Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Helicopters Model AS350B, 

AS350B2, AS350B3, and AS350BA 

helicopters. This AD was prompted by 

a report that a modification of the 

electrical wiring of the hydraulic system 

was wrongly embodied on certain 

helicopters, and a wiring nonconformity caused the solenoid of the 

tail rotor (TR) load compensator to deenergize when the ‘‘HYD’’ cut-off switch 

was activated. This AD requires 

installing a placard in the cockpit, in 

full view of the pilots; a functional 

check of the main rotor (MR) and TR 

servo actuator solenoids, and corrective 

actions (modification) if necessary; a 

modification (unless already done); and, 

after corrective actions or modification, 

optional removal of the placard, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

incorporated by reference. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD becomes effective 

February 25, 2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of February 25, 2022. 

The FAA must receive comments on 

this AD by March 28, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA 

Emergency AD 2021–0123–E, dated May 

7, 2021 (EASA AD 2021–0123–E) (also 

referred to as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Airbus Helicopters Model 

AS350B, AS350B2, AS350B3, and 

AS350BA helicopters. 

This AD was prompted by a report 

that a modification of the electrical 

wiring of the hydraulic system was 

wrongly embodied on certain 

helicopters, and a wiring nonconformity caused the solenoid of the 

TR load compensator to de-energize 

when the ‘‘HYD’’ cut-off switch was 

activated. The FAA is issuing this AD to 

address the unsafe condition, which if 

not corrected, could lead to loss of 

hydraulic power in TR control during 

application of the emergency procedure 

for loss of MR hydraulic, or during 

hydraulic off training when the ‘‘HYD’’ 

cut-off switch is activated, possibly 

resulting in loss of control of the 

helicopter. See the MCAI for additional 

background information. 

Related IBR Material Under 1 CFR Part 

51 

EASA AD 2021–0123–E specifies 

procedures for installing a placard in 

the cockpit, in full view of the pilots; a 

functional check of the MR and TR 

servo actuator solenoids, and corrective 

actions (modification) if necessary; a 

modification (unless already done); and, 

after corrective actions or modification, 

optional removal of the placard. 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 

These products have been approved 

by the aviation authority of another 

country, and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is issuing this AD after 

evaluating all pertinent information and 

determining that the unsafe condition 

exists and is likely to exist or develop 

on other products of the same type 

design. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2021– 

0123–E, described previously, as 

incorporated by reference, except for 

any differences identified as exceptions 

in the regulatory text of this 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 to use this 

process. As a result, EASA AD 2021– 

0123–E will be incorporated by 

reference in the FAA final rule. This AD 

would, therefore, require compliance 

with EASA AD 2021–0123–E in its 

entirety, through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

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 

2021–0123–E that is required for 

compliance with EASA AD 2021–0123– 

E is available on the internet at https:// 

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

1181. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) 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 providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

There are currently no domestic 

operators of these products. 

Accordingly, notice and opportunity for 

prior public comment are unnecessary, 

pursuant to 5 U.S.C. 553(b)(3)(B). In 

addition, for the foregoing reasons, 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. 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this AD. Send your 

comments to an address listed under 

ADDRESSES. Include ‘‘Docket No. FAA– 

2021–1181; Project Identifier MCAI– 

2021–00562–R’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the AD, 

explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this AD because of 

those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this AD. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to Darren Gassetto, 

Aerospace Engineer, COS Program 

Management Section, Operational 

Safety Branch, Compliance & 

Airworthiness Division, FAA, 1600 

Stewart Ave., Suite 410, Westbury, NY 

11590; phone: (516) 228–7323; email: 

Darren.Gassetto@faa.gov. Any 

commentary that the FAA receives that 

is not specifically designated as CBI will 

be placed in the public docket for this 

rulemaking.

Federal Register / Vol. 87, No. 28 / Thursday, February 10, 2022 / Rules and Regulations 7697 

Regulatory Flexibility Act (RFA) 

The requirements of the 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 the 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 

Currently, there are no affected U.S.- 

registered helicopters. If an affected 

helicopter is imported and placed on 

the U.S. Register in the future, the FAA 

provides the following cost estimates to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Install Placard .................................. 1 work-hour × $85 per hour = $85 ............................................................ $0 $85 

Functional Check ............................. 1 work-hour × $85 per hour = $85 ............................................................ 0 85 

Modification ...................................... 2 work-hours × $85 per hour = $170 ........................................................ 500 670 

The FAA estimates the following 

costs to do any necessary on-condition 

action that would be required based on 

the results of any required inspections. 

The FAA has no way of determining the 

number of helicopters that might need 

this on-condition action: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Modification ...................................... 2 work-hours × $85 per hour = $170 ........................................................ $500 $670 

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 above, I 

certify this regulation: 

(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

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: 

2022–02–04 Airbus Helicopters: 

Amendment 39–21901; Docket No. 

FAA–2021–1181; Project Identifier 

MCAI–2021–00562–R. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective February 25, 2022. 

(b) Affected ADs 

None. 

(c) Applicability

hydraulic system was wrongly embodied on 

certain helicopters, and a wiring nonconformity caused the solenoid of the tail 

rotor (TR) load compensator to de-energize 

when the ‘‘HYD’’ cut-off switch was 

activated. The FAA is issuing this AD to 

address the unsafe condition, which if not 

corrected, could lead to loss of hydraulic 

power in TR control during application of the 

emergency procedure for loss of main rotor 

(MR) hydraulic, or during hydraulic off 

training when the ‘‘HYD’’ cut-off switch is 

activated, possibly resulting in loss of control 

of the helicopter.

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Leonardo S.p.a. Model AB412 and
