FOR FURTHER INFORMATION CONTACT: Hal Jensen, Aerospace Engineer, Operational 70359 Comments Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0046, dated February 12, 2021 (EASA AD 2021–0046) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Helicopters Model EC120B helicopters. Although EASA AD 2021–0046 applies to all Model EC120B helicopters, this AD applies to helicopters with an affected part installed instead. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2021–04–21, Amendment 39–21443 (86 FR 17278, April 2, 2021) (AD 2021–04–21). AD 2021–04–21 applied to certain Airbus Helicopters Model EC120B helicopters. The NPRM published in the Federal Register on September 23, 2021 (86 FR 52859). The NPRM was prompted by a report of broken and bent attachment bolts of the MR hub scissors assembly and a determination that additional part markings of the washer, scissor branch, and mast ring of the corresponding nut side, and repetitive inspections of those part markings, are necessary to detect any rotation. The NPRM proposed to continue to require the actions in AD 2021–04–21, as specified in an EASA AD. The NPRM also proposed to require part marking of the washer, scissor branch, and mast ring of the corresponding nut side, and repetitive inspections of the additional part markings and repair if necessary, as specified in an EASA AD. The FAA is issuing this AD to address broken and bent attachment bolts of the MR hub scissors assembly, which could lead to detachment of a MR hub scissors attachment bolt, possibly resulting in complete loss of control of the helicopter. See the MCAI for additional background information. 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. Conclusion The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for 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. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0046 specifies procedures for an inspection of the attachment bolts of the MR hub scissors assembly for discrepancies (discrepancies include corrosion, fretting, wear, cracking, bolt play, and bolt tightening torque) and repair if necessary; part marking of the washer, scissor branch, and mast ring of the attachment bolts and corresponding nut side of the MR hub scissors assembly; and repetitive inspections, after part marking, for discrepancies, and repair if necessary. The inspections of the attachment bolts of the MR hub assembly include checking the play and torque of the scissors attachment bolts and making sure that there are no hard spots in the scissors link hinge. 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 89 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS jspears on DSK121TN23PROD with RULES1 Action Labor cost Inspection for discrepancies (retained actions from AD 2021–04–21).

SUPPLEMENTARY INFORMATION:

Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0046, dated February 12, 2021 
(EASA AD 2021-0046) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Helicopters Model EC120B helicopters. Although EASA AD 
2021-0046 applies to all Model EC120B helicopters, this AD applies to 
helicopters with an affected part installed instead.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2021-04-21, Amendment 39-21443 (86 FR 
17278, April 2, 2021) (AD 2021-04-21). AD 2021-04-21 applied to certain 
Airbus Helicopters Model EC120B helicopters. The NPRM published in the 
Federal Register on September 23, 2021 (86 FR 52859). The NPRM was 
prompted by a report of broken and bent attachment bolts of the MR hub 
scissors assembly and a determination that additional part markings of 
the washer, scissor branch, and mast ring of the corresponding nut 
side, and repetitive inspections of those part markings, are necessary 
to detect any rotation. The NPRM proposed to continue to require the 
actions in AD 2021-04-21, as specified in an EASA AD. The NPRM also 
proposed to require part marking of the washer, scissor branch, and 
mast ring of the corresponding nut side, and repetitive inspections of 
the additional part markings and repair if necessary, as specified in 
an EASA AD.
    The FAA is issuing this AD to address broken and bent attachment 
bolts of the MR hub scissors assembly, which could lead to detachment 
of a MR hub scissors attachment bolt, possibly resulting in complete 
loss of control of the helicopter. See the MCAI for additional 
background information.

Discussion of Final Airworthiness Directive

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.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for 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.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0046 specifies procedures for an inspection of the 
attachment bolts of the MR hub scissors assembly for discrepancies 
(discrepancies include corrosion, fretting, wear, cracking, bolt play, 
and bolt tightening torque) and repair if necessary; part marking of 
the washer, scissor branch, and mast ring of the attachment bolts and 
corresponding nut side of the MR hub scissors assembly; and repetitive 
inspections, after part marking, for discrepancies, and repair if 
necessary. The inspections of the attachment bolts of the MR hub 
assembly include checking the play and torque of the scissors 
attachment bolts and making sure that there are no hard spots in the 
scissors link hinge.
    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 89 helicopters of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

    The FAA estimates that it would take about 1 hour per product to 
comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, the FAA estimates the 
cost of reporting on U.S. operators to be $7,565, or $85 per product.
    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:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to 
Information Collection Clearance Officer, Federal Aviation 
Administration, 10101 Hillwood Pkwy., Fort Worth, TX 76177-1524.

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.
