Federal Register / Vol. 83, No. 150 / Friday, August 3, 2018 / Rules and Regulations
(10) The Instructions for Continued
Airworthiness (ICA) required by
§ 23.1529 must contain maintenance
requirements to ensure that the battery
has been sufficiently charged at
appropriate intervals specified by the
battery manufacturer and the equipment
manufacturer that contain the
rechargeable lithium battery or
rechargeable lithium battery system.
The lithium rechargeable batteries and
lithium rechargeable battery systems
must not degrade below specified
ampere-hour levels sufficient to power
the aircraft system. The ICA must also
contain procedures for the maintenance
of replacement batteries to prevent the
installation of batteries that have
degraded charge retention ability or
other damage due to prolonged storage
at a low state of charge. Replacement
batteries must be of the same
manufacturer and part number as
approved by the FAA.
Note 2 to paragraph (10): Maintenance
requirements include procedures that check
battery capacity, charge degradation at
manufacturers recommended inspection
intervals, and replace batteries at
manufacturer’s recommended replacement
schedule/time to prevent age-related
degradation.
Note 3 to paragraph (10): The term
‘‘sufficiently charged’’ means that the battery
must retain enough charge, expressed in
ampere-hours, to ensure that the battery cells
will not be damaged. A battery cell may be
damaged by low charge (i.e., below a certain
level), resulting in a reduction in the ability
to charge and retain a full charge. This
reduction would be greater than the
reduction that may result from normal
operational degradation.
Note 4 to paragraph (10): Replacement
battery in spares storage may be subject to
prolonged storage at a low state of charge.

Discussion
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA Emergency AD
No. 2017–0046–E, dated March 10,
2017, to correct an unsafe condition for
Leonardo (previously Finmeccanica
S.p.A, AgustaWestland S.p.A.) Model
A109E, A109LUH, A109S, and
E:\FR\FM\03AUR1.SGM

AW109SP helicopters. EASA advises
that during inspections of two
AW109SP helicopters, degraded
bearings, part number (P/N)
109G6320L01–101, were discovered on
the engine and transmission oil cooling
system pulley assembly, P/N
109G6320A26–101. EASA further states
that because of this condition, both fan
assemblies could cease to function,
resulting in engine power loss,
transmission failure, and loss of control
of the helicopter. To correct this unsafe
condition, the EASA AD requires a onetime inspection of each pulley assembly
bearing and replacing each fan
assembly.
fan assembly with fan assembly P/N
109–0455–01–101 before further flight.
If there is no play, no rotation
resistance, and no binding, this AD
requires replacing each fan assembly
with fan assembly P/N 109–0455–01–
101 within 20 hours TIS.
Finally, this AD prohibits installing
fan assembly P/N 109–0455–01–103 on
any helicopter.
FAA’s Determination
These helicopters have been approved
by the aviation authority of Italy and are
approved for operation in the United
States. Pursuant to our bilateral
agreement with Italy, EASA, its
technical representative, has notified us
of the unsafe condition described in the
EASA AD. We are issuing this AD
because we evaluated all information
provided by EASA and determined the
unsafe condition exists and is likely to
exist or develop on other helicopters of
these same type designs.
Costs of Compliance
We estimate that this AD affects 127
helicopters of U.S. Registry. We estimate
that operators may incur the following
costs in order to comply with this AD.
At an average labor rate of $85 per
work-hour, inspecting the bearings will
require 1 hour, for a cost per helicopter
of $85. Replacing both fan assemblies
will require 8 hours and $44,800 for
parts. Based on these figures, we
estimate a total cost of $45,565 per
helicopter and $5,786,755 for the U.S.
fleet to comply with this AD.
According to the Leonardo service
information, some of the costs of this
AD may be covered under warranty,
thereby reducing the cost impact on
affected individuals. We do not control
warranty coverage by Leonardo.
Accordingly, we have included all costs
in our cost estimate.

Emergency Alert Service Bulletin
(EASB) No. 109–EP–153 for Model
A109E helicopters, EASB No. 109S–075
for Model A109S helicopters, and EASB
No. 109SP–112 for Model AW109SP
helicopters, all dated March 8, 2017.
This service information contains
procedures for inspecting each pulley
assembly bearing P/N 109G6320L01–
101 for grease shield damage or leaking
grease and axial and radial play, and
freedom of rotation of the bearing. This
service information also provides
procedures for replacing each fan
assembly P/N 109–0455–01–103 with a
fan assembly P/N 109–0455–01–101.
AD Requirements
This AD requires, within 5 hours
time-in-service (TIS), inspecting with a
borescope each bearing P/N
109G6320L01–101 grease shield for a
crack, position of the grease shield, and
leaking grease. If there is a crack or
leaking grease or if the grease shield is
out of position, this AD requires
replacing each fan assembly with fan
assembly P/N 109–0455–01–101 before
further flight.
This AD also requires inspecting each
bearing for axial and radial play and
freedom of rotation. If there is any axial
or radial play, rotation resistance, or
binding, this AD requires replacing each

Differences Between This AD and the
EASA AD
The EASA AD applies to Model
A109LUH helicopters; this AD does not
as this model is a military model and
does not have an FAA type certificate.
FAA’s Justification and Determination
of the Effective Date
An unsafe condition exists that
requires the immediate adoption of this
AD without providing an opportunity
for public comments prior to adoption.
The FAA has found that the risk to the
flying public justifies waiving notice
and comment prior to adoption of this
rule because the previously described
unsafe condition can adversely affect
the controllability of the helicopter and
the initial required corrective action
must be accomplished within 5 hours
TIS. Therefore, we find good cause that
notice and opportunity for prior public
comment are impracticable.
In addition, for the reason stated
above, we find that good cause exists for
making this amendment effective in less
than 30 days.
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:
PO 00000
Frm 00005
Fmt 4700
Sfmt 4700
38015
Aviation Programs,’’ describes in more
detail the scope of the Agency’s
authority.
We are 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
We 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, I certify
that this AD:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in
Alaska to the extent that it justifies
making a regulatory distinction; and
4. 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.
We prepared an economic evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

AW109SP helicopters, degraded bearings, part number (P/N) 109G6320L01-
101, were discovered on the engine and transmission oil cooling system
pulley assembly, P/N 109G6320A26-101. EASA further states that because
of this condition, both fan assemblies could cease to function,
resulting in engine power loss, transmission failure, and loss of
control of the helicopter. To correct this unsafe condition, the EASA
AD requires a one-time inspection of each pulley assembly bearing and
replacing each fan assembly.
FAA's Determination
These helicopters have been approved by the aviation authority of
Italy and are approved for operation in the United States. Pursuant to
our bilateral agreement with Italy, EASA, its technical representative,
has notified us of the unsafe condition described in the EASA AD. We
are issuing this AD because we evaluated all information provided by
EASA and determined the unsafe condition exists and is likely to exist
or develop on other helicopters of these same type designs.
Related Service Information
We reviewed Leonardo Helicopters Emergency Alert Service Bulletin
(EASB) No. 109-EP-153 for Model A109E helicopters, EASB No. 109S-075
for Model A109S helicopters, and EASB No. 109SP-112 for Model AW109SP
helicopters, all dated March 8, 2017. This service information contains
procedures for inspecting each pulley assembly bearing P/N 109G6320L01-
101 for grease shield damage or leaking grease and axial and radial
play, and freedom of rotation of the bearing. This service information
also provides procedures for replacing each fan assembly P/N 109-0455-
01-103 with a fan assembly P/N 109-0455-01-101.
AD Requirements
This AD requires, within 5 hours time-in-service (TIS), inspecting
with a borescope each bearing P/N 109G6320L01-101 grease shield for a
crack, position of the grease shield, and leaking grease. If there is a
crack or leaking grease or if the grease shield is out of position,
this AD requires replacing each fan assembly with fan assembly P/N 109-
0455-01-101 before further flight.
This AD also requires inspecting each bearing for axial and radial
play and freedom of rotation. If there is any axial or radial play,
rotation resistance, or binding, this AD requires replacing each fan
assembly with fan assembly P/N 109-0455-01-101 before further flight.
If there is no play, no rotation resistance, and no binding, this AD
requires replacing each fan assembly with fan assembly P/N 109-0455-01-
101 within 20 hours TIS.
Finally, this AD prohibits installing fan assembly P/N 109-0455-01-
103 on any helicopter.
Differences Between This AD and the EASA AD
The EASA AD applies to Model A109LUH helicopters; this AD does not
as this model is a military model and does not have an FAA type
certificate.
Costs of Compliance
We estimate that this AD affects 127 helicopters of U.S. Registry.
We estimate that operators may incur the following costs in order to
comply with this AD.
At an average labor rate of $85 per work-hour, inspecting the
bearings will require 1 hour, for a cost per helicopter of $85.
Replacing both fan assemblies will require 8 hours and $44,800 for
parts. Based on these figures, we estimate a total cost of $45,565 per
helicopter and $5,786,755 for the U.S. fleet to comply with this AD.
According to the Leonardo service information, some of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected individuals. We do not control warranty coverage by
Leonardo. Accordingly, we have included all costs in our cost estimate.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because the previously described unsafe condition can adversely affect
the controllability of the helicopter and the initial required
corrective action must be accomplished within 5 hours TIS. Therefore,
we find good cause that notice and opportunity for prior public comment
are impracticable.
In addition, for the reason stated above, we find that good cause
exists for making this amendment effective in less than 30 days.
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.
We are 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
We 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, I certify that this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska to the extent that
it justifies making a regulatory distinction; and
4. 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.
We prepared an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.
