SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2019–25–16, Amendment 39–21015 (85 FR 453, January 6, 2020) (AD 2019–25–16). AD 2019–25–16 applied to certain Embraer S.A. Model ERJ 170–100 LR, –100 STD, –100 SE, and –100 SU airplanes; and Model ERJ 170–200 LR, –200 SU, –200 STD, and 200 LL airplanes. AD 2019– 25–16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations; and added airplanes to the applicability. The FAA issued AD 2019–25–16 to address fatigue cracking of various principal structural elements (PSEs); such cracking could result in reduced structural integrity of the airplane and to prevent safety significant latent failures; such failures, in combination with one or more other specified failures or events, could result in a hazardous or catastrophic failure condition of avionics, hydraulic systems, fire detection systems, fuel systems, or other critical systems. Furthermore, the FAA issued AD 2019– 25–16 to address potential ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions; such failures, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. The NPRM published in the Federal Register on July 28, 2022 (87 FR 45284). The NPRM was prompted by AD 2022– 02–01, effective February 9, 2022, issued by ANAC (referred to after this as the MCAI) (ANAC AD 2022–02–01). The MCAI states that it was prompted by a determination that new or more restrictive airworthiness limitations are necessary. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–0979. In the NPRM, the FAA proposed to continue to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations and certain structural modifications, as specified in ANAC AD 2022–02–01. The FAA is issuing this AD to address the unsafe condition on these products. PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 Discussion of Final Airworthiness Directive Comments The FAA received a comment from Horizon Air. The following presents the comment received on the NPRM and the FAA’s response. Request To Update the Required Service Information Horizon Air requested that the Embraer 170/175 Maintenance Review Board Report, MRB 1621, Revision 17, dated July 01, 2021, referenced in ANAC AD 2022–02–01, be updated to Embraer 170/175 Maintenance Review Board Report, MRB 1621, Revision 18, dated July 4, 2022. The FAA confirms that it intends to allow the use of applicable later MRB revisions to comply with the requirements of this AD. This AD refers to ANAC AD 2022–02–01 as the appropriate source of service information for accomplishing the required actions. Paragraph (f) of ANAC AD 2022–02–01 accepts the use of later approved revisions of the referenced MRB document for compliance. Therefore, applicable later approved MRB revisions are acceptable for compliance with this AD. No change to the AD is required. 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 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 comment 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, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 ANAC AD 2022–02–01 describes new or more restrictive airworthiness limitations for airplane structures and the incorporation of certain structural modifications (i.e., reinforcement of lefthand (LH) and right-hand (RH) wing spar II lower; and reinforcement of the wing lower skin chordwise splices of LH and RH wing) before the defined structural modifications points (SMP). This AD also requires Appendix A— Airworthiness Limitations of EMBRAER E:\FR\FM\19DER1.SGM 19DER1 Federal Register / Vol. 87, No. 242 / Monday, December 19, 2022 / Rules and Regulations 170/175 Maintenance Review Board Report (MRBR), MRB–1621, Revision 14, dated September 27, 2018; and Embraer Temporary Revision (TR) 14–1, dated November 13, 2018, to Part 4-LifeLimited Items, of Appendix A of EMBRAER 170/175 Maintenance Review Board Report (MRBR), MRB– 1621, Revision 14, dated September 27, 2018; which the Director of the Federal Register approved for incorporation by reference as of February 10, 2020 (85 FR 453). 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 the ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 662 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: The FAA estimates the total cost per operator for the retained actions from AD 2019–25–16 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the existing maintenance or inspection 77495 program takes an average of 90 workhours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. The FAA estimates the total cost per operator for the new revision to the existing maintenance or inspection program to be $7,650 (90 work-hours x $85 per work-hour). ESTIMATED COSTS FOR REQUIRED ACTIONS * Action Labor cost Parts cost Cost per product Cost on U.S. operators New proposed actions .................................... 196 work-hours × $85 per hour = $16,660 .... $98,860 $115,520 $76,474,240 * Table does not include estimated costs for revising the existing maintenance or inspection program. 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 operators. The FAA does not control warranty coverage for affected operators. As a result, the FAA has included all known 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. tkelley on DSK125TN23PROD with RULES 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. 17:05 Dec 16, 2022 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2020–18–04, Amendment 39–21225 (85 FR 54896, September 3, 2020) (AD 2020–18–04). AD 2020–18–04 applied to all Airbus SAS Model A350–941 and –1041 airplanes. AD 2020–18–04 required a one-time health check of the slat PCU TSU for discrepancies, and corrective actions if necessary; a detailed inspection of the LH and RH slat transmission systems for discrepancies, and corrective actions if necessary; and PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 77497 LH and RH track 12 SGRA water drainage and vent plug cleaning (which includes an inspection for moisture). The FAA issued AD 2020–18–04 to address a slat system jam during landing phase which could lead to a double shaft disconnection or rupture, potentially causing one or more slat surfaces to be no longer connected to either the slat wing tip brake or the slat PCU, possibly resulting in reduced control of the airplane. The NPRM published in the Federal Register on September 30, 2021 (86 FR 54136). The NPRM was prompted by AD 2021–0053R1, dated April 19, 2021, issued by European Union Aviation Safety Agency (referred to after this as the MCAI). The MCAI states that since EASA AD 2020–0163R1, dated August 7, 2020 (which corresponds to FAA AD 2020–18–04), was issued, EASA received information that prompted it to add a requirement for repetitive TSU health checks, introduce a definition of serviceable part to clarify actions that have to be accomplished on affected parts, and remove a requirement for a water drainage and vent plug cleaning of the LH and RH track 12 SGRA. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2021–0833. In the NPRM, the FAA proposed to remove a requirement for water drainage and vent plug cleaning of the SGRA, require repetitive health checks of the slat PCU TSU, a detailed visual inspection of the slat transmission systems, and corrective actions if necessary, as specified in EASA AD 2020–0163R1. The FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2020–18–04. The SNPRM published in the Federal Register on June 1, 2022 (87 FR 33076) (the SNPRM). The SNPRM was prompted by EASA issuance of AD 2021–0275, dated December 10, 2021, (EASA AD 2021– 0275), which determined that requiring modification of the PCU by replacing each affected slat PCU with a serviceable PCU (one having a different part number) is necessary, and clarified the limitations related to when an affected slat PCU may be installed on an airplane. In the SNPRM, the FAA proposed to require modification (replacement of each affected slat PCU with a slat PCU having a different part number), requiring an inspection report, and revising the limitations on the installation of affected parts. The FAA is issuing this AD to address a slat system jam during landing, which could lead to a double shaft disconnection/ rupture, potentially causing one or more E:\FR\FM\19DER1.SGM 19DER1

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-25-16, Amendment 39-21015 (85 FR 453, 
January 6, 2020) (AD 2019-25-16). AD 2019-25-16 applied to certain 
Embraer S.A. Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU 
airplanes; and Model ERJ 170-200 LR, -200 SU, -200 STD, and 200 LL 
airplanes. AD 2019-25-16 required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations; and added airplanes to the 
applicability. The FAA issued AD 2019-25-16 to address fatigue cracking 
of various principal structural elements (PSEs); such cracking could 
result in reduced structural integrity of the airplane and to prevent 
safety significant latent failures; such failures, in combination with 
one or more other specified failures or events, could result in a 
hazardous or catastrophic failure condition of avionics, hydraulic 
systems, fire detection systems, fuel systems, or other critical 
systems. Furthermore, the FAA issued AD 2019-25-16 to address potential 
ignition sources inside fuel tanks caused by latent failures, 
alterations, repairs, or maintenance actions; such failures, in 
combination with flammable fuel vapors, could result in fuel tank 
explosions and consequent loss of the airplane.
    The NPRM published in the Federal Register on July 28, 2022 (87 FR 
45284). The NPRM was prompted by AD 2022-02-01, effective February 9, 
2022, issued by ANAC (referred to after this as the MCAI) (ANAC AD 
2022-02-01). The MCAI states that it was prompted by a determination 
that new or more restrictive airworthiness limitations are necessary.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-0979.
    In the NPRM, the FAA proposed to continue to require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations and 
certain structural modifications, as specified in ANAC AD 2022-02-01. 
The FAA is issuing this AD to address the unsafe condition on these 
products.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Horizon Air. The following presents 
the comment received on the NPRM and the FAA's response.

Request To Update the Required Service Information

    Horizon Air requested that the Embraer 170/175 Maintenance Review 
Board Report, MRB 1621, Revision 17, dated July 01, 2021, referenced in 
ANAC AD 2022-02-01, be updated to Embraer 170/175 Maintenance Review 
Board Report, MRB 1621, Revision 18, dated July 4, 2022.
    The FAA confirms that it intends to allow the use of applicable 
later MRB revisions to comply with the requirements of this AD. This AD 
refers to ANAC AD 2022-02-01 as the appropriate source of service 
information for accomplishing the required actions. Paragraph (f) of 
ANAC AD 2022-02-01 accepts the use of later approved revisions of the 
referenced MRB document for compliance. Therefore, applicable later 
approved MRB revisions are acceptable for compliance with this AD. No 
change to the AD is required.

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 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 
comment 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, 
this AD is adopted as proposed in the NPRM. None of the changes will 
increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2022-02-01 describes new or more restrictive airworthiness 
limitations for airplane structures and the incorporation of certain 
structural modifications (i.e., reinforcement of left-hand (LH) and 
right-hand (RH) wing spar II lower; and reinforcement of the wing lower 
skin chordwise splices of LH and RH wing) before the defined structural 
modifications points (SMP).
    This AD also requires Appendix A--Airworthiness Limitations of 
EMBRAER

    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 the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 662 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2019-25-16 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate.
    The FAA estimates the total cost per operator for the new revision 
to the existing maintenance or inspection program to be $7,650 (90 
work-hours x $85 per work-hour).

* Table does not include estimated costs for revising the existing maintenance or inspection program.

    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 operators. The FAA does not control warranty coverage for 
affected operators. As a result, the FAA has included all known 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.

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.

    This paragraph restates the requirements of paragraph (j) of AD 
2019-25-16, with no changes. Except as required by paragraph (i) of 
this AD: After the existing maintenance or inspection program has 
been revised as required by paragraph (g) of this AD, no alternative

    After the existing maintenance or inspection program has been 
revised as required by paragraph (i) of this AD, no alternative 
actions (e.g., inspections), intervals, and CDCCLs are allowed 
unless they are approved as specified in paragraph (f) of ANAC AD 
2022-02-01.

(l) Additional FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, International Validation 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 responsible Flight 
Standards Office, as appropriate. If sending information directly to 
the Large Aircraft Section, International Validation Branch, send it 
to the attention of the person identified in paragraph (m) of this 
AD. Information may be emailed to: [email protected].
    (i) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the responsible Flight Standards Office.
    (ii) AMOCs approved previously for AD 2019-25-16 are approved as 
AMOCs for the corresponding provisions of paragraph (g) of this AD.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, Large Aircraft 
Section, International Validation Branch, FAA; or ANAC; or ANAC's 
authorized Designee. If approved by the ANAC Designee, the approval 
must include the Designee's authorized signature.
    (3) Required for Compliance (RC): Except as required by 
paragraph (l)(2) of this AD, if any service information referenced 
in ANAC AD 2022-02-01 contains steps in the Accomplishment 
Instructions or figures that are labeled as RC, the instructions in 
RC steps, including subparagraphs under an RC step and any figures 
identified in an RC step, must be done to comply with this AD; any 
steps including substeps under those steps, that are not identified 
as RC are recommended. The instructions in steps, including substeps 
under those steps, not identified as RC may be deviated from using 
accepted methods in accordance with the operator's maintenance or 
inspection program without obtaining approval of an AMOC, provided 
the instructions identified as RC can be done and the airplane can 
be put back in an airworthy condition. Any substitutions or changes 
to instructions identified as RC require approval of an AMOC. If a 
step or substep is labeled ``RC Exempt,'' then the RC requirement is 
removed from that step or substep.
