Discussion The 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. This proposed 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 backshell damaged the wiring insulation. The FAA is issuing this proposed AD to address an unsafe condition that could result in yaw or pitch trim runaway and subsequent loss of control of the helicopter. See the E:\FR\FM\02APP1.SGM 02APP1 Federal Register / Vol. 86, No. 62 / Friday, April 2, 2021 / Proposed Rules EASA AD for additional background information. 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. FAA’s Determination and Requirements of This Proposed AD These products have been approved by the aviation authority of another country, and are 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 EASA AD referenced above. The FAA is proposing this AD after evaluating all the relevant information and determining the unsafe condition described previously is likely to exist or develop in other products of the same type design. jbell on DSKJLSW7X2PROD with PROPOSALS Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2019–0198, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under ‘‘Differences Between this Proposed AD and the EASA 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 2019–0198 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2019–0198 in its entirety, through that incorporation, except for any differences VerDate Sep<11>2014 16:28 Apr 01, 2021 Jkt 253001 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 2019–0198 that is required for compliance with EASA AD 2019–0198 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0256 after the FAA final rule is published. Differences Between This Proposed AD and the EASA AD The EASA AD applies to all Model MBB–BK117 D–2 helicopters, whereas this proposed AD applies to that model helicopter with an affected part installed instead. The EASA AD requires replacing each affected part with a serviceable part within 9 months, whereas this proposed AD would require that replacement within 30 hours time-in-service instead. Costs of Compliance The FAA estimates that this proposed 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 proposed AD. Replacing each backshell would take about 8 work-hours and parts would 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 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 17323 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 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Airbus Helicopters Deutschland GmbH (AHD): Docket No. FAA–2021–0256; Project Identifier MCAI–2020–00480–R.

Discussion

    The 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.
    This proposed 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 backshell 
damaged the wiring insulation. The FAA is issuing this proposed AD to 
address an unsafe condition that could result in yaw or pitch trim 
runaway and subsequent loss of control of the helicopter. See the

[[Page 17323]]

EASA AD for additional background information.

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.

FAA's Determination and Requirements of This Proposed AD

    These products have been approved by the aviation authority of 
another country, and are 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 EASA 
AD referenced above. The FAA is proposing this AD after evaluating all 
the relevant information and determining 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 2019-0198, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD and except as discussed under 
``Differences Between this Proposed AD and the EASA 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 2019-0198 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2019-0198 in its 
entirety, through that incorporation, except for any differences 
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 2019-0198 that is required for compliance with EASA AD 2019-
0198 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2021-0256 after the FAA 
final rule is published.

Differences Between This Proposed AD and the EASA AD

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

Costs of Compliance

    The FAA estimates that this proposed 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 proposed AD.
    Replacing each backshell would take about 8 work-hours and parts 
would 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

    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.

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

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:

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

(a) Comments Due Date

    The FAA must receive comments by May 17, 2021.

(b) Affected Airworthiness Directives (ADs)

    None.

(c) Applicability

    This AD applies to Airbus Helicopters Deutschland GmbH 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).

[[Page 17324]]

(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, Strategic Policy Rotorcraft Section, FAA, has 
the authority to approve AMOCs for this AD, if requested using the
