SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Airbus Helicopters Model
AS350B, AS350BA, AS350B1,
AS350B2, AS350B3, and AS350D
helicopters; Model AS355E, AS355F,
AS355F1, AS355F2, AS355N, and
AS355NP helicopters; and Model EC130
B4 and EC130 T2 helicopters. The
VerDate Sep<11>2014
16:13 Mar 09, 2021
Jkt 253001
NPRM published in the Federal
Register on September 21, 2020 (85 FR
59217). The NPRM proposed to require
a one-time inspection to verify the
presence and correct installation of the
MRM upper bearing retaining rings, a
repetitive inspection of the sealant bead
on the MRM for damage, and corrective
actions if necessary. The proposed
requirements were intended to detect,
and correct if applicable, a missing
retaining ring of the inner race of the
MRM upper bearing. The FAA is issuing
this AD to address this condition,
which, if not detected and corrected,
can lead to damage to the MRM and
surrounding elements, possibly
resulting in loss of control of the
helicopter.
The NPRM was prompted by EASA
AD 2018–0206, dated September 20,
2018 (EASA AD 2018–0206), issued by
EASA, which is the Technical Agent for
the Member States of the European
Union, to correct an unsafe condition
for certain Airbus Helicopters Model
AS350B, AS350BA, AS350BB,
AS350B1, AS350B2, AS350B3, and
AS350D helicopters; Model AS355E,
AS355F, AS355F1, AS355F2, AS355N,
and AS355NP helicopters; and Model
EC130 B4 and EC130 T2 helicopters.
Model AS355BB helicopters are not
certificated by the FAA and are not
included on the U.S. type certificate
data sheet; this AD therefore does not
include those helicopters in the
applicability. EASA advises that during
a scheduled inspection on an Airbus
Helicopters Model AS350B3 helicopter,
one of the two retaining rings of the
inner race of the MRM upper bearing
was found missing. These two retaining
rings ensure that the inner race is
correctly positioned with respect to the
rollers, and, if one or both of these
retaining rings are missing, it can lead
to an unlimited shift of the inner race
and compromise the function of the
MRM upper bearing. This condition, if
not detected and corrected, can lead to
damage to the MRM and surrounding
elements, possibly resulting in loss of
control of the helicopter.
Airbus Helicopters developed an
inspection to check that the upper and
lower retaining rings of the inner race of
the MRM upper bearing are present and
correctly installed. EASA determined
that the same condition may exist or
develop on Airbus Helicopters Model
AS350 helicopters, Model AS355
helicopters, and Model EC130
helicopters because they share a similar
design and supply chain. Until the
check of the upper and lower bearing
retaining rings is accomplished, EASA
specifies that repetitive inspections of
the MRM upper bearing sealant bead
PO 00000
Frm 00006
Fmt 4700
Sfmt 4700
(sealant bead) should be accomplished
to ensure the MRM remains serviceable.
EASA considers its AD an interim
measure pending further investigation
results, and notes that further AD action
may follow.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The FAA received 4
comments in support of the NPRM.
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 issuing
this AD after evaluating all of the
information provided by EASA and
determining the unsafe condition exists
and is likely to exist or develop on other
helicopters of the same type design and
that air safety and the public interest
require adopting the AD requirements as
proposed.
Differences Between This AD and the
EASA AD
Although EASA AD 2018–0206
specifies accomplishing the inspection
of the installation of the MRM upper
bearing inner race retaining rings within
660 hours time in service (TIS) or 24
months, whichever occurs first, the FAA
has determined that interval does not
address the identified unsafe condition
soon enough to ensure an adequate level
of safety for the affected fleet. In
developing an appropriate compliance
time for this AD, the FAA considered
the degree of urgency associated with
the subject unsafe condition and the
manufacturer’s recommendation. In
light of all of these factors, the FAA
finds that a compliance time of within
660 hours TIS or 6 months, whichever
occurs first, represents an appropriate
interval of time for affected helicopters
to continue to operate without
compromising safety.
Although paragraph (5) of EASA AD
2018–0206 specifies that operators may
contact the manufacturer for
instructions if there are signs of
degradation on the MRM inner race,
paragraph (i)(3) of this AD requires
operators to repair or replace the MRM
if there is any degradation as indicated
by damage to the retaining rings
(including but not limited to cracks,
scratches, and gouges), deterioration, or
wear.

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:
Discussion
The FAA issued AD 2020–23–02,
Amendment 39–21318 (85 FR 73607,
November 19, 2020) (AD 2020–23–02),
which applied to all Airbus Helicopters
Model EC225LP helicopters. AD 2020–
23–02 required repetitive inspections of
the bearing in the swashplate assembly
of the main rotor mast assembly for
discrepancies (ceramic balls that have a
hard point or sensitive axial play or
both) and, depending on the findings,
replacement of an affected main rotor
mast assembly with a serviceable main
rotor mast assembly. The FAA issued
AD 2020–23–02 to address defective
ceramic balls in the bearing installed in
the swashplate assembly of the main
rotor mast assembly, which could lead
to premature spalling of the ball itself
and of the bearing, loss of function of
the bearing, and overload of the main
rotor mast scissor, resulting in reduced
control of the helicopter.
Actions Since AD 2020–23–02 Was
Issued
Since the FAA issued AD 2020–23–
02, the FAA has determined that
additional main rotor mast assemblies
are affected by the unsafe condition.
The EASA, which is the Technical
Agent for the Member States of the
European Union, has issued EASA AD
2020–0264, dated December 2, 2020
(EASA AD 2020–0264) (also referred to
as the Mandatory Continuing
Airworthiness Information, or the
MCAI), to correct an unsafe condition
for all Airbus Helicopters Model
EC225LP helicopters. EASA AD 2020–
0264 supersedes EASA AD 2020–0079,
dated April 1, 2020 (which corresponds
to FAA AD 2020–23–02).
This AD was prompted by a report of
a manufacturing and control issue
regarding the ceramic balls in the
bearing installed in the swashplate
assembly of the main rotor mast
assembly. The FAA is issuing this AD
to address defective ceramic balls in the
bearing installed in the swashplate
assembly of the main rotor mast
assembly, which could lead to
premature spalling of the ball itself and
of the bearing, loss of function of the
bearing, and overload of the main rotor
mast scissor, resulting in reduced
control of the helicopter. See the MCAI
for additional background information.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Airbus Helicopters
Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, and AS350D
helicopters; Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and
AS355NP helicopters; and Model EC130 B4 and EC130 T2 helicopters. The
NPRM published in the Federal Register on September 21, 2020 (85 FR
59217). The NPRM proposed to require a one-time inspection to verify
the presence and correct installation of the MRM upper bearing
retaining rings, a repetitive inspection of the sealant bead on the MRM
for damage, and corrective actions if necessary. The proposed
requirements were intended to detect, and correct if applicable, a
missing retaining ring of the inner race of the MRM upper bearing. The
FAA is issuing this AD to address this condition, which, if not
detected and corrected, can lead to damage to the MRM and surrounding
elements, possibly resulting in loss of control of the helicopter.
The NPRM was prompted by EASA AD 2018-0206, dated September 20,
2018 (EASA AD 2018-0206), issued by EASA, which is the Technical Agent
for the Member States of the European Union, to correct an unsafe
condition for certain Airbus Helicopters Model AS350B, AS350BA,
AS350BB, AS350B1, AS350B2, AS350B3, and AS350D helicopters; Model
AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters; and
Model EC130 B4 and EC130 T2 helicopters. Model AS355BB helicopters are
not certificated by the FAA and are not included on the U.S. type
certificate data sheet; this AD therefore does not include those
helicopters in the applicability. EASA advises that during a scheduled
inspection on an Airbus Helicopters Model AS350B3 helicopter, one of
the two retaining rings of the inner race of the MRM upper bearing was
found missing. These two retaining rings ensure that the inner race is
correctly positioned with respect to the rollers, and, if one or both
of these retaining rings are missing, it can lead to an unlimited shift
of the inner race and compromise the function of the MRM upper bearing.
This condition, if not detected and corrected, can lead to damage to
the MRM and surrounding elements, possibly resulting in loss of control
of the helicopter.
Airbus Helicopters developed an inspection to check that the upper
and lower retaining rings of the inner race of the MRM upper bearing
are present and correctly installed. EASA determined that the same
condition may exist or develop on Airbus Helicopters Model AS350
helicopters, Model AS355 helicopters, and Model EC130 helicopters
because they share a similar design and supply chain. Until the check
of the upper and lower bearing retaining rings is accomplished, EASA
specifies that repetitive inspections of the MRM upper bearing sealant
bead (sealant bead) should be accomplished to ensure the MRM remains
serviceable. EASA considers its AD an interim measure pending further
investigation results, and notes that further AD action may follow.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received 4 comments in support of
the NPRM.
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 issuing this AD after
evaluating all of the information provided by EASA and determining the
unsafe condition exists and is likely to exist or develop on other
helicopters of the same type design and that air safety and the public
interest require adopting the AD requirements as proposed.
Differences Between This AD and the EASA AD
Although EASA AD 2018-0206 specifies accomplishing the inspection
of the installation of the MRM upper bearing inner race retaining rings
within 660 hours time in service (TIS) or 24 months, whichever occurs
first, the FAA has determined that interval does not address the
identified unsafe condition soon enough to ensure an adequate level of
safety for the affected fleet. In developing an appropriate compliance
time for this AD, the FAA considered the degree of urgency associated
with the subject unsafe condition and the manufacturer's
recommendation. In light of all of these factors, the FAA finds that a
compliance time of within 660 hours TIS or 6 months, whichever occurs
first, represents an appropriate interval of time for affected
helicopters to continue to operate without compromising safety.
Although paragraph (5) of EASA AD 2018-0206 specifies that
operators may contact the manufacturer for instructions if there are
signs of degradation on the MRM inner race, paragraph (i)(3) of this AD
requires operators to repair or replace the MRM if there is any
degradation as indicated by damage to the retaining rings (including
but not limited to cracks, scratches, and gouges), deterioration, or
wear.

Costs of Compliance
The FAA estimates that this AD affects 1,212 helicopters of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 30 work-hours x $85 per hour = Up $0 Up to $2,550.............. Up to $3,090,600.
to $2,550.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 80 work-hours x $85 per Up to $33,124..... Up to $39,924.

------------------------------------------------------------------------
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.
