SUPPLEMENTARY INFORMATION: Discussion The FAA issued AD 2016–18–02, Amendment 39–18632 (81 FR 59834, August 31, 2016) (‘‘AD 2016–18–02’’), for certain The Boeing Company Model 777–200 and –300ER series airplanes. AD 2016–18–02 required replacing the low-pressure oxygen flex hoses with new non-conductive low-pressure oxygen flex hoses in the gaseous passenger oxygen system in airplanes equipped with therapeutic oxygen. AD PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 449 2016–18–02 resulted from a determination that the low-pressure oxygen flex hoses in the gaseous passenger oxygen system can potentially be conductive. The FAA issued AD 2016–18–02 to address the potential for electrical current to pass through the low-pressure oxygen flex hoses in the gaseous passenger oxygen system, which can cause the flex hoses to melt or burn and result in an oxygen-fed fire in the passenger cabin. Actions Since AD 2016–18–02 Was Issued Since AD 2016–18–02 was issued, the FAA has been advised that the required service information omitted certain instructions for Group 4 airplanes. Related Service Information Under 1 CFR Part 51 The FAA reviewed Boeing Special Attention Service Bulletin 777–35– 0041, Revision 1, dated August 14, 2019. This service information describes procedures for replacing the lowpressure oxygen flex hoses with new non-conductive low-pressure oxygen flex hoses in the gaseous passenger oxygen system in airplanes equipped with therapeutic oxygen. This service information adds instructions (i.e., Figures 6 and 10) that had previously been omitted for certain airplanes (i.e., Group 4). This AD requires Boeing Special Attention Service Bulletin 777–35– 0041, dated April 8, 2016, which the Director of the Federal Register approved for incorporation by reference as of September 15, 2016 (81 FR 59834, August 31, 2016). 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. FAA’s Determination The FAA is issuing this AD because the agency evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements Although this AD does not explicitly restate the requirements of AD 2016– 18–02, this AD retains the requirements of AD 2016–18–02. Those requirements are referenced in the service information identified previously, which, in turn, is referenced in paragraph (g) of this AD. For certain airplanes, this AD adds actions that were omitted from the previous service information. This AD requires accomplishment of the actions E:\FR\FM\06JAR1.SGM 06JAR1 450 Federal Register / Vol. 85, No. 3 / Monday, January 6, 2020 / Rules and Regulations identified as ‘‘RC’’ (required for compliance) in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777–35–0041, Revision 1, dated August 14, 2019, described previously. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 0983. FAA’s Justification and Determination of the Effective Date There are currently no domestic operators of these products. Therefore, the FAA finds that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, the FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2019–0983 and Product Identifier 2019–NM–171–AD at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. The FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact received about this final rule. Costs of Compliance Currently, there are no affected U.S.registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, the following are the cost estimates to comply with this AD: lotter on DSKBCFDHB2PROD with RULES ESTIMATED COSTS Action Labor cost Parts cost Replacement (actions retained from AD 2016– 18–02). New actions for Group 4, Configuration 2 airplanes. Up to 33 work-hours × $85 per hour = Up to $2,805. 6 work-hours × $85 per hour = $510 ................... Up to $15,173 ........ Up to $17,978. $0 ........................... $510. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all costs in the cost estimate. 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. Authority for This Rulemaking Regulatory Findings 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 The FAA has 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) 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 AD 2016-18-02, Amendment 39-18632 (81 FR 59834, 
August 31, 2016) (``AD 2016-18-02''), for certain The Boeing Company 
Model 777-200 and -300ER series airplanes. AD 2016-18-02 required 
replacing the low-pressure oxygen flex hoses with new non-conductive 
low-pressure oxygen flex hoses in the gaseous passenger oxygen system 
in airplanes equipped with therapeutic oxygen. AD 2016-18-02 resulted 
from a determination that the low-pressure oxygen flex hoses in the 
gaseous passenger oxygen system can potentially be conductive. The FAA 
issued AD 2016-18-02 to address the potential for electrical current to 
pass through the low-pressure oxygen flex hoses in the gaseous 
passenger oxygen system, which can cause the flex hoses to melt or burn 
and result in an oxygen-fed fire in the passenger cabin.

Actions Since AD 2016-18-02 Was Issued

    Since AD 2016-18-02 was issued, the FAA has been advised that the 
required service information omitted certain instructions for Group 4 
airplanes.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Special Attention Service Bulletin 777-35-
0041, Revision 1, dated August 14, 2019. This service information 
describes procedures for replacing the low-pressure oxygen flex hoses 
with new non-conductive low-pressure oxygen flex hoses in the gaseous 
passenger oxygen system in airplanes equipped with therapeutic oxygen. 
This service information adds instructions (i.e., Figures 6 and 10) 
that had previously been omitted for certain airplanes (i.e., Group 4).
    This AD requires Boeing Special Attention Service Bulletin 777-35-
0041, dated April 8, 2016, which the Director of the Federal Register 
approved for incorporation by reference as of September 15, 2016 (81 FR 
59834, August 31, 2016).
    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.

FAA's Determination

    The FAA is issuing this AD because the agency evaluated all the 
relevant information and determined the unsafe condition described 
previously is likely to exist or develop in other products of the same 
type design.

AD Requirements

    Although this AD does not explicitly restate the requirements of AD 
2016-18-02, this AD retains the requirements of AD 2016-18-02. Those 
requirements are referenced in the service information identified 
previously, which, in turn, is referenced in paragraph (g) of this AD. 
For certain airplanes, this AD adds actions that were omitted from the 
previous service information. This AD requires accomplishment of the 
actions

identified as ``RC'' (required for compliance) in the Accomplishment 
Instructions of Boeing Special Attention Service Bulletin 777-35-0041, 
Revision 1, dated August 14, 2019, described previously. For 
information on the procedures and compliance times, see this service 
information at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2019-0983.

FAA's Justification and Determination of the Effective Date

    There are currently no domestic operators of these products. 
Therefore, the FAA finds that notice and opportunity for prior public 
comment are unnecessary and that good cause exists for making this 
amendment effective in less than 30 days.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, the following are the cost estimates to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
             Action                    Labor cost               Parts cost                 Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement (actions retained     Up to 33 work-hours  Up to $15,173...............  Up to $17,978.
 from AD 2016-18-02).              x $85 per hour =
                                   Up to $2,805.
New actions for Group 4,          6 work-hours x $85   $0..........................  $510.
 Configuration 2 airplanes.        per hour = $510.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. The FAA does not control warranty coverage for affected 
individuals. As a result, the FAA has included all costs in the 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.
    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

    The FAA has 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) 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.

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) 
2016-18-02, Amendment 39-18632 (81 FR 59834, August 31, 2016), and 
adding the following new AD:

2019-25-12 The Boeing Company: Amendment 39-21010; Docket No. FAA-
2019-0983; Product Identifier 2019-NM-171-AD.

(a) Effective Date

    This AD is effective January 21, 2020.

(b) Affected ADs

    This AD replaces AD 2016-18-02, Amendment 39-18632 (81 FR 59834, 
August 31, 2016) (``AD 2016-18-02'').

(c) Applicability

    This AD applies to The Boeing Company Model 777-200 and -300ER 
series airplanes, certificated in any category, as identified in 
Boeing Special Attention Service Bulletin 777-35-0041, Revision 1, 
dated August 14, 2019.

(d) Subject

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

[[Page 451]]

(e) Unsafe Condition

    This AD was prompted by the determination that the low-pressure 
oxygen flex hoses in the gaseous passenger oxygen system can 
potentially be conductive. The FAA is issuing this AD to address the 
potential for electrical current to pass through the low-pressure 
oxygen flex hoses in the gaseous passenger oxygen system, which can 
cause the flex hoses to melt or burn and result in an oxygen-fed 
fire in the passenger cabin.

(f) Compliance

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

(g) Replacement Actions

    Within 72 months after September 15, 2016 (the effective date of 
AD 2016-18-02): Do all applicable actions identified as ``RC'' 
(required for compliance) in, and in accordance with, paragraph 
(g)(1) or (2) of this AD, as applicable.
    (1) Except as required by paragraph (g)(2) of this AD: Do the 
actions in accordance with the Accomplishment Instructions of Boeing 
Special Attention Service Bulletin 777-35-0041, dated April 8, 2016; 
or Revision 1, dated August 14, 2019.
    (2) For airplanes identified as Group 4 in Boeing Special 
Attention Service Bulletin 777-35-0041, Revision 1, dated August 14, 
2019: Do the actions in accordance with the Accomplishment 
Instructions of Boeing Special Attention Service Bulletin 777-35-
0041, Revision 1, dated August 14, 2019.

(h) Parts Installation Prohibition

    As of September 15, 2016 (the effective date of AD 2016-18-02), 
no person may install on any airplane a low-pressure oxygen flex 
hose having a part number that is specified to be removed from an 
airplane in the Accomplishment Instructions of Boeing Special 
Attention Service Bulletin 777-35-0041, Revision 1, dated August 14, 
2019.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle ACO 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 
manager of the ACO, send it to the attention of the person 
identified in paragraph (j) of this AD. Information may be emailed 
to: [email protected].
    (2) 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.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Seattle 
ACO, FAA, to make those findings. To be approved, the repair method, 
modification deviation, or alteration deviation must meet the 
certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) AMOCs approved previously for AD 2016-18-02 are approved as 
AMOCs for the corresponding provisions of paragraph (g) of this AD.
    (5) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(i)(5)(i) and (ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled 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 RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
