Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD No. 2020–0217–E, dated October 6, 2020, to correct an unsafe condition for Airbus Helicopters (AH), formerly Eurocopter, Eurocopter France, Aerospatiale, Model AS 350 B, AS 350 BA, AS 350 B1, AS 350 B2, AS 350 D, AS 355 E, AS 355 F, AS 355 F1, and AS 355 F2 helicopters. EASA advises of a report of an unintended release of the rescue hoist hook on a Model AS 350 B2 helicopter during a ground check. The operator was using the UP/DOWN switches for rescue hoist control, installed on DUNLOP cyclic stick grip part number (P/N) AC66444, when the hoist’s electrically-actuated cable cutter function activated. EASA states that this condition, if not corrected, could lead to further events of inadvertent activation of the rescue hoist cable cutter function and consequent detachment of an external load or person from the PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 helicopter hoist, possibly resulting in personal injury or injury to persons on the ground. To address this potential unsafe condition, Airbus Helicopters published Emergency Alert Service Bulletin (EASB) Nos. 01.00.58 and 01.00.72, each Revision 0 and dated October 1, 2020, to introduce an operational limitation. Accordingly, the EASA AD requires installing a dedicated placard in the cockpit and amending the applicable RFM to prohibit the in-flight use of the UP/DOWN switches for rescue hoist control installed on DUNLOP cyclic stick grip P/N AC66444. EASA states its AD is considered an interim action and further AD action may follow. 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 of the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all information provided by EASA and determining the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. Related Service Information Under 1 CFR Part 51 The FAA has reviewed Airbus Helicopters EASB No. 01.00.58 for Model AS355-series helicopters and Airbus Helicopters EASB No. 01.00.72 for Model AS350-series helicopters, each Revision 0 and dated October 1, 2020, which are co-published as one document. This service information specifies installing a placard and revising the Flight Manual to prohibit the use of the UP/DOWN switches of the DUNLOP cyclic stick grip manufacturer P/N (MP/N) AC66444. 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. AD Requirements This AD requires accomplishing a ground test of the UP/DOWN switches of DUNLOP cyclic stick grip MP/N AC66444 for proper function before each hoist operation. If there is any uncommanded hoist action, this AD requires removing the DUNLOP cyclic stick grip from service. If DUNLOP cyclic stick grip MP/N AC66444 is installed, before the next hoist operation, this AD requires installing a placard and revising the existing RFM for your helicopter to prohibit the use of the UP/DOWN E:\FR\FM\01DER1.SGM 01DER1 Federal Register / Vol. 85, No. 231 / Tuesday, December 1, 2020 / Rules and Regulations switches of the DUNLOP cyclic stick grip. Alternatively, this AD allows removing DUNLOP cyclic stick grip MP/N AC66444, however before the DUNLOP cyclic stick grip is re-installed, this AD requires accomplishing the ground test of the UP/DOWN switches and installing the placard and revising the existing RFM for your helicopter. This AD also prohibits installing an affected DUNLOP cyclic stick grip unless the ground testing of the UP/ DOWN switches has been accomplished, the placard has been installed, and the existing RFM for your helicopter has been revised. Differences Between This AD and the EASA AD The EASA AD applies to all Airbus Helicopters Model AS 350 B, AS 350 BA, AS 350 B1, AS 350 B2, AS 350 D, AS 355 E, AS 355 F, AS 355 F1, and AS 355 F2 helicopters, whereas this AD applies to Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, and AS355F2 helicopters with DUNLOP cyclic stick grip MP/N AC66444 with UP/DOWN switches for rescue hoist control installed instead. This AD requires accomplishing a ground test of the UP/DOWN switches for proper function before each hoist operation, whereas the EASA AD does not. Interim Action The FAA considers this AD to be an interim action. If final action is later identified, the FAA might consider further rulemaking then. khammond on DSKJM1Z7X2PROD with RULES3 Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 390 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. Accomplishing a ground test of the UP/DOWN switches for proper function takes a minimal amount of time for a nominal cost. Installing a placard and revising the existing RFM for your helicopter takes about 0.5 work-hour for an estimated cost of $43 per helicopter and $16,770 for the U.S. fleet. VerDate Sep<11>2014 16:24 Nov 30, 2020 Jkt 253001 Alternatively, replacing the affected DUNLOP cyclic stick grip takes about 2.5 work-hours and parts cost about $2,500 for an estimated cost of $2,713. FAA’s Justification and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (5 U.S.C.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without seeking comment prior to the rulemaking. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because there are required corrective actions that must be completed before the next hoist operation. Therefore, notice and opportunity for prior public comment are impracticable and contrary to public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the reasons stated above, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. 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 AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 76957 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 that this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866, and 2. Will not affect intrastate aviation in Alaska. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of 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 1.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA Emergency AD No. 2020-0217-E, dated 
October 6, 2020, to correct an unsafe condition for Airbus Helicopters 
(AH), formerly Eurocopter, Eurocopter France, Aerospatiale, Model AS 
350 B, AS 350 BA, AS 350 B1, AS 350 B2, AS 350 D, AS 355 E, AS 355 F, 
AS 355 F1, and AS 355 F2 helicopters. EASA advises of a report of an 
unintended release of the rescue hoist hook on a Model AS 350 B2 
helicopter during a ground check. The operator was using the UP/DOWN 
switches for rescue hoist control, installed on DUNLOP cyclic stick 
grip part number (P/N) AC66444, when the hoist's electrically-actuated 
cable cutter function activated. EASA states that this condition, if 
not corrected, could lead to further events of inadvertent activation 
of the rescue hoist cable cutter function and consequent detachment of 
an external load or person from the helicopter hoist, possibly 
resulting in personal injury or injury to persons on the ground.
    To address this potential unsafe condition, Airbus Helicopters 
published Emergency Alert Service Bulletin (EASB) Nos. 01.00.58 and 
01.00.72, each Revision 0 and dated October 1, 2020, to introduce an 
operational limitation.
    Accordingly, the EASA AD requires installing a dedicated placard in 
the cockpit and amending the applicable RFM to prohibit the in-flight 
use of the UP/DOWN switches for rescue hoist control installed on 
DUNLOP cyclic stick grip P/N AC66444. EASA states its AD is considered 
an interim action and further AD action may follow.

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 of the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all information provided by EASA and determining the unsafe 
condition exists and is likely to exist or develop on other helicopters 
of these same type designs.

Related Service Information Under 1 CFR Part 51

    The FAA has reviewed Airbus Helicopters EASB No. 01.00.58 for Model 
AS355-series helicopters and Airbus Helicopters EASB No. 01.00.72 for 
Model AS350-series helicopters, each Revision 0 and dated October 1, 
2020, which are co-published as one document. This service information 
specifies installing a placard and revising the Flight Manual to 
prohibit the use of the UP/DOWN switches of the DUNLOP cyclic stick 
grip manufacturer P/N (MP/N) AC66444.
    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.

AD Requirements

    This AD requires accomplishing a ground test of the UP/DOWN 
switches of DUNLOP cyclic stick grip MP/N AC66444 for proper function 
before each hoist operation. If there is any uncommanded hoist action, 
this AD requires removing the DUNLOP cyclic stick grip from service.
    If DUNLOP cyclic stick grip MP/N AC66444 is installed, before the 
next hoist operation, this AD requires installing a placard and 
revising the existing RFM for your helicopter to prohibit the use of 
the UP/DOWN

[[Page 76957]]

switches of the DUNLOP cyclic stick grip. Alternatively, this AD allows 
removing DUNLOP cyclic stick grip MP/N AC66444, however before the 
DUNLOP cyclic stick grip is re-installed, this AD requires 
accomplishing the ground test of the UP/DOWN switches and installing 
the placard and revising the existing RFM for your helicopter. This AD 
also prohibits installing an affected DUNLOP cyclic stick grip unless 
the ground testing of the UP/DOWN switches has been accomplished, the 
placard has been installed, and the existing RFM for your helicopter 
has been revised.

Differences Between This AD and the EASA AD

    The EASA AD applies to all Airbus Helicopters Model AS 350 B, AS 
350 BA, AS 350 B1, AS 350 B2, AS 350 D, AS 355 E, AS 355 F, AS 355 F1, 
and AS 355 F2 helicopters, whereas this AD applies to Airbus 
Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, 
AS355F, AS355F1, and AS355F2 helicopters with DUNLOP cyclic stick grip 
MP/N AC66444 with UP/DOWN switches for rescue hoist control installed 
instead. This AD requires accomplishing a ground test of the UP/DOWN 
switches for proper function before each hoist operation, whereas the 
EASA AD does not.

Interim Action

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

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because FAA has determined 
that it has good cause to adopt this rule without prior notice and 
comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 390 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.
    Accomplishing a ground test of the UP/DOWN switches for proper 
function takes a minimal amount of time for a nominal cost. Installing 
a placard and revising the existing RFM for your helicopter takes about 
0.5 work-hour for an estimated cost of $43 per helicopter and $16,770 
for the U.S. fleet. Alternatively, replacing the affected DUNLOP cyclic 
stick grip takes about 2.5 work-hours and parts cost about $2,500 for 
an estimated cost of $2,713.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (5 U.S.C.) 
authorizes agencies to dispense with notice and comment procedures for 
rules when the agency, for ``good cause'' finds that those procedures 
are ``impracticable, unnecessary, or contrary to the public interest.'' 
Under this section, an agency, upon finding good cause, may issue a 
final rule without seeking comment prior to the rulemaking.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because there are required corrective actions that must be completed 
before the next hoist operation. Therefore, notice and opportunity for 
prior public comment are impracticable and contrary to public interest 
pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the reasons stated 
above, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) 
for making this amendment effective in less than 30 days.

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 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, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866, and
    2. Will not affect intrastate aviation in Alaska.
