SUPPLEMENTARY INFORMATION: 

Discussion 

The ANAC, which is the aviation 

authority for Brazil, has issued ANAC 

AD 2020–07–02, effective July 21, 2020 

(ANAC AD 2020–07–02) (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 EMB–135, EMB–145, 

–145EP, –145ER, –145LR, –145MP, 

–145MR, and –145XR airplanes. Model 

EMB–145EU, EMB–145LU, and EMB– 

145MK 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. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Yabora ̃ Indu ́ stria 

Aerona ́utica S.A. Model EMB–135, 

EMB–145, –145EP, –145ER, –145LR, 

–145MP, –145MR, and –145XR 

airplanes. The NPRM published in the 

Federal Register on November 27, 2020 

(85 FR 75964). The NPRM was 

prompted by reports that calculations 

provided by the ATTCS are incorrect 

under certain conditions. The NPRM 

proposed to require updating the 

software of the installed FADEC 

systems, as specified in ANAC AD 

2020–07–02. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Changes Made to This AD 

Paragraph (c) of this AD has been 

revised to correct the reference to Model 

EMB–145ER airplanes. 

Certain paragraph designations have 

been corrected in the regulatory text of 

this AD. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety and the 

public interest require adopting this 

final rule with the changes described 

previously and minor editorial changes. 

The FAA has determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

The FAA also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this final rule. 

Related Service Information Under 1 

CFR Part 51 

ANAC AD 2020–07–02 describes 

procedures for updating the software of 

the installed FADEC systems to version 

B9.4 or B9.4.1. 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 494 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

5 work-hours × $85 per hour = $425 .......................................................................................... $0 $425 $209,950 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will not have a 

10744 Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Rules and Regulations 

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, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

List of Subjects in 14 CFR Part 39

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 adding 

the following new airworthiness 

directive: 

2021–04–09 Yabora ̃ Indu ́ stria Aerona ́utica 

S.A. (Type Certificate Previously Held 

by Embraer S.A.): Amendment 39– 

21430; Docket No. FAA–2020–1035; 

Project Identifier MCAI–2020–01017–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective March 30, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Yabora ̃ Indu ́ stria 

Aerona ́utica S.A. Model EMB–135BJ, 

–135ER, –135KE, –135KL, and –135LR 

airplanes; and Model EMB–145, –145EP, 

–145ER, –145LR, –145MP, –145MR, and 

–145XR airplanes; certificated in any 

category; as identified in Ageˆncia Nacional 

de Aviac ̧a ̃o Civil (ANAC) AD 2020–07–02,

incorrect under certain conditions. The FAA 

is issuing this AD to address the risk of overprediction of the operational margins, 

without the necessary alert being provided to 

the flightcrew in some situations. This 

condition, if not corrected, could lead to a 

performance reduction during takeoff, in 

which case the airplane may not be able to 

take off safely.

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 2020–07–02. 

(h) Exceptions to ANAC AD 2020–07–02

Airworthiness Directives; Pilatus 

Aircraft Ltd. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for Pilatus 

Aircraft Ltd. (Pilatus) Model PC–12/47E 

airplanes. This AD was prompted by 

mandatory continuing airworthiness 

information (MCAI) originated by an 

aviation authority of another country to 

identify and correct an unsafe condition 

on an aviation product. The MCAI 

describes the unsafe condition as
