Federal Register / Vol. 86, No. 129 / Friday, July 9, 2021 / Rules and Regulations 36207 

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. 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 adding 

the following new airworthiness 

directive: 

2021–13–03 Safran Helicopter Engines, 

S.A. (Type Certificate previously held by 

Turbomeca, S.A.): Amendment 39– 

21608; Docket No. FAA–2020–1180; 

Project Identifier MCAI–2020–00517–E. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective August 13, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Safran Helicopter 

Engines, S.A. (Type Certificate previously 

held by Turbomeca, S.A.) Arriel 2B, 2B1, 2C, 

2C1, 2C2, 2S1 and 2S2 model turboshaft 

engines with a fuel filter pre-blockage 

pressure switch, part number 9 550 17 200 

0, and serial number (S/N) 00001 to 12753,

(e) Unsafe Condition 

This AD was prompted by reports from the 

manufacturer of non-conforming fuel filter 

pre-blockage pressure switches manufactured 

before December 2016. The FAA is issuing 

this AD to prevent the non-conformity of the 

fuel filter pre-blockage pressure switch, 

which can cause its non-activation in case of 

fuel system contamination, with consequent 

opening of the by-pass without indication in 

the cockpit. The unsafe condition, if not 

addressed, could result in uncommanded inflight shut-down of the engine, an emergency 

autorotation landing on a single engine 

helicopter, or an uncommanded in-flight 

shut-down of both engines on a twin engine 

helicopter. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) After the effective date of this AD, 

during the pre-flight inspection for the first 

flight of each day the engine is operated, 

perform a visual inspection of the fuel filter 

by-pass indicator to determine if the fuel 

filter by-pass indicator pop-up has been 

activated. 

(2) Within the next 300 hydro-mechanical 

metering unit (HMU) operating hours or 180 

days after the effective date of this AD, 

whichever occurs first, perform an 

operational test of the fuel filter pre-blockage 

pressure switch in accordance with Task 73– 

23–01–750–801–A01—Pre-Blockage Pressure 

Switch of the Fuel Filter Tests (Electrical), 

dated November 30, 2012, (the Task) from the 

Turbomeca Arriel 2 S1 Maintenance Manual. 

(3) During any visual inspection required 

by paragraph (g)(1) of this AD, if the fuel 

filter by-pass indicator pop-up has been 

activated or, during the operational test 

required by paragraph (g)(2) of this AD, any 

discrepancy is detected as described by the 

Task, before next flight, replace the fuel filter 

pre-blockage pressure switch with a part 

eligible for installation. 

(4) The actions required by paragraph (g)(1) 

of this AD may be performed by the owner/ 

operator (pilot) holding at least a private pilot 

certificate, and must be entered into the 

aircraft records showing compliance with 

this AD, in accordance with 14 CFR 43.9 

(a)(1) through (4) and 14 CFR 91.417(a)(2)(v). 

The records must be maintained as required 

by 14 CFR 91.417, 121.380, or 135.439. 

(h) Terminating Action 

Passing the operational test (no failure 

detected) of the fuel filter pre-blockage 

pressure switch, as required by paragraph 

(g)(2) of this AD, or replacement of the fuel 

filter pre-blockage pressure switch with a 

part eligible for installation, constitutes a 

terminating action for the repetitive visual 

inspections required by paragraph (g)(1) of 

this AD for that engine. 

(i) Definition 

A part eligible for installation is a fuel filter 

pre-blockage pressure switch that is not 

listed in the Applicability, paragraph (c), of 

this AD, or a fuel filter pre-blockage pressure 

switch that has passed the operational test 

(no discrepancies detected) required by 

paragraph (g)(2) of this AD. 

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, ECO Branch, FAA, has 

the authority to approve AMOCs for this AD, 

if requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19,

300 and ERJ 190–400 airplanes. AD 

2020–08–11 required revising the 

existing airplane flight manual (AFM) 

procedures associated with messages of 

smoke in the electronic bays presented 

on the respective engine indication and 

crew alerting system (EICAS). This AD 

continues to require revising the 

existing AFM procedures, and adds 

requirements for a terminating 

modification of the electrical wiring of 

the mid-electronic bay and backup 

smoke detectors; as specified in an 

Ageˆncia Nacional de Aviac ̧a ̃o Civil 

(ANAC) AD, which is incorporated by 

reference. This AD was prompted by a 

failure propagation test, which revealed 

that under certain conditions, the smoke 

detection system of the electrical bays 

erroneously indicated the presence of

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued AD 2020–08–11, 

Amendment 39–19903 (85 FR 27112, 

May 7, 2020) (AD 2020–08–11), which 

applied to all Yabora ̃ Indu ́ stria 

Aerona ́utica Model ERJ 190–300 and 

ERJ 190–400 airplanes. AD 2020–08–11 

required revising the existing AFM 

procedures associated with messages of 

smoke in the electronic bays presented 

on the respective EICAS. The FAA 

issued AD 2020–08–11 to provide the 

flightcrew with revised AFM procedures 

for responding to erroneous indications 

of smoke in the electrical bays presented 

on the EICAS. The AFM procedures are 

intended to prevent loss of all electrical 

digital current (DC) essential buses, 

causing loss of electrical power for 

critical systems of the airplane. 

Actions Since AD 2020–08–11 Was 

Issued 

Since the FAA issued AD 2020–08– 

11, the FAA has determined that it is 

necessary to mandate a modification to 

correct the root cause of erroneous 

indications of smoke in the electrical 

bays presented on the EICAS that will 

allow for removal of the AFM revision 

required by AD 2020–08–11. Production 

airplanes are not included in the 

applicability of this AD because the 

modification required by this AD is 

incorporated during production. 

ANAC, which is the aviation 

authority for Brazil, has issued ANAC 

AD 2021–02–01, effective February 15, 

2021; corrected February 23, 2021 

(ANAC AD 2021–02–01) (also referred 

to as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI); to correct an unsafe condition 

for all Yabora ̃ Indu ́ stria Aerona ́utica 

Model ERJ 190–300 and ERJ 190–400 

airplanes. ANAC AD 2021–02–01 

superseded ANAC Emergency AD 2019– 

12–01, effective December 9, 2019 

(which corresponds to FAA AD 2020– 

08–11). 

This AD was prompted by a failure 

propagation test, which revealed that 

when complete loss of the electrical DC 

essential bus 2 was induced, the smoke 

detection system of the forward and aft 

electrical bays erroneously indicated the 

presence of smoke via the respective 

EICAS messages. When these messages 

are displayed, the existing AFM 

procedures require the flightcrew to 

turn off the essential electrical buses DC 

ESS BUS 1 and DC ESS BUS 3. The 

FAA is issuing this AD to address a loss 

of all electrical DC essential buses, and 

consequent loss of electrical power for 

critical systems of the airplane. See the 

MCAI for additional background 

information. 

Explanation of Retained Requirements 

Although this AD does not explicitly 

restate the requirements of AD 2020– 

08–11, this AD retains all of the 

requirements of AD 2020–08–11. Those 

requirements are referenced in ANAC 

AD 2021–02–01, which, in turn, is 

referenced in paragraph (g) of this AD. 

Related Service Information Under 1 

CFR Part 51 

ANAC AD 2021–02–01 describes 

temporary revisions to the existing AFM 

procedures associated with messages of 

smoke in the electronic bays presented 

on the EICAS, and removal of those 

temporary revisions once a modification 

of certain electrical wiring is completed. 

ANAC AD 2021–02–01 also describes 

procedures for modification of electrical 

wiring of the mid-electronic bay and 

backup smoke detectors, which is 

terminating action for the temporary 

revisions to the AFM. 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 

because the FAA has evaluated all 

pertinent information and determined 


jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 86, No. 129 / Friday, July 9, 2021 / Rules and Regulations 36209 

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 ANAC AD 2021– 

02–01 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, ANAC AD 

2021–02–01 is incorporated by reference 

in this AD. This AD, therefore, requires 

compliance with ANAC AD 2021–02–01 

in its entirety, through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this AD. Service 

information specified in ANAC AD 

2021–02–01 that is required for 

compliance with ANAC AD 2021–02–01 

is available on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0456. 

FAA’s Justification and Determination 

of the Effective Date 

There are currently no domestic 

operators of these products. Therefore, 

the FAA finds that notice and 

opportunity for prior public comment 

are unnecessary and that good cause 

exists 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– 

2021–0456; Project Identifier MCAI– 

2021–00212–T’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the final 

rule, 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 final rule 

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 final rule. 

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 Krista Greer, 

Aerospace Engineer, Large Aircraft 

Section, International Validation 

Branch, FAA, 2200 South 216th St., Des 

Moines, WA 98198; telephone and fax 

206–231–3223; email krista.greer.@

faa.gov. Any commentary that the FAA 

receives which 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 

Currently, there are no affected U.S.- 

registered airplanes. If an affected 

airplane 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 FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Retained action from AD 2020–08–11 ......................... 1 work-hour × $85 per hour = $85 ............................... $0 $85 

New actions .................................................................. 6 work-hours × $85 per hour = $510 ........................... 0 510 

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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska.
