have already provided 
a method of compliance (MOC) for paragraphs (h), (i), and (j) of this 
AD in accordance with the applicable service information. Any 
deviations from the required MOC would need an evaluation in form of an 
AMOC. DAL's proposed option is generally utilized in cases where no MOC 
has been established or we have known information that the MOC may not 
be applicable for all airplanes in the U.S fleet. We have not changed 
the AD in this regard.

Request To Not Require Certain Service Information Labels on the 
Battery Rod

    DAL and American Airlines (AA) requested that we not mandate that a 
service information label be attached to each battery retaining rod as 
required by the Airbus service information specified in paragraphs (j) 
and (l) of the proposed AD. AA also requested that we not mandate 
attachments of a service information label as part of the replacement 
required by paragraph (i) of the proposed AD. DAL stated that it has 7 
affected airplanes that would have a different final configuration than 
the current and future fleet of 348 airplanes in its A320FAM fleet.
    AA stated that all battery retaining rods provided by Airbus post 
August 2016 are marked and stamped with manufactures part number (MPN) 
D8241023700000. AA commented that this marking of the new battery 
retaining rods can be used in lieu of the information service bulletin 
(ISB) label. AA also commented that it plans to replace all existing 
battery retaining rods with the new battery retaining rods that are 
marked with MPN D8241023700000.
    In addition, AA stated that installing the ISB label on the battery 
retaining rods on 128 of its A319/A320 airplanes does not add a safety 
value, but will put a burden on AA to maintain two different 
configurations of battery retaining rod installation between 128 
airplanes that are effected by the service information in the proposed 
AD and 265 airplanes that are not affected by the service information 
in the proposed AD.
    We agree with the commenters' request. We agree that the ISB label 
is not necessary to mitigate the risk addressed in this AD. Therefore, 
we have determined that the installation of ISB label should be 
optional and not a required for compliance (RC) step.
    However, 14 CFR 39.9, specifies that operators have a continuing 
obligation to maintain compliance with an AD, and the installation of 
the ISB label or an equivalent method to identify a serviceable battery 
retaining rod provides the operators with a simplified way to 
demonstrate compliance with the AD requirements. We have removed 
paragraph (j) of the proposed AD and revised paragraph (l) of this AD 
to revise the terminating action requirements. We have also added 
paragraph (j) of this AD to provide an exception to paragraph (i) of 
this AD, which specifies that installing the ISB label is not a 
requirement in this AD.

Request To Revise the Terminating Action Paragraph

    DAL requested that paragraph (l) of the proposed AD, ``Terminating 
Action,'' be revised to read, ``Replacement of all battery retaining 
rods,'' and not, ``Replacement of all battery retaining rods marked 
`SA. . . .' '' DAL stated that the battery retaining rods are not 
marked with ``SA,'' only the battery support assemblies.
    We agree with the commenter's request and have revised the AD 
accordingly.

Request To Use Alternate Part Numbers

    Spirit Airlines requested that either the service information or 
the proposed AD be revised to provide the use of alternate materials to 
label part number (P/N) ASNE0248A1-4H9. Spirit Airlines stated that P/N 
ASNE0248A1-4H9 is no longer available, and that alternate P/N E0248A1-
4H9P and P/N ASNE0248A1-4H9T may be obtained from Airbus. Spirit 
Airlines believes that use of these alternate part numbers would 
provide an equivalent level of safety as referenced in Airbus Dossier 
Reference 80403684/003, dated January 8, 2018, and Airbus Retrofit 
Information Letter SA92M16012714 R00, dated February 1, 2017.
    DAL requested that a previously approved AMOC be used in the 
proposed AD. DAL stated that in paragraph (h) and (j) of the proposed 
AD, Airbus Service Bulletin A320-92-1116, Revision 00, dated January 
31, 2017, calls out a non-procurable part number for the identification 
label. Therefore, DAL proposed that recognition of AMOC AIR-676-18-152, 
issued against AD 2016-25-24, which allows an alternate label part 
number, be added to paragraph (m) of the proposed AD as an acceptable 
method of compliance to the proposed AD.
    We partially agree with the commenters request. As we stated 
previously, we have determined that installation of an ISB label is not 
an RC step. Therefore, a previously issued AMOC for allowing alternate 
label part numbers is unnecessary. However, we would like to remind 
operators that 14 CFR 39.9 specifies an operator's continuing 
obligation to maintain compliance with an AD, and installation of an 
ISB label or an equivalent method provides operators with a method to 
demonstrate the affected battery retaining rods have been removed and 
replaced with serviceable retaining rods in compliance with the AD 
requirements.

[[Page 38962]]

Differences Between This AD and the MCAI

    The MCAI includes a requirement to install an ISB label. This AD 
does not include that requirement. We have determined that the ISB 
label is not necessary to mitigate the risk addressed in this AD. 
However, 14 CFR 39.9, specifies that operators have a continuing 
obligation to maintain compliance with an AD, and the installation of 
the ISB label or an equivalent method to identify a serviceable battery 
retaining rod provides the operators with a simplified way to 
demonstrate compliance with the AD requirements.

Conclusion

    We reviewed the relevant data, considered the comments 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 minor 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 A320-92-1116, Revision 00, dated 
January 31, 2017; and Service Bulletin A320-92-1118, Revision 00, dated 
January 31, 2017. This service information describes a detailed 
inspection of the battery support assemblies to identify the battery 
retaining rod manufacturer, replacement of the battery retaining rods 
with serviceable battery retaining rods if necessary, and adding the 
applicable service information label on each battery retaining rod if 
necessary. These documents are distinct since they apply to different 
airplane models. 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 330 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    We estimate the following costs to do any necessary replacement 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need this 
replacement:

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.

    This AD was prompted by reports of battery retaining rod 
failures due to quality defects of the material used during parts 
manufacturing. We are issuing this AD to detect and correct broken 
battery retaining rods, which, in the event of a hard landing or 
severe turbulence, could cause the battery to detach from its 
housing, resulting in damage to other electrical equipment and 
surrounding structure. This condition could lead to loss of normal 
electrical power generation and subsequent inability to restore 
electrical power to essential airplane systems.

(f) Compliance

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

(g) Definition of a Serviceable Rod

    For the purpose of this AD, a serviceable battery retaining rod 
is defined in paragraphs (g)(1) or (g)(2) of this AD.
    (1) A battery retaining rod provided as a spare part by Airbus.
    (2) A battery retaining rod previously fitted on a battery 
support assembly installed on an airplane manufacturer serial number 
that is not specified in Airbus Service Bulletin A320-92-1116, 
Revision 00, dated January 31, 2017 (for Airbus Model A319 and A320 
series airplanes; and Model A321-111, -112, -131, -211, -212, -213, 
-231, and -232 airplanes); or Airbus Service Bulletin A320-92-1118, 
Revision 00, dated January 31, 2017 (for Airbus Model A320-251N and 
-271N airplanes), provided the battery retaining rod used for 
replacement can be positively identified as a serviceable battery 
retaining rod.

(h) Identification of Affected Parts

a detailed inspection of the battery support assemblies to identify 
the battery retaining rod manufacturer, in accordance with the 
Accomplishment Instructions of the Airbus Service Bulletin A320-92-
1116, Revision 00, dated January 31, 2017 (for Airbus Model A319 and 
A320 series airplanes, and Model A321-111, -112, -131, -211, -212, -
213, -231, and -232 airplanes); or Airbus Service Bulletin A320-92-
1118, Revision 00, dated January 31, 2017 (for Airbus Model A320-
251N and -271N airplanes).

(i) Replacement of Affected Parts if Marking Is Found on Battery 
Support Assembly

    If, during the inspection specified in paragraph (h) of this AD, 
the quality stamp on any battery support assemblies are found marked 
with an ``SA'' manufacturer identification, before further flight, 
replace the battery retaining rods with serviceable battery 
retaining rods, in accordance with the Accomplishment Instructions 
of the Airbus Service Bulletin A320-92-1116, Revision 00, dated 
January 31, 2017 (for Airbus Model A319 and A320 series airplanes; 
and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 
airplanes); or Airbus Service Bulletin A320-92-1118, Revision 00, 
dated January 31, 2017 (for Airbus Model A320-251N and -271N 
airplanes); except as provided by paragraph (j) of this AD.

(j) Exception to the Service Information

    Although Airbus Service Bulletin A320-92-1116, Revision 00, 
dated January 31, 2017; and Airbus Service Bulletin A320-92-1118, 
Revision 00, dated January 31, 2017; specify to install inspection 
service bulletin (ISB) labels, this AD does not include that 
requirement.

(k) Parts Installation Prohibition

    As of the effective date of this AD, no person may install, on 
any airplane, a non-serviceable battery retaining rod.

(l) Terminating Action

    Replacement of all battery retaining rods with a serviceable 
battery retaining rod as required by paragraph (i) of this AD 
constitutes terminating action for all requirements of AD 2016-25-24 
for that airplane.

(m) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Section, send it to the attention of 
the person identified in paragraph (n)(2) of this AD. Information 
may be emailed to: [email protected]. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office.
    (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'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.
