Federal Register / Vol. 87, No. 195 / Tuesday, October 11, 2022 / Rules and Regulations
khammond on DSKJM1Z7X2PROD with RULES
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2021–10–10,
Amendment 39–21543 (86 FR 27271,
May 20, 2021) (AD 2021–10–10). AD
2021–10–10 applied to all Airbus
Helicopters Model SA330J helicopters.
AD 2021–10–10 required repetitively
inspecting the MGB particle detector
and the MGB bottom housing (oil sump)
for metal particles, analyzing any metal
particles that are found, and
replacement of the MGB if necessary.
AD 2021–10–10 was prompted by EASA
AD 2018–0272, dated December 13,
2018 (EASA AD 2018–0272), 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 SA 330
J helicopters. The FAA issued AD 2021–
10–10 to address failure of an MGB
second stage planet gear, which could
result in failure of the MGB and
subsequent loss of control of the
helicopter.
The NPRM published in the Federal
Register on July 21, 2022 (87 FR 43453).
The NPRM was prompted by EASA AD
2021–0239, dated November 5, 2021
(EASA AD 2021–0239). EASA AD 2021–
0239 supersedes EASA AD 2018–0272
and continues to require repetitively
inspecting the MGB particle detector
and the MGB bottom housing (oil sump)
for metal particles, and analyzing any
metal particles that are found. EASA AD
2021–0239 also requires installing an
MGB equipped with a new second-stage
planet gear assembly part number (P/N)
330A32–9861–02 (mod 0751091) or
modifying an affected MGB by having
the second stage planet gear assembly
replaced by an Airbus Helicopters
qualified technician; and extends the
compliance time for the repetitive MGB
bottom housing (oil sump) inspections
and establishes a life limit for post-mod
0751091 helicopters.
You may examine EASA AD 2021–
0239 in the AD docket at regulations.gov
under Docket No. FAA–2022–0888.
In the NPRM, the FAA proposed to
require accomplishing the actions
specified in EASA AD 2021–0239,
described previously, as incorporated by
reference, except for any differences
identified as exceptions in the
regulatory text of this AD and except as
discussed under ‘‘Differences Between
this AD and the EASA AD.’’

Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
These products have been approved
by the aviation authority of another
country and are approved for operation
in the United States. Pursuant to the
FAA’s bilateral agreement with this
State of Design Authority, it has notified
the FAA of the unsafe condition
described in its AD referenced above.
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
products. Except for minor editorial
changes, this AD is adopted as proposed
in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed EASA AD 2021–
0239, which supersedes EASA AD
2018–0272 and continues to require
repetitively inspecting the MGB particle
detector and the MGB bottom housing
(oil sump) for metal particles, and
analyzing any metal particles that are
found. EASA AD 2021–0239 also
requires installing an MGB equipped
with a new second-stage planet gear
assembly P/N 330A32–9861–02 (mod
0751091) or modifying an affected MGB
by having the second stage planet gear
assembly replaced by an Airbus
Helicopters qualified technician; and
extends the compliance time for the
repetitive MGB bottom housing (oil
sump) inspections and establishes a life
limit for post-mod 0751091 helicopters.
This material is reasonably available
because the interested parties have
access to it through their normal course
of business or by the means identified
in ADDRESSES.
Other Related Service Information
The FAA reviewed Airbus Helicopters
Alert Service Bulletin (ASB) No.
SA330–05.103, Revision 3, dated
October 4, 2021. This service
information specifies procedures for
checking (inspecting) the MGB particle
detector and the bottom housing (oil
sump) to ensure that there are no
particles, and for particle analysis.
The FAA also reviewed Airbus
Helicopters ASB No. SA330–65.139,
Revision 0, dated October 4, 2021 (ASB
SA330–65.139). This service
information specifies procedures for
installing an MGB equipped with a new

Fmt 4700
Sfmt 4700
second-stage planet gear assembly P/N
330A32–9861–02 (mod 0751091) and
the alternate action of having the second
stage planet gear assembly replaced by
an Airbus Helicopters qualified
technician. The new second stage planet
gear assembly has improved stress and
fatigue characteristics. ASB SA330–
65.139 also establishes an airworthiness
limitation of 2,750 flight hours for all
post-mod 0751091 planet gear
assemblies.
Differences Between This AD and the
EASA AD
EASA AD 2021–0239 requires certain
actions be done after the last flight of
the day or ‘‘ALF,’’ whereas this AD
requires doing those actions before the
first flight of the day. EASA AD 2021–
0239 requires contacting the
manufacturer if unsure about the
characterization of the particles
collected, whereas this AD does not. If
there are any 16NCD13 particles, EASA
AD 2021–0239 requires contacting the
manufacturer and sending a 1-liter
sample of oil to the manufacturer,
whereas this AD does not. EASA AD
2021–0239 requires returning certain
parts to the manufacturer, whereas this
AD does not. EASA AD 2021–0239
allows the option of modifying an
affected MGB by having the second
stage planet gear assembly replaced by
an Airbus Helicopters qualified
technician, whereas this AD allows that
modification with certain approvals
instead. EASA AD 2021–0239 allows
different methods to accomplish the oil
sump inspection, whereas this AD
requires a certain method. EASA AD
2021–0239 requires discarding certain
parts, whereas this AD requires
removing those parts from service
instead.
Costs of Compliance
The FAA estimates that this AD
affects 15 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.
Inspecting the MGB particle detector
takes about 0.25 work-hour for an
estimated cost of $21 per helicopter and
$315 for the U.S. fleet, per inspection
cycle. Inspecting the MGB bottom
housing (oil sump) takes up to about 4
work-hours for an estimated cost of
$340 per helicopter and $5,100 for the
U.S. fleet, per inspection cycle.
Replacing a second stage planet gear
assembly takes about 100 work-hours
and parts cost about $121,140 for an
estimated cost of $129,640 per
helicopter and $1,944,600 for the U.S.
fleet, per replacement cycle.
E:\FR\FM\11OCR1.SGM
11OCR1
Federal Register / Vol. 87, No. 195 / Tuesday, October 11, 2022 / Rules and Regulations
Alternatively, replacing an MGB takes
about 100 work-hours and parts cost
about $600,000 (overhauled) for an
estimated cost of $608,500 per
helicopter.
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 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.

Airworthiness Directives; Airbus Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-10-10
for all Airbus Helicopters Model SA330J helicopters. AD 2021-10-10
required repetitively inspecting the main gearbox (MGB) particle
detector and the MGB bottom housing (oil sump) for metal particles,
analyzing any metal particles that are found, and replacing the MGB if
necessary. Since the FAA issued AD 2021-10-10, additional review
concluded that installing an improved planet gear assembly is
necessary. This AD continues to require repetitively inspecting the MGB
particle detector and the MGB bottom housing (oil sump) for metal
particles, and analyzing any metal particles that are found, and also
requires replacing the planet gear assembly and repetitively inspecting
and establishing an airworthiness limitation for that assembly as
specified in a European Union Aviation Safety Agency (EASA) AD, which
is incorporated by reference. The FAA is issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective November 15, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of November 15,
2022.

SUPPLEMENTARY INFORMATION:
[[Page 61234]]
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2021-10-10, Amendment 39-21543 (86 FR
27271, May 20, 2021) (AD 2021-10-10). AD 2021-10-10 applied to all
Airbus Helicopters Model SA330J helicopters. AD 2021-10-10 required
repetitively inspecting the MGB particle detector and the MGB bottom
housing (oil sump) for metal particles, analyzing any metal particles
that are found, and replacement of the MGB if necessary. AD 2021-10-10
was prompted by EASA AD 2018-0272, dated December 13, 2018 (EASA AD
2018-0272), 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 SA 330 J helicopters. The FAA issued AD 2021-
10-10 to address failure of an MGB second stage planet gear, which
could result in failure of the MGB and subsequent loss of control of
the helicopter.
The NPRM published in the Federal Register on July 21, 2022 (87 FR
43453). The NPRM was prompted by EASA AD 2021-0239, dated November 5,
2021 (EASA AD 2021-0239). EASA AD 2021-0239 supersedes EASA AD 2018-
0272 and continues to require repetitively inspecting the MGB particle
detector and the MGB bottom housing (oil sump) for metal particles, and
analyzing any metal particles that are found. EASA AD 2021-0239 also
requires installing an MGB equipped with a new second-stage planet gear
assembly part number (P/N) 330A32-9861-02 (mod 0751091) or modifying an
affected MGB by having the second stage planet gear assembly replaced
by an Airbus Helicopters qualified technician; and extends the
compliance time for the repetitive MGB bottom housing (oil sump)
inspections and establishes a life limit for post-mod 0751091
helicopters.
You may examine EASA AD 2021-0239 in the AD docket at
regulations.gov under Docket No. FAA-2022-0888.
In the NPRM, the FAA proposed to require accomplishing the actions
specified in EASA AD 2021-0239, described previously, as incorporated
by reference, except for any differences identified as exceptions in
the regulatory text of this AD and except as discussed under
``Differences Between this AD and the EASA AD.''
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, it has notified the FAA of the unsafe condition described in
its AD referenced above. 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 products. Except for minor editorial changes, this AD is
adopted as proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2021-0239, which supersedes EASA AD 2018-
0272 and continues to require repetitively inspecting the MGB particle
detector and the MGB bottom housing (oil sump) for metal particles, and
analyzing any metal particles that are found. EASA AD 2021-0239 also
requires installing an MGB equipped with a new second-stage planet gear
assembly P/N 330A32-9861-02 (mod 0751091) or modifying an affected MGB
by having the second stage planet gear assembly replaced by an Airbus
Helicopters qualified technician; and extends the compliance time for
the repetitive MGB bottom housing (oil sump) inspections and
establishes a life limit for post-mod 0751091 helicopters.
This material is reasonably available because the interested
parties have access to it through their normal course of business or by
the means identified in ADDRESSES.
Other Related Service Information
The FAA reviewed Airbus Helicopters Alert Service Bulletin (ASB)
No. SA330-05.103, Revision 3, dated October 4, 2021. This service
information specifies procedures for checking (inspecting) the MGB
particle detector and the bottom housing (oil sump) to ensure that
there are no particles, and for particle analysis.
The FAA also reviewed Airbus Helicopters ASB No. SA330-65.139,
Revision 0, dated October 4, 2021 (ASB SA330-65.139). This service
information specifies procedures for installing an MGB equipped with a
new second-stage planet gear assembly P/N 330A32-9861-02 (mod 0751091)
and the alternate action of having the second stage planet gear
assembly replaced by an Airbus Helicopters qualified technician. The
new second stage planet gear assembly has improved stress and fatigue
characteristics. ASB SA330-65.139 also establishes an airworthiness
limitation of 2,750 flight hours for all post-mod 0751091 planet gear
assemblies.
Differences Between This AD and the EASA AD
EASA AD 2021-0239 requires certain actions be done after the last
flight of the day or ``ALF,'' whereas this AD requires doing those
actions before the first flight of the day. EASA AD 2021-0239 requires
contacting the manufacturer if unsure about the characterization of the
particles collected, whereas this AD does not. If there are any 16NCD13
particles, EASA AD 2021-0239 requires contacting the manufacturer and
sending a 1-liter sample of oil to the manufacturer, whereas this AD
does not. EASA AD 2021-0239 requires returning certain parts to the
manufacturer, whereas this AD does not. EASA AD 2021-0239 allows the
option of modifying an affected MGB by having the second stage planet
gear assembly replaced by an Airbus Helicopters qualified technician,
whereas this AD allows that modification with certain approvals
instead. EASA AD 2021-0239 allows different methods to accomplish the
oil sump inspection, whereas this AD requires a certain method. EASA AD
2021-0239 requires discarding certain parts, whereas this AD requires
removing those parts from service instead.
Costs of Compliance
The FAA estimates that this AD affects 15 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.
Inspecting the MGB particle detector takes about 0.25 work-hour for
an estimated cost of $21 per helicopter and $315 for the U.S. fleet,
per inspection cycle. Inspecting the MGB bottom housing (oil sump)
takes up to about 4 work-hours for an estimated cost of $340 per
helicopter and $5,100 for the U.S. fleet, per inspection cycle.
Replacing a second stage planet gear assembly takes about 100 work-
hours and parts cost about $121,140 for an estimated cost of $129,640
per helicopter and $1,944,600 for the U.S. fleet, per replacement
cycle.
[[Page 61235]]
Alternatively, replacing an MGB takes about 100 work-hours and parts
cost about $600,000 (overhauled) for an estimated cost of $608,500 per
helicopter.
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 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.
