Bragg, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; phone ddrumheller on DSK120RN23PROD with RULES1 SUMMARY: VerDate Sep<11>2014 16:01 Jul 28, 2023 Jkt 259001 817–222–5366; email: joshua.k.bragg@ faa.gov. SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Embraer S.A. Model ERJ 170 airplanes. The NPRM published in the Federal Register on September 15, 2022 (87 FR 56598). The NPRM was prompted by AD 2022–04–01, effective April 29, 2022, issued by ANAC, which is the aviation authority for Brazil (ANAC AD 2022–04–01) (also referred to as the MCAI). The MCAI states that certain flight control electrical harnesses were routed incorrectly, providing inadequate separation from other electrical harness installations. In the NPRM, the FAA proposed to require inspecting certain flight control electrical harnesses for incorrect routing, and modifying any incorrect electrical harness installations, as specified in ANAC AD 2022–04–01. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1163. The FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Embraer S.A. Model ERJ 170 airplanes. The SNPRM published in the Federal Register on February 24, 2023 (88 FR 11830). The SNPRM was prompted by reports indicating that certain flight control electrical harnesses were routed incorrectly, providing inadequate separation from other electrical harness installations. In the SNPRM, the FAA proposed to require inspecting certain flight control electrical harnesses for incorrect routing, and modifying any incorrect electrical harness installations. The FAA is issuing this AD to address the incorrect routing of flight control electrical harnesses near critical fuel quantity indication harnesses, which could possibly result in fuel tank ignition and subsequent loss of the airplane. Discussion of Final Airworthiness Directive Comments The FAA received a comment from Air Line Pilots Association, International (ALPA), who supported the SNPRM without change. The FAA received additional comments from two commenters, including Embraer and Horizon Air. The following presents the comments received on the SNPRM and the FAA’s response to each comment. PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Requests for Increased Compliance Time and Later Date for Correction Embraer requested that the FAA allow an increase in the compliance time and to allow the correction to be done at a later date. According to Embraer, because this inspection and subsequent correction of the wiring harnesses cannot fit within a basic check, operators plan to add it to the heavy maintenance visits, during which these accesses are already open. However, the service information and the proposed AD do not allow for inspecting to be done at one opportunity and correction to be done at a later date. The FAA does not agree to the requests to revise the compliance time and allow correction to be done later. ANAC, as the state of design authority, conducted a safety analysis and determined that a 12-month compliance time is appropriate to mitigate the identified unsafe condition and did not allow for correction to be done later. The FAA concurs with ANAC’s assessment. However, under the provisions specified in paragraph (i)(1) of this AD, operators may request an alternative method of compliance (AMOC) to use a different compliance time, if the proposed AMOC provides an acceptable level of safety. This AD has not been changed with regard to this request. Request To Increase the Estimated Work-Hours Embraer requested an increase in the total number of estimated work-hours for the required actions. The commenter noted that the actual work-hours required for the actions have proven to be greater than the estimate given in the proposed AD. The FAA agrees with the request because the agency has determined that the total work-hours required exceed the previous estimate. The FAA has increased the estimated total workhours from 8 to 16. Request To Correct Typographical Error Horizon Air requested that a correction be made in paragraph (i)(3) of the proposed AD. The commenter noted that the reference to paragraph (j)(3)(i) should be to paragraph (i)(3)(i). The FAA agrees with the request. The FAA has corrected the typographical error in this AD. Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of E:\FR\FM\31JYR1.SGM 31JYR1 Federal Register / Vol. 88, No. 145 / Monday, July 31, 2023 / Rules and Regulations Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the SNPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 ANAC AD 2022–04–01R1 specifies procedures for inspecting the installation of flight control electrical harnesses W126 and W127 for incorrect routing and modifying any incorrect electrical harness installations. This 49279 material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES. Costs of Compliance The FAA estimates that this AD affects 701 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 6 work-hours × $85 per hour = $510 .......................................................................................... $0 $510 $357,510 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 10 work-hours × $85 per hour = $850 .................................................................................................................... $0 $850 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. ddrumheller on DSK120RN23PROD with RULES1 This AD will not have federalism implications under Executive Order 13132.

ACTION: Final rule.

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

[[Page 49278]]

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by 
reports indicating that certain flight control electrical harnesses 
were routed incorrectly, providing inadequate separation from other 
electrical harness installations. This AD requires an inspection of 
certain flight control electrical harnesses for incorrect routing, and 
modifying any incorrect electrical harness installations, as specified 
in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, 
which is incorporated by reference. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective September 5, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 5, 
2023.

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Embraer S.A. 
Model ERJ 170 airplanes. The NPRM published in the Federal Register on 
September 15, 2022 (87 FR 56598). The NPRM was prompted by AD 2022-04-
01, effective April 29, 2022, issued by ANAC, which is the aviation 
authority for Brazil (ANAC AD 2022-04-01) (also referred to as the 
MCAI). The MCAI states that certain flight control electrical harnesses 
were routed incorrectly, providing inadequate separation from other 
electrical harness installations.
    In the NPRM, the FAA proposed to require inspecting certain flight 
control electrical harnesses for incorrect routing, and modifying any 
incorrect electrical harness installations, as specified in ANAC AD 
2022-04-01.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1163.
    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 by adding an AD that would apply to certain 
Embraer S.A. Model ERJ 170 airplanes. The SNPRM published in the 
Federal Register on February 24, 2023 (88 FR 11830). The SNPRM was 
prompted by reports indicating that certain flight control electrical 
harnesses were routed incorrectly, providing inadequate separation from 
other electrical harness installations. In the SNPRM, the FAA proposed 
to require inspecting certain flight control electrical harnesses for 
incorrect routing, and modifying any incorrect electrical harness 
installations. The FAA is issuing this AD to address the incorrect 
routing of flight control electrical harnesses near critical fuel 
quantity indication harnesses, which could possibly result in fuel tank 
ignition and subsequent loss of the airplane.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International (ALPA), who supported the SNPRM without change.
    The FAA received additional comments from two commenters, including 
Embraer and Horizon Air. The following presents the comments received 
on the SNPRM and the FAA's response to each comment.

Requests for Increased Compliance Time and Later Date for Correction

    Embraer requested that the FAA allow an increase in the compliance 
time and to allow the correction to be done at a later date. According 
to Embraer, because this inspection and subsequent correction of the 
wiring harnesses cannot fit within a basic check, operators plan to add 
it to the heavy maintenance visits, during which these accesses are 
already open. However, the service information and the proposed AD do 
not allow for inspecting to be done at one opportunity and correction 
to be done at a later date.
    The FAA does not agree to the requests to revise the compliance 
time and allow correction to be done later. ANAC, as the state of 
design authority, conducted a safety analysis and determined that a 12-
month compliance time is appropriate to mitigate the identified unsafe 
condition and did not allow for correction to be done later. The FAA 
concurs with ANAC's assessment. However, under the provisions specified 
in paragraph (i)(1) of this AD, operators may request an alternative 
method of compliance (AMOC) to use a different compliance time, if the 
proposed AMOC provides an acceptable level of safety. This AD has not 
been changed with regard to this request.

Request To Increase the Estimated Work-Hours

    Embraer requested an increase in the total number of estimated 
work-hours for the required actions. The commenter noted that the 
actual work-hours required for the actions have proven to be greater 
than the estimate given in the proposed AD.
    The FAA agrees with the request because the agency has determined 
that the total work-hours required exceed the previous estimate. The 
FAA has increased the estimated total work-hours from 8 to 16.

Request To Correct Typographical Error

    Horizon Air requested that a correction be made in paragraph (i)(3) 
of the proposed AD. The commenter noted that the reference to paragraph 
(j)(3)(i) should be to paragraph (i)(3)(i).
    The FAA agrees with the request. The FAA has corrected the 
typographical error in this AD.

Conclusion

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of

[[Page 49279]]

Design Authority, it has notified the FAA of the unsafe condition 
described in the MCAI referenced above. The FAA reviewed the relevant 
data, considered the comments received, and determined that air safety 
requires adopting this AD as proposed. Accordingly, the FAA is issuing 
this AD to address the unsafe condition on this product. Except for 
minor editorial changes, and any other changes described previously, 
this AD is adopted as proposed in the SNPRM. None of the changes will 
increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2022-04-01R1 specifies procedures for inspecting the 
installation of flight control electrical harnesses W126 and W127 for 
incorrect routing and modifying any incorrect electrical harness 
installations. This material is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 701 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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

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

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                 Estimated Costs of On-Condition Actions

                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
10 work-hours x $85 per hour = $850...              $0             $850
------------------------------------------------------------------------

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.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
