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 He´licopte`res Guimbal (HG)
Model Cabri G2 helicopters. The NPRM
published in the Federal Register on
August 23, 2021 (86 FR 47038). In the
NPRM, the FAA proposed to require
before further flight, removing from
service certain part-numbered cooling
fan front flanges and engine pulley ball
bearings that have accumulated or
exceeded their life limit. The NPRM
also proposed to require establishing
recurring CMR tasks for certain partnumbered cooling fan front flanges.
Depending on the results of the CMR
tasks, the NPRM proposed to require
corrective action. Additionally, the
NPRM proposed to require painting
certain part-numbered tail booms with
glossy white paint.
The NPRM was prompted by a series
of EASA ADs beginning with EASA AD
2016–0032, dated February 24, 2016
(EASA AD 2016–0032), issued by
EASA, which is the Technical Agent for
the Member States of the European
Union, to correct an unsafe condition
for HG Model Cabri G2 helicopters.
EASA AD 2016–0032 states HG has
revised the airworthiness limitations
and maintenance tasks specified in the
existing maintenance manual. EASA
further advised the revisions include
new and more restrictive applicable life
limits and compliance times for
applicable tasks. Accordingly, EASA
2016–0032 required replacing each
VerDate Sep<11>2014
16:33 Dec 08, 2021
Jkt 256001
affected part before exceeding its life
limit, accomplishing all applicable
maintenance tasks within the defined
intervals as described in revised
maintenance manual and if
discrepancies were found
accomplishing the corrective actions in
accordance with the applicable
maintenance instructions or contacting
HG. EASA AD 2016–0032 also required
revising the existing Aircraft
Maintenance Program (AMP) for your
helicopter by incorporating the actions
specified in the revised maintenance.
After EASA issued EASA AD 2016–
0032, HG again revised the
airworthiness limitations and
maintenance tasks.
Accordingly, EASA superseded EASA
AD 2016–0032 with EASA AD 2019–
0025, dated February 4, 2019 (EASA AD
2019–0025). EASA advises new and
more restrictive life limits have been
established for cooling fan part number
(P/N) G52–00–001, and P/N G52–00–
002, which have been identified as
mandatory for continued airworthiness
in He´licopte`res Guimbal Cabri G2
Maintenance Manual (MM) No. J70–002
Issue 06, dated December 6, 2018,
Section C, Airworthiness Limitations
(the ALS). In addition to the new life
limits, EASA advises of new and more
restrictive inspection intervals
identified in the ALS for cooling fan P/
N G52–00–001 with a certain mounted
cooling fan front flange P/N G52–02–
200, or P/N G52–02–201. EASA further
advises that the ALS revised the tail
structure paint to include certain partnumbered tail booms and an additional
figure. This condition, if not addressed,
could result in parts remaining in
service beyond their fatigue life and
failure of a part, which could result in
loss of control of the helicopter.
Accordingly, EASA AD 2019–0025
retains the requirements of EASA AD
2016–0032 and requires replacing each
affected part before exceeding its life
limit, accomplishing all applicable
maintenance tasks within the defined
intervals as described in the ALS, and
if discrepancies are found
accomplishing the corrective actions in
accordance with the applicable
maintenance instructions or contacting
HG. EASA AD 2019–0025 also requires
revising the tail structure paint scheme
to include certain part-numbered tail
booms and an additional figure. EASA
AD 2019–0025 requires revising the
existing AMP for your helicopter by
incorporating the actions specified in
the ALS.

Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
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 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.
Changes include clarifying the name of
and the specific portions of Guimbal
France He´licopte`res Guimbal Cabri G2
Maintenance Manual and Instructions
for Continued Airworthiness, J70–002—
Issue 06, dated December 6, 2018 (MM
J70–002 Issue 06) that are required to
accomplish this final rule. MM J70–002
Issue 06 also refers to a flashlight as a
torchlight; accordingly, changes have
been made in this final rule to clarify
that where MM J70–002 Issue 06
specifies to use a torchlight, to use a
flashlight instead. This final rule also
removes the requirements of
accomplishing sub section 52–A–10
Cooling Fan Inspection, paragraph d), of
MM J70–002 Issue 06 because it is
unnecessary, this final rule already
provides requirements pertaining to
what to do if there is a crack.
Related Service Information Under 1
CFR Part 51
The FAA reviewed page C–6 of
Section C, Airworthiness Limitations,
and page E–5–53 of Section E,
Maintenance Instructions, of MM J70–
002 Issue 06. This service information
specifies airworthiness life limits,
inspection intervals, and CMR
requirements for parts installed on Cabri
G2 helicopters. MM J70–002 Issue 06
also establishes life limits for certain
part-numbered cooling fan front flanges,
and engine pulley ball bearings and
CMR requirements for certain cooling
fan front flanges.
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 EASA
2019–0025
EASA AD 2019–0025 requires
contacting He´licopte`res Guimbal for
corrective actions when a discrepancy is
E:\FR\FM\09DER1.SGM
09DER1
70002
Federal Register / Vol. 86, No. 234 / Thursday, December 9, 2021 / Rules and Regulations
found, whereas this AD requires
removing the part from service. EASA
AD 2019–0025 requires accomplishing
the actions specified in the ALS,
whereas this AD requires establishing a
life limit for certain part-numbered
cooling fan front flanges and certain
part-numbered engine pulley ball
bearings and removing any part from
service accordingly instead. EASA AD
2019–0025 requires revising the AMP
with the actions specified in the ALS,
whereas this AD does not.
Costs of Compliance
The FAA estimates that this AD
affects 32 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 a cooling fan front flange
takes about 16 work-hours and parts
cost about $4,500 for an estimated cost
of $5,860 per helicopter and $187,520
for the U.S. fleet, per replacement cycle.
Replacing an engine pulley ball
bearing takes about 12 work-hours and
parts cost about $250 for an estimated
cost of $1,270 per helicopter and
$40,640 for the U.S. fleet, per
replacement cycle.
The FAA has no way of determining
the estimated costs to do allowable
repairs based on the results of the CMR
tasks. If required, replacing a cracked
cooling fan front flange takes about 16
work-hours and parts cost about $4,500
for an estimated cost of $5,860.
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 operators.

[Docket No. 211115–0229]
RIN 0694–AH55
Removal of Certain General Approved
Exclusions (GAEs) Under the Section
232 Steel and Aluminum Tariff
Exclusions Process
Bureau of Industry and
Security, U.S. Department of Commerce.
AGENCY:
ACTION:
Interim final rule.
On December 14, 2020, the
Department of Commerce published an
interim final rule (the ‘‘December 14
rule’’) that revised aspects of the process
for requesting exclusions from the
duties and quantitative limitations on
imports of aluminum and steel
discussed in three previous Department
of Commerce (‘‘Commerce’’) interim
final rules implementing the exclusion
process authorized by the President
under Section 232 of the Trade
Expansion Act of 1962, as amended, as
well as a May 26, 2020 notice of inquiry.
The December 14 rule included adding
123 General Approved Exclusions
(GAEs) to the regulations. Subsequently,
based on Commerce’s review of the
public comments received in response
to the December 14 rule and additional
analysis conducted by Commerce on the
Section 232 exclusion request
submissions, Commerce determined
that a subset of the GAEs added in the
December 14 rule no longer meets the
criteria for inclusion as a GAE and
should therefore be removed. Commerce
is removing these GAEs in this interim
final rule to ensure only those GAEs that
meet the stated criteria from the
December 14 rule will continue to be
included as eligible GAEs. This interim
final rule removes thirty of the GAEs
that were added to the regulations in the
December 14 rule, consisting of twentysix GAEs for steel and four GAEs for
aluminum. As a conforming change to a
recent U.S. International Trade
Commission (ITC) decision, this rule
also removes one additional steel GAE.
Lastly, this interim final rule adds a
note to both GAE supplements to
address future changes to the
Harmonized Tariff Schedule of the
United States (HTSUS).

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
H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters. The
NPRM published in the Federal Register on August 23, 2021 (86 FR
47038). In the NPRM, the FAA proposed to require before further flight,
removing from service certain part-numbered cooling fan front flanges
and engine pulley ball bearings that have accumulated or exceeded their
life limit. The NPRM also proposed to require establishing recurring
CMR tasks for certain part-numbered cooling fan front flanges.
Depending on the results of the CMR tasks, the NPRM proposed to require
corrective action. Additionally, the NPRM proposed to require painting
certain part-numbered tail booms with glossy white paint.
The NPRM was prompted by a series of EASA ADs beginning with EASA
AD 2016-0032, dated February 24, 2016 (EASA AD 2016-0032), issued by
EASA, which is the Technical Agent for the Member States of the
European Union, to correct an unsafe condition for HG Model Cabri G2
helicopters. EASA AD 2016-0032 states HG has revised the airworthiness
limitations and maintenance tasks specified in the existing maintenance
manual. EASA further advised the revisions include new and more
restrictive applicable life limits and compliance times for applicable
tasks. Accordingly, EASA 2016-0032 required replacing each affected
part before exceeding its life limit, accomplishing all applicable
maintenance tasks within the defined intervals as described in revised
maintenance manual and if discrepancies were found accomplishing the
corrective actions in accordance with the applicable maintenance
instructions or contacting HG. EASA AD 2016-0032 also required revising
the existing Aircraft Maintenance Program (AMP) for your helicopter by
incorporating the actions specified in the revised maintenance. After
EASA issued EASA AD 2016-0032, HG again revised the airworthiness
limitations and maintenance tasks.
Accordingly, EASA superseded EASA AD 2016-0032 with EASA AD 2019-
0025, dated February 4, 2019 (EASA AD 2019-0025). EASA advises new and
more restrictive life limits have been established for cooling fan part
number (P/N) G52-00-001, and P/N G52-00-002, which have been identified
as mandatory for continued airworthiness in H[eacute]licopt[egrave]res
Guimbal Cabri G2 Maintenance Manual (MM) No. J70-002 Issue 06, dated
December 6, 2018, Section C, Airworthiness Limitations (the ALS). In
addition to the new life limits, EASA advises of new and more
restrictive inspection intervals identified in the ALS for cooling fan
P/N G52-00-001 with a certain mounted cooling fan front flange P/N G52-
02-200, or P/N G52-02-201. EASA further advises that the ALS revised
the tail structure paint to include certain part-numbered tail booms
and an additional figure. This condition, if not addressed, could
result in parts remaining in service beyond their fatigue life and
failure of a part, which could result in loss of control of the
helicopter.
Accordingly, EASA AD 2019-0025 retains the requirements of EASA AD
2016-0032 and requires replacing each affected part before exceeding
its life limit, accomplishing all applicable maintenance tasks within
the defined intervals as described in the ALS, and if discrepancies are
found accomplishing the corrective actions in accordance with the
applicable maintenance instructions or contacting HG. EASA AD 2019-0025
also requires revising the tail structure paint scheme to include
certain part-numbered tail booms and an additional figure. EASA AD
2019-0025 requires revising the existing AMP for your helicopter by
incorporating the actions specified in the ALS.
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
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 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. Changes include clarifying
the name of and the specific portions of Guimbal France
H[eacute]licopt[egrave]res Guimbal Cabri G2 Maintenance Manual and
Instructions for Continued Airworthiness, J70-002--Issue 06, dated
December 6, 2018 (MM J70-002 Issue 06) that are required to accomplish
this final rule. MM J70-002 Issue 06 also refers to a flashlight as a
torchlight; accordingly, changes have been made in this final rule to
clarify that where MM J70-002 Issue 06 specifies to use a torchlight,
to use a flashlight instead. This final rule also removes the
requirements of accomplishing sub section 52-A-10 Cooling Fan
Inspection, paragraph d), of MM J70-002 Issue 06 because it is
unnecessary, this final rule already provides requirements pertaining
to what to do if there is a crack.
Related Service Information Under 1 CFR Part 51
The FAA reviewed page C-6 of Section C, Airworthiness Limitations,
and page E-5-53 of Section E, Maintenance Instructions, of MM J70-002
Issue 06. This service information specifies airworthiness life limits,
inspection intervals, and CMR requirements for parts installed on Cabri
G2 helicopters. MM J70-002 Issue 06 also establishes life limits for
certain part-numbered cooling fan front flanges, and engine pulley ball
bearings and CMR requirements for certain cooling fan front flanges.
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 EASA 2019-0025
EASA AD 2019-0025 requires contacting H[eacute]licopt[egrave]res
Guimbal for corrective actions when a discrepancy is
[[Page 70002]]
found, whereas this AD requires removing the part from service. EASA AD
2019-0025 requires accomplishing the actions specified in the ALS,
whereas this AD requires establishing a life limit for certain part-
numbered cooling fan front flanges and certain part-numbered engine
pulley ball bearings and removing any part from service accordingly
instead. EASA AD 2019-0025 requires revising the AMP with the actions
specified in the ALS, whereas this AD does not.
Costs of Compliance
The FAA estimates that this AD affects 32 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 a cooling fan front flange takes about 16 work-hours and
parts cost about $4,500 for an estimated cost of $5,860 per helicopter
and $187,520 for the U.S. fleet, per replacement cycle.
Replacing an engine pulley ball bearing takes about 12 work-hours
and parts cost about $250 for an estimated cost of $1,270 per
helicopter and $40,640 for the U.S. fleet, per replacement cycle.
The FAA has no way of determining the estimated costs to do
allowable repairs based on the results of the CMR tasks. If required,
replacing a cracked cooling fan front flange takes about 16 work-hours
and parts cost about $4,500 for an estimated cost of $5,860.
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 operators.
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.
