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 NPRM. Submissions containing CBI should be sent to the person identified in the FOR FURTHER INFORMATION CONTACT section. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. 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, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP 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. This proposed AD was prompted by reports that calculations provided by the ATTCS do not take into consideration the required engine air bleed during operations with a single engine and anti-ice system on. The FAA is proposing this AD to address the risk of over-prediction 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 E:\FR\FM\27NOP1.SGM 27NOP1 Federal Register / Vol. 85, No. 229 / Friday, November 27, 2020 / Proposed Rules is proposing this AD because the FAA evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. the aircraft may not be able to take off safely. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 ANAC AD 2020–07–02 describes procedures for updating the software of the installed FADECs 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. Proposed AD Requirements 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 and service information referenced above. The FAA This proposed AD would require accomplishing the actions specified in ANAC AD 2020–07–02 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 the European Union Aviation Safety Agency (EASA) to develop a process to use certain EASA ADs as the primary source of information for compliance with 75965 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 2020– 07–02 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with ANAC AD 2020–07–02 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information specified in ANAC AD 2020–07–02 that is required for compliance with ANAC AD 2020–07–02 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–1035 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 494 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed 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 jbell on DSKJLSW7X2PROD with PROPOSALS 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 VerDate Sep<11>2014 17:37 Nov 25, 2020 Jkt 253001 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) 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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

you actually treat as private, and that is relevant or responsive to 
this NPRM, 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 NPRM. Submissions containing CBI should be sent to the 
person identified in the FOR FURTHER INFORMATION CONTACT section. Any 
commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

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 Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. Model 
EMB-135, EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP 
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.
    This proposed AD was prompted by reports that calculations provided 
by the ATTCS do not take into consideration the required engine air 
bleed during operations with a single engine and anti-ice system on. 
The FAA is proposing this AD to address the risk of over-prediction 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

[[Page 75965]]

the aircraft may not be able to take off safely. See the MCAI for 
additional background information.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2020-07-02 describes procedures for updating the software 
of the installed FADECs 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.

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 
and service information referenced above. The FAA is proposing this AD 
because the FAA evaluated all the relevant information and determined 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in ANAC AD 2020-07-02 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 the European Union 
Aviation Safety Agency (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 2020-07-02 will be incorporated by 
reference in the FAA final rule. This proposed AD would, therefore, 
require compliance with ANAC AD 2020-07-02 in its entirety, through 
that incorporation, except for any differences identified as exceptions 
in the regulatory text of this proposed AD. Service information 
specified in ANAC AD 2020-07-02 that is required for compliance with 
ANAC AD 2020-07-02 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
1035 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 494 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

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) 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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. (Type 
Certificate Previously Held by Embraer S.A.): Docket No. FAA-2020-
1035; Project Identifier MCAI-2020-01017-T.

(a) Comments Due Date

    The FAA must receive comments by January 11, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Yabor[atilde] Ind[uacute]stria 
Aeron[aacute]utica S.A. Model EMB-135BJ, -135ER, -135KE, -135KL, and 
-135LR airplanes, EMB-145, -45ER, -145MR, -145LR, -145XR, -145MP, 
and -145EP, certificated in any category, as identified in 
Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD 
2020-07-02, effective July 21, 2020 (``ANAC AD 2020-07-02'').

(d) Subject

    Air Transport Association (ATA) of America Code 73, Engine fuel 
and control.

(e) Reason

    This AD was prompted by reports that calculations provided by 
the automatic takeoff thrust control system (ATTCS) are incorrect 
under certain conditions. The FAA is issuing this AD to address the 
risk of over-prediction of the operational margins,

[[Page 75966]]

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.

(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 2020-07-02.

(j) Exceptions to ANAC AD 2020-07-02

    (1) Where ANAC AD 2020-07-02 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Alternative method of compliance (AMOC)'' section of 
ANAC AD 2020-07-02 does not apply to this AD.

(k) 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

this AD. Information may be emailed to: [email protected]. 
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.
