SUPPLEMENTARY INFORMATION: khammond on DSKJM1Z7X2PROD with RULES Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0198, dated August 15, 2019 (EASA AD 2019– 0198), to correct an unsafe condition for all Airbus Helicopters Deutschland GmbH (AHD), formerly Eurocopter Deutschland GmbH, Model MBB–BK117 D–2 helicopters. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Airbus Helicopters Deutschland GmbH Model MBB–BK 117 D–2 helicopters. The NPRM published in the Federal Register on April 2, 2021 (86 FR 17322). The NPRM was prompted by a short circuit in a yaw trim actuator connector that occurred during production electrical tests. Subsequent investigations determined that a sharp edge in the backshell damaged the wiring insulation. The NPRM proposed to require replacing certain backshells, as specified in an EASA AD. The FAA is issuing this AD to address an unsafe condition that could result in yaw or pitch trim runaway and VerDate Sep<11>2014 16:01 Jun 23, 2021 Jkt 253001 subsequent loss of control of the helicopter. See EASA AD 2019–0198 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 comments from one commenter; however, none of the comments requested a change to the requirements proposed by the NPRM or the determination of the cost to the public. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed. Related Service Information Under 1 CFR Part 51 EASA AD 2019–0198 specifies replacing backshells part number (P/N) M85049/90–13W02 if manufactured by AMPHENOL or if the manufacturer is unknown (affected part) with backshells P/N M85049/90–13W02 not manufactured by AMPHENOL (serviceable part). EASA AD 2019–0198 also prohibits the (re-)installation of an affected part. 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. Differences Between This AD and the EASA AD EASA AD 2019–0198 applies to all Model MBB–BK117 D–2 helicopters, whereas this AD applies to that model helicopter with an affected part installed instead. EASA AD 2019–0198 requires replacing each affected part with a serviceable part within 9 months, whereas this AD requires that replacement within 30 hours time-inservice instead. Costs of Compliance The FAA estimates that this AD affects 30 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates that operators may incur the following costs in order to comply with this AD. Replacing each backshell takes about 8 work-hours and parts cost $220, for an estimated cost of $900 per backshell. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 33109 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.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0198, dated August 15, 2019 
(EASA AD 2019-0198), to correct an unsafe condition for all Airbus 
Helicopters Deutschland GmbH (AHD), formerly Eurocopter Deutschland 
GmbH, Model MBB-BK117 D-2 helicopters.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to Airbus Helicopters 
Deutschland GmbH Model MBB-BK 117 D-2 helicopters. The NPRM published 
in the Federal Register on April 2, 2021 (86 FR 17322). The NPRM was 
prompted by a short circuit in a yaw trim actuator connector that 
occurred during production electrical tests. Subsequent investigations 
determined that a sharp edge in the backshell damaged the wiring 
insulation. The NPRM proposed to require replacing certain backshells, 
as specified in an EASA AD.
    The FAA is issuing this AD to address an unsafe condition that 
could result in yaw or pitch trim runaway and subsequent loss of 
control of the helicopter. See EASA AD 2019-0198 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 comments from one 
commenter; however, none of the comments requested a change to the 
requirements proposed by the NPRM or the determination of the cost to 
the public.

Conclusion

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

Related Service Information Under 1 CFR Part 51

    EASA AD 2019-0198 specifies replacing backshells part number (P/N) 
M85049/90-13W02 if manufactured by AMPHENOL or if the manufacturer is 
unknown (affected part) with backshells P/N M85049/90-13W02 not 
manufactured by AMPHENOL (serviceable part). EASA AD 2019-0198 also 
prohibits the (re-)installation of an affected part.
    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.

Differences Between This AD and the EASA AD

    EASA AD 2019-0198 applies to all Model MBB-BK117 D-2 helicopters, 
whereas this AD applies to that model helicopter with an affected part 
installed instead. EASA AD 2019-0198 requires replacing each affected 
part with a serviceable part within 9 months, whereas this AD requires 
that replacement within 30 hours time-in-service instead.

Costs of Compliance

    The FAA estimates that this AD affects 30 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates that operators may incur the following 
costs in order to comply with this AD.
    Replacing each backshell takes about 8 work-hours and parts cost 
$220, for an estimated cost of $900 per backshell.

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

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

2021-12-09 Airbus Helicopters Deutschland GmbH (AHD): Amendment 39-
21596; Docket No. FAA-2021-0256; Project Identifier MCAI-2020-00480-
R.

[[Page 33110]]

(a) Effective Date

    This airworthiness directive (AD) is effective July 29, 2021.

(b) Affected Airworthiness Directives

    None.

(c) Applicability

    This AD applies to Airbus Helicopters Deutschland GmbH (AHD) 
Model MBB-BK 117 D-2 helicopters, certificated in any category, 
having an affected part as defined in European Union Aviation Safety 
Agency (EASA) AD 2019-0198, dated August 15, 2019 (EASA AD 2019-
0198).

(d) Subject

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

(e) Reason

    This AD was prompted by a short circuit in a yaw trim actuator 
connector that occurred during production electrical tests. 
Subsequent investigations determined that a sharp edge in the wire 
harness trim connector backshell damaged the wiring insulation. The 
FAA is issuing this AD to address an unsafe condition that could 
result in yaw or pitch trim runaway and subsequent loss of control 
of the helicopter.

(f) Compliance

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

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with EASA AD 2019-0198.

(h) Exceptions to EASA AD 2019-0198

    (1) Where EASA AD 2019-0198 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where paragraph (1) of EASA AD 2019-0198 specifies to 
replace each affected part with a serviceable part within 9 months, 
this AD requires replacing each affected part with a serviceable 
part within 30 hours time-in-service after the effective date of 
this AD.
    (3) Although the service information referenced in EASA AD 2019-
0198 specifies to discard certain parts, this AD requires removing 
those parts from service.
    (4) Where the service information referenced in EASA AD 2019-
0198 specifies to use tooling, equivalent tooling may be used.
    (5) Paragraph (2) of EASA AD 2019-0198 does not apply to this 
AD; this AD requires compliance with paragraph (i) of this AD.
    (6) The ``Remarks'' section of EASA AD 2019-0198 does not apply 
to this AD.

(i) Parts Installation Prohibition

    As of the effective date of this AD, do not install a wire 
harness trim connector backshell identified in paragraph (c) of this 
AD on any helicopter.

 (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,
