Authority for This Rulemaking
§ 39.13
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.

Helicopter Textron Inc.) Model 204B,
205A, 205A–1, 205B, and 212
helicopters. AD 2021–15–51 required
removing certain main rotor hub strap
pins (pins) from service and prohibited
installing them on any helicopter. Since
the FAA issued AD 2021–15–51, it was
determined that a defective pin could
also be installed on Bell Textron Inc.
Model 210 helicopters. This AD
continues the required actions in AD
2021–15–51 and expands the
applicability to add Model 210
helicopters. The FAA is issuing this AD
to address the unsafe condition on these
products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued Emergency AD 2021–
15–51 on July 6, 2021, and it published
as a Final rule; request for comments on
August 9, 2021 as Amendment 39–
21678 (86 FR 43406) (AD 2021–15–51).
AD 2021–15–51 applied to Bell Textron
Inc., Model 204B, 205A, 205A–1, 205B,
VerDate Sep<11>2014
15:56 Jan 11, 2022
Jkt 256001
and 212 helicopters with a pin part
number (P/N) 204–012–104–005 with a
serial number (S/N) prefix ‘‘FNFS’’
installed. AD 2021–15–51 was
prompted by a fatal accident of a Model
212 helicopter in which a pin P/N 204–
012–104–005 with an S/N prefix
‘‘FNFS’’ sheared off during flight, which
resulted in the main rotor blade and the
main rotor head detaching from the
helicopter. The pin had accumulated
only 20 total hours time-in-service (TIS).
An inspection of a different Model 212
helicopter revealed that another pin
installed, and made by the same
manufacturer and with the same S/N
prefix, was deformed; this pin had
accumulated only 29 total hours TIS.
Because an affected pin could also be
installed on other helicopters, AD 2021–
15–51 also applied to Model 204B,
205A, 205A–1, and 205B helicopters.
Failure of a pin could result in the main
rotor blade detaching from the
helicopter and subsequent loss of
control of the helicopter.
After AD 2021–15–51 was issued, it
was determined that an affected pin
could also be installed on Model 210
helicopters. Therefore, the FAA issued a
notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to supersede
AD 2021–15–51. The NPRM published
in the Federal Register on November 19,
2021 (86 FR 64832) and it proposed to
continue to require all of the
requirements of AD 2021–15–51 and
add Model 210 helicopters to the
applicability.
Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
The FAA reviewed the relevant data
and determined that air safety requires
adoption of the AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these
products. Except for minor editorial
changes, this AD is adopted as proposed
in the NPRM.
Related Service Information
The FAA reviewed Bell Alert Service
Bulletins (ASBs), each Revision A and
dated July 22, 2021:
• ASB 204B–21–74 for Model 204B
helicopters, S/Ns 2001 through 2070
and 2196 through 2199;
• ASB 205–21–117 for Model 205A
and 205A–1 helicopters, S/Ns 30001
through 30065, 30067 through 30165,
30167 through 30187, 30189 through
30296, and 30298 through 30332;

Frm 00013
Fmt 4700

• ASB 205B–21–71 for Model 205B
helicopters, S/Ns 30066, 30166, 30188
and 30297;
• ASB 210–21–14 for all Model 210
helicopters, and
• ASB 212–21–165 for Model 212
helicopters, S/Ns 30501 through 30999,
31101 through 31311, 32101 through
32142, and 35001 through 35103.
The ASBs specify removing all P/N
204–012–104–005 pins with an S/N
prefix ‘‘FNFS’’ before further flight. The
ASBs also specify that, although the
investigation is still in progress,
removing these pins from service is
required. The ASBs state that these pins
may not have been manufactured in
accordance with the engineering design
requirements and may therefore shear as
a result of this nonconformance.
Interim Action
The FAA considers this AD to be an
interim action. If final action is later
identified, the FAA might consider
further rulemaking.
Costs of Compliance
The FAA estimates that this AD
affects 155 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.
Replacing up to four pins takes about
20 work-hours and parts cost about
$1,756 for four pins for an estimated
cost of up to $3,456 per helicopter, and
up to $535,680 for the U.S. fleet.
The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some of the
costs of this AD may be covered under
warranty, thereby reducing the cost
impact on affected individuals.
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

Federal Register / Vol. 87, No. 8 / Wednesday, January 12, 2022 / Rules and Regulations
develop on products identified in this
rulemaking action.
Regulatory Findings
The FAA has determined that 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.

helicopters with a pin part number (P/N) 204-012-104-005 with a serial
number (S/N) prefix ``FNFS'' installed. AD 2021-15-51 was prompted by a
fatal accident of a Model 212 helicopter in which a pin P/N 204-012-
104-005 with an S/N prefix ``FNFS'' sheared off during flight, which
resulted in the main rotor blade and the main rotor head detaching from
the helicopter. The pin had accumulated only 20 total hours time-in-
service (TIS). An inspection of a different Model 212 helicopter
revealed that another pin installed, and made by the same manufacturer
and with the same S/N prefix, was deformed; this pin had accumulated
only 29 total hours TIS. Because an affected pin could also be
installed on other helicopters, AD 2021-15-51 also applied to Model
204B, 205A, 205A-1, and 205B helicopters. Failure of a pin could result
in the main rotor blade detaching from the helicopter and subsequent
loss of control of the helicopter.
After AD 2021-15-51 was issued, it was determined that an affected
pin could also be installed on Model 210 helicopters. Therefore, the
FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part
39 to supersede AD 2021-15-51. The NPRM published in the Federal
Register on November 19, 2021 (86 FR 64832) and it proposed to continue
to require all of the requirements of AD 2021-15-51 and add Model 210
helicopters to the applicability.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
The FAA reviewed the relevant data and determined that air safety
requires adoption of the AD as proposed. Accordingly, the FAA is
issuing this AD to address the unsafe condition on these products.
Except for minor editorial changes, this AD is adopted as proposed in
the NPRM.
Related Service Information
The FAA reviewed Bell Alert Service Bulletins (ASBs), each Revision
A and dated July 22, 2021:
ASB 204B-21-74 for Model 204B helicopters, S/Ns 2001
through 2070 and 2196 through 2199;
ASB 205-21-117 for Model 205A and 205A-1 helicopters, S/Ns
30001 through 30065, 30067 through 30165, 30167 through 30187, 30189
through 30296, and 30298 through 30332;
ASB 205B-21-71 for Model 205B helicopters, S/Ns 30066,
30166, 30188 and 30297;
ASB 210-21-14 for all Model 210 helicopters, and
ASB 212-21-165 for Model 212 helicopters, S/Ns 30501
through 30999, 31101 through 31311, 32101 through 32142, and 35001
through 35103.
The ASBs specify removing all P/N 204-012-104-005 pins with an S/N
prefix ``FNFS'' before further flight. The ASBs also specify that,
although the investigation is still in progress, removing these pins
from service is required. The ASBs state that these pins may not have
been manufactured in accordance with the engineering design
requirements and may therefore shear as a result of this
nonconformance.
Interim Action
The FAA considers this AD to be an interim action. If final action
is later identified, the FAA might consider further rulemaking.
Costs of Compliance
The FAA estimates that this AD affects 155 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.
Replacing up to four pins takes about 20 work-hours and parts cost
about $1,756 for four pins for an estimated cost of up to $3,456 per
helicopter, and up to $535,680 for the U.S. fleet.
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected individuals.
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
[[Page 1670]]
develop on products identified in this rulemaking action.
Regulatory Findings
The FAA has determined that 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.
