SUPPLEMENTARY INFORMATION:
jbell on DSKJLSW7X2PROD with RULES
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to Bell Textron Canada Limited
Model 206, 206A, 206A–1 (OH–58A),
206B, 206B–1, 206L, 206L–1, 206L–3,
206L–4, 222, 222B, 222U, 230, 407, 427,
429, and 430 helicopters with a comfort
clip installed; or that have been
modified per Supplemental Type
Certificate (STC) SH2073SO
(installation of shoulder harness
restraint system) or STC SH2751SO
(installation of a passenger shoulder
harness restraint system).
The NPRM published in the Federal
Register on July 6, 2021 (86 FR 35410).
In the NPRM, the FAA proposed to
require, within 25 hours time-in-service
(TIS) after the effective date of the
proposed AD, removing from service
each comfort clip and inspecting each
shoulder harness seat belt for a rip and
abrasion. If there is a rip or abrasion, the
NPRM proposed to require removing the
shoulder harness seat belt from service
before further flight. The NPRM also
proposed to prohibit installing a comfort
clip on any helicopter as of the effective
date of the proposed AD.
The NPRM was prompted by
Transport Canada AD CF–2018–16,
dated June 14, 2018 (Transport Canada
VerDate Sep<11>2014
16:25 Sep 07, 2021
Jkt 253001
AD CF–2018–16), issued by Transport
Canada, which is the aviation authority
for Canada, to correct an unsafe
condition for all serial-numbered Bell
Helicopter Textron Canada Limited
(now Bell Textron Canada Limited)
Model 206, 206A, 206A–1, 206B, 206B–
1, 206L, 206L–1, 206L–3, 206L–4, 222,
222B, 222U, 230, 407, 427, 429 and 430
helicopters. Transport Canada advises
that Bell Helicopter Textron Canada
Limited delivered comfort clips with
some helicopters, and that these comfort
clips, which were also sold as spare
parts or accessories, were intended to
improve occupant comfort by reducing
shoulder harness tension. However,
Transport Canada advises the comfort
clip may interfere with the shoulder
harness inertia reel, preventing the
harness from locking and resulting in
injury to the occupant during an
emergency landing. To prevent this
unsafe condition, Transport Canada AD
CF–2018–16 requires, within 25 hours
air time or 10 days, whichever occurs
first, determining if the comfort clips are
installed. If the comfort clips are
installed, Transport Canada AD CF–
2018–16 requires removing them from
service within 100 hours air time or 30
days, whichever occurs first, and
inspecting each shoulder harness seat
belt for damage and replacing any
shoulder harness seat belt that has
damage that exceeds allowable limits
before further flight. Transport Canada
AD CF–2018–16 also prohibits the
installation of any comfort clip on any
helicopter.
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.
Related Service Information
The FAA reviewed the following Bell
Helicopter Alert Service Bulletins
(ASBs), each dated January 11, 2016:
• ASB 222–15–112 for Model 222,
222B, and 222U helicopters with serial
PO 00000

numbers (S/N) 47006 through 47089,
47131 through 47156, and 47501
through 47574 (ASB 222–15–112);
• ASB 230–15–46 for Model 230
helicopters with S/N 23001 through
23038;
• ASB 407–15–111 for Model 407
helicopters with S/N 53000 through
53900, 53911 through 54166, and 54300
through 54599;
• ASB 427–15–39 for Model 427
helicopters with S/N 56001 through
56084, 58001 and 58002 (ASB 427–15–
39);
• ASB 429–15–27 for Model 429
helicopters with S/N 57001 through
57259 (ASB 429–15–27); and
• ASB 430–15–56 for Model 430
helicopters with S/N 49001 through
49129.
The FAA also reviewed the following
Bell Helicopter ASBs, both Revision A
and both dated February 5, 2016:
• ASB 206–15–133 for Model 206A/B
and TH–67 helicopters with S/N 4
through 4690 and 5101 through 5313
(ASB 206–15–133); and
• ASB 206L–15–175 for Model 206L,
206L–1, 206L–3, and 206L–4 helicopters
with S/N 45001 through 45153, 46601
through 46617, 45154 through 45790,
51001 through 51612, and 52001
through 52455 (ASB 206L–15–175).
All of the ASBs specify removing all
variants of comforts clips from all seat
belt assemblies. ASB 222–15–112, ASB
427–15–39, and ASB 429–15–27 also
specify that although the helicopter
models to which these ASBs apply were
not affected by the original design at the
time of certification and delivery of the
helicopter, the affected parts may have
been installed post-delivery to end
owners/operators of those helicopters.
ASB 206–15–133 and ASB 206L–15–
175 also specify that helicopters that
have been modified per STC SH2073SO
(installation of shoulder harness
restraint system) are affected and
therefore included in the ASB
applicability.
ASB 206L–15–175 also specifies that
helicopters that have been modified per
STC SH2751SO (installation of a
passenger shoulder harness restraint
system) are affected and therefore
included in the ASB applicability.
Differences Between This AD and the
Transport Canada AD
This AD requires removing the
comfort clip and inspecting the
shoulder harness seat belt within 25
hours TIS; Transport Canada AD CF–
2018–16 requires inspecting for the
presence of a comfort clip at 25 hours
air time, or 10 days, whichever occurs
first, and then requires removing the
comfort clip, if installed. Transport

Federal Register / Vol. 86, No. 171 / Wednesday, September 8, 2021 / Rules and Regulations
Canada AD CF–2018–16 requires
inspecting the shoulder harness seat belt
for any damage that exceeds allowable
limits within 100 hours air time or 30
days, whichever occurs first, whereas
this AD requires the inspection within
25 hours TIS and removing any
shoulder harness seat belt from service
before further flight if there is any rip or
abrasion.
Transport Canada AD CF–2018–16
applies to all serial-numbered Model
206, 206A, 206A–1, 206B, 206B–1,
206L, 206L–1, 206L–3, 206L–4, 222,
222B, 222U, 230, 407, 427, 429 and 430
helicopters, whereas this AD applies to
Model 206, 206A, 206A–1, 206B, 206B–
1, 206L, 206L–1, 206L–3, 206L–4, 222,
222B, 222U, 230, 407, 427, 429, and 430
helicopters with a comfort clip installed
or helicopters that have been modified
per STC SH2073SO (installation of
shoulder harness restraint system) or
STC SH2751SO (installation of a
passenger shoulder harness restraint
system).
Regulatory Findings
(d) Subject
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.
Joint Aircraft Service Component (JASC)
Code: 2500 Cabin Equipment/Furnishings.
Costs of Compliance
The Amendment
The FAA estimates that this AD
affects 2,347 helicopters of U.S.
Registry. Labor rates are estimated at
$85 per work-hour. Based on these
numbers, the FAA estimates the
following costs to comply with this AD.
Removing each comfort clip will take
about 0.5 work-hour for an estimated
cost of $43 per clip and up to $807,368
for the U.S. fleet.
Replacing a shoulder harness seat
belt, if required, will take about 1 workhour and parts will cost about $250 per
shoulder harness seat belt, for an
estimated cost of $335 per replacement.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
jbell on DSKJLSW7X2PROD with RULES
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 helicopters identified in this
rulemaking action.

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 Bell Textron Canada
Limited Model 206, 206A, 206A-1 (OH-58A), 206B, 206B-1, 206L, 206L-1,
206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, 429, and 430
helicopters with a comfort clip installed; or that have been modified
per Supplemental Type Certificate (STC) SH2073SO (installation of
shoulder harness restraint system) or STC SH2751SO (installation of a
passenger shoulder harness restraint system).
The NPRM published in the Federal Register on July 6, 2021 (86 FR
35410). In the NPRM, the FAA proposed to require, within 25 hours time-
in-service (TIS) after the effective date of the proposed AD, removing
from service each comfort clip and inspecting each shoulder harness
seat belt for a rip and abrasion. If there is a rip or abrasion, the
NPRM proposed to require removing the shoulder harness seat belt from
service before further flight. The NPRM also proposed to prohibit
installing a comfort clip on any helicopter as of the effective date of
the proposed AD.
The NPRM was prompted by Transport Canada AD CF-2018-16, dated June
14, 2018 (Transport Canada AD CF-2018-16), issued by Transport Canada,
which is the aviation authority for Canada, to correct an unsafe
condition for all serial-numbered Bell Helicopter Textron Canada
Limited (now Bell Textron Canada Limited) Model 206, 206A, 206A-1,
206B, 206B-1, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407,
427, 429 and 430 helicopters. Transport Canada advises that Bell
Helicopter Textron Canada Limited delivered comfort clips with some
helicopters, and that these comfort clips, which were also sold as
spare parts or accessories, were intended to improve occupant comfort
by reducing shoulder harness tension. However, Transport Canada advises
the comfort clip may interfere with the shoulder harness inertia reel,
preventing the harness from locking and resulting in injury to the
occupant during an emergency landing. To prevent this unsafe condition,
Transport Canada AD CF-2018-16 requires, within 25 hours air time or 10
days, whichever occurs first, determining if the comfort clips are
installed. If the comfort clips are installed, Transport Canada AD CF-
2018-16 requires removing them from service within 100 hours air time
or 30 days, whichever occurs first, and inspecting each shoulder
harness seat belt for damage and replacing any shoulder harness seat
belt that has damage that exceeds allowable limits before further
flight. Transport Canada AD CF-2018-16 also prohibits the installation
of any comfort clip on any helicopter.
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.
Related Service Information
The FAA reviewed the following Bell Helicopter Alert Service
Bulletins (ASBs), each dated January 11, 2016:
ASB 222-15-112 for Model 222, 222B, and 222U helicopters
with serial numbers (S/N) 47006 through 47089, 47131 through 47156, and
47501 through 47574 (ASB 222-15-112);
ASB 230-15-46 for Model 230 helicopters with S/N 23001
through 23038;
ASB 407-15-111 for Model 407 helicopters with S/N 53000
through 53900, 53911 through 54166, and 54300 through 54599;
ASB 427-15-39 for Model 427 helicopters with S/N 56001
through 56084, 58001 and 58002 (ASB 427-15-39);
ASB 429-15-27 for Model 429 helicopters with S/N 57001
through 57259 (ASB 429-15-27); and
ASB 430-15-56 for Model 430 helicopters with S/N 49001
through 49129.
The FAA also reviewed the following Bell Helicopter ASBs, both
Revision A and both dated February 5, 2016:
ASB 206-15-133 for Model 206A/B and TH-67 helicopters with
S/N 4 through 4690 and 5101 through 5313 (ASB 206-15-133); and
ASB 206L-15-175 for Model 206L, 206L-1, 206L-3, and 206L-4
helicopters with S/N 45001 through 45153, 46601 through 46617, 45154
through 45790, 51001 through 51612, and 52001 through 52455 (ASB 206L-
15-175).
All of the ASBs specify removing all variants of comforts clips
from all seat belt assemblies. ASB 222-15-112, ASB 427-15-39, and ASB
429-15-27 also specify that although the helicopter models to which
these ASBs apply were not affected by the original design at the time
of certification and delivery of the helicopter, the affected parts may
have been installed post-delivery to end owners/operators of those
helicopters.
ASB 206-15-133 and ASB 206L-15-175 also specify that helicopters
that have been modified per STC SH2073SO (installation of shoulder
harness restraint system) are affected and therefore included in the
ASB applicability.
ASB 206L-15-175 also specifies that helicopters that have been
modified per STC SH2751SO (installation of a passenger shoulder harness
restraint system) are affected and therefore included in the ASB
applicability.
Differences Between This AD and the Transport Canada AD
This AD requires removing the comfort clip and inspecting the
shoulder harness seat belt within 25 hours TIS; Transport Canada AD CF-
2018-16 requires inspecting for the presence of a comfort clip at 25
hours air time, or 10 days, whichever occurs first, and then requires
removing the comfort clip, if installed. Transport
[[Page 50234]]
Canada AD CF-2018-16 requires inspecting the shoulder harness seat belt
for any damage that exceeds allowable limits within 100 hours air time
or 30 days, whichever occurs first, whereas this AD requires the
inspection within 25 hours TIS and removing any shoulder harness seat
belt from service before further flight if there is any rip or
abrasion.
Transport Canada AD CF-2018-16 applies to all serial-numbered Model
206, 206A, 206A-1, 206B, 206B-1, 206L, 206L-1, 206L-3, 206L-4, 222,
222B, 222U, 230, 407, 427, 429 and 430 helicopters, whereas this AD
applies to Model 206, 206A, 206A-1, 206B, 206B-1, 206L, 206L-1, 206L-3,
206L-4, 222, 222B, 222U, 230, 407, 427, 429, and 430 helicopters with a
comfort clip installed or helicopters that have been modified per STC
SH2073SO (installation of shoulder harness restraint system) or STC
SH2751SO (installation of a passenger shoulder harness restraint
system).
Costs of Compliance
The FAA estimates that this AD affects 2,347 helicopters of U.S.
Registry. Labor rates are estimated at $85 per work-hour. Based on
these numbers, the FAA estimates the following costs to comply with
this AD.
Removing each comfort clip will take about 0.5 work-hour for an
estimated cost of $43 per clip and up to $807,368 for the U.S. fleet.
Replacing a shoulder harness seat belt, if required, will take
about 1 work-hour and parts will cost about $250 per shoulder harness
seat belt, for an estimated cost of $335 per replacement.
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 helicopters 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.
