This AD was June 16, 2015) (‘‘AD 2015–12–08’’). AD prompted by further investigation that 2015–12–08 applied to all Airbus SAS determined that affected oxygen pipes Model A318–111, A318–112, A318–121, may have been installed on more A318–122, A319–111, A319–112, A319– airplanes than initially identified. We 113, A319–114, A319–115, A319–131, are issuing this AD to address the unsafe A319–132, A319–133, A320–211, A320– condition on these products. 212, A320–214, A320–231, A320–232, A320–233, A321–111, A320–112, A320– DATES: This AD is effective April 16, 131, A320–211, A320–212, A320–213, 2019.

The Director of the Federal Register approved the incorporation by reference The NPRM published in the Federal of a certain publication listed in this AD Register on October 4, 2018 (83 FR 50047). The NPRM was prompted by as of April 16, 2019. further investigation that determined The Director of the Federal Register approved the incorporation by reference that affected oxygen pipes may have been installed on more airplanes than of a certain other publication listed in VerDate Sep<11>2014 16:10 Mar 11, 2019 Jkt 247001 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 8795 initially identified. The NPRM proposed to revise the applicability to include additional airplane models and additional pipes to be replaced if necessary. We are issuing this AD to address corrosion of the oxygen pipe assemblies, which could lead to blocked or reduced oxygen supply to a flight crew member in case of decompression or smoke/fire in the flight deck. In addition, the presence of particles in oxygen lines, under certain conditions, increases the risk of fire in the flight deck. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018– 0060R1, dated July 19, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A318 and A319 series airplanes; all Model A320– 211, A320–212, A320–214, A320–216, A320–231, A320–232, A320–233, A321– 111, A321–112, A321–131, A321–211, A321–212, A321–213, A321–231, and A321–232 airplanes; and certain Model A320–251N, A320–271N, and A321– 271N airplanes. The MCAI states: Some oxygen pipe assemblies were found corroded during manufacturing at supplier level. The affected pipe assembly was installed at the end of the right hand (RH) crew distribution line, just upstream of the First Officer and RH Observer oxygen mask boxes. The investigation showed that the affected pipes had been heat treated just 4 weeks before the summer factory closure and were only cleaned after re-opening of the factory. During this interruption, corrosion developed in these pipes. This condition, if not detected and corrected, could lead to blocked or reduced oxygen supply to a flight crew member in case of decompression or smoke/fire in the cockpit. In addition, the presence of particles in oxygen lines, under certain conditions, increases the risk of fire in the cockpit. The parts manufacturer identified the batch numbers of the potentially affected pipes that were manufactured in a specific period in 2011. Based on that information, Airbus identified the aeroplanes on which those pipes were installed on the production line and issued [service bulletin] SB A320– 35–1069, containing instructions to remove the affected pipes from service. Consequently, EASA issued AD 2013–0278 [which corresponds to FAA AD 2015–12–08] to require the identification and replacement of the affected oxygen pipes. That [EASA] AD also prohibited installation of any affected pipe on other aeroplanes. After EASA AD 2013–0278 was issued, further investigation determined that affected oxygen pipes may have been installed on more aeroplanes than initially identified. Consequently, Airbus revised SB A320–35– 1069 and EASA issued AD 2017–0150, E:\FR\FM\12MRR1.SGM 12MRR1 8796 Federal Register / Vol. 84, No. 48 / Tuesday, March 12, 2019 / Rules and Regulations retaining the requirements of EASA AD 2013–0278, which was superseded, and requiring the same actions on these additional aeroplanes. After EASA AD 2017–0150 was issued, it was determined that five A320 and A321 NEO aeroplanes had been delivered with a configuration which potentially allows the installation of an affected oxygen pipe. Consequently, EASA issued AD 2018– 0060, retaining the requirements of EASA AD 2017–0150, which was superseded, expanding the Applicability to include the five A320 and A321 NEO aeroplanes, and correcting the Table in Appendix 1 by removing MSN [manufacturer serial number] 5091 which belongs to Group 2. Since that AD was issued, several operator requests were received to clarify the required actions for Group 3 and Group 4 aeroplanes. It was determined that, as per Airbus configuration control, the EASA AD No.: 2018–0060R1 affected parts have been identified as being potentially installed in production only on Group 1 and Group 2 aeroplanes. However, it is possible that those parts migrated to other aeroplanes during maintenance; for that reason, Group 3 and 4 aeroplanes need to be considered. This [EASA] AD is revised accordingly. 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–2018– 0806. Comments We 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 Air Line Pilots Association, International (ALPA) stated its support for the NPRM. Request To Add Airplanes to Paragraph (j) of the Proposed AD American Airlines requested that additional airplanes be added to paragraph (j) of the proposed AD. American Airlines asserted that Airbus has identified additional airplanes, which are included in Revision 02, dated October 26, 2016; and Revision 03, dated December 8, 2017; of Airbus Service Bulletin A320–35–1069. We disagree with the request to add airplanes to paragraph (j) of this AD, which contains a new action for those airplanes not affected by AD 2015–12– 18. The airplanes identified by the commenter are already included in paragraph (h) of this AD, which contains a retained action from AD 2015–12–18. Adding those airplanes to paragraph (j) of this AD would result in redundant requirements for those airplanes. We have not changed this AD in this regard. VerDate Sep<11>2014 16:10 Mar 11, 2019 Jkt 247001 Request To Specify No Reporting American Airlines requested that we do not require the reporting specified in Airbus Service Bulletin A320–35–1069, Revision 03, dated December 8, 2017. American Airlines stated that this action is not related to the unsafe condition. We agree with the request. We have added paragraph (l) to this AD to specify no reporting is required. We have redesignated subsequent paragraphs of this AD accordingly. Request To Remove Location for Accomplishing a Certain Action American Airlines requested that we remove the location from the requirement to flush certain removed parts. American Airlines stated that Airbus Service Bulletin A320–35–1069, Revision 03, dated December 8, 2017, specifies doing that action in the shop. American Airlines stated that the location of performing that maintenance action is not relevant to correcting the unsafe condition. We agree with the request for the reason provided by the commenter. We have added paragraph (m)(1) to this AD to specify that the location to flush certain parts is not required by this AD. Request for Alternative Part Numbers American Airlines requested that we include alternative parts for washer part number (P/N) AN960C816. American Airlines stated that Airbus Service Bulletin A320–35–1069, Revision 03, dated December 8, 2017, specifies to install the new crew oxygen pipe with P/N AN960C816, but that part number is obsolete. American Airlines stated that part number can be replaced with alternate P/N NAS1149C0863R, as specified in Illustrated Parts Catalog (IPC) 35–12–01–03, Item 110. American Airlines requested that we allow the installation of alternate parts as specified in the IPC. We partially agree with the commenter. We disagree to allow installation of any alternative part specified in the IPC because the IPC is not FAA-approved data. However, we agree to allow the use of alternate P/N NAS1149C0863R. We have added paragraph (m)(2) to this AD to allow the use of that alternate part number. Clarification of Requirements for Model A320–216 Airplanes We stated the following in the NPRM: The Airbus SAS Model A320–216 was type certificated on December 19, 2016. Before that date, any EASA AD that affected Model A320–216 airplanes was included on the Required Airworthiness Action List (RAAL). Model A320–216 airplanes have subsequently been PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 placed on the U.S. Register, and will now be included in FAA AD actions. For Airbus SAS Model A320–216 airplanes, the requirements that correspond to AD 2015–12–08 were mandated by the MCAI via the RAAL. Although that RAAL requirement is still in effect, for continuity and clarity we have identified Airbus SAS Model A320–216 airplanes in paragraph (c) of this AD; the restated requirements of paragraphs (g), (h), and (i) of this AD would therefore apply to those airplanes. However, in paragraph (i) of the NPRM, we excluded Airbus SAS Model A320–216 airplanes. We also included those airplanes in the new requirements in paragraphs (j) and (k) of the NPRM. We should not have excluded Airbus SAS Model A320–216 airplanes in paragraph (i) of the NPRM since the restated requirements of that paragraph still apply to those airplanes via the RAAL. Likewise, those airplanes should not have been included in the new requirements of paragraphs (j) and (k) of the NPRM because the requirements were already addressed by the restated requirements of paragraphs (g), (h), and (i) of the NPRM (which correspond to the actions required by the MCAI, EASA AD 2013–0278, via the RAAL). Therefore, we have removed references to Airbus SAS Model A320–216 airplanes from paragraphs (j) and (k) of this AD, and removed the text excluding Airbus SAS Model A320–216 from paragraph (i) of this AD. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule 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 has issued Service Bulletin A320–35–1069, Revision 03, dated December 8, 2017. The service information describes an inspection to determine the batch number or installation date of the oxygen pipe assembly that is installed at the end of E:\FR\FM\12MRR1.SGM 12MRR1 8797 Federal Register / Vol. 84, No. 48 / Tuesday, March 12, 2019 / Rules and Regulations the right-hand crew distribution line, and replacement of the pipe. This AD also requires Airbus Service Bulletin A320–35–1069, dated April 26, 2013, which the Director of the Federal Register approved for incorporation by reference as of July 21, 2015 (80 FR 34262, June 16, 2015). 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 50 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Parts cost Cost per product Cost on U.S. operators 2 work-hours × $85 per hour = $170 .......................................................................................... $0 $170 $8,500 We estimate the following costs to do any necessary replacements that would be required based on the results of the required inspection. We have no way of determining the number of aircraft that might need these replacements: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 5 work-hours × $85 per hour = $425 ...................................................................................................................... $0 $425 According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all known costs in our cost estimate. 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 VerDate Sep<11>2014 16:10 Mar 11, 2019 Jkt 247001 delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division. PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Regulatory Findings Authority: 49 U.S.C. 106(g), 40113, 44701. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2015–12–08, Amendment 39–18182 (80 FR 34262, June 16, 2015), and adding the following new AD: ■ 2019–05–08 Airbus SAS: Amendment 39– 19590; Docket No. FAA–2018–0806; Product Identifier 2018–NM–056–AD. (a) Effective Date This AD is effective April 16, 2019. (b) Affected ADs This AD replaces AD 2015–12–08, Amendment 39–18182 (80 FR 34262, June 16, 2015) (‘‘AD 2015–12–08’’). (c) Applicability This AD applies to the Airbus SAS airplanes identified in paragraphs (c)(1) through (c)(5) of this AD, certificated in any category. (1) Model A318–111, –112, –121, and –122 airplanes, all manufacturer serial numbers. (2) Model A319–111, –112, –113, –114, –115, –131, –132, and –133 airplanes, all manufacturer serial numbers. (3) Model A320–211, –212, –214, –216, –231, –232, and –233 airplanes, all manufacturer serial numbers.

E:\FR\FM\12MRR1.SGM 12MRR1 8798 Federal Register / Vol. 84, No. 48 / Tuesday, March 12, 2019 / Rules and Regulations (d) Subject Air Transport Association (ATA) of America Code 35, Oxygen. (e) Reason This AD was prompted by a report of corrosion found during the manufacturing process for some oxygen pipe assemblies that are used to supply oxygen to the flight crew. This AD was also prompted by further investigation that determined affected oxygen pipes may have been installed on more airplanes than initially identified. We are issuing this AD to address corrosion of the oxygen pipe assemblies, which could lead to blocked or reduced oxygen supply to a flight crew member in case of decompression or smoke/fire in the flight deck. In addition, the presence of particles in oxygen lines, under certain conditions, increases the risk of fire in the flight deck. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Inspection for Batch Numbers and Replacement, With New Service Information This paragraph restates the requirements of paragraph (g) of AD 2015–12–08, with new service information. For airplanes identified in paragraph 1.A. of Airbus Service Bulletin A320–35–1069, dated April 26, 2013: Within 7,500 flight hours or 26 months, whichever occurs first after July 21, 2015 (the effective date of AD 2015–12–08), inspect the crew oxygen pipe, having part number (P/N) D3511032000640, to determine the batch number of that pipe, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320–35–1069, dated April 26, 2013; or Airbus Service Bulletin A320– 35–1069, Revision 03, dated December 8, 2017. A review of airplane maintenance records is acceptable in lieu of this inspection if the batch number of the pipe can be conclusively determined from that review. If the batch number of the oxygen pipe is 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 40649383, 40724994, 40820410, or 40911832: Within 7,500 flight hours or 26 months, whichever occurs first after July 21, 2015, replace the oxygen pipe with a serviceable part, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320– 35–1069, dated April 26, 2013; or Airbus Service Bulletin A320–35–1069, Revision 03, dated December 8, 2017. After the effective date of this AD, only Airbus Service Bulletin A320–35–1069, Revision 03, dated December 8, 2017, may be used to do the actions required by this paragraph. (h) Retained Inspection for Part Number and Installation Date of Crew Oxygen Pipe, With No Changes This paragraph restates the requirements of paragraph (h) of AD 2015–12–08, with no changes. For airplanes identified in paragraphs (c)(1) through (c)(4) of this AD that are not identified in paragraph 1.A. of Airbus Service Bulletin A320–35–1069, dated April 26, 2013: Within 7,500 flight VerDate Sep<11>2014 16:10 Mar 11, 2019 Jkt 247001 hours or 26 months, whichever occurs first after July 21, 2015 (the effective date of AD 2015–12–08), inspect the crew oxygen pipe to determine whether P/N D3511032000640 was installed after June 2011. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number and installation date of the pipe can be conclusively determined from that review. If the pipe was installed after June 2011, or the date cannot be conclusively determined, before further flight, do the actions required in paragraph (g) of this AD. (i) Retained Parts Installation Prohibition, With No Changes This paragraph restates the prohibition specified in paragraph (i) of AD 2015–12–08, with no changes. For airplanes identified in paragraphs (c)(1) through (c)(4) of this AD: As of July 21, 2015 (the effective date of AD 2015–12–08), do not install, on any airplane, a crew oxygen pipe P/N D3511032000640, that is identified as belonging to batch number 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 40649383, 40724994, 40820410, or 40911832. (j) New Requirement of This AD: Inspection for Batch Numbers and Replacement for Certain Airplanes For airplanes identified in paragraph (c)(5) of this AD: Within 7,500 flight hours or 26 months, whichever occurs first after the effective date of this AD, inspect the crew oxygen pipe, having P/N D3511032000640, to determine the batch number of that pipe, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320– 35–1069, Revision 03, dated December 8, 2017. A review of airplane maintenance records is acceptable in lieu of this inspection if the batch number of the pipe can be conclusively determined from that review. If the batch number of the oxygen pipe is 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 40649383, 40724994, 40820410, or 40911832: Within 7,500 flight hours or 26 months, whichever occurs first after the effective date of this AD, replace the oxygen pipe with a serviceable part, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320–35–1069, Revision 03, dated December 8, 2017. (k) New Parts Installation Prohibition for Certain Airplanes For airplanes identified in paragraph (c)(5) of this AD: As of the effective date of this AD, do not install, on any airplane, a crew oxygen pipe P/N D3511032000640, that is identified as belonging to batch number 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 40649383, 40724994, 40820410, or 40911832. (l) New No Reporting Requirement Although Airbus Service Bulletin A320– 35–1069, Revision 03, dated December 8, 2017, specifies to submit certain information to the manufacturer, and specifies that action as Required for Compliance (RC), this AD does not include that requirement.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2015-12-08, Amendment 39-18182 (80 FR 34262, 
June 16, 2015) (``AD 2015-12-08''). AD 2015-12-08 applied to all Airbus 
SAS Model A318-111, A318-112, A318-121, A318-122, A319-111, A319-112, 
A319-113, A319-114, A319-115, A319-131, A319-132, A319-133, A320-211, 
A320-212, A320-214, A320-231, A320-232, A320-233, A321-111, A320-112, 
A320-131, A320-211, A320-212, A320-213, A320-231, and A320-232 
airplanes. The NPRM published in the Federal Register on October 4, 
2018 (83 FR 50047). The NPRM was prompted by further investigation that 
determined that affected oxygen pipes may have been installed on more 
airplanes than initially identified. The NPRM proposed to revise the 
applicability to include additional airplane models and additional 
pipes to be replaced if necessary. We are issuing this AD to address 
corrosion of the oxygen pipe assemblies, which could lead to blocked or 
reduced oxygen supply to a flight crew member in case of decompression 
or smoke/fire in the flight deck. In addition, the presence of 
particles in oxygen lines, under certain conditions, increases the risk 
of fire in the flight deck.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0060R1, dated July 19, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A318 and A319 
series airplanes; all Model A320-211, A320-212, A320-214, A320-216, 
A320-231, A320-232, A320-233, A321-111, A321-112, A321-131, A321-211, 
A321-212, A321-213, A321-231, and A321-232 airplanes; and certain Model 
A320-251N, A320-271N, and A321-271N airplanes. The MCAI states:

    Some oxygen pipe assemblies were found corroded during 
manufacturing at supplier level. The affected pipe assembly was 
installed at the end of the right hand (RH) crew distribution line, 
just upstream of the First Officer and RH Observer oxygen mask 
boxes.
    The investigation showed that the affected pipes had been heat 
treated just 4 weeks before the summer factory closure and were only 
cleaned after re-opening of the factory. During this interruption, 
corrosion developed in these pipes.
    This condition, if not detected and corrected, could lead to 
blocked or reduced oxygen supply to a flight crew member in case of 
decompression or smoke/fire in the cockpit. In addition, the 
presence of particles in oxygen lines, under certain conditions, 
increases the risk of fire in the cockpit.
    The parts manufacturer identified the batch numbers of the 
potentially affected pipes that were manufactured in a specific 
period in 2011. Based on that information, Airbus identified the 
aeroplanes on which those pipes were installed on the production 
line and issued [service bulletin] SB A320-35-1069, containing 
instructions to remove the affected pipes from service.
    Consequently, EASA issued AD 2013-0278 [which corresponds to FAA 
AD 2015-12-08] to require the identification and replacement of the 
affected oxygen pipes. That [EASA] AD also prohibited installation 
of any affected pipe on other aeroplanes.
    After EASA AD 2013-0278 was issued, further investigation 
determined that affected oxygen pipes may have been installed on 
more aeroplanes than initially identified. Consequently, Airbus 
revised SB A320-35-1069 and EASA issued AD 2017-0150,

[[Page 8796]]

retaining the requirements of EASA AD 2013-0278, which was 
superseded, and requiring the same actions on these additional 
aeroplanes.
    After EASA AD 2017-0150 was issued, it was determined that five 
A320 and A321 NEO aeroplanes had been delivered with a configuration 
which potentially allows the installation of an affected oxygen 
pipe.
    Consequently, EASA issued AD 2018-0060, retaining the 
requirements of EASA AD 2017-0150, which was superseded, expanding 
the Applicability to include the five A320 and A321 NEO aeroplanes, 
and correcting the Table in Appendix 1 by removing MSN [manufacturer 
serial number] 5091 which belongs to Group 2.
    Since that AD was issued, several operator requests were 
received to clarify the required actions for Group 3 and Group 4 
aeroplanes. It was determined that, as per Airbus configuration 
control, the EASA AD No.: 2018-0060R1 affected parts have been 
identified as being potentially installed in production only on 
Group 1 and Group 2 aeroplanes. However, it is possible that those 
parts migrated to other aeroplanes during maintenance; for that 
reason, Group 3 and 4 aeroplanes need to be considered. This [EASA] 
AD is revised accordingly.

    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-2018-
0806.

Comments

    We 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

    Air Line Pilots Association, International (ALPA) stated its 
support for the NPRM.

Request To Add Airplanes to Paragraph (j) of the Proposed AD

    American Airlines requested that additional airplanes be added to 
paragraph (j) of the proposed AD. American Airlines asserted that 
Airbus has identified additional airplanes, which are included in 
Revision 02, dated October 26, 2016; and Revision 03, dated December 8, 
2017; of Airbus Service Bulletin A320-35-1069.
    We disagree with the request to add airplanes to paragraph (j) of 
this AD, which contains a new action for those airplanes not affected 
by AD 2015-12-18. The airplanes identified by the commenter are already 
included in paragraph (h) of this AD, which contains a retained action 
from AD 2015-12-18. Adding those airplanes to paragraph (j) of this AD 
would result in redundant requirements for those airplanes. We have not 
changed this AD in this regard.

Request To Specify No Reporting

    American Airlines requested that we do not require the reporting 
specified in Airbus Service Bulletin A320-35-1069, Revision 03, dated 
December 8, 2017. American Airlines stated that this action is not 
related to the unsafe condition.
    We agree with the request. We have added paragraph (l) to this AD 
to specify no reporting is required. We have redesignated subsequent 
paragraphs of this AD accordingly.

Request To Remove Location for Accomplishing a Certain Action

    American Airlines requested that we remove the location from the 
requirement to flush certain removed parts. American Airlines stated 
that Airbus Service Bulletin A320-35-1069, Revision 03, dated December 
8, 2017, specifies doing that action in the shop. American Airlines 
stated that the location of performing that maintenance action is not 
relevant to correcting the unsafe condition.
    We agree with the request for the reason provided by the commenter. 
We have added paragraph (m)(1) to this AD to specify that the location 
to flush certain parts is not required by this AD.

Request for Alternative Part Numbers

    American Airlines requested that we include alternative parts for 
washer part number (P/N) AN960C816. American Airlines stated that 
Airbus Service Bulletin A320-35-1069, Revision 03, dated December 8, 
2017, specifies to install the new crew oxygen pipe with P/N AN960C816, 
but that part number is obsolete. American Airlines stated that part 
number can be replaced with alternate P/N NAS1149C0863R, as specified 
in Illustrated Parts Catalog (IPC) 35-12-01-03, Item 110. American 
Airlines requested that we allow the installation of alternate parts as 
specified in the IPC.
    We partially agree with the commenter. We disagree to allow 
installation of any alternative part specified in the IPC because the 
IPC is not FAA-approved data. However, we agree to allow the use of 
alternate P/N NAS1149C0863R. We have added paragraph (m)(2) to this AD 
to allow the use of that alternate part number.

Clarification of Requirements for Model A320-216 Airplanes

    We stated the following in the NPRM: The Airbus SAS Model A320-216 
was type certificated on December 19, 2016. Before that date, any EASA 
AD that affected Model A320-216 airplanes was included on the Required 
Airworthiness Action List (RAAL). Model A320-216 airplanes have 
subsequently been placed on the U.S. Register, and will now be included 
in FAA AD actions. For Airbus SAS Model A320-216 airplanes, the 
requirements that correspond to AD 2015-12-08 were mandated by the MCAI 
via the RAAL. Although that RAAL requirement is still in effect, for 
continuity and clarity we have identified Airbus SAS Model A320-216 
airplanes in paragraph (c) of this AD; the restated requirements of 
paragraphs (g), (h), and (i) of this AD would therefore apply to those 
airplanes.
    However, in paragraph (i) of the NPRM, we excluded Airbus SAS Model 
A320-216 airplanes. We also included those airplanes in the new 
requirements in paragraphs (j) and (k) of the NPRM.
    We should not have excluded Airbus SAS Model A320-216 airplanes in 
paragraph (i) of the NPRM since the restated requirements of that 
paragraph still apply to those airplanes via the RAAL. Likewise, those 
airplanes should not have been included in the new requirements of 
paragraphs (j) and (k) of the NPRM because the requirements were 
already addressed by the restated requirements of paragraphs (g), (h), 
and (i) of the NPRM (which correspond to the actions required by the 
MCAI, EASA AD 2013-0278, via the RAAL). Therefore, we have removed 
references to Airbus SAS Model A320-216 airplanes from paragraphs (j) 
and (k) of this AD, and removed the text excluding Airbus SAS Model 
A320-216 from paragraph (i) of this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule 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 has issued Service Bulletin A320-35-1069, Revision 03, dated

the right-hand crew distribution line, and replacement of the pipe.
    This AD also requires Airbus Service Bulletin A320-35-1069, dated 
April 26, 2013, which the Director of the Federal Register approved for 
incorporation by reference as of July 21, 2015 (80 FR 34262, June 16, 
2015).
    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 50 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

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

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

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
5 work-hours x $85 per hour = $425....              $0             $425
------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all known costs in our cost 
estimate.

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

    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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2015-12-08, Amendment 39-18182 (80 FR 34262, June 16, 2015), and adding 
the following new AD:

2019-05-08 Airbus SAS: Amendment 39-19590; Docket No. FAA-2018-0806; 
Product Identifier 2018-NM-056-AD.

(a) Effective Date

    This AD is effective April 16, 2019.

(b) Affected ADs

    This AD replaces AD 2015-12-08, Amendment 39-18182 (80 FR 34262, 
June 16, 2015) (``AD 2015-12-08'').

(c) Applicability

    This AD applies to the Airbus SAS airplanes identified in 
paragraphs (c)(1) through (c)(5) of this AD, certificated in any 
category.
    (1) Model A318-111, -112, -121, and -122 airplanes, all 
manufacturer serial numbers.
    (2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133

[[Page 8798]]

(d) Subject

    Air Transport Association (ATA) of America Code 35, Oxygen.

(e) Reason

    This AD was prompted by a report of corrosion found during the 
manufacturing process for some oxygen pipe assemblies that are used 
to supply oxygen to the flight crew. This AD was also prompted by 
further investigation that determined affected oxygen pipes may have 
been installed on more airplanes than initially identified. We are 
issuing this AD to address corrosion of the oxygen pipe assemblies, 
which could lead to blocked or reduced oxygen supply to a flight 
crew member in case of decompression or smoke/fire in the flight 
deck. In addition, the presence of particles in oxygen lines, under 
certain conditions, increases the risk of fire in the flight deck.

(f) Compliance

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

(g) Retained Inspection for Batch Numbers and Replacement, With New 
Service Information

    This paragraph restates the requirements of paragraph (g) of AD 
2015-12-08, with new service information. For airplanes identified 
in paragraph 1.A. of Airbus Service Bulletin A320-35-1069, dated 
April 26, 2013: Within 7,500 flight hours or 26 months, whichever 
occurs first after July 21, 2015 (the effective date of AD 2015-12-
08), inspect the crew oxygen pipe, having part number (P/N) 
D3511032000640, to determine the batch number of that pipe, in 
accordance with the Accomplishment Instructions of Airbus Service 
Bulletin A320-35-1069, dated April 26, 2013; or Airbus Service 
Bulletin A320-35-1069, Revision 03, dated December 8, 2017. A review 
of airplane maintenance records is acceptable in lieu of this 
inspection if the batch number of the pipe can be conclusively 
determined from that review. If the batch number of the oxygen pipe 
is 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 
40649383, 40724994, 40820410, or 40911832: Within 7,500 flight hours 
or 26 months, whichever occurs first after July 21, 2015, replace 
the oxygen pipe with a serviceable part, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A320-35-1069, 
dated April 26, 2013; or Airbus Service Bulletin A320-35-1069, 
Revision 03, dated December 8, 2017. After the effective date of 
this AD, only Airbus Service Bulletin A320-35-1069, Revision 03, 
dated December 8, 2017, may be used to do the actions required by 
this paragraph.

(h) Retained Inspection for Part Number and Installation Date of Crew 
Oxygen Pipe, With No Changes

    This paragraph restates the requirements of paragraph (h) of AD 
2015-12-08, with no changes. For airplanes identified in paragraphs 
(c)(1) through (c)(4) of this AD that are not identified in 
paragraph 1.A. of Airbus Service Bulletin A320-35-1069, dated April 
26, 2013: Within 7,500 flight hours or 26 months, whichever occurs 
first after July 21, 2015 (the effective date of AD 2015-12-08), 
inspect the crew oxygen pipe to determine whether P/N D3511032000640 
was installed after June 2011. A review of airplane maintenance 
records is acceptable in lieu of this inspection if the part number 
and installation date of the pipe can be conclusively determined 
from that review. If the pipe was installed after June 2011, or the 
date cannot be conclusively determined, before further flight, do 
the actions required in paragraph (g) of this AD.

(i) Retained Parts Installation Prohibition, With No Changes

    This paragraph restates the prohibition specified in paragraph 
(i) of AD 2015-12-08, with no changes. For airplanes identified in 
paragraphs (c)(1) through (c)(4) of this AD: As of July 21, 2015 
(the effective date of AD 2015-12-08), do not install, on any 
airplane, a crew oxygen pipe P/N D3511032000640, that is identified 
as belonging to batch number 19356252, 40008586, 40076689, 40187414, 
40292749, 40405164, 40649383, 40724994, 40820410, or 40911832.

(j) New Requirement of This AD: Inspection for Batch Numbers and 
Replacement for Certain Airplanes

    For airplanes identified in paragraph (c)(5) of this AD: Within 
7,500 flight hours or 26 months, whichever occurs first after the 
effective date of this AD, inspect the crew oxygen pipe, having P/N 
D3511032000640, to determine the batch number of that pipe, in 
accordance with the Accomplishment Instructions of Airbus Service 
Bulletin A320-35-1069, Revision 03, dated December 8, 2017. A review 
of airplane maintenance records is acceptable in lieu of this 
inspection if the batch number of the pipe can be conclusively 
determined from that review. If the batch number of the oxygen pipe 
is 19356252, 40008586, 40076689, 40187414, 40292749, 40405164, 
40649383, 40724994, 40820410, or 40911832: Within 7,500 flight hours 
or 26 months, whichever occurs first after the effective date of 
this AD, replace the oxygen pipe with a serviceable part, in 
accordance with the Accomplishment Instructions of Airbus Service

40405164, 40649383, 40724994, 40820410, or 40911832.

(l) New No Reporting Requirement

    Although Airbus Service Bulletin A320-35-1069, Revision 03, 
dated December 8, 2017, specifies to submit certain information to 
the manufacturer, and specifies that action as Required for 
Compliance (RC), this AD does not include that requirement.

(m) Service Information Exceptions

    (1) Where Airbus Service Bulletin A320-35-1069, Revision 03, 
dated December 8, 2017, specifies the location to flush certain 
parts with nitrogen as ``in the shop,'' and specifies that location 
as RC, this AD does not require that location to be used when 
flushing the parts.
    (2) Where Airbus Service Bulletin A320-35-1069, Revision 03, 
dated December 8, 2017, specifies to use part number (P/N) 
AN960C816, and specifies that part number as RC, this AD allows the 
use of P/N NAS1149C0863R in lieu of P/N AN960C816.
