The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. VerDate Sep<11>2014 15:39 May 21, 2024 Jkt 262001 Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Shahram Daneshmandi, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 206– 231–3220; email shahram.daneshmandi@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2024–0096, dated May 2, 2024 (EASA AD 2024– 0096) (also referred to as the MCAI), to correct an unsafe condition on all ATR—GIE Avions de Transport Régional Model ATR42–400, –500 and Model ATR72–101, –102, –201, –202, –211, –212, and –212A airplanes. Model ATR42–400 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. The MCAI states one of the two lugs of the TLU lever assembly was reported as having heavy corrosion. Subsequent investigation evidenced that heat treatment of that lug of the TLU lever was not correctly accomplished. This improper heat treatment leads to reduced resistance to intergranular corrosion and could result in heavy corrosion and premature failure of the PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 TLU lever. This condition, if not detected and corrected, could result in the rudder deflection not being limited at high airplane speed, which, if combined with a large rudder pedal input, could ultimately result in loss of control of the airplane. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–1298. Related Service Information Under 1 CFR Part 51 EASA AD 2024–0096 specifies procedures for a visual inspection of affected TLU lever assemblies for corrosion, and, depending on the inspection results, repetitive inspection of the TLU lever assembly or a conductivity test and applicable corrective actions. Corrective actions depend on the conductivity test findings and include contacting the manufacturer for repair instructions and replacing the TLU lever assembly. EASA AD 2024–0096 also requires the conductivity test for all airplanes, requires reporting the inspection results to ATR—GIE Avions de Transport Régional, and prohibits the installation of affected parts. 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. FAA’s Determination 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 is issuing this AD after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Requirements of This AD This AD requires accomplishing the actions specified in EASA AD 2024– 0096 described previously, except for any differences identified as exceptions in the regulatory text of this AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with E:\FR\FM\22MYR1.SGM 22MYR1 44919 Federal Register / Vol. 89, No. 100 / Wednesday, May 22, 2024 / Rules and Regulations requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 2024–0096 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2024–0096 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in EASA AD 2024–0096 does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in EASA AD 2024–0096. Service information required by EASA AD 2024–0096 for compliance will be available at regulations.gov under Docket No. FAA–2024–1298 after this AD is published. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because corrosion on the TLU lever assembly, if not addressed, could result in TLU lever assembly failure and excessive rudder deflection with consequent loss of control of the airplane. In addition, the inspection must be accomplished within 30 calendar days after the effective date of this AD. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 58 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 1.5 work-hours × $85 per hour = $128 ....................................................................................... $0 $128 $7,424 Labor cost Parts cost Cost per product 1 work-hour × $85 per hour = $85 .......................................................................................................................... $5,220 $5,305 ESTIMATED COSTS OF ON-CONDITION ACTIONS khammond on DSKJM1Z7X2PROD with RULES 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. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a currently valid OMB Control Number. The OMB Control Number for this information collection is 2120–0056. Public reporting for this collection of VerDate Sep<11>2014 15:39 May 21, 2024 Jkt 262001 information is estimated to take approximately 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177–1524. 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 PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 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 E:\FR\FM\22MYR1.SGM 22MYR1 44920 Federal Register / Vol. 89, No. 100 / Wednesday, May 22, 2024 / Rules and Regulations 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, and (2) Will not affect intrastate aviation in Alaska.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2024-0096, dated May 2, 2024 (EASA 
AD 2024-0096) (also referred to as the MCAI), to correct an unsafe 
condition on all ATR--GIE Avions de Transport R[eacute]gional Model 
ATR42-400, -500 and Model ATR72-101, -102, -201, -202, -211, -212, and 
-212A airplanes. Model ATR42-400 airplanes are not certificated by the 
FAA and are not included on the U.S. type certificate data sheet; this 
AD therefore does not include those airplanes in the applicability. The 
MCAI states one of the two lugs of the TLU lever assembly was reported 
as having heavy corrosion. Subsequent investigation evidenced that heat 
treatment of that lug of the TLU lever was not correctly accomplished. 
This improper heat treatment leads to reduced resistance to 
intergranular corrosion and could result in heavy corrosion and 
premature failure of the TLU lever. This condition, if not detected and 
corrected, could result in the rudder deflection not being limited at 
high airplane speed, which, if combined with a large rudder pedal 
input, could ultimately result in loss of control of the airplane.
    The FAA is issuing this AD to address the unsafe condition on these 
products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-1298.

Related Service Information Under 1 CFR Part 51

    EASA AD 2024-0096 specifies procedures for a visual inspection of 
affected TLU lever assemblies for corrosion, and, depending on the 
inspection results, repetitive inspection of the TLU lever assembly or 
a conductivity test and applicable corrective actions. Corrective 
actions depend on the conductivity test findings and include contacting 
the manufacturer for repair instructions and replacing the TLU lever 
assembly. EASA AD 2024-0096 also requires the conductivity test for all 
airplanes, requires reporting the inspection results to ATR--GIE Avions 
de Transport R[eacute]gional, and prohibits the installation of 
affected parts.
    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.

FAA's Determination

    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 is issuing this AD after determining that the 
unsafe condition described previously is likely to exist or develop on 
other products of the same type design.

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2024-0096 described previously, except for any differences identified 
as exceptions in the regulatory text of this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with

[[Page 44919]]

requirements for corresponding FAA ADs. The FAA has been coordinating 
this process with manufacturers and CAAs. As a result, EASA AD 2024-
0096 is incorporated by reference in this AD. This AD requires 
compliance with EASA AD 2024-0096 in its entirety through that 
incorporation, except for any differences identified as exceptions in 
the regulatory text of this AD. Using common terms that are the same as 
the heading of a particular section in EASA AD 2024-0096 does not mean 
that operators need comply only with that section. For example, where 
the AD requirement refers to ``all required actions and compliance 
times,'' compliance with this AD requirement is not limited to the 
section titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 
2024-0096. Service information required by EASA AD 2024-0096 for 
compliance will be available at regulations.gov under Docket No. FAA-
2024-1298 after this AD is published.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies forgoing notice and comment prior to adoption of this rule 
because corrosion on the TLU lever assembly, if not addressed, could 
result in TLU lever assembly failure and excessive rudder deflection 
with consequent loss of control of the airplane. In addition, the 
inspection must be accomplished within 30 calendar days after the 
effective date of this AD. Accordingly, notice and opportunity for 
prior public comment are impracticable and contrary to the public 
interest pursuant to 5 U.S.C. 553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forgo notice and 
comment.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 58 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
----------------------------------------------------------------------------------------------------------------
1.5 work-hours x $85 per hour = $128.........................              $0             $128           $7,424
----------------------------------------------------------------------------------------------------------------


                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
1 work-hour x $85 per hour = $85......          $5,220           $5,305
------------------------------------------------------------------------

    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. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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

[[Page 44920]]

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, and
    (2) Will not affect intrastate aviation in Alaska.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by

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 adding the following new airworthiness 
directive:

2024-09-03 ATR--GIE Avions de Transport R[eacute]gional: Amendment 
39-22745; Docket No. FAA-2024-1298; Project Identifier MCAI-2024-
00216-T.

(a) Effective Date

    This airworthiness directive (AD) is effective June 6, 2024.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all ATR--GIE Avions de Transport 
R[eacute]gional Model ATR42-500 and Model ATR72-101, -102, -201, -
202, -211, -212, and -212A airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Unsafe Condition

    This AD was prompted by heavy corrosion on one of the two lugs 
of the travel limiting unit (TLU) lever assembly. The FAA is issuing 
this AD to address corrosion of the TLU lever assembly. The unsafe 
condition, if not detected and corrected, could result in the rudder 
deflection not being limited at high airplane speed which, if 
combined with a large rudder pedal input, could ultimately result in 
loss of control of the airplane.

(f) Compliance

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

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) AD 
2024-0096, dated May 2, 2024 (EASA AD 2024-0096).

AD requires using the effective date of this AD.
    (2) Where paragraph (4) of EASA AD 2024-0096 specifies ``to 
contact ATR for repair instructions and to accomplish those 
instructions accordingly,'' this AD requires replacing that text 
with ``repair of any corrosion before further flight using a method 
approved by the Manager, International Validation Branch, FAA; or 
EASA; or ATR--GIE Avions de Transport R[eacute]gional's EASA Design 
Organization Approval (DOA). If approved by the DOA, the approval 
must include the DOA-authorized signature.''
    (3) The service information referenced in EASA AD 2024-0096 
specifies replacement of the TLU lever ``before further flight'' or 
``within 6 months,'' as applicable depending on the results of the 
inspection and conductivity test. For this AD, the compliance time 
to replace the TLU lever starts from the conductivity test.
    (4) Replace paragraph (8) of EASA AD 2024-0096 with 
``Accomplishment of the applicable actions for affected parts in 
accordance with ATR AOM 2024/04 Issue 1 is acceptable to comply with 
the requirements of paragraphs (1), (2), (3), and (4) of this AD, as 
applicable, for those affected parts only.''
    (5) Paragraph (9) of EASA AD 2024-0096 specifies to report 
inspection results to ATR within a certain compliance time. For this 
AD, report inspection results at the applicable time specified in 
paragraph (h)(5)(i) or (ii) of this AD.
    (i) If the inspection was done on or after the effective date of 
this AD: Submit the report within 10 days after the inspection.
    (ii) If the inspection was done before the effective date of 
this AD: Submit the report within 10 days after the effective date 
of this AD.
    (6) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0096.
