The FAA is superseding
Airworthiness Directive (AD) 2020–23–
13, which applied to all ATR—GIE
Avions de Transport Re´gional Model
ATR42–200, –300, and –320 airplanes.
AD 2020–23–13 required a one-time
inspection for discrepancies of the wire
bundles between the left- and righthand angle of attack (AOA) probes and
the crew alerting computer, and,
depending on findings, applicable
corrective actions. This AD continues to
require the actions in AD 2020–23–13,
and also requires for certain airplanes,
modifying the captain stick shaker
wiring, and for all airplanes, revising
the existing aircraft flight manual (AFM)
and applicable corresponding
operational procedures to incorporate
procedures for the stick pusher/shaker,
as specified in a European Union
Aviation Safety Agency (EASA) AD,
which is incorporated by reference. This
AD was prompted by false activation of
the stall warning system due to wiring
damage on the wire bundle between an
AOA probe and the crew alerting
computer, and the development of a
wiring modification and AFM update to
address the unsafe condition. The FAA
is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective October 5,
2021.

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2021–0024,
dated January 19, 2021 (EASA AD
2021–0024) (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, and –320 airplanes.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2020–23–13,
Amendment 39–21330 (85 FR 73407,
November 18, 2020) (AD 2020–23–13).
AD 2020–23–13 applied to all ATR—
GIE Avions de Transport Re´gional
Model ATR42–200, –300, and –320
airplanes. The NPRM published in the
Federal Register on May 13, 2021 (86
FR 26195). The NPRM was prompted by
false activation of the stall warning
system due to wiring damage on the
wire bundle between an AOA probe and
the crew alerting computer, and the
development of a wiring modification
and AFM update to address the unsafe
condition. The NPRM proposed to
continue to require the actions in AD
2020–23–13, and also proposed to
require for certain airplanes, modifying
the captain stick shaker wiring, and for
all airplanes, revising the existing AFM
and applicable corresponding
operational procedures to incorporate
procedures for the stick pusher/shaker,
as specified in EASA AD 2021–0024.
The FAA is issuing this AD to address
false activation of the stall warning
system, which could result in loss of
control of the airplane during take-off
and landing phases. 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)
indicated its support for the NPRM.
Explanation of Changes to This AD
The FAA has added paragraph (h)(7)
of this AD to clarify what
‘‘discrepancies’’ are since the ATR
Airworthiness Operators Message
(AOM) referred to in EASA AD 2021–
0024 does not use the word
‘‘discrepancy.’’
The FAA has revised paragraph
(h)(4)(ii) of this AD to clarify that, for
inspections done on or before December
3, 2020, those reports must be submitted
‘‘within 30 days after December 3,
2020.’’ In the proposed AD, the FAA
inadvertently stated that the reports
were to be submitted ‘‘within 30 days
after the effective date of this AD.’’
However, this requirement is retained
from AD 2020–23–13 and the FAA
intends for the compliance time to
remain the same.
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 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
EASA AD 2021–0024 describes
procedures for a one-time detailed
visual inspection of the wire bundles
between the left- and right-hand AOA
probes and the crew alerting computer
for discrepancies (including, but not
limited to, wire damage, missing or
damaged conduits, and incorrect routing
of wiring and conduits), and, depending
on findings, applicable corrective
actions. EASA AD 2021–0024 also
describes procedures for modifying the
captain stick shaker wiring, and
amending the systems limitations
section of the applicable AFM to
incorporate procedures for the stick
pusher/shaker. 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.

Federal Register / Vol. 86, No. 166 / Tuesday, August 31, 2021 / Rules and Regulations
The FAA estimates that it would take
about 1 work-hour per product to
comply with the proposed reporting
requirement in this AD. The average
labor rate is $85 per hour. Based on
these figures, the FAA estimates the cost
of reporting the inspection results on
U.S. operators to be $2,210, or $85 per
product.
The FAA has received no definitive
data on which to base the cost estimates
for the on-condition actions specified in
this AD.
Paperwork Reduction Act
A federal agency may not conduct or
sponsor, and a person is not required to
respond to, nor shall a person be subject
to penalty for failure to comply with a
collection of information subject to the
requirements of the Paperwork
Reduction Act unless that collection of
information displays a current valid
OMB control number. The control
number for the collection of information
required by this AD is 2120–0056. The
paperwork cost associated with this AD
has been detailed in the Costs of
Compliance section of this document
and includes time for reviewing
instructions, as well as completing and
reviewing the collection of information.
Therefore, all reporting associated with
this AD is mandatory. Comments
concerning the accuracy of this burden
and suggestions for reducing the burden
should be directed to the Information
Collection Clearance Officer, Federal
Aviation Administration, 10101
Hillwood Parkway, Fort Worth, TX
76177–1524.
khammond on DSKJM1Z7X2PROD with RULES
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.
List of Subjects in 14 CFR Part 39
(e) Reason
This AD was prompted by false activation
of the stall warning system due to wiring
damage on the wire bundle between an angle
of attack (AOA) probe and the crew alerting
computer, and the development of a wiring
modification and aircraft flight manual
(AFM) update to address the unsafe
condition. The FAA is issuing this AD to
address this condition, which could result in
loss of control of the airplane during take-off
and landing phases.
(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, European Union Aviation
Safety Agency (EASA) AD 2021–0024, dated
January 19, 2021 (EASA AD 2021–0024).
(c) Applicability
This AD applies to all ATR—GIE Avions
de Transport Re´gional Model ATR42–200,
–300, and –320 airplanes, certificated in any
category.
(h) Exceptions to EASA AD 2021–0024
(1) Where EASA AD 2021–0024 refers to its
effective date, this AD requires using the
effective date of this AD.
(2) Where EASA AD 2021–0024 refers to
‘‘the effective date of EASA AD 2020–0221,’’
this AD requires using December 3, 2020 (the
effective date of AD 2020–23–13).
(3) The ‘‘Remarks’’ section of EASA AD
2021–0024 does not apply to this AD.
(4) Paragraph (3) of EASA AD 2021–0024
specifies to report inspection results to
ATR—GIE Avions de Transport Re´gional
within a certain compliance time. For this
AD, report inspection results at the
applicable time specified in paragraph
(h)(4)(i) or (ii) of this AD.
(i) If the inspection was done on or after
December 3, 2020 (the effective date of AD
2020–23–13): Submit the report within 30
days after the inspection.
(ii) If the inspection was done before
December 3, 2020 (the effective date of AD
2020–23–13): Submit the report within 30
days after December 3, 2020.
(5) Paragraphs (5) and (6) of EASA AD
2021–0024 specify amending ‘‘the applicable
AFM [aircraft flight manual] of that aeroplane
by inserting the AFM change provided in
Appendix 1 of this [EASA] AD,’’ however
this AD requires amending ‘‘the existing
AFM and applicable corresponding
operational procedures to incorporate the
limitations and procedures specified in
Appendix 1 of EASA AD 2021–0024.’’
(6) Where paragraphs (5) and (6) of EASA
AD 2021–0024 specify to ‘‘inform all flight
crews, and, thereafter, operate the aeroplane
accordingly,’’ this AD does not require those
actions as those actions are already required
by existing FAA operating regulations.
(7) Where paragraph (1) of EASA AD 2021–
0024 refers to ‘‘discrepancies,’’ for this AD
discrepancies include, but are not limited to,
wire damage, missing or damaged conduits,
and incorrect routing of wiring and conduits.

ACTION: Final rule.
AGENCY:
This action amends the Class
E airspace extending upward from 700
feet above the surface at Pocahontas
Municipal Airport, Pocahontas, IA. This
action is the result of an airspace review
due to the decommissioning of the
Pocahontas non-directional beacon

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-23-
13, which applied to all ATR--GIE Avions de Transport R[eacute]gional
Model ATR42-200, -300, and -320 airplanes. AD 2020-23-13 required a
one-time inspection for discrepancies of the wire bundles between the
left- and right-hand angle of attack (AOA) probes and the crew alerting
computer, and, depending on findings, applicable corrective actions.
This AD continues to require the actions in AD 2020-23-13, and also
requires for certain airplanes, modifying the captain stick shaker
wiring, and for all airplanes, revising the existing aircraft flight
manual (AFM) and applicable corresponding operational procedures to
incorporate procedures for the stick pusher/shaker, as specified in a
European Union Aviation Safety Agency (EASA) AD, which is incorporated
by reference. This AD was prompted by false activation of the stall
warning system due to wiring damage on the wire bundle between an AOA
probe and the crew alerting computer, and the development of a wiring
modification and AFM update to address the unsafe condition. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective October 5, 2021.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 5,
2021.

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0024, dated January 19, 2021
(EASA AD 2021-0024) (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, and -320 airplanes.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2020-23-13, Amendment 39-21330 (85 FR
73407, November 18, 2020) (AD 2020-23-13). AD 2020-23-13 applied to all
ATR--GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and
-320 airplanes. The NPRM published in the Federal Register on May 13,
2021 (86 FR 26195). The NPRM was prompted by false activation of the
stall warning system due to wiring damage on the wire bundle between an
AOA probe and the crew alerting computer, and the development of a
wiring modification and AFM update to address the unsafe condition. The
NPRM proposed to continue to require the actions in AD 2020-23-13, and
also proposed to require for certain airplanes, modifying the captain
stick shaker wiring, and for all airplanes, revising the existing AFM
and applicable corresponding operational procedures to incorporate
procedures for the stick pusher/shaker, as specified in EASA AD 2021-
0024.
The FAA is issuing this AD to address false activation of the stall
warning system, which could result in loss of control of the airplane
during take-off and landing phases. 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)
indicated its support for the NPRM.
Explanation of Changes to This AD
The FAA has added paragraph (h)(7) of this AD to clarify what
``discrepancies'' are since the ATR Airworthiness Operators Message
(AOM) referred to in EASA AD 2021-0024 does not use the word
``discrepancy.''
The FAA has revised paragraph (h)(4)(ii) of this AD to clarify
that, for inspections done on or before December 3, 2020, those reports
must be submitted ``within 30 days after December 3, 2020.'' In the
proposed AD, the FAA inadvertently stated that the reports were to be
submitted ``within 30 days after the effective date of this AD.''
However, this requirement is retained from AD 2020-23-13 and the FAA
intends for the compliance time to remain the same.
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 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
EASA AD 2021-0024 describes procedures for a one-time detailed
visual inspection of the wire bundles between the left- and right-hand
AOA probes and the crew alerting computer for discrepancies (including,
but not limited to, wire damage, missing or damaged conduits, and
incorrect routing of wiring and conduits), and, depending on findings,
applicable corrective actions. EASA AD 2021-0024 also describes
procedures for modifying the captain stick shaker wiring, and amending
the systems limitations section of the applicable AFM to incorporate
procedures for the stick pusher/shaker. 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 26 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2020-23- Up to 10 work-hours $0 Up to $850......... Up to $22,100.
13. x $85 per hour =
Up to $850.
New proposed actions............. 4 work-hours x $85 $100 $440............... $11,440.
per hour = $340.
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.
[[Page 48492]]
The FAA estimates that it would take about 1 work-hour per product
to comply with the proposed reporting requirement in this AD. The
average labor rate is $85 per hour. Based on these figures, the FAA
estimates the cost of reporting the inspection results on U.S.
operators to be $2,210, or $85 per product.
The FAA has received no definitive data on which to base the cost
estimates for the on-condition actions specified in this AD.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the
Information Collection Clearance Officer, Federal Aviation
Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.
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.
