Federal Register / Vol. 86, No. 177 / Thursday, September 16, 2021 / Rules and Regulations 51597 

(b) Neither discovery nor oral 

hearings will be permitted in appeals 

from final SBA loan review decisions. 

(c) All appeals under this subpart will 

be decided solely on a review of the 

administrative record, the appeal 

petition, any response, any reply or 

supplemental pleading, and filings 

related to objection to the administrative 

record. 

§ 134.1210 Standard of review. 

The standard of review is whether the 

final SBA loan review decision was 

based on clear error of fact or law. The 

appellant has the burden of proof. 

§ 134.1211 Decision on appeal. 

(a) Time limits and contents. The 

Judge will issue his or her decision 

within 45 calendar days after the close 

of record, as practicable. The decision 

will contain findings of fact and 

conclusions of law, the reasons for such 

findings and conclusions, and any relief 

ordered. The decision will be served 

upon appellant and SBA utilizing the 

OHA Case Portal. 

(b) Initial decision. The Judge’s 

decision on the appeal is an initial 

decision. However, unless a request for 

reconsideration is filed pursuant to 

paragraph (c) of this section or the SBA 

Administrator, solely within the 

Administrator’s discretion, decides to 

review or reverse the initial decision 

pursuant to paragraph (d) of this 

section, an initial decision shall become 

the final decision of SBA 30 calendar 

days after its service. The discretionary 

authority of the Administrator does not 

create any additional rights of appeal on 

the part of an appellant not otherwise 

specified in SBA regulations in this 

chapter. Any decision pursuant to this 

subpart applies only to the PPP and 

does not apply to SBA’s 7(a) Loan 

Program generally or to any 

interpretation or application of the 

regulations in part 120 or 121 of this 

chapter. 

(c) Reconsideration. An initial 

decision of the Judge may be 

reconsidered. If a request for 

reconsideration is filed and the SBA 

Administrator does not exercise 

discretion to review or reverse the 

initial decision under paragraph (d) of 

this section, OHA will decide the 

request for reconsideration and OHA’s 

decision on the request for 

reconsideration is a reconsidered initial 

OHA decision. 

(1) Either SBA or appellant may 

request reconsideration by filing with 

the Judge and serving a petition for 

reconsideration within 10 calendar days 

after service of the Judge’s decision. The 

request for reconsideration must clearly 

show an error of fact or law material to 

the decision. SBA does not have to have 

filed a response to the borrower’s appeal 

petition to request reconsideration of 

the initial decision of the Judge. 

(2) The Judge may also reconsider a 

decision on his or her own initiative 

within 20 calendar days after service of 

the Judge’s decision. 

(3) A reconsidered initial OHA 

decision becomes the final decision of 

SBA 30 calendar days after its service 

unless the SBA Administrator, solely 

within the Administrator’s discretion, 

decides to review or reverse the 

reconsidered initial OHA decision 

under paragraph (d) of this section. The 

discretionary authority of the 

Administrator does not create any 

additional rights of appeal on the part 

of an appellant not otherwise specified 

in SBA regulations in this chapter. 

(d) Administrator review. Within 30 

calendar days after the service of an 

initial OHA decision or a reconsidered 

initial OHA decision of a Judge, the SBA 

Administrator, solely within the 

Administrator’s discretion, may elect to 

review and/or reverse an initial OHA 

decision or a reconsidered initial OHA 

decision. In the event that the 

Administrator elects to review and/or 

reverse an initial OHA decision and a 

timely request for reconsideration of a 

Judge’s initial decision is also filed by 

an appellant pursuant to paragraph (c) 

of this section, the Administrator will 

consider such request for 

reconsideration. The Administrator’s 

decision will become the final decision 

of the SBA upon issuance. 

(e) Precedent. Neither initial nor final 

decisions rendered by OHA under this 

subpart are precedential. 

(f) Publication. Final decisions are 

normally published without redactions 

on OHA’s website. PPP decisions will 

likely contain confidential business and 

financial information and/or personally 

identifiable information. Therefore, 

OHA, within its full discretion, may 

publish final decisions issued under 

this section with any necessary 

redactions. 

(g) Appeal to Federal district court. 

Final decisions may be appealed to the 

appropriate Federal district court only. 

§ 134.1212 Effects of the decision. 

OHA may affirm, reverse, or remand 

a final SBA loan review decision. If 

remanded, OHA no longer has 

jurisdiction over the matter unless a 

new appeal is filed as a result of a new 

final SBA loan review decision. 

§ 134.1213 Equal Access to Justice Act. 

A prevailing appellant is not entitled 

to recover attorney’s fees. Appeals to 

OHA from final SBA loan review 

decisions under the PPP are not 

proceedings that are required to be 

conducted by an Administrative Law 

Judge under § 134.603. 

§ 134.1214 Confidential information. 

If a filing or other submission made 

pursuant to an appeal in this subpart 

contains confidential business and 

financial information; personally 

identifiable information; source 

selection sensitive information; income 

tax returns; documents and information 

covered under § 120.1060 of this 

chapter; or any other exempt 

information, that information is not 

available to the public pursuant to the 

Freedom of Information Act (FOIA), 5 

U.S.C. 552.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued AD 2020–26–02, 

Amendment 39–21357 (85 FR 81790, 

December 17, 2020) (AD 2020–26–02), 

which applied to Yabora ̃ Indu ́ stria 

Aerona ́utica S.A. (type certificate 

previously held by Embraer S.A.) Model 

ERJ 190–400 airplanes. AD 2020–26–02 

required amending the existing AFM to 

incorporate a new limitation and revise 

certain normal procedures. The FAA 

issued AD 2020–26–02 to address 

uncontained release of the LPC rotor 1 

and damage to the engine and airplane 

structure, which could result in loss of 

control of the airplane. 

Actions Since AD 2020–26–02 Was 

Issued 

AD 2020–26–02 and the 

corresponding ANAC AD 2020–07–01 

considered their requirements interim 

action. ANAC AD 2020–07–01 indicated 

that further mandatory actions may be 

necessary as a result of the investigation 

into failures in engines similar to those 

on affected airplanes. The manufacturer 

has since developed upgraded EEC 

software that will prevent the unsafe 

condition. The FAA has determined that 

further rulemaking is necessary; this AD 

follows from that determination. 

Since the FAA issued AD 2020–26– 

02, ANAC, which is the aviation 

authority for Brazil, has issued ANAC 

AD 2020–07–01R01, effective March 26, 

2021 (ANAC AD 2020–07–01R01) (also 

referred to as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Model ERJ 190–400 

airplanes. ANAC AD 2020–07–01R01 

supersedes ANAC AD 2020–07–01. 

This AD was prompted by a report of 

an IFSD due in part to failure in the LPC 

rotor 1 during operation in high altitude 

at high thrust settings, and the 

development of upgraded EEC software, 

which eliminates the need for the 

amendments to the existing AFM 

required by AD 2020–26–02. The FAA 

is issuing this AD to address 

uncontained release of the LPC rotor 1 

and damage to the engine and airplane 

structure, which could result in loss of 

control 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– 

26–02, this AD retains all of the 

requirements of AD 2020–26–02. Those 

requirements are referenced in ANAC 

AD 2020–07–01R01, which, in turn, is 

referenced in paragraph (g) of this AD. 

Related Service Information Under 1 

CFR Part 51 

ANAC AD 2020–07–01R01 describes 

procedures for amending the existing 

AFM to incorporate a new limitation 

and revise the normal procedures to 

limit the engine N1 setting for flights 

above 33,000 ft. ANAC AD 2020–07– 

01R01 also describes procedures for 

upgrading the EEC software and 

subsequently removing the AFM 

amendments. 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 

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 the MCAI 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 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, ANAC AD 2020–07– 

01R01 is incorporated by reference in 

this AD. This AD requires compliance 

with ANAC AD 2020–07–01R01 in its 

entirety through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD. Service information required by 

ANAC AD 2020–07–01R01 for 

compliance will be available at https:// 

www.regulations.gov by searching for 

Federal Register / Vol. 86, No. 177 / Thursday, September 16, 2021 / Rules and Regulations 51599 

and locating Docket No. FAA–2021– 

0701 after this AD is published. 

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– 

2021–0701; Project Identifier MCAI– 

2021–00365–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 

206–231–3221. Any commentary that 

the FAA receives which is not 

specifically designated as CBI will be 

placed in the public docket for this 

rulemaking. 

Interim Action 

The FAA considers this AD interim 

action. Investigation into failures in 

engines similar to those installed on the 

affected airplanes will enable the 

manufacturer to obtain better insight 

into the nature, cause, and extent of the 

IFSDs, and eventually to develop final 

action to address the unsafe condition. 

Once final action has been identified, 

the FAA might consider further 

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

Action Labor cost Parts cost Cost per 

product 

Retained actions from AD 2020–26–02 ....................... 1 work-hour × $85 per hour = $85 .............................. $0 $85. 

New required actions .................................................... Up to 3 work-hours × $85 per hour = Up to $255 ....... 0 Up to $255. 

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 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.

Airworthiness Directives; Rolls-Royce 

Deutschland Ltd & Co KG (Type 

Certificate Previously Held by RollsRoyce plc) Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–15– 

12 for certain Rolls-Royce Deutschland 

Ltd & Co KG (RRD) Trent 1000 model 

turbofan engines. AD 2020–15–12 

required initial and repetitive ultrasonic 

or visual inspections of the 

intermediate-pressure compressor (IPC) 

stage 1 rotor blade root (front face), IPC 

stage 2 rotor blade root (front and rear 

face), and IPC shaft stage 2 dovetail post 

(front face), and removal of any cracked 

parts from service. AD 2020–15–12 also 

required an inspection after asymmetric 

power and cabin depressurization 

events. This AD was prompted by IPC 

rotor blade separations resulting in 

engine failures. This AD requires initial 

and repetitive ultrasonic or visual 

inspections of certain IPC stage 1 rotor 

blade root, IPC stage 2 rotor blade root, 

and IPC shaft stage 2 dovetail posts until 

replacement of the IPC stage 1 and stage 

2 rotor blades with redesigned IPC stage 

1 and stage 2 rotor blades in kitted sets. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective October 21, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of October 21, 2021.
