36210 Federal Register / Vol. 86, No. 129 / Friday, July 9, 2021 / Rules and Regulations 

Adoption of 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: 

■ a. Removing airworthiness directive 

(AD) 2020–08–11, Amendment 39– 

19903 (85 FR 27112, May 7, 2020), and 

■ b. Adding the following new AD: 

2021–12–14 Yabora ̃ Indu ́ stria Aerona ́utica 

S.A. (Type Certificate Previously Held 

by Embraer S.A.): Amendment 39– 

21601; Docket No. FAA–2021–0456; 

Project Identifier MCAI–2021–00212–T. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective July 26, 2021. 

(b) Affected ADs 

This AD replaces AD 2020–08–11, 

Amendment 39–19903 (85 FR 27112, May 7, 

2020) (AD 2020–08–11). 

(c) Applicability 

This AD applies to Yabora ̃ Indu ́ stria 

Aerona ́utica S.A. (type certificate previously 

held by Embraer S.A.) Model ERJ 190–300 

and ERJ 190–400 airplanes, certificated in 

any category, identified in Ageˆncia Nacional 

de Aviac ̧a ̃o Civil (ANAC) AD 2021–02–01, 

effective February 15, 2021; corrected 

February 23, 2021 (ANAC AD 2021–02–01). 

(d) Subject 

Air Transport Association (ATA) of 

America Code 24, Electrical power. 

(e) Reason 

This AD was prompted by a failure 

propagation test, which revealed that when 

complete loss of the electrical digital current 

(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 engine 

indication and crew alerting system (EICAS) 

messages, and by the determination that a 

terminating modification is necessary to 

correct the root cause of the unsafe condition. 

The FAA is issuing this AD to address the 

potential loss of all electrical DC essential 

buses, and consequent loss of electrical 

power for critical systems of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, ANAC AD 2021–02–01. 

(h) Exceptions to ANAC AD 2021–02–01 

(1) Where ANAC AD 2021–02–01 refers to 

its effective date, this AD requires using the 

effective date of this AD. 

(2) Where ANAC AD 2021–02–01 refers to 

December 9, 2019 (the effective date of 

ANAC Emergency AD 2019–12–01), this AD 

requires using May 22, 2020 (the effective 

date of AD 2020–08–11). 

(3) The ‘‘Alternative Methods of 

Compliance (AMOC)’’ section of ANAC AD 

2021–02–01 does not apply to this AD. 

(4) Where Part II, paragraph (b)(2), of 

ANAC AD 2021–02–01 specifies that after 

modification of the electrical wiring of the 

mid electronic bay and backup smoke 

detectors the temporary airplane flight 

manual (AFM) revisions ‘‘must be removed,’’ 

this AD requires removing the temporary 

AFM revisions before further flight after 

completing the modification required by Part 

II, paragraph (b)(1), of ANAC AD 2021–02– 

01. 

(i) 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

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it establishes 

Class E airspace at Missoula, MT, to 

ensure the safety and management of 

IFR operations in the National Airspace 

System. 

History 

The FAA published a notice of 

proposed rulemaking (NPRM) in the 

Federal Register (86 FR 20468; April 20, 

2021) for Docket No. FAA–2021–0207 to 

establish Class E airspace at Missoula, 

MT. Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. One comment, in 

favor of the proposed action, was 

received. 

Subsequent to the publication of the 

NPRM, the FAA determined that the 

proposed Class E6 airspace for 

Missoula, MT included a minor overlap 

into the proposed Class E6 airspace for 

Great Falls, MT (86 FR 18485; April 9, 

2021). To remove the overlapping 

airspace, an additional geographic point 

has been added to the Missoula, MT 

Class E6 airspace legal description. This 

change does not have a significant 

impact on the proposed airspace 

boundaries in the NPRM. The 

geographic point that has been added to 

the Final Rule’s legal description is ‘‘lat 

47°41′18′′ N, long 112°36′32′′ W.’’ 

Class E6 airspace designations are 

published in paragraph 6006 of FAA 

Order 7400.11E, dated July 21, 2020, 

and effective September 15, 2020, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document will be 

published subsequently in the Order. 

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document amends FAA Order 

7400.11E, Airspace Designations and 

Reporting Points, dated July 21, 2020, 

and effective September 15, 2020. FAA 

Order 7400.11E is publicly available as 

listed in the ADDRESSES section of this 

document. FAA Order 7400.11E lists 

Class A, B, C, D, and E airspace areas, 

air traffic service routes, and reporting 

points. 

The Rule 

This amendment to 14 CFR part 71 

establishes Class E en route domestic 

airspace extending upward from 1,200 

feet above the surface at Missoula, MT. 

This action provides controlled airspace 

to facilitate vectoring of IFR aircraft 

under the control of Salt Lake City and 

Seattle ARTCCs. The airspace also 

ensures proper containment of IFR 

aircraft operating on direct routes where 

the current en route structure is 

insufficient. 

FAA Order 7400.11, Airspace 

Designations and Reporting Points, is 

published yearly and effective on 

September 15. 

Regulatory Notices and Analyses 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current, is non-controversial, and 

unlikely to result in adverse or negative 

comments. It, therefore: (1) Is not a 

‘‘significant regulatory action’’ under 

Executive Order 12866; (2) is not a 

‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that will only affect air 

traffic procedures and air navigation, it 

is certified that this rule, when 

promulgated, would not have a 

significant economic impact on a 

substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

Environmental Review 

The FAA has determined that this 

action qualifies for categorical exclusion 

under the National Environmental 

Policy Act in accordance with FAA 

Order 1050.1F, ‘‘Environmental 

Impacts: Policies and Procedures,’’ 

paragraph 5–6.5a. This airspace action 

is not expected to cause any potentially 

significant environmental impacts, and 

no extraordinary circumstances exist 

that warrant the preparation of an 

environmental assessment.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; correction. 

SUMMARY: The Federal Aviation 

Administration (FAA) is correcting a 

final rule that appeared in the Federal 

Register on June 16, 2021. The rule 

modified the Class E airspace extending 

upward from 1,200 feet above the 

surface at Missoula International 

Airport, Missoula, MT. The Final Rule 

inadvertently used the word ‘‘about’’ 

instead of ‘‘above’’ when describing the 

airspace area. This action corrects the 

legal description for the Class E airspace 

extending upward from 1,200 feet above 

the surface. 

DATES: Effective 0901 UTC, August 12, 

2021. The Director of the Federal 

Register approves this incorporation by 

reference action under 1 CFR part 51, 

subject to the annual revision of FAA 

Order 7400.11 and publication of

SUPPLEMENTARY INFORMATION: 

History 

The FAA published a final rule in the 

Federal Register (86 FR 31907; June 16, 

2021) for Docket FAA–2021–0208 

amending the Class E airspace 

extending upward from 1,200 feet above 

the surface at Missoula International 

Airport, Missoula, MT. Subsequent to 

publication, the FAA identified an error 

in the wording used to describe this 

Class E airspace area. This action 

corrects that error. 

Class E5 airspace designations are 

published in paragraph 6005 of FAA 

Order 7400.11E, dated July 21, 2020, 

and effective September 15, 2020, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document will be 

published subsequently in the Order. 

Correction to Final Rule 

Accordingly, pursuant to the 

authority delegated to me, Amendment 

of the Class E Airspace; Missoula, MT, 

published in the Federal Register of 

June 16, 2021 (86 FR 31907), FR Doc. 

2021–12662, is corrected as follows: 

§ 71.1 [Corrected] 

■ 1. On page 31908, in the third column, 

beginning with line 35, the legal 

description for ANM MT E5 is corrected 

to read: 

ANM MT E5 Missoula, MT [Amended] 

Missoula International Airport, MT
