SUPPLEMENTARY INFORMATION: Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0084, dated April 3, 2020 (EASA AD 2020–0084) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Helicopters Deutschland GmbH Model MBB–BK117 D–2 helicopters. Although EASA AD 2020–0084 applies to all Model MBB–BK117 D–2 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 by adding an AD that would apply to certain Model MBB–BK117 D– 2 helicopters. The NPRM published in the Federal Register on March 8, 2021 (86 FR 13234). The NPRM was prompted by reports that collective lever switch units having certain part numbers did not have retaining rings installed in the cable cut switch guard. The NPRM proposed to require inspecting certain collective lever switch units for discrepancies (missing retaining rings, incorrectly installed retaining rings, and a missing axis in the cable cut switch guard), doing all applicable corrective actions, and marking affected parts. The cable cut switch guard has an axis that holds, and allows the guard to turn over, the cable cut switch. This axis is secured with two retaining rings and if both retaining rings are missing, the axis can move out. The FAA is issuing this AD to address this condition, which could cause inadvertent activation of the rescue hoist cable cut function, resulting in personal injury. 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 and an update to paragraph (j)(1) of this AD. 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 2020–0084 specifies procedures for inspecting collective lever switch units having certain part numbers for discrepancies, applicable corrective actions, and marking affected parts. Discrepancies include missing retaining rings, incorrectly installed retaining rings, and a missing axis in the cable cut switch guard. Corrective actions include installing missing retaining rings, adjusting retaining rings that are installed incorrectly, and installing an axis in the cable cut switch guard. EASA AD 2020–0084 also specifies that an affected part can be installed on any helicopter, provided it has been marked. 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 30 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 0.50 work-hour × $85 per hour = $42.50 .................................................................................... $0 $42.50 $1,275 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: jbell on DSKJLSW7X2PROD with RULES ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 2 work-hours × $85 per hour = $170 ...................................................................................................................... $56 $226 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. VerDate Sep<11>2014 16:41 May 28, 2021 Jkt 253001 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, PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 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 E:\FR\FM\01JNR1.SGM 01JNR1 Federal Register / Vol. 86, No. 103 / Tuesday, June 1, 2021 / Rules and Regulations 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.

SUPPLEMENTARY INFORMATION:

Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0084, dated April 3, 2020 (EASA 
AD 2020-0084) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Helicopters Deutschland GmbH Model MBB-BK117 D-2 
helicopters. Although EASA AD 2020-0084 applies to all Model MBB-BK117 
D-2 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 by adding an AD that would apply to certain Model MBB-BK117 
D-2 helicopters. The NPRM published in the Federal Register on March 8, 
2021 (86 FR 13234). The NPRM was prompted by reports that collective 
lever switch units having certain part numbers did not have retaining 
rings installed in the cable cut switch guard. The NPRM proposed to 
require inspecting certain collective lever switch units for 
discrepancies (missing retaining rings, incorrectly installed retaining 
rings, and a missing axis in the cable cut switch guard), doing all 
applicable corrective actions, and marking affected parts.
    The cable cut switch guard has an axis that holds, and allows the 
guard to turn over, the cable cut switch. This axis is secured with two 
retaining rings and if both retaining rings are missing, the axis can 
move out. The FAA is issuing this AD to address this condition, which 
could cause inadvertent activation of the rescue hoist cable cut 
function, resulting in personal injury. 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 and an update to paragraph (j)(1) of 
this AD. 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 2020-0084 specifies procedures for inspecting collective 
lever switch units having certain part numbers for discrepancies, 
applicable corrective actions, and marking affected parts. 
Discrepancies include missing retaining rings, incorrectly installed 
retaining rings, and a missing axis in the cable cut switch guard. 
Corrective actions include installing missing retaining rings, 
adjusting retaining rings that are installed incorrectly, and 
installing an axis in the cable cut switch guard. EASA AD 2020-0084 
also specifies that an affected part can be installed on any 
helicopter, provided it has been marked. 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 30 helicopters of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
0.50 work-hour x $85 per hour = $42.50.......................              $0           $42.50           $1,275
----------------------------------------------------------------------------------------------------------------

    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
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170....             $56             $226
------------------------------------------------------------------------

    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.

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.

The Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2021-10-18 Airbus Helicopters Deutschland GmbH: Amendment 39-1551; 
Docket No. FAA-2021-0104; Project Identifier MCAI-2020-00477-R.

(a) Effective Date

    This airworthiness directive (AD) is effective July 6, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Helicopters Deutschland GmbH Model 
MBB-BK117 D-2 helicopters, certificated in any category, all serial 
numbers, having an affected part defined in European Union Aviation 
Safety Agency (EASA) AD 2020-0084, dated April 3, 2020 (EASA AD 
2020-0084).

(d) Subject

    Joint Aircraft System Component (JASC) Code 2700, Flight Control 
System.

(e) Reason

    This AD was prompted by reports that collective lever switch 
units having certain part numbers did not have retaining rings 
installed in the cable cut switch guard. The cable cut switch guard 
has an axis that holds, and allows the guard to turn over, the cable 
cut switch. This axis is secured with two retaining rings and if 
both retaining rings are missing, the axis can move out. The FAA is 
issuing this AD to address this condition, which could cause 
inadvertent activation of the rescue hoist cable cut function, 
resulting in personal injury.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Comply with all required actions and compliance times specified 
in, and in accordance with, EASA AD 2020-0084.

(h) Exceptions to EASA AD 2020-0084

    (1) Where EASA AD 2020-0084 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2020-0084 does not apply 
to this AD.

(i) Special Flight Permit

    Special flight permits may be issued in accordance with 14 CFR 
21.197 and 21.199 to operate the helicopter to a location where the 
helicopter can be modified (if the operator elects to do so), 
provided the helicopter is not used for hoist operations.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the manager of the International Validation Branch, send 
it to the attention of the person identified in paragraph (k) of 
this AD. Information may be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
