SUPPLEMENTARY INFORMATION: 


jspears on DSK121TN23PROD with RULES1
Federal Register / Vol. 87, No. 28 / Thursday, February 10, 2022 / Rules and Regulations 7699 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0126, 

dated May 10, 2021 (EASA AD 2021– 

0126) to correct an unsafe condition for 

all serial-numbered Leonardo S.p.a. 

(AgustaWestland S.p.A., formerly 

Agusta S.p.A., Agusta un’azienda di 

Finmeccanica S.p.A., Costruzioni 

Aeronautiche Giovanni Agusta) Model 

AB212, AB412, and AB412EP 

helicopters. 

EASA AD 2021–0126 was prompted 

by a report that due to the application 

of an incorrect torque level during the 

assembly process, certain oil and fuel 

check valves are susceptible to cracking, 

which may lead to fuel or oil leakage. 

The FAA is issuing this AD to detect 

cracks and prevent a lack of engine 

lubrication, fuel or oil leakage, and loss 

of fuel supply to the engine, possibly 

resulting in an engine in-flight shutdown or fire and subsequent loss of 

control of the helicopter. See EASA AD 

2021–0126 for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0126 specifies 

procedures for identification and 

inspection of the oil check valve part 

number (P/N) 209–062–520–1 and fuel 

check valve P/N 209–062–607–1, 

manufactured by Circor Aerospace 

which exceed certain dimensions, 

except those which have had the correct 

torque level applied. For certain 

helicopters, EASA AD 2021–0126 

specifies procedures for visually 

inspecting the oil and fuel check valves 

for fuel leaks and cracks at intervals not 

to exceed 25 flight hours or 3 months, 

whichever occurs first, and depending 

on the inspection results, replacing the 

affected parts with serviceable parts. For 

certain helicopters EASA AD 2021–0126 

also requires replacing each affected 

part with a serviceable part, which is 

considered a terminating action for the 

recurring inspections. The ‘‘Reason’’ 

section of EASA AD 2021–0126 requires 

removing certain parts from service. 

Although the ‘‘Required Action(s) and 

Compliance Time(s)’’ section of EASA 

AD 2021–0126 does not specifically 

state that affected parts should be 

removed from service, for clarification, 

EASA AD 2021–0126 requires the 

removal from service of the affected 

parts as defined in EASA AD 2021– 

0126. EASA AD 2021–0126 also 

prohibits installing an affected part on 

any helicopter. 

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. 

Other Related Service Information 

The FAA reviewed Leonardo 

Helicopters Alert Service Bulletin No. 

412–166, dated March 30, 2021, which 

specifies procedures to identify and 

inspect the fuel check valve P/N 209– 

062–607–1. The FAA also reviewed 

Leonardo Helicopters Alert Service 

Bulletin No. 412–167, dated March 30, 

2021, which specifies procedures to 

identify and inspect the oil check valve 

P/N 209–062–520–1. 

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 EASA AD 2021–0126 

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 

these same type designs. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2021– 

0126, described previously, as 

incorporated by reference, except for 

any differences identified as exceptions 

in the regulatory text of this AD and 

except as discussed under ‘‘Differences 

Between this AD and EASA AD 2021– 

0126.’’ 

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– 

0126 is incorporated by reference in this 

AD. This AD, therefore, requires 

compliance with EASA AD 2021–0126 

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 2021–0126 that is required for 

compliance with EASA AD 2021–0126 

is available on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

1184. 

Differences Between This AD and EASA 

AD 2021–0126 

EASA AD 2021–0126 applies to all 

serial-numbered Model AB212, AB412 

and AB412EP helicopters, whereas this 

AD only applies to Model AB412 and 

AB412 EP helicopters. This AD does not 

apply to Model AB212 helicopters 

because that model is not FAA typecertificated. Service information 

referenced in EASA AD 2021–0126 

specifies sending compliance forms to 

the manufacturer; this AD does not. 

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– 

2021–1184; Project Identifier MCAI– 

2021–00573–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 


jspears on DSK121TN23PROD with RULES1
7700 Federal Register / Vol. 87, No. 28 / Thursday, February 10, 2022 / Rules and Regulations 

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 Hal Jensen, Aerospace 

Engineer, Operational Safety Branch, 

Compliance & Airworthiness Division, 

FAA, 950 L’Enfant Plaza N SW, 

Washington, DC 20024; telephone (202) 

267–9167; email hal.jensen@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. 

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 

There are no costs of compliance with 

this AD because there are no helicopters 

with these type certificates on the U.S. 

Registry. 

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.

bellcrank-K to determine if it is 

correctly installed and has a correct 

position marking and, depending on the 

findings, applicable corrective actions, 

as specified in a European Union 

Aviation Safety Agency (EASA) AD, 

which is incorporated by reference. This 

AD also allows installation of an 

affected collective bellcrank-K, provided 

certain instructions are followed. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective March 17, 

2022.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0074, 

dated March 15, 2021 (EASA AD 2021– 

0074), to correct an unsafe condition for 

all Airbus Helicopters Deutschland 

GmbH (AHD) (formerly Eurocopter 

Deutschland GmbH; and Airbus 

Helicopters Inc., formerly American 

Eurocopter LLC) Model MBB–BK117 C– 

2 and 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 all Airbus Helicopters 

Deutschland GmbH Model MBB–BK 117 

C–2 and MBB–BK 117 D–2 helicopters. 

The NPRM published in the Federal 

Register on November 26, 2021 (86 FR 

67364). The NPRM was prompted by a 

report that a collective bellcrank-K 

(affected part) was found incorrectly 

installed on a helicopter. Subsequent 

investigations revealed that the affected 

part was an in-service replacement, and 

that the position marking on that part 

was incorrect. The NPRM proposed to 

require inspecting the collective 

bellcrank-K to determine if it is 

correctly installed and has a correct 

position marking and, depending on the 

findings, applicable corrective actions, 

as specified in EASA AD 2021–0074. 

The NPRM also proposed to allow 

installation of an affected collective 

bellcrank-K, provided certain 

instructions are followed. 

The FAA is issuing this AD to address 

incorrect installation of a collective 

bellcrank-K, which could lead to 

unwanted collective input, resulting in 

reduced control of the helicopter. See 

EASA AD 2021–0074 for additional 

background information.
