Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0022R1, dated September 18, 2020 (EASA AD 2020–0022R1) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Helicopters Model AS332L, AS332L1, AS332C, and AS332C1 helicopters. This proposed AD was prompted by the failure of a second stage planet gear installed in the MGB of an Airbus Helicopters Model EC225LP helicopter. Airbus Helicopters Model AS332L, AS332L1, AS332C, and AS332C1 helicopters have a similar design to the affected Model EC225LP helicopter, therefore, these models may be subject to the unsafe condition revealed on the Model EC225LP helicopter. The FAA is proposing this AD to address failure of a second stage planet gear installed in the MGB, which could result in failure of the MGB and subsequent loss of control of the helicopter. See the MCAI for additional background information. PO 00000 Frm 00029 Fmt 4702 Sfmt 4702 Related Service Information Under 1 CFR Part 51 EASA AD 2020–0022R1 describes procedures for identifying the part number of each second stage planet gear assembly installed in the MGB, replacing a MGB having certain second stage plane gear assembly part numbers with a serviceable MGB, modifying the helicopter by installing an FFMP, repetitively inspecting the FFMP and the MGB bottom housing and conical housing for metal particles, analyzing any metal particles that are found, and applicable corrective actions. The corrective actions include replacing an affected MGB with a serviceable MGB. 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 the ADDRESSES section. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because the FAA evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2020–0022R1, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2020–0022R1 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2020– 0022R1 in its entirety, through that incorporation, except for any differences E:\FR\FM\21DEP1.SGM 21DEP1 Federal Register / Vol. 85, No. 245 / Monday, December 21, 2020 / Proposed Rules not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in the EASA AD. Service information specified in EASA AD 2020–0022R1 that is required for compliance with EASA AD 2020– 0022R1 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is 82979 FAA–2020–1136 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 11 helicopters of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 8.50 work-hours × $85 per hour = $722.50 ................................................................................ $17,625 $18,347.50 $201,822.50 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on number of helicopters that might need these on-condition actions: the results of any required actions. The FAA has no way of determining the ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 40.50 work-hour × $85 per hour = $3,442.50 ............................ $275,000 (overhauled part) ....................................................... $278,442.50 According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. The FAA does not control warranty coverage for affected operators. As a result, the FAA has included all known costs in the cost estimate. 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. 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 this proposed regulation: (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES Regulatory Findings The FAA determined that this proposed AD would not have federalism implications under Executive Order VerDate Sep<11>2014 21:22 Dec 18, 2020 Jkt 253001 1.

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus Helicopters Model AS332L, AS332L1, AS332C, and AS332C1 
helicopters. This proposed AD was prompted by the failure of a second 
stage planet gear installed in the main gearbox (MGB). This proposed AD 
would require identifying the part number of each second stage planet 
gear assembly installed in the MGB, replacing an MGB having certain 
second stage planet gear assembly part numbers with a serviceable MGB, 
modifying the helicopter by installing a full flow magnetic plug 
(FFMP), repetitively inspecting the FFMP and the MGB bottom housing and 
conical housing for metal particles, analyzing any metal particles that 
are found, and applying corrective actions if necessary, as specified 
in a European Union Aviation Safety Agency (EASA) AD, which is proposed 
for incorporation by reference. 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 February 4, 
2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0022R1, dated September 18, 
2020 (EASA AD 2020-0022R1) (also referred to as the Mandatory 
Continuing Airworthiness Information, or the MCAI), to correct an 
unsafe condition for all Airbus Helicopters Model AS332L, AS332L1, 
AS332C, and AS332C1 helicopters. This proposed AD was prompted by the 
failure of a second stage planet gear installed in the MGB of an Airbus 
Helicopters Model EC225LP helicopter. Airbus Helicopters Model AS332L, 
AS332L1, AS332C, and AS332C1 helicopters have a similar design to the 
affected Model EC225LP helicopter, therefore, these models may be 
subject to the unsafe condition revealed on the Model EC225LP 
helicopter. The FAA is proposing this AD to address failure of a second 
stage planet gear installed in the MGB, which could result in failure 
of the MGB and subsequent loss of control of the helicopter. See the 
MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0022R1 describes procedures for identifying the part 
number of each second stage planet gear assembly installed in the MGB, 
replacing a MGB having certain second stage plane gear assembly part 
numbers with a serviceable MGB, modifying the helicopter by installing 
an FFMP, repetitively inspecting the FFMP and the MGB bottom housing 
and conical housing for metal particles, analyzing any metal particles 
that are found, and applicable corrective actions. The corrective 
actions include replacing an affected MGB with a serviceable MGB.
    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 the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the FAA 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2020-0022R1, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2020-
0022R1 will be incorporated by reference in the FAA final rule. This 
proposed AD would, therefore, require compliance with EASA AD 2020-
0022R1 in its entirety, through that incorporation, except for any 
differences

[[Page 82979]]

identified as exceptions in the regulatory text of this proposed AD. 
Using common terms that are the same as the heading of a particular 
section in the EASA AD does not mean that operators need comply only 
with that section. For example, where the AD requirement refers to 
``all required actions and compliance times,'' compliance with this AD 
requirement is not limited to the section titled ``Required Action(s) 
and Compliance Time(s)'' in the EASA AD. Service information specified 
in EASA AD 2020-0022R1 that is required for compliance with EASA AD 
2020-0022R1 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
1136 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 11 helicopters of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
8.50 work-hours x $85 per hour = $722.50.....................         $17,625       $18,347.50      $201,822.50
----------------------------------------------------------------------------------------------------------------

    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 
helicopters that might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
           Labor cost                  Parts cost            product
------------------------------------------------------------------------
40.50 work-hour x $85 per hour   $275,000 (overhauled       $278,442.50
 = $3,442.50.                     part).
------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators. The FAA does not control warranty 
coverage for affected operators. As a result, the FAA has included all 
known costs in the cost estimate.

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 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 this proposed 
regulation:
    (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.

List of Subjects in 14 CFR Part 39
