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 incorporated by reference. The
FAA is issuing this AD to address the
unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
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.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all ATR–GIE Avions de
Transport Re´gional Model ATR42–200,
–300, –320, and –500 airplanes; and
Model ATR72–101, –102, –201, –202,
–211, –212, and –212A airplanes. The
NPRM published in the Federal
Register on December 8, 2020 (85 FR
78974). The NPRM was prompted by inservice 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 NPRM proposed to
require revising the existing AFM and
applicable corresponding operational
procedures to provide emergency
procedures and limitations for operating
in severe icing conditions, as specified
in EASA AD 2020–0177.
The FAA is issuing 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.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The FAA has considered
the comment received. The Air Line
Pilots Association, International (ALPA)
stated that it supports the NPRM.
Conclusion
The FAA reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting this
final rule as proposed, except for 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.
Related Service Information Under 1
CFR Part 51
EASA AD 2020–0177 specifies
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.
Costs of Compliance
The FAA estimates that this AD
affects 59 airplanes of U.S. registry. The
FAA estimates the following costs to
comply with this AD:

Authority for This Rulemaking
Regulatory Findings
Adoption of the Amendment
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.
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,
(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.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:

SUPPLEMENTARY INFORMATION:
Background
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.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all ATR-GIE Avions de
Transport R[eacute]gional Model ATR42-200, -300, -320, and -500
airplanes; and Model ATR72-101, -102, -201, -202, -211, -212, and -212A
airplanes. The NPRM published in the Federal Register on December 8,
2020 (85 FR 78974). The NPRM 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 NPRM proposed to require revising the
existing AFM and applicable corresponding operational procedures to
provide emergency procedures and limitations for operating in severe
icing conditions, as specified in EASA AD 2020-0177.
The FAA is issuing 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.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA has considered the comment
received. The Air Line Pilots Association, International (ALPA) stated
that it supports the NPRM.
Conclusion
The FAA reviewed the relevant data, considered the comment
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for 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.

EASA AD 2020-0177 specifies 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.
Costs of Compliance
The FAA estimates that this AD affects 59 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

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 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.
