SUPPLEMENTARY INFORMATION: Comments Invited The FAA invites you to participate in this rulemaking by submitting written comments, data, or views. The FAA also invites comments relating to the PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 economic, environmental, energy, or federalism impacts that might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time. The FAA will file in the docket all comments received, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, the FAA will consider all comments received on or before the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The FAA may change this proposal in light of the comments received. Discussion The FAA issued AD 2018–26–02, Amendment 39–19532 (83 FR 66093, December 26, 2018) (‘‘AD 2018–26–02’’) for Airbus Helicopters Model AS350B3 and EC130B4 helicopters with an ARRIEL 2B1 engine with the twochannel Full Authority Digital Engine Control (FADEC) and with new twist grip modification (MOD) 073254 (for Model AS350B3 helicopters) or MOD 073773 (for Model EC130B4 helicopters) installed, and Model AS350B3 and EC130T2 helicopters with an ARRIEL 2D engine installed. AD 2018–26–02 requires repetitively inspecting the wiring, performing an insulation test, inspecting the pilot and copilot throttle twist grip controls, and testing the pilot and copilot throttle twist grip controls for proper functioning. AD 2018–26–02 was prompted by EASA AD No. 2017–0059, dated April 6, 2017 (EASA AD 2017–0059), issued by EASA, which is the Technical Agent for the Member States of the European Union. EASA advised that the switches in the engine ‘‘IDLE’’ or ‘‘FLIGHT’’ control system could be affected by the corrosive effects of a salt-laden atmosphere, which could lead to engine power loss. EASA advised that this condition, if not detected and corrected, could, in case of failure of the other switch, prevent the pilot from switching from ‘‘IDLE’’ to ‘‘FLIGHT’’ mode during training of autorotation landing, making aborting the autorotation impossible, resulting in unintended touchdown. E:\FR\FM\11JNP1.SGM 11JNP1 Federal Register / Vol. 85, No. 113 / Thursday, June 11, 2020 / Proposed Rules Actions Since AD 2018–26–02 Was Issued Since the FAA issued AD 2018–26– 02, the FAA received comments from one commenter. The commenter requested the FAA clarify why the compliance time for the repetitive inspections required in AD 2018–26–02 is given in terms of hours time-inservice (TIS) without also requiring calendar compliance times. The commenter stated that a lot of operators do not operate their aircraft 660 hours TIS in a year and asked whether the FAA is concerned with calendar time. The FAA agrees. Since the unsafe condition involves corrosion, which has a direct relationship between calendar time and airworthiness, it is necessary to add calendar time compliance times for all required actions including the repetitive inspections in this proposed AD. FAA’s Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that an unsafe condition is likely to exist or develop on other helicopters of the same type design. jbell on DSKJLSW7X2PROD with PROPOSALS Related Service Information Under 1 CFR Part 51 The FAA reviewed one document that co-publishes three Airbus Helicopters Emergency Alert Service Bulletin (EASB) identification numbers: No. 05.00.61, Revision 3, dated June 15, 2015, for Model AS350B3 helicopters; No. 05.00.41, Revision 2, dated June 15, 2015, for the non-FAA type certificated Model AS550C3 helicopter; and No. 05A009, Revision 3, dated June 15, 2015, for Model EC130B4 helicopters. EASB Nos. 05.00.61 and 05A009 are incorporated by reference in AD 2018– 26–02 and are retained for the requirements of this AD. EASB No. 05.00.41 is not incorporated by reference in AD 2018–26–02 and is not incorporated by reference in this AD. This service information applies to helicopters with an ARRIEL 2B1 engine installed and describes procedures for a functional check and installation of protection for micro-contacts (microswitches) 53Ka, 53Kb, and 65K (IDLE/FLIGHT mode). The FAA also reviewed one document that co-publishes three Airbus Helicopters EASB identification VerDate Sep<11>2014 16:51 Jun 10, 2020 Jkt 250001 numbers: No. 05.00.77, Revision 1, dated June 15, 2015, for Model AS350B3 helicopters; No. 05.00.52, Revision 1, dated June 15, 2015, for the non-FAA type certificated Model AS550C3 helicopter; and No. 05A014, Revision 1, dated June 15, 2015, for Model EC130T2 helicopters. EASB Nos. 05.00.77 and 05A014 are incorporated by reference in AD 2018–26–02 and are retained for the requirements of this AD. EASB No. 05.00.52 is not incorporated by reference in this AD. This service information applies to helicopters with an ARRIEL 2D engine installed and describes procedures for a check of the protection for micro-contacts (microswitches) 53Ka, 53Kb, and 65K (IDLE/FLIGHT mode). This service information 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. Proposed AD Requirements This proposed AD would retain the inspection requirements of AD 2018– 26–02 and would include, before the next practice autorotation, within 100 hours TIS, or 6 months, whichever occurs first, inspecting the wiring, performing an insulation test, inspecting the pilot and copilot throttle twist grip controls, and testing the pilot and copilot throttle twist grip controls for proper functioning. This AD would also include calendar time requirements for the repetitive inspections to be completed at intervals not to exceed 330 hours TIS or 6 months, whichever occurs first, and at intervals not to exceed 660 hours TIS or 12 months, whichever occurs first, depending on operating conditions. 35605 Costs of Compliance The FAA estimates that this proposed AD would affect 617 helicopters of U.S. Registry. The FAA estimates that operators may incur the following costs in order to comply with this proposed AD. Labor costs are estimated at $85 per work-hour. Inspecting the wiring, performing an insulation test, inspecting the pilot and copilot throttle twist grip controls, and testing the pilot and copilot throttle twist grip controls would take about 4 work-hours, for a total estimated cost of $340 per helicopter and $209,780 for the U.S. fleet per inspection cycle. 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. Interim 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, 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 FAA considers this proposed AD to be an interim action. If final action is later identified, the FAA might consider further rulemaking then. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Differences Between This Proposed AD and the EASA AD The EASA AD requires the initial inspections within 10 flight hours or 7 days; this proposed AD requires compliance before the next autorotation training flight, 100 hours TIS, or 6 months, whichever occurs earlier, as the unsafe condition only occurs when transitioning the throttle in-flight from flight to idle and back to flight, such as during a practice autorotation. Additionally, the EASA AD requires installing Airbus Helicopters MOD 074263; this proposed AD does not as it does not correct the unsafe condition.

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 removing Airworthiness Directive (AD) 2018–26–02, Amendment 39–19532 (83 FR 66093, December 26, 2018), and adding the following new AD: ■ Airbus Helicopters: Docket No. FAA–2020– 0570; Product Identifier 2019–SW–121– AD. (a) Applicability This AD applies to the following Airbus Helicopters helicopters, certificated in any category: (1) Model AS350B3 helicopters with an ARRIEL 2B1 engine with the two-channel Full Authority Digital Engine Control (FADEC) and with new twist grip modification (MOD) 073254 or with an ARRIEL 2D engine installed; (2) Model EC130B4 helicopters with an ARRIEL 2B1 engine with the two-channel FADEC and with new twist grip MOD 073773 installed; and (3) Model EC130T2 helicopters with an ARRIEL 2D engine installed. (b) Unsafe Condition This AD defines the unsafe condition as failure of one of the two contactors, 53Ka or 53Kb, which can prevent switching from ‘‘IDLE’’ mode to ‘‘FLIGHT’’ mode during autorotation training making it impossible to recover from a practice autorotation and compelling the pilot to continue the autorotation to the ground. This condition could result in unintended touchdown to the ground at a flight-idle power setting during a practice autorotation, damage to the helicopter, and injury to occupants. (c) Affected ADs This AD replaces AD 2018–26–02, Amendment 39–19532 (83 FR 66093, December 26, 2018). jbell on DSKJLSW7X2PROD with PROPOSALS (d) Comments Due Date The FAA must receive comments by July 27, 2020.

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2018-26-02 for Airbus Helicopters (previously Eurocopter France) Model 
AS350B3, EC130B4, and EC130T2 helicopters. AD 2018-26-02 requires 
inspecting the pilot's and co-pilot's throttle twist for proper 
operation. Since the FAA issued AD 2018-26-02, the FAA received a 
public comment that prompted additional review. This proposed AD would 
retain the requirements of AD 2018-26-02 and add calendar time 
compliance times for the required actions. The actions of this proposed 
AD are intended to address an unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by July 27, 
2020.

Discussion

    The FAA issued AD 2018-26-02, Amendment 39-19532 (83 FR 66093, 
December 26, 2018) (``AD 2018-26-02'') for Airbus Helicopters Model 
AS350B3 and EC130B4 helicopters with an ARRIEL 2B1 engine with the two-
channel Full Authority Digital Engine Control (FADEC) and with new 
twist grip modification (MOD) 073254 (for Model AS350B3 helicopters) or 
MOD 073773 (for Model EC130B4 helicopters) installed, and Model AS350B3 
and EC130T2 helicopters with an ARRIEL 2D engine installed. AD 2018-26-
02 requires repetitively inspecting the wiring, performing an 
insulation test, inspecting the pilot and copilot throttle twist grip 
controls, and testing the pilot and copilot throttle twist grip 
controls for proper functioning.
    AD 2018-26-02 was prompted by EASA AD No. 2017-0059, dated April 6, 
2017 (EASA AD 2017-0059), issued by EASA, which is the Technical Agent 
for the Member States of the European Union. EASA advised that the 
switches in the engine ``IDLE'' or ``FLIGHT'' control system could be 
affected by the corrosive effects of a salt-laden atmosphere, which 
could lead to engine power loss. EASA advised that this condition, if 
not detected and corrected, could, in case of failure of the other 
switch, prevent the pilot from switching from ``IDLE'' to ``FLIGHT'' 
mode during training of autorotation landing, making aborting the 
autorotation impossible, resulting in unintended touchdown.

[[Page 35605]]

Actions Since AD 2018-26-02 Was Issued

    Since the FAA issued AD 2018-26-02, the FAA received comments from 
one commenter. The commenter requested the FAA clarify why the 
compliance time for the repetitive inspections required in AD 2018-26-
02 is given in terms of hours time-in-service (TIS) without also 
requiring calendar compliance times. The commenter stated that a lot of 
operators do not operate their aircraft 660 hours TIS in a year and 
asked whether the FAA is concerned with calendar time. The FAA agrees. 
Since the unsafe condition involves corrosion, which has a direct 
relationship between calendar time and airworthiness, it is necessary 
to add calendar time compliance times for all required actions 
including the repetitive inspections in this proposed AD.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA about the 
unsafe condition described in its AD. The FAA is proposing this AD 
after evaluating all known relevant information and determining that an 
unsafe condition is likely to exist or develop on other helicopters of 
the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed one document that co-publishes three Airbus 
Helicopters Emergency Alert Service Bulletin (EASB) identification 
numbers: No. 05.00.61, Revision 3, dated June 15, 2015, for Model 
AS350B3 helicopters; No. 05.00.41, Revision 2, dated June 15, 2015, for 
the non-FAA type certificated Model AS550C3 helicopter; and No. 05A009, 
Revision 3, dated June 15, 2015, for Model EC130B4 helicopters. EASB 
Nos. 05.00.61 and 05A009 are incorporated by reference in AD 2018-26-02 
and are retained for the requirements of this AD. EASB No. 05.00.41 is 
not incorporated by reference in AD 2018-26-02 and is not incorporated 
by reference in this AD. This service information applies to 
helicopters with an ARRIEL 2B1 engine installed and describes 
procedures for a functional check and installation of protection for 
micro-contacts (microswitches) 53Ka, 53Kb, and 65K (IDLE/FLIGHT mode).
    The FAA also reviewed one document that co-publishes three Airbus 
Helicopters EASB identification numbers: No. 05.00.77, Revision 1, 
dated June 15, 2015, for Model AS350B3 helicopters; No. 05.00.52, 
Revision 1, dated June 15, 2015, for the non-FAA type certificated 
Model AS550C3 helicopter; and No. 05A014, Revision 1, dated June 15, 
2015, for Model EC130T2 helicopters. EASB Nos. 05.00.77 and 05A014 are 
incorporated by reference in AD 2018-26-02 and are retained for the 
requirements of this AD. EASB No. 05.00.52 is not incorporated by 
reference in this AD. This service information applies to helicopters 
with an ARRIEL 2D engine installed and describes procedures for a check 
of the protection for micro-contacts (microswitches) 53Ka, 53Kb, and 
65K (IDLE/FLIGHT mode).
    This service information 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.

Proposed AD Requirements

    This proposed AD would retain the inspection requirements of AD 
2018-26-02 and would include, before the next practice autorotation, 
within 100 hours TIS, or 6 months, whichever occurs first, inspecting 
the wiring, performing an insulation test, inspecting the pilot and 
copilot throttle twist grip controls, and testing the pilot and copilot 
throttle twist grip controls for proper functioning. This AD would also 
include calendar time requirements for the repetitive inspections to be 
completed at intervals not to exceed 330 hours TIS or 6 months, 
whichever occurs first, and at intervals not to exceed 660 hours TIS or 
12 months, whichever occurs first, depending on operating conditions.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires the initial inspections within 10 flight hours 
or 7 days; this proposed AD requires compliance before the next 
autorotation training flight, 100 hours TIS, or 6 months, whichever 
occurs earlier, as the unsafe condition only occurs when transitioning 
the throttle in-flight from flight to idle and back to flight, such as 
during a practice autorotation.
    Additionally, the EASA AD requires installing Airbus Helicopters 
MOD 074263; this proposed AD does not as it does not correct the unsafe 
condition.

Interim Action

    The FAA considers this proposed AD to be an interim action. If 
final action is later identified, the FAA might consider further 
rulemaking then.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 617 
helicopters of U.S. Registry. The FAA estimates that operators may 
incur the following costs in order to comply with this proposed AD. 
Labor costs are estimated at $85 per work-hour.
    Inspecting the wiring, performing an insulation test, inspecting 
the pilot and copilot throttle twist grip controls, and testing the 
pilot and copilot throttle twist grip controls would take about 4 work-
hours, for a total estimated cost of $340 per helicopter and $209,780 
for the U.S. fleet per inspection cycle.

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, 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 removing Airworthiness Directive (AD) 
2018-26-02, Amendment 39-19532 (83 FR 66093, December 26, 2018), and 
adding the following new AD:

Airbus Helicopters: Docket No. FAA-2020-0570; Product Identifier 
2019-SW-121-AD.

(a) Applicability

    This AD applies to the following Airbus Helicopters helicopters, 
certificated in any category:
    (1) Model AS350B3 helicopters with an ARRIEL 2B1 engine with the 
two-channel Full Authority Digital Engine Control (FADEC) and with 
new twist grip modification (MOD) 073254 or with an ARRIEL 2D engine 
installed;
    (2) Model EC130B4 helicopters with an ARRIEL 2B1 engine with the 
two-channel FADEC and with new twist grip MOD 073773 installed; and
    (3) Model EC130T2 helicopters with an ARRIEL 2D engine 
installed.

(b) Unsafe Condition

    This AD defines the unsafe condition as failure of one of the 
two contactors, 53Ka or 53Kb, which can prevent switching from 
``IDLE'' mode to ``FLIGHT'' mode during autorotation training making 
it impossible to recover from a practice autorotation and compelling 
the pilot to continue the autorotation to the ground. This condition 
could result in unintended touchdown to the ground at a flight-idle 
power setting during a practice autorotation, damage to the 
helicopter, and injury to occupants.

(c) Affected ADs

    This AD replaces AD 2018-26-02, Amendment 39-19532 (83 FR 66093, 
December 26, 2018).

(d) Comments Due Date

    The FAA must receive comments by July 27, 2020.

(e) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(f) Required Actions

    (1) Before the next practice autorotation, within 100 hours 
time-in-service (TIS), or 6 months, whichever occurs first, inspect 
the wiring, perform an insulation test, inspect the pilot and 
copilot throttle twist grip controls, and test the pilot and copilot 
throttle twist grip controls for proper functioning by following the 
Accomplishment Instructions, paragraph 3.B.1 through 3.B.6, of 
Airbus Helicopters Emergency Alert Service Bulletin (EASB) No. 
05.00.61, Revision 3, dated June 15, 2015, for Model AS350B3 
helicopters with an ARRIEL 2B1 engine; EASB No. 05.00.77, Revision 
1, dated June 15, 2015, for Model AS350B3 helicopters with an ARRIEL 
2D engine; EASB No. 05A009, Revision 3, dated June 15, 2015, for 
Model EC130B4 helicopters; or EASB No. 05A014, Revision 1, dated 
June 15, 2015, for Model EC130T2 helicopters, as appropriate for 
your model helicopter.
    (2) Repeat the inspections in paragraph (f)(1) of this AD at 
intervals not to exceed the following compliance times. For purposes 
of this AD, salt laden conditions exist when a helicopter performs a 
flight from a takeoff and landing area, heliport, or airport less 
than 0.5 statute mile from salt water or performs a flight within 
0.5 statute mile from salt water below an altitude of 1,000 ft. 
above ground or sea level.
    (i) For helicopters that have operated in salt laden conditions 
since the previous inspection required by this AD, at intervals not 
to exceed 330 hours TIS or 6 months, whichever occurs first.
    (ii) For helicopters that have not operated in salt laden 
conditions since the previous inspection required by this AD, at 
intervals not to exceed 660 hours TIS or 12 months, whichever occurs 
first.

(g) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Rotorcraft Standards Branch, FAA, may approve 
AMOCs for this AD. Send your proposal to: George Schwab, Aviation 
Safety Engineer, Safety Management Section, Rotorcraft Standards 
Branch, FAA, 10101 Hillwood Parkway, Fort Worth, Texas 76177; 
telephone 817-222-5110; email [email protected].
    (2) For operations conducted under a 14 CFR part 119 operating 
certificate or under 14 CFR part 91, subpart K, the FAA suggests 
that you notify your principal inspector, or lacking a principal 
inspector, the manager of the local flight standards district office 
or certificate holding district office before operating any aircraft 
complying with this AD through an AMOC.
