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.

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.

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

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.

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.

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.
