SUPPLEMENTARY INFORMATION: amozie on DSK3GDR082PROD with RULES Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. The NPRM published in the Federal Register on April 16, 2018 (83 FR 16243). The NPRM was prompted by a report indicating that during a fleet survey on a retired Model 737 airplane, cracking was found common to the number 3 windshield assembly, aft sill web. The NPRM proposed to require, at certain locations, repetitive HFEC inspections of the number 3 windshield assembly, aft sill web; and applicable on-condition actions. We are issuing this AD to address such cracking common to the number 3 windshield assembly, aft sill web, which could adversely affect the structural integrity of the windshield assembly. 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. VerDate Sep<11>2014 16:35 Aug 29, 2018 Jkt 244001 Effect of Winglets on Accomplishment of the Proposed Actions Aviation Partners Boeing stated that accomplishing the Supplemental Type Certificate (STC) ST01219SE does not affect the actions specified in the NPRM. We agree with the commenter. We have redesignated paragraph (c) of the proposed AD as paragraph (c)(1) of this AD and added paragraph (c)(2) to this AD to state that installation of STC ST01219SE does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01219SE is installed, a ‘‘change in product’’ alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17. Request To Clarify Inspection Location Boeing requested that the language in the ‘‘Related Service Information under 1 CFR part 51’’ paragraph be clarified in the proposed AD. Boeing requested that we replace ‘‘repetitive HFEC inspections of the number 3 windshield and of the aft sill web’’ with ‘‘repetitive HFEC inspections of the number 3 windshield aft sill web.’’ Boeing stated that there is no requirement in Boeing Alert Requirements Bulletin 737–53A1377 RB, dated December 11, 2017, to inspect the windshield with an HFEC inspection. Boeing commented that the only HFEC requirement in Boeing Alert Requirements Bulletin 737–53A1377 RB, dated December 11, 2017, is to accomplish the HFEC inspections of the number 3 windshield aft sill web. We agree with the request to clarify the inspection location, for the reasons provided. We have revised the ‘‘Summary and Related Service Information under 1 CFR part 51’’ section, as well as the SUMMARY, of this final rule accordingly. For consistency within this AD and in response to the following Boeing comment, this AD specifies the ‘‘number 3 windshield assembly, aft sill web.’’ Request To Clarify Location of Cracking Boeing requested that we clarify the unsafe condition in paragraph (e) of the NPRM. Boeing requested that we replace the language ‘‘common to the windshield and aft sill web’’ with ‘‘common to the number 3 windshield assembly, aft sill web.’’ Boeing stated that the cracking in the aft sill web is at the fastener common to the aft sill web and the outer chord of the number 3 windshield assembly and is not actually common to the windshield. We agree with the request, for the reasons provided. We have revised PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 paragraph (e) of this AD, as well as the and the Discussion section of this final rule, accordingly. SUMMARY Request To Clarify Certain Language in the ‘‘Exceptions to Service Information Specifications’’ Paragraph Boeing requested that we revise paragraph (i)(2) of the ‘‘Exceptions to Service Information Specifications’’ paragraph in the proposed AD. Boeing requested that we replace the language ‘‘specifies contacting Boeing’’ with ‘‘specifies contacting Boeing for repair instructions.’’ Boeing commented that this addition adds clarity. We agree with the request and have revised this AD to clarify the requirements accordingly. Explanation of Change to Applicability Description The applicability of the proposed AD referred to affected airplanes identified in Boeing Alert Requirements Bulletin 737–53A1377 RB, dated December 11, 2017. The effectivity in the service information is identified in terms of line numbers. Since those line numbers include all airplanes of the affected models, we have revised the applicability in this AD as all Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. 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 We reviewed Boeing Alert Requirements Bulletin 737–53A1377 RB, dated December 11, 2017. The service information describes procedures for repetitive HFEC inspections of the number 3 windshield assembly, aft sill web at station 254.6, between stringers S–9 and S–11 on the left- and right-hand sides; and applicable on-condition actions. This service information is reasonably available because the interested parties E:\FR\FM\30AUR1.SGM 30AUR1 Federal Register / Vol. 83, No. 169 / Thursday, August 30, 2018 / Rules and Regulations Costs of Compliance have access to it through their normal course of business or by the means identified in the ADDRESSES section. We estimate that this AD affects 63 airplanes of U.S. registry. We estimate 44201 the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost HFEC inspection ......... 4 work-hours × $85 per hour = $340 per inspection cycle. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division. amozie on DSK3GDR082PROD with RULES Regulatory Findings This AD will not have federalism implications under Executive Order 13132.

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 SAS Model A319–115 and –132 airplanes, and Model A320–214, –216, –232, and –233 airplanes. The NPRM published in the Federal Register on May 15, 2018 (83 FR 22426). The NPRM was prompted by a report indicating that certain modified airplanes do not have electrical ground wires on the FLSCU, which adversely affects the fuel gravity feeding operation. The NPRM proposed to require modification of the FLSCU wiring. We are issuing this AD to address reduced fuel pressure at the engine inlet, potentially resulting in an uncommanded in-flight shutdown when flying at the fuel gravity feed ceiling levels. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017–0216, dated October 30, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus SAS Model A319–115 and –132 airplanes, and Model A320– 214, –216, –232, and –233 airplanes. The MCAI states: Airbus introduced mod 154327 on A319 and A320 aeroplanes which substituted the pump fuel feed system from the centre fuel tank with a jet pump transfer system, based on the Airbus A321 design. Following the modification introduction, it was discovered that the modified aeroplanes do not have electrical ground signals that replicate those from the deleted centre tank pump pressure E:\FR\FM\30AUR1.SGM 30AUR1

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 The Boeing Company 
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The 
NPRM published in the Federal Register on April 16, 2018 (83 FR 16243). 
The NPRM was prompted by a report indicating that during a fleet survey 
on a retired Model 737 airplane, cracking was found common to the 
number 3 windshield assembly, aft sill web. The NPRM proposed to 
require, at certain locations, repetitive HFEC inspections of the 
number 3 windshield assembly, aft sill web; and applicable on-condition 
actions.
    We are issuing this AD to address such cracking common to the 
number 3 windshield assembly, aft sill web, which could adversely 
affect the structural integrity of the windshield assembly.

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.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that accomplishing the Supplemental 
Type Certificate (STC) ST01219SE does not affect the actions specified 
in the NPRM.
    We agree with the commenter. We have redesignated paragraph (c) of 
the proposed AD as paragraph (c)(1) of this AD and added paragraph 
(c)(2) to this AD to state that installation of STC ST01219SE does not 
affect the ability to accomplish the actions required by this AD. 
Therefore, for airplanes on which STC ST01219SE is installed, a 
``change in product'' alternative method of compliance (AMOC) approval 
request is not necessary to comply with the requirements of 14 CFR 
39.17.

Request To Clarify Inspection Location

    Boeing requested that the language in the ``Related Service 
Information under 1 CFR part 51'' paragraph be clarified in the 
proposed AD. Boeing requested that we replace ``repetitive HFEC 
inspections of the number 3 windshield and of the aft sill web'' with 
``repetitive HFEC inspections of the number 3 windshield aft sill 
web.'' Boeing stated that there is no requirement in Boeing Alert 
Requirements Bulletin 737-53A1377 RB, dated December 11, 2017, to 
inspect the windshield with an HFEC inspection. Boeing commented that 
the only HFEC requirement in Boeing Alert Requirements Bulletin 737-
53A1377 RB, dated December 11, 2017, is to accomplish the HFEC 
inspections of the number 3 windshield aft sill web.
    We agree with the request to clarify the inspection location, for 
the reasons provided. We have revised the ``Summary and Related Service 
Information under 1 CFR part 51'' section, as well as the SUMMARY, of 
this final rule accordingly. For consistency within this AD and in 
response to the following Boeing comment, this AD specifies the 
``number 3 windshield assembly, aft sill web.''

Request To Clarify Location of Cracking

    Boeing requested that we clarify the unsafe condition in paragraph 
(e) of the NPRM. Boeing requested that we replace the language ``common 
to the windshield and aft sill web'' with ``common to the number 3 
windshield assembly, aft sill web.'' Boeing stated that the cracking in 
the aft sill web is at the fastener common to the aft sill web and the 
outer chord of the number 3 windshield assembly and is not actually 
common to the windshield.
    We agree with the request, for the reasons provided. We have 
revised paragraph (e) of this AD, as well as the SUMMARY and the 
Discussion section of this final rule, accordingly.

Request To Clarify Certain Language in the ``Exceptions to Service 
Information Specifications'' Paragraph

    Boeing requested that we revise paragraph (i)(2) of the 
``Exceptions to Service Information Specifications'' paragraph in the 
proposed AD. Boeing requested that we replace the language ``specifies 
contacting Boeing'' with ``specifies contacting Boeing for repair 
instructions.'' Boeing commented that this addition adds clarity.
    We agree with the request and have revised this AD to clarify the 
requirements accordingly.

Explanation of Change to Applicability Description

    The applicability of the proposed AD referred to affected airplanes 
identified in Boeing Alert Requirements Bulletin 737-53A1377 RB, dated 
December 11, 2017. The effectivity in the service information is 
identified in terms of line numbers. Since those line numbers include 
all airplanes of the affected models, we have revised the applicability 
in this AD as all Model 737-100, -200, -200C, -300, -400, and -500 
series airplanes.

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

    We reviewed Boeing Alert Requirements Bulletin 737-53A1377 RB, 
dated December 11, 2017. The service information describes procedures 
for repetitive HFEC inspections of the number 3 windshield assembly, 
aft sill web at station 254.6, between stringers S-9 and S-11 on the 
left- and right-hand sides; and applicable on-condition actions. This 
service information is reasonably available because the interested 
parties

[[Page 44201]]

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 63 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                Cost on U.S.
             Action                     Labor cost        Parts cost    Cost per product          operators

                                   per hour = $340 per                 cycle.                inspection cycle.
                                   inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.
