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 EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0177, dated August 11, 2020 (EASA AD 2020–0177) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all ATR—GIE Avions de Transport Re´gional Model ATR42–200, –300, –320, –400, and –500 airplanes; and Model ATR72 airplanes. Model ATR42– 400 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 in-service data which revealed that the minimum operating airspeeds in severe PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 78975 icing conditions, computed to provide adequate stall margins, do not provide sufficient margins to stall speeds at high bank angle while exiting severe icing conditions. The FAA is proposing this AD to address airplane stalling due to inadvertent exposure to severe icing conditions, which could result in loss of control of the airplane. See the MCAI for additional background information. Other Related Rulemaking The FAA issued AD 96–09–28, Amendment 39–9604 (61 FR 20646, May 7, 1996) (AD 96–09–28), for all ATR—GIE Avions de Transport Re´gional Model ATR42 and ATR72 series airplanes. AD 96–09–28, among other things, prohibits operation of the airplane in certain icing conditions unless modifications are accomplished or alternative procedures and training are adopted and requires restrictions on the use of autopilot in certain conditions. The FAA issued AD 96–09– 28 to address the potential hazards associated with operating the airplane in severe icing conditions. The FAA issued AD 99–09–19, Amendment 39–11152 (64 FR 23766, May 4, 1999) (AD 99–09–19), for all Model ATR42 and ATR72 series airplanes. AD 99–09–19 requires revising the AFM to provide the flightcrew with modified procedures and limitations for operating in severe icing conditions. The FAA issued AD 99–09–19 to prevent the airplane from stalling due to prolonged exposure to severe icing conditions, which could result in reduced performance and controllability of the airplane. This proposed AD would provide terminating action for paragraphs (a)(1) and (2) of AD 96–09–28 and all requirements of AD 99–09–19. Related Service Information Under 1 CFR Part 51 EASA AD 2020–0177 describes procedures for revising the AFM to provide emergency procedures and limitations for operating in severe icing conditions. 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 E:\FR\FM\08DEP1.SGM 08DEP1 78976 Federal Register / Vol. 85, No. 236 / Tuesday, December 8, 2020 / Proposed Rules described in the MCAI 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 EASA AD 2020–0177 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 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, EASA AD 2020–0177 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2020–0177 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in the EASA AD. Service information specified in EASA AD 2020–0177 that is required for compliance with EASA AD 2020–0177 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–1112 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 59 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 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $5,015 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. jbell on DSKJLSW7X2PROD with PROPOSALS 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: VerDate Sep<11>2014 16:14 Dec 07, 2020 Jkt 253001 (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.

Airworthiness Directives; ATR--GIE Avions de Transport 
R[eacute]gional Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 
airplanes; and Model ATR72 airplanes. This proposed AD was prompted by 
in-service data which revealed that the minimum operating airspeeds in 
severe icing conditions, computed to provide adequate stall margins, do 
not provide sufficient margins to stall speeds at high bank angle while 
exiting severe icing conditions. This proposed AD would require 
revising the existing aircraft flight manual (AFM) and applicable 
corresponding operational procedures to provide emergency procedures 
and limitations for operating in severe icing conditions, as specified 
in a European Union Aviation Safety Agency (EASA) AD, which is proposed

docket for this rulemaking.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0177, dated August 11, 2020 
(EASA AD 2020-0177) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42-200, -
300, -320, -400, and -500 airplanes; and Model ATR72 airplanes. Model 
ATR42-400 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 in-service data which revealed 
that the minimum operating airspeeds in severe icing conditions, 
computed to provide adequate stall margins, do not provide sufficient 
margins to stall speeds at high bank angle while exiting severe icing 
conditions. The FAA is proposing this AD to address airplane stalling 
due to inadvertent exposure to severe icing conditions, which could 
result in loss of control of the airplane. See the MCAI for additional 
background information.

Other Related Rulemaking

    The FAA issued AD 96-09-28, Amendment 39-9604 (61 FR 20646, May 7, 
1996) (AD 96-09-28), for all ATR--GIE Avions de Transport 
R[eacute]gional Model ATR42 and ATR72 series airplanes. AD 96-09-28, 
among other things, prohibits operation of the airplane in certain 
icing conditions unless modifications are accomplished or alternative 
procedures and training are adopted and requires restrictions on the 
use of autopilot in certain conditions. The FAA issued AD 96-09-28 to 
address the potential hazards associated with operating the airplane in 
severe icing conditions.
    The FAA issued AD 99-09-19, Amendment 39-11152 (64 FR 23766, May 4, 
1999) (AD 99-09-19), for all Model ATR42 and ATR72 series airplanes. AD 
99-09-19 requires revising the AFM to provide the flightcrew with 
modified procedures and limitations for operating in severe icing 
conditions. The FAA issued AD 99-09-19 to prevent the airplane from 
stalling due to prolonged exposure to severe icing conditions, which 
could result in reduced performance and controllability of the 
airplane.
    This proposed AD would provide terminating action for paragraphs 
(a)(1) and (2) of AD 96-09-28 and all requirements of AD 99-09-19.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0177 describes procedures for revising the AFM to 
provide emergency procedures and limitations for operating in severe 
icing conditions.
    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

[[Page 78976]]

described in the MCAI 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 EASA AD 2020-0177 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 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, EASA AD 2020-0177 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0177 in its 
entirety, through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this proposed AD. 
Using common terms that are the same as the heading of a particular 
section in the EASA AD does not mean that operators need comply only 
with that section. For example, where the AD requirement refers to 
``all required actions and compliance times,'' compliance with this AD 
requirement is not limited to the section titled ``Required Action(s) 
and Compliance Time(s)'' in the EASA AD. Service information specified 
in EASA AD 2020-0177 that is required for compliance with EASA AD 2020-
0177 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2020-1112 after the FAA 
final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 59 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.
