SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0202, dated August 19, 2019 (EASA AD 2019– 0202), to correct an unsafe condition for PZL Swidnik S.A. Model PZL W–3A and PZL W–3AS helicopters all manufacturer serial numbers. Model PZL W–3AS helicopters 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 helicopters in the applicability. EASA advises that an occurrence was reported where displaced teeth were detected on the moveable assemblies of an MR blade droop stop part number (P/ N) 37.21.800.00.00). This condition, if not addressed, could result in erroneous operation of MR blade droop stop teeth during engine start-up or shut-down, or dynamic drop-down of an MR blade, resulting in contact of the affected MR blade with the tail boom, and possibly resulting in injury of occupants or persons on the ground. Accordingly, EASA AD 2019–0202 requires removal of each affected part from any helicopter on which it is installed and prohibits installation of any affected MR blade droop stop or any moveable assembly of an affected MR blade droop stop on any helicopter. lotter on DSK11XQN23PROD with RULES1 FAA’s Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design. Related Service Information Under 1 CFR Part 51 ´ RNIA The FAA reviewed WYTWO SPRZE˛TU KOMUNIKACYJNEGO ‘‘PZLS´widnik’’ Spo´5ka Akcyjna Mandatory Bulletin No. BO–37–18–302, Revision 1, dated July 11, 2019. This service information specifies procedures for removing the moveable assemblies of the MR blade droop stops. The service VerDate Sep<11>2014 16:20 Sep 24, 2021 Jkt 253001 information specifies that the MR blade droop stop consists of four retaining washers that are installed on the MR hub flapping hinges and four moveable MR blade droop stop assemblies installed on the retaining washers. 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. Other Related Service Information The FAA also reviewed ´ RNIA SPRZE˛TU WYTWO KOMUNIKACYJNEGO ‘‘PZL-S´widnik’’ Spo´5ka Akcyjna Mandatory Bulletin No. BO–37–18–302, dated June 19, 2019. This service information also specifies procedures for removing the moveable assemblies of the MR blade droop stops but does not include the detailed effectivity and scope of compliance that ´ RNIA SPRZE˛TU is included in WYTWO KOMUNIKACYJNEGO ‘‘PZL-S´widnik’’ Spo´5ka Akcyjna Mandatory Bulletin No. BO–37–18–302, Revision 1, dated July 11, 2019. AD Requirements This AD requires accomplishing the actions specified in the service information already described. 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. There are no helicopters with this type certificate on the U.S. Registry. Accordingly, notice and opportunity for prior public comment are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the foregoing reason, 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. Comments Invited The FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2021–0723; PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 53201 Project Identifier MCAI–2020–00268–R’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. 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 https:// www.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 Andrea Jimenez, Aerospace Engineer, COS Program Management Section, Operational Safety Branch, Compliance & Airworthiness Division, FAA, 1600 Stewart Ave., Suite 410, Westbury, NY 11590; telephone (516) 228–7330; email andrea.jimenez@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. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (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 prior notice and comment, RFA analysis is not required. Costs of Compliance There are no costs of compliance with this AD because there are no helicopters E:\FR\FM\27SER1.SGM 27SER1 53202 Federal Register / Vol. 86, No. 184 / Monday, September 27, 2021 / Rules and Regulations 2021–18–15 PZL Swidnik S.A.: Amendment 39–21716; Docket No. FAA–2021–0723; Project Identifier MCAI–2020–00268–R. with this type certificate on the U.S. Registry. 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, 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.

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 Bell Textron Canada Limited (Bell) Model 429 helicopters. The NPRM published in the Federal Register on June 28, 2021 (86 FR 33918). In the NPRM, the FAA proposed to require repetitive torque checks of the tail rotor gearbox attachment hardware, and corrective action if necessary. The NPRM was prompted by Canadian AD CF–2018–35, dated December 19, 2018 (Canadian AD CF–2018–35), issued by Transport Canada, which is the aviation authority for Canada, to correct an unsafe condition for Bell Textron Canada Limited Model 429 helicopters. Transport Canada advises that there have been reports of tail rotor gearbox assemblies found loose on the gearbox support. Transport Canada issued Emergency Canadian Airworthiness Directive CF–2018–18, dated July 11, 2018, which corresponds to FAA AD 2018–16–51, Amendment 39–19421 (83 FR 53171, October 22, 2018), to address the immediate safety concern. An ongoing investigation determined that this condition-loose tail rotor gearbox assemblies-could return even after the corrective actions by the previous AD have been completed. This condition, if not addressed, could result in structural PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 53203 damage and possible loss of control of the helicopter. Accordingly, Canadian AD CF–2018– 35 requires repetitive torque checks of the tail rotor gearbox attachment hardware and corrective actions if necessary. The corrective action is doing additional repetitive torque checks at intervals of 10 to 25 hours air time until the torque stabilizes on all the nuts. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. Conclusion These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with Canada, Transport Canada, its technical representative, has notified the FAA of the unsafe condition described in its AD. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. Related Service Information Under 1 CFR Part 51 The FAA reviewed Bell Alert Service Bulletin 429–18–41, dated July 24, 2018. This service information specifies procedures for repetitive torque checks of the tail rotor gearbox attachment hardware. 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. Differences Between This AD and the Transport Canada AD Where Canadian AD CF–2018–35 refers to ‘‘200-hour’’ inspections and ‘‘10 to 25 hours air time’’ for the torque checks, for this AD use ‘‘time-inservice’’ instead. Costs of Compliance The FAA estimates that this AD affects 98 helicopters of U.S. Registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\27SER1.SGM 27SER1

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain PZL Swidnik S.A. Model PZL W-3A helicopters. This AD was 
prompted by a report that displaced teeth were detected on the moveable 
assemblies of a main rotor (MR) blade droop stop. This AD requires

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0202, dated August 19, 2019 
(EASA AD 2019-0202), to correct an unsafe condition for PZL Swidnik 
S.A. Model PZL W-3A and PZL W-3AS helicopters all manufacturer serial 
numbers. Model PZL W-3AS helicopters 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 helicopters in the applicability.
    EASA advises that an occurrence was reported where displaced teeth 
were detected on the moveable assemblies of an MR blade droop stop part 
number (P/N) 37.21.800.00.00). This condition, if not addressed, could 
result in erroneous operation of MR blade droop stop teeth during 
engine start-up or shut-down, or dynamic drop-down of an MR blade, 
resulting in contact of the affected MR blade with the tail boom, and 
possibly resulting in injury of occupants or persons on the ground.
    Accordingly, EASA AD 2019-0202 requires removal of each affected 
part from any helicopter on which it is installed and prohibits 
installation of any affected MR blade droop stop or any moveable 
assembly of an affected MR blade droop stop on any helicopter.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA about the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all known relevant information and determining that the 
unsafe condition described previously is likely to exist or develop on 
other helicopters of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed WYTW[Oacute]RNIA SPRZ[Eogon]TU KOMUNIKACYJNEGO 
``PZL-[Sacute]widnik'' Sp[oacute][lstrok]ka Akcyjna Mandatory Bulletin 
No. BO-37-18-302, Revision 1, dated July 11, 2019. This service 
information specifies procedures for removing the moveable assemblies 
of the MR blade droop stops. The service information specifies that the 
MR blade droop stop consists of four retaining washers that are 
installed on the MR hub flapping hinges and four moveable MR blade 
droop stop assemblies installed on the retaining washers.
    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.

Other Related Service Information

    The FAA also reviewed WYTW[Oacute]RNIA SPRZ[Eogon]TU 
KOMUNIKACYJNEGO ``PZL-[Sacute]widnik'' Sp[oacute][lstrok]ka Akcyjna 
Mandatory Bulletin No. BO-37-18-302, dated June 19, 2019. This service 
information also specifies procedures for removing the moveable 
assemblies of the MR blade droop stops but does not include the 
detailed effectivity and scope of compliance that is included in 
WYTW[Oacute]RNIA SPRZ[Eogon]TU KOMUNIKACYJNEGO ``PZL-[Sacute]widnik''

Revision 1, dated July 11, 2019.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information already described.

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.
    There are no helicopters with this type certificate on the U.S. 
Registry. Accordingly, notice and opportunity for prior public comment 
are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for 
the foregoing reason, 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.

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2021-0723; Project Identifier MCAI-
2020-00268-R'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    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 
https://www.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 Andrea 
Jimenez, Aerospace Engineer, COS Program Management Section, 
Operational Safety Branch, Compliance & Airworthiness Division, FAA, 
1600 Stewart Ave., Suite 410, Westbury, NY 11590; telephone (516) 228-
7330; email [email protected]. Any commentary that the FAA 
receives which is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (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 prior notice and 
comment, RFA analysis is not required.

Costs of Compliance

    There are no costs of compliance with this AD because there are no 
helicopters

[[Page 53202]]

with this type certificate on the U.S. Registry.

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, 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.
