VerDate Sep<11>2014 16:24 Mar 25, 2021 Jkt 253001 SUPPLEMENTARY INFORMATION: Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0022R2, dated December 23, 2020 (EASA AD 2020–0022R2) (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. 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 AS332L, AS332L1, AS332C, and AS332C1 helicopters. The NPRM published in the Federal Register on December 21, 2020 (85 FR 82977). The NPRM 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 NPRM proposed to 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 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 applying corrective actions if necessary as specified in an EASA AD. The FAA is issuing 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. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public. New EASA AD In the NPRM, the FAA referred to EASA AD 2020–0022R1, dated September 18, 2020 (EASA AD 2020– PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 0022R1). Since the NPRM was issued, EASA issued EASA AD 2020–0022R2, which extends the compliance time for installation of the FFMP. The FAA determined that no additional work is required for helicopters that have accomplished the actions as required by EASA AD 2020– 0022R1. Therefore, the FAA has revised all applicable sections in this final rule to also specify EASA AD 2020–0022R2. Conclusion The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. The FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 EASA ADs 2020–0022R1 and 2020– 0022R2 describe procedures for 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 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. These documents are distinct since EASA AD 2020–0022R2 extends the compliance time for installation of the FFMP. 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. Costs of Compliance The FAA estimates that this AD affects 11 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\26MRR1.SGM 26MRR1 Federal Register / Vol. 86, No. 57 / Friday, March 26, 2021 / Rules and Regulations 16045 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 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. khammond on DSKJM1Z7X2PROD with RULES 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.

SUPPLEMENTARY INFORMATION: This amendment to part 95 of the Federal Aviation Regulations (14 CFR part 95) amends, suspends, or revokes IFR altitudes governing the operation of all aircraft in flight over a specified route or any portion of that route, as well as the changeover points (COPs) for Federal airways, jet routes, or direct routes as prescribed in part 95. The Rule The specified IFR altitudes, when used in conjunction with the prescribed changeover points for those routes, ensure navigation aid coverage that is adequate for safe flight operations and free of frequency interference. The reasons and circumstances that create the need for this amendment involve matters of flight safety and operational efficiency in the National Airspace System, are related to published aeronautical charts that are essential to the user, and provide for the safe and efficient use of the navigable airspace. In addition, those various reasons or circumstances require making this amendment effective before the next scheduled charting and publication date of the flight information to assure its timely availability to the user. The effective date of this amendment reflects those considerations. In view of the close and immediate relationship between these regulatory changes and safety in air commerce, I find that notice and public procedure before adopting this amendment are impracticable and contrary to the public interest and that good cause exists for making the amendment effective in less than 30 days.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0022R2, dated December 23, 2020 
(EASA AD 2020-0022R2) (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.
    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 AS332L, AS332L1, AS332C, and AS332C1 helicopters. The NPRM 
published in the Federal Register on December 21, 2020 (85 FR 82977). 
The NPRM 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 NPRM proposed 
to 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 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 applying 
corrective actions if necessary as specified in an EASA AD.
    The FAA is issuing 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.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

New EASA AD

    In the NPRM, the FAA referred to EASA AD 2020-0022R1, dated 
September 18, 2020 (EASA AD 2020-0022R1). Since the NPRM was issued, 
EASA issued EASA AD 2020-0022R2, which extends the compliance time for 
installation of the FFMP.
    The FAA determined that no additional work is required for 
helicopters that have accomplished the actions as required by EASA AD 
2020-0022R1. Therefore, the FAA has revised all applicable sections in 
this final rule to also specify EASA AD 2020-0022R2.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule with the 
changes described previously and minor editorial changes. The FAA has 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    The FAA also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    EASA ADs 2020-0022R1 and 2020-0022R2 describe procedures for 
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 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. These documents are distinct since EASA AD 2020-
0022R2 extends the compliance time for installation of the FFMP.
    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.

Costs of Compliance

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

[[Page 16045]]



                                      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 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

    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.
