47252 Federal Register / Vol. 86, No. 161 / Tuesday, August 24, 2021 / Proposed Rules 

Your request should state that the NRC 

does not routinely edit comment 

submissions to remove such information 

before making the comment 

submissions available to the public or 

entering the comment into ADAMS. 

I. Discussion 

On July 1, 2021, the NRC solicited 

comments on the proposed NuScale 

small modular reactor design 

certification. The NRC proposed 

amendments to its regulations so that 

applicants or licensees intending to 

construct and operate a NuScale 

standard design may do so by 

referencing the design certification rule. 

The public comment period was 

originally scheduled to close on August 

30, 2021. 

On July 27, 2021, the NRC received a 

public comment (ADAMS Accession 

No. ML21209A763) requesting that the 

comment period for the proposed rule 

be extended by an additional 90 days. 

The request states that due to the large 

volume of related documents that need 

to be reviewed, additional time is 

needed to submit comments. No specific 

basis was given for requesting an 

additional 90 days to prepare 

comments. 

The NRC seeks to ensure that the 

public has a reasonable opportunity to 

provide the NRC with comments on this 

proposed action. The NRC 

acknowledges that the rulemaking 

documents contain a significant amount 

of information. However, the NRC is 

also responsible for deciding whether to 

issue a design certification within a 

reasonable time. Accordingly, to balance 

these interests, the NRC has decided to 

extend the comment period for the 

proposed rule for an additional 45 days. 

A 45-day extension provides a 

reasonable opportunity for all 

stakeholders to review these documents 

and to develop informed comments on 

these documents, while not unduly 

delaying the NRC’s final decision on the 

design certification. 

The NRC has decided to extend the 

public comment period for the proposed 

rule until October 14, 2021, to allow 

more time for members of the public to 

submit their comments. 

Dated: August 17, 2021.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2018–19–28, which applies to certain 

Embraer S.A. Model ERJ 190–100 STD, 

–100 LR, –100 ECJ, –100 IGW, –200 

STD, –200 LR, and –200 IGW airplanes; 

and AD 2014–16–16, which applies to 

all of those airplane models. AD 2014– 

16–16 requires, for certain airplanes, 

retorquing and replacing the pylon 

lower link fittings, and for all airplanes, 

repetitively retorquing those fittings. AD 

2018–19–28 requires modifying the 

attaching parts of the pylon lower link 

fittings. Since the FAA issued AD 2014– 

16–16 and AD 2018–19–28, the FAA 

finds it necessary to change the 

compliance time for the modification. 

This proposed AD would require an 

inspection of certain shear pins, 

replacement if necessary, and revised 

compliance times for the modification, 

as specified in an Ageˆncia Nacional de 

Aviac ̧a ̃o Civil (ANAC) AD, which is 

proposed for incorporation by reference. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products. 

DATES: The FAA must receive comments 

on this proposed AD by October 8, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

The FAA issued AD 2014–16–16, 

Amendment 39–17940 (79 FR 48018, 

August 15, 2014) (AD 2014–16–16), 

which applies to all Embraer S.A. Model 

ERJ 190–100 STD, –100 LR, –100 ECJ, 

–100 IGW, –200 STD, –200 LR, and 

–200 IGW airplanes. AD 2014–16–16 

requires, for certain airplanes, 

retorquing and replacing the pylon 

outboard and inboard lower link 

fittings, and for all airplanes, that AD 

also requires repetitive retorquing of the 

pylon outboard and inboard lower link 

fittings. The FAA issued AD 2014–16– 

16 to prevent loss of a shear pin on the 

pylon outboard and inboard lower link 

fittings, which could result in failure of 

the fitting and consequent separation of 

the engine from the wing. 

The FAA also issued AD 2018–19–28, 

Amendment 39–19429 (83 FR 48935, 

September 28, 2018) (AD 2018–19–28), 

which applies to certain Embraer S.A. 

Model ERJ 190–100 STD, –100 LR, –100 

ECJ, –100 IGW, –200 STD, –200 LR, and 

–200 IGW airplanes. AD 2018–19–28 

requires modification of the attaching 

parts of the left-hand (LH) and righthand (RH) pylon lower link fittings, 

inboard and outboard positions. The 

FAA issued AD 2018–19–28 to prevent 

loss of integrity of the engine pylon 

lower link fittings, possibly resulting in 

separation of the engine from the wing. 

AD 2018–19–28 specified that 

accomplishing certain actions required 

by that AD terminated certain 

requirements of AD 2014–16–16. 

Actions Since ADs 2014–16–16 and 

2018–19–28 Were Issued 

Since the FAA issued ADs 2014–16– 

16 and 2018–19–28, cracked nuts and 

an external shear pin with damaged 

threads were found when the pylon 

outboard and inboard lower link fittings 

were retorqued. In addition, the FAA 

finds it necessary to change the 

compliance time for the modification of 

the pylon lower link fitting attaching 

parts, in order to prevent loss of 

integrity of the engine pylon lower link 

fittings. 

ANAC, which is the aviation 

authority for Brazil, has issued ANAC 

AD 2020–06–02R02, effective November 

30, 2020 (ANAC AD 2020–06–02R02) 

(also referred to as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for certain Yabora ̃ Indu ́ stria 

Aerona ́utica S.A. Model ERJ 190–100 

STD, –100 LR, –100 ECJ, –100 IGW, 

–200 STD, –200 LR, and –200 IGW 

airplanes. ANAC AD 2020–06–02R02 

supersedes ANAC AD 2014–07–01 

(which corresponds to FAA AD 2014– 

16–16) and ANAC AD 2017–01–01 

(which corresponds to FAA AD 2018– 

19–28). Model 190–100 SR airplanes are 

not certificated by the FAA and are not 

included on the U.S. type certificate 

data sheet; this AD therefore does not 

include those airplanes in the 

applicability. 

This proposed AD was prompted by 

reports of bushing migration, loss of nut 

torque on the engine pylon lower 

inboard and outboard link fittings, a 

loose lower link assembly, and damaged 

nuts. The existing torque values could 

cause damage to the nuts, which could 

lead to loss of the shear pins of the 

pylon outboard and inboard lower link 

fittings. In addition, the existing 

compliance time for the modification of 

the pylon lower link fitting attaching 

parts has been found to be inadequate 

to address the unsafe condition. The 

FAA is proposing this AD to prevent 

loss of integrity of the lower link fittings 

of the engine pylon, which could result 

in separation of the engine from the 

wing. See the MCAI for additional 

background information. 

Explanation of Retained Requirements 

Although this proposed AD does not 

explicitly restate the requirements of 

ADs 2014–16–16 and 2018–19–28, this 

proposed AD would retain all of the 

requirements of AD 2014–16–16 and AD 

2018–19–28. Those requirements are 

referenced in ANAC AD 2020–06– 

02R02, which, in turn, is referenced in 

paragraph (g) of this proposed AD. 

Related Service Information Under 1 

CFR Part 51 

ANAC AD 2020–06–02R02 describes 

procedures for: Reduction of the torque 

to be applied to the castellated nuts of 

the external shear pins; inspection of 

the external shear pin; modification of 

the attaching parts of the LH and RH 

pylon lower link fittings, inboard and 

outboard positions; and repetitive 

retorquing of the pylon outboard and 

inboard lower link fittings. 

This AD also requires Embraer 

Service Bulletin 190–54–0013, dated 

November 27, 2012; and Embraer 

Service Bulletin 190LIN–54–0004, dated 

December 20, 2012; which the Director 

of the Federal Register approved for 

incorporation by reference as of 

September 2, 2014 (79 FR 48018, August 

15, 2014). 

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. 

Explanation of Change to 

Manufacturer’s Name Specified in This 

NPRM 

The FAA has revised references to the 

manufacturer’s name specified 

throughout this NPRM to identify the 

manufacturer name as published in the 

most recent type certificate data sheet 

for the affected models.

47254 Federal Register / Vol. 86, No. 161 / Tuesday, August 24, 2021 / Proposed Rules 

FAA’s Determination and Requirements 

of This Proposed AD 

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 proposing this AD 

because the FAA evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

ANAC AD 2020–06–02R02 described 

previously, as proposed for 

incorporation by reference, except for 

any differences identified as exceptions 

in the regulatory text of this proposed 

AD, and except as discussed under 

‘‘Differences Between this Proposed AD 

and the MCAI.’’ 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate ANAC AD 2020–06–02R02 

by reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with ANAC AD 2020–06– 

02R02 in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Service information required by ANAC 

AD 2020–06–02R02 for compliance will 

be available at https:// 

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0692 after the FAA final rule is 

published. 

Differences Between This Proposed AD 

and the MCAI 

The applicability of ANAC AD 2020– 

06–02R02 is limited to certain airplanes 

of the affected models. However, the 

applicability of this proposed AD 

includes all airplanes. Because the 

affected lock assemblies are rotable 

parts, the FAA has determined that 

these parts could later be installed on 

airplanes that were initially delivered 

with the acceptable lock assemblies, 

thereby subjecting those airplanes to the 

unsafe condition. The FAA has 

confirmed that the requirement in 

paragraph (w) of ANAC AD 2020–06– 

02R02 is applicable to the expanded 

group of airplanes. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 85 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Retained actions from AD 

2014–16–16.

6 work-hours × $85 per hour = $510 ..................................... $0 $510 Up to $43,350 

Retained actions from AD 

2018–19–28.

Up to 270 work-hours × $85 per hour = Up to $22,950 ........ $3,200 Up to $26,150 Up to 

$2,222,750 

New proposed actions ............ Up to 274 work-hours × $85 per hour = Up to $23,290 ........ Up to $3,180 Up to $26,470 Up to 

$2,249,950 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition actions specified in 

this proposed AD. 

According to the manufacturer, some 

or all of the costs of this proposed AD 

may be covered under warranty, thereby 

reducing the cost impact on affected 

operators. The FAA does not control 

warranty coverage for affected operators. 

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 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed 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 proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

Certificate Previously Held by Embraer 

S.A.): Docket No. FAA–2021–0692; Project 

Identifier MCAI–2020–01585–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by October 8, 

2021. 

(b) Affected ADs 

(1) This AD replaces AD 2014–16–16, 

Amendment 39–17940 (79 FR 48018, August 

15, 2014) (AD 2014–16–16). 

(2) This AD also replaces AD 2018–19–28, 

Amendment 39–19429 (83 FR 48935, 

September 28, 2018) (AD 2018–19–28). 

(c) Applicability 

This AD applies to all Yabora ̃ Indu ́ stria 

Aerona ́utica S.A. (type certificate previously 

held by Embraer S.A.) Model ERJ 190–100 

STD, –100 LR, –100 ECJ, –100 IGW, –200 

STD, –200 LR, and –200 IGW airplanes, 

certificated in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 54, Nacelles/pylons. 

(e) Reason 

This AD was prompted by reports of 

bushing migration, loss of nut torque on the 

engine pylon lower inboard and outboard 

link fittings, a loose lower link assembly, and 

damaged nuts, and the need to shorten the 

compliance time for the modification of the 

pylon lower link fitting attaching parts. The 

FAA is issuing this AD to prevent loss of 

integrity of the lower link fittings of the 

engine pylon, which could lead to separation 

of the engine from the wing. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements

(j) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Large Aircraft 

Section, International Validation 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, send your request to your 

principal inspector or responsible Flight 

Standards Office, as appropriate. If sending 

information directly to the Large Aircraft 

Section, International Validation Branch, 

send it to the attention of the person 

identified in paragraph (k)(2) of this AD. 

Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. Before using any 

approved AMOC, notify your appropriate 

principal inspector, or lacking a principal 

inspector, the manager of the responsible 

Flight Standards Office. 

(2) Contacting the Manufacturer: For any 

requirement in this AD to obtain instructions 

from a manufacturer, the instructions must 

be accomplished using a method approved 

by the Manager, Large Aircraft Section, 

International Validation Branch, FAA; or 

ANAC; or ANAC’s authorized Designee. If 

approved by the ANAC Designee, the 

approval must include the Designee’s 

authorized signature. 

(3) Required for Compliance (RC): Except 

as specified by paragraph (h) of this AD: For 

service information that contains steps that 

are labeled as Required for Compliance (RC), 

the provisions of paragraphs (j)(3)(i) and (ii) 

of this AD apply. 

(i) The steps labeled as RC, including 

substeps under an RC step and any figures 

identified in an RC step, must be done to 

comply with the AD. If a step or substep is 

labeled ‘‘RC Exempt,’’ then the RC 

requirement is removed from that step or 

substep. An AMOC is required for any 

deviations to RC steps, including substeps 

and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps, 

including substeps and identified figures, can 

still be done as specified, and the airplane 

can be put back in an airworthy condition.
