Download as PDF 38014 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. Issued in Kansas City, Missouri, on July 25, 2018.

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 03AUR1 Federal Register / Vol. 83, No. 150 / Friday, August 3, 2018 / Rules and Regulations 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. amozie on DSK3GDR082PROD with RULES 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 VerDate Sep<11>2014 23:08 Aug 02, 2018 Jkt 244001 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.

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

[[Page 38015]]

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 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.

assembly) part number (P/N) 109-0455-01-103 installed, certificated 
in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as failure of an oil cooler 
system pulley assembly (pulley assembly) bearing. This condition 
could lead to failure of a fan assembly, resulting in engine power 
loss, transmission failure, and loss of control of the helicopter.

(c) Effective Date

    This AD becomes effective August 20, 2018.

 (d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    (1) Within 5 hours time-in-service (TIS), remove the fan belt 
from each pulley assembly and, using a borescope inspect the grease 
shield of each bearing P/N 109G6320L01-101 for a crack, leaking 
grease, and position of the grease shield.
    (i) If there is a crack, any leaking grease, or if the grease 
shield is out of position, before further flight, replace each fan 
assembly P/N 109-0455-01-103 on both sides of the helicopter with a
