credit.17 Nevertheless, FHFA will 

consult with and refer matters to the 

Attorney General and coordinate with 

the Department of Justice on 

enforcement of fair lending matters as 

appropriate. 

FHFA will consider whether the 

regulated entity has conducted any selfevaluations or undertaken any 

corrective actions when making 

supervisory and enforcement decisions. 

FHFA will view responsible business 

practices such as self-testing, 

implementation of management 

controls, and voluntary remedial action 

favorably when making fair lending 

supervisory and enforcement 

determinations. In particular, FHFA 

commits to taking into consideration an 

entity’s cooperation and candor during 

examinations and monitoring. Regulated 

entities are not required to self-report 

potential violations of fair lending laws. 

However, self-reporting of violations of 

fair lending laws will be viewed 

favorably by FHFA as it exercises its 

discretion. FHFA also considers the 

number and duration of violations 

identified, the nature of the evidence of 

discrimination (i.e., overt 

discrimination, disparate treatment, or 

disparate impact), the pervasiveness of 

the discrimination, the presence and 

effectiveness of any anti-discrimination 

policies, any history of discriminatory 

conduct, any corrective measures 

implemented or proposed by the 

regulated entity, and any other factors 

for determining the appropriateness of 

any potential action. 

Consideration of Differences Between 

the Banks and the Enterprises 

FHFA recognizes the important 

distinctions between the two types of 

regulated entities, the Enterprises and 

the Banks. In drafting this Policy 

Statement, FHFA has considered the 

differences between the Enterprises and 

the Banks with respect to the Banks’ 

cooperative ownership structure, 

mission of providing liquidity to 

members, affordable housing and 

community development mission, 

capital structure, and joint and several 

liability, as well as other applicable 

differences.18

SUPPLEMENTARY INFORMATION: 

Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2021–0040, dated January 27, 2021 

(EASA AD 2021–0040) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Leonardo S.p.a. Model 

AW119 MKII helicopters. 

This AD was prompted by reports of 

detected smoke and burning smell 

during flight, caused by chafing of 

electrical wiring. The FAA is issuing 

this AD to address detected smoke, 

burning smell during flight, and chafing 

of electrical wiring, which could lead to 

further occurrences of smoke in the 

cabin, or loss of function of avionics 

equipment, and possibly result in 

reduced control of the helicopter. See 

the MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0040 specifies 

procedures for an inspection of the 

instrument panel electrical wiring for 

defects (including wire chafing; 

pinched, broken, or severely bent wires; 

deteriorated, cracked or missing wire 

shielding or insulation; and loose, 

corroded, or broken wire connectors), 

corrective actions (repair or replacement 

of the wiring and a pin to pin continuity 


jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 86, No. 129 / Friday, July 9, 2021 / Rules and Regulations 36203 

check on the repaired wiring) if 

necessary, a modification of the wiring 

installation, and, for certain helicopters, 

an additional modification of the wiring 

installation. 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 

This product has been approved by 

the aviation authority of another 

country, and is 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– 

0040, 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 (CAAs) to 

use this process. As a result, EASA AD 

2021–0040 is incorporated by reference 

in the FAA final rule. This AD will, 

therefore, require compliance with 

EASA AD 2021–0040 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 2021–0040 that is required for 

compliance with EASA AD 2021–0040 

is available on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0542. 

FAA’s Justification 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 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. 

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 foregoing notice 

and comment prior to adoption of this 

rule because of detected smoke, burning 

smell during flight, and chafing of 

electrical wiring, which could lead to 

further occurrences of smoke in the 

cabin, or loss of function of avionics 

equipment, and possibly result in 

reduced control of the helicopter. In 

addition, the compliance time for the 

inspection of the instrument panel 

electrical wiring is within 25 hours 

time-in-service or 3 months, whichever 

occurs first after the effective date of 

this AD, which is shorter than the time 

necessary for the public to comment and 

for publication of the final rule. 

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, 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, for the same reasons the FAA 

found good cause to forego notice and 

comment. 

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– 

2021–0542; Project Identifier MCAI– 

2021–00117–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 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 notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 10 helicopters of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 


jbell on DSKJLSW7X2PROD with RULES
36204 Federal Register / Vol. 86, No. 129 / Friday, July 9, 2021 / Rules and Regulations 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Up to 11 work-hours × $85 per hour = $935 ................................................................... $73 Up to $1,008 ....... Up to $10,080. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition actions specified in 

this AD. 

According to the manufacturer, some 

or all of the costs of this AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. The FAA does not control 

warranty coverage for affected 

individuals. As a result, the FAA has 

included all known costs in the cost 

estimate. 

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 

would not have federalism implications 

under Executive Order 13132. This 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 regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Safran Helicopter 

Engines Arriel 2B, 2B1, 2C, 2C1, 2C2, 

2S1 and 2S2 model turboshaft engines. 

The NPRM published in the Federal 

Register on February 22, 2021 (86 FR 

10501). The NPRM was prompted by 

reports of non-conforming fuel filter 

pre-blockage pressure switches. In the 

NPRM, the FAA proposed to require 

repetitive visual inspections of the fuel 

filter by-pass indicator pop-up, a onetime operational test of the fuel filter 

pre-blockage pressure switch and, 

depending on the findings, replacement 

of the fuel filter pre-blockage pressure 

switch with a part eligible for 

installation. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

The European Union Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Community, has issued EASA 

AD 2019–0180, dated July 25, 2019 

(referred to after this as ‘‘the MCAI’’), to 

address the unsafe condition on these 

products. The MCAI states: 

Occurrences have been reported of nonconforming fuel filter pre-blockage pressure 

switches, manufactured before December 

2016. The non-conformity of the fuel filter 

pre-blockage pressure switch can cause its 

non-activation in case of fuel system 

contamination, with consequent opening of 

the by-pass without indication in the cockpit. 

This condition, if not detected and 

corrected, and in case of fuel contamination, 

could lead to an uncommanded in-flight 

shut-down, possibly resulting in an 

emergency autorotation landing on a single 

engine helicopter, or to a double 

uncommanded in-flight shut-down on a twin 

engine helicopter. 

To address this potential unsafe condition, 

SAFRAN issued the MSB, providing 

inspection instructions. 

For the reasons described above, this 

[EASA AD] requires repetitive daily visual 

checks of the fuel filter by-pass indicator 

pop-up. This [EASA] AD also requires a oneVerDate Sep<11>2014 15:58 Jul 08, 2021 Jkt 253001 PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 E:\FR\FM\09JYR1.SGM 09JYR1
