2. The FAA amends § 39.13 by adding
the following new airworthiness
directive:
■
Airbus Helicopters: Docket No. FAA–2022–
0097; Project Identifier MCAI–2021–
01115–R.
(a) Comments Due Date
The FAA must receive comments on this
airworthiness directive (AD) by March 28,
2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Airbus Helicopters
Model EC 155B and EC155B1 helicopters,
certificated in any category.

(e) Unsafe Condition
This AD was prompted by a report of a
discrepancy in the Rotorcraft Flight Manual
(RFM) where the rotorcraft stay-up flying
capabilities for Category B operation were
provided through performance data only, not
as airworthiness limitations that are
dependent upon the number of passengers on
board. The FAA is issuing this AD to address
this discrepancy in the RFM, which could
lead to an incorrect determination of the stayup flying capabilities, possibly resulting in
reduced control of the helicopter.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.

Background
The FAA issued AD 2020–22–01,
Amendment 39–21297 (85 FR 69126,
November 2, 2020), (AD 2020–22–01),
for all Airbus Helicopters Model
AS332C, AS332C1, AS332L, and
AS332L1 helicopters. AD 2020–22–01
requires, within certain compliance
times specified in the manufacturers
service information, inspecting the
attachment fittings and attachment
screws of the main gearbox (MGB)
suspension bars and their frame bores
for discrepancies and corrective actions
in accordance with the actions specified
in the service information. AD 2020–22–
01 also requires sending certain
information to the manufacturer. AD
2020–22–01 resulted from reports of
corrosion on attachment screws and
fittings fastening the MGB suspension
bars to the fuselage. The FAA issued AD
2020–22–01 to address corrosion on
attachment fittings and attachment
screws for the MGB suspension bars.
AD 2020–22–01 was prompted by
EASA AD 2019–0295, dated December
5, 2019 (EASA AD 2019–0295), issued
by EASA, which is the Technical Agent
for the Member States of the European
Union, to correct an unsafe condition
for all Airbus Helicopters Model AS 332
C, AS 332 C1, AS 332 L, and AS 332 L1
helicopters, all manufacturer serial
numbers. EASA advised that there were
reports of corrosion on attachment
screws and fittings fastening the rear
MGB suspension bars, right and left
hand sides, to the fuselage, and the
attachment screws and fitting fastening
the front MGB suspension bar to the
fuselage. EASA advised that subsequent
investigation determined that during
maintenance visits of an identified
batch of helicopters between September
2012 and April 2019, application of
compound sealant on MGB suspension
bar attachment screws may not have
been accomplished using the approved
maintenance data. This condition, if not
addressed, could lead to structural
failure of the MGB attachment screws,
PO 00000
Frm 00014
Fmt 4702
Sfmt 4702
7771
resulting in detachment of MGB
suspension bars from the fuselage and
subsequent loss of control of the
helicopter.
Accordingly, EASA AD 2019–0295
required a one-time inspection of the
affected parts, and depending on
findings, accomplishment of applicable
corrective actions. The compliance
times varied depending on helicopter
configuration.
Actions Since AD 2020–22–01 Was
Issued
Since the FAA issued AD 2020–22–
01, EASA issued EASA AD 2021–0222,
dated October 6, 2021 (EASA AD 2021–
0222), which supersedes EASA AD
2019–0295. EASA advises a significant
number of reports were received about
corrosion being detected on the affected
parts. EASA also advises Airbus
Helicopters issued updated service
information, which includes
instructions for repetitive inspections.
Accordingly, EASA AD 2021–0222
retains the requirements of EASA AD
2019–0295 and adds repetitive
inspections and updated service
information. Additionally, Airbus
Helicopters advised of a typo in the
applicable service information in the
reference to G.2 of one of the work
cards. Accordingly, the FAA has
identified this typo in the exceptions in
the regulatory text of this proposed AD.
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
proposing this AD after evaluating all
known relevant information and
determining that the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Airbus Helicopters
Alert Service Bulletin (ASB) No.
AS332–53.02.05, Revision 2, and ASB
No. AS332–53.02.07, Revision 1, both
dated August 19, 2021, which specify
procedures for inspecting the
attachment fittings and attachment
screws of the MGB suspension bars and
their frame bores for discrepancies and
corrective actions. This inspection
includes inspecting the attachment
fittings for corrosion and inspecting the
attachment screws for corrosion and
evidence of sealing compound. The
corrective actions include replacing or
E:\FR\FM\10FEP1.SGM
10FEP1
7772
Federal Register / Vol. 87, No. 28 / Thursday, February 10, 2022 / Proposed Rules
repairing corroded parts and replacing
screws that have sealing compound on
them. These documents are distinct
since they apply to different helicopter
models in different configurations.
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 Airbus
Helicopters ASB No. AS332–53.02.05,
Revision 0, dated April 18, 2019; Airbus
Helicopters ASB No. AS332–53.02.05,
Revision 1, dated March 2, 2020; and
Airbus Helicopters ASB No. AS332–
53.02.07, Revision 0, dated October 21,
2019, which also specify procedures for
inspecting the attachment fittings and
attachment screws of the MGB
suspension bars and their frame bores
for discrepancies and corrective actions.
Proposed AD Requirements
This proposed AD would retain all
requirements of AD 2020–22–01. This
proposed AD would add repetitive
inspections and update the applicable
service information. This proposed AD
would require accomplishing the
actions specified in the service
information described previously.
jspears on DSK121TN23PROD with PROPOSALS1
Costs of Compliance
The FAA estimates that this AD
would affect 10 helicopters of U.S.
Registry. Labor rates are estimated at
$85 per work-hour. Based on these
numbers, the FAA estimates that
operators may incur the following costs
in order to comply with this proposed
AD.
Inspecting each attachment screw and
fitting of the rear MGB suspension bars;
each attachment screw and fitting of the
front MGB suspension bar; and the
frame bores would take about 16 workhours, for an estimated cost of $1,360
per helicopter and $13,600 for the U.S.
fleet per inspection cycle.
The FAA estimates the following
costs to do any necessary on-condition
corrective actions that would be
required based on the results of the
inspection. The agency has no way of
determining the number of helicopters
that might need these on-condition
replacements:
If required, replacing an affected
screw, nut, split pin, concave washer,
convex washer, or peel shim would take
a minimal amount of time with a
minimal cost.
If required, replacing an affected MGB
attachment fitting would take about 8
work-hours and parts would cost about
VerDate Sep<11>2014
16:44 Feb 09, 2022
Jkt 256001
$7,000 for an estimated cost of $7,680
per replacement.
If required, reporting any
discrepancies to Airbus Helicopters
would take about 1 work-hour for an
estimated cost of $85 per helicopter.
Paperwork Reduction Act
A federal agency may not conduct or
sponsor, and a person is not required to
respond to, nor shall a person be subject
to a penalty for failure to comply with
a collection of information subject to the
requirements of the Paperwork
Reduction Act unless that collection of
information displays a currently valid
OMB Control Number. The OMB
Control Number for this information
collection is 2120–0056. Public
reporting for this collection of
information is estimated to be
approximately 1 hour per response,
including the time for reviewing
instructions, searching existing data
sources, gathering and maintaining the
data needed, and completing and
reviewing the collection of information.
All responses to this collection of
information are mandatory. Send
comments regarding this burden
estimate or any other aspect of this
collection of information, including
suggestions for reducing this burden to:

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
The FAA has determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would not
have a substantial direct effect on the
PO 00000
Frm 00015
Fmt 4702
Sfmt 4702
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 the proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2020-22-01 which applies to all Airbus Helicopters Model AS332C,
AS332C1, AS332L, and AS332L1 helicopters. AD 2020-22-01 requires
inspecting the affected parts and associated frame bores for
discrepancies, applicable corrective actions, and reporting certain
information if necessary. Since the FAA issued AD 2020-22-01, a
significant number of reports were received of finding corrosion on the
affected parts. This proposed AD would retain the requirements of AD
2020-22-01, add recurring inspections, and update the applicable
service information. The FAA is proposing this AD to address the unsafe
condition on these products.
DATES: The FAA must receive comments on this proposed AD by March 28,
2022.

Background
The FAA issued AD 2020-22-01, Amendment 39-21297 (85 FR 69126,
November 2, 2020), (AD 2020-22-01), for all Airbus Helicopters Model
AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2020-22-01
requires, within certain compliance times specified in the
manufacturers service information, inspecting the attachment fittings
and attachment screws of the main gearbox (MGB) suspension bars and
their frame bores for discrepancies and corrective actions in
accordance with the actions specified in the service information. AD
2020-22-01 also requires sending certain information to the
manufacturer. AD 2020-22-01 resulted from reports of corrosion on
attachment screws and fittings fastening the MGB suspension bars to the
fuselage. The FAA issued AD 2020-22-01 to address corrosion on
attachment fittings and attachment screws for the MGB suspension bars.
AD 2020-22-01 was prompted by EASA AD 2019-0295, dated December 5,
2019 (EASA AD 2019-0295), issued by EASA, which is the Technical Agent
for the Member States of the European Union, to correct an unsafe
condition for all Airbus Helicopters Model AS 332 C, AS 332 C1, AS 332
L, and AS 332 L1 helicopters, all manufacturer serial numbers. EASA
advised that there were reports of corrosion on attachment screws and
fittings fastening the rear MGB suspension bars, right and left hand
sides, to the fuselage, and the attachment screws and fitting fastening
the front MGB suspension bar to the fuselage. EASA advised that
subsequent investigation determined that during maintenance visits of
an identified batch of helicopters between September 2012 and April
2019, application of compound sealant on MGB suspension bar attachment
screws may not have been accomplished using the approved maintenance
data. This condition, if not addressed, could lead to structural
failure of the MGB attachment screws, resulting in detachment of MGB
suspension bars from the fuselage and subsequent loss of control of the
helicopter.
Accordingly, EASA AD 2019-0295 required a one-time inspection of
the affected parts, and depending on findings, accomplishment of
applicable corrective actions. The compliance times varied depending on
helicopter configuration.
Actions Since AD 2020-22-01 Was Issued
Since the FAA issued AD 2020-22-01, EASA issued EASA AD 2021-0222,
dated October 6, 2021 (EASA AD 2021-0222), which supersedes EASA AD
2019-0295. EASA advises a significant number of reports were received
about corrosion being detected on the affected parts. EASA also advises
Airbus Helicopters issued updated service information, which includes
instructions for repetitive inspections. Accordingly, EASA AD 2021-0222
retains the requirements of EASA AD 2019-0295 and adds repetitive
inspections and updated service information. Additionally, Airbus
Helicopters advised of a typo in the applicable service information in
the reference to G.2 of one of the work cards. Accordingly, the FAA has
identified this typo in the exceptions in the regulatory text of this
proposed AD.
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 proposing this AD
after evaluating all known relevant information and determining that
the unsafe condition described previously is likely to exist or develop
on other products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Airbus Helicopters Alert Service Bulletin (ASB)
No. AS332-53.02.05, Revision 2, and ASB No. AS332-53.02.07, Revision 1,
both dated August 19, 2021, which specify procedures for inspecting the
attachment fittings and attachment screws of the MGB suspension bars
and their frame bores for discrepancies and corrective actions. This
inspection includes inspecting the attachment fittings for corrosion
and inspecting the attachment screws for corrosion and evidence of
sealing compound. The corrective actions include replacing or
[[Page 7772]]
repairing corroded parts and replacing screws that have sealing
compound on them. These documents are distinct since they apply to
different helicopter models in different configurations.
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 Airbus Helicopters ASB No. AS332-53.02.05,
Revision 0, dated April 18, 2019; Airbus Helicopters ASB No. AS332-
53.02.05, Revision 1, dated March 2, 2020; and Airbus Helicopters ASB
No. AS332-53.02.07, Revision 0, dated October 21, 2019, which also
specify procedures for inspecting the attachment fittings and
attachment screws of the MGB suspension bars and their frame bores for
discrepancies and corrective actions.
Proposed AD Requirements
This proposed AD would retain all requirements of AD 2020-22-01.
This proposed AD would add repetitive inspections and update the
applicable service information. This proposed AD would require
accomplishing the actions specified in the service information
described previously.
Costs of Compliance
The FAA estimates that this AD would affect 10 helicopters of U.S.
Registry. Labor rates are estimated at $85 per work-hour. Based on
these numbers, the FAA estimates that operators may incur the following
costs in order to comply with this proposed AD.
Inspecting each attachment screw and fitting of the rear MGB
suspension bars; each attachment screw and fitting of the front MGB
suspension bar; and the frame bores would take about 16 work-hours, for
an estimated cost of $1,360 per helicopter and $13,600 for the U.S.
fleet per inspection cycle.
The FAA estimates the following costs to do any necessary on-
condition corrective actions that would be required based on the
results of the inspection. The agency has no way of determining the
number of helicopters that might need these on-condition replacements:
If required, replacing an affected screw, nut, split pin, concave
washer, convex washer, or peel shim would take a minimal amount of time
with a minimal cost.
If required, replacing an affected MGB attachment fitting would
take about 8 work-hours and parts would cost about $7,000 for an
estimated cost of $7,680 per replacement.
If required, reporting any discrepancies to Airbus Helicopters
would take about 1 work-hour for an estimated cost of $85 per
helicopter.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a currently valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to be
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information. All responses to this collection of
information are mandatory. Send comments regarding this burden estimate
or any other aspect of this collection of information, including
suggestions for reducing this burden to: Information Collection
Clearance Officer, Federal Aviation Administration, 10101 Hillwood
Parkway, Fort Worth, TX 76177-1524.
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
The FAA has determined that this proposed AD would not have
federalism implications under Executive Order 13132. This proposed AD
would 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 the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
