SUPPLEMENTARY INFORMATION: Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0249, dated November 11, 2020 (EASA AD 2020–0249) (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 ATR42–400 and –500 airplanes; and Model ATR72–101, –102, –201, –202, –211, –212, and –212A 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 AD was prompted by a report of damage found on a wire bundle connecting an AOA probe and a MFC, which can inhibit activation of the stick pusher without any indication to the E:\FR\FM\17DER1.SGM 17DER1 81796 Federal Register / Vol. 85, No. 243 / Thursday, December 17, 2020 / Rules and Regulations flight crew by the stall warning system. The FAA is issuing this AD to address latent failure of the stick pusher, which could result in loss of control of the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2020–0249 describes procedures for a repetitive operational test for discrepancies (including missing or incorrect annunciators, messages, indicators, warnings, or sounds) of the stall warning system and stick pusher in the flight configuration, an inspection for discrepancies (including damage to electrical routing and conduits, foreign object debris, electrical routing and conduits not properly attached) in the wiring bundles between AOA probes and MFCs, corrective action, and an inspection report. 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 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 referenced above. The FAA is issuing this AD because the FAA evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Requirements of This AD This AD requires accomplishing the actions specified in the MCAI described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD and except as discussed under ‘‘Differences Between this AD and the MCAI.’’ 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 2020–0249 is incorporated by reference VerDate Sep<11>2014 17:27 Dec 16, 2020 Jkt 253001 in this final rule. This AD, therefore, requires compliance with EASA AD 2020–0249 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this 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 2020–0249 that is required for compliance with EASA AD 2020–0249 is available on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 1133. Differences Between This AD and the MCAI The MCAI specifies a compliance for the inspection of the affected wiring within 750 FH (flight hours) or 5 months, whichever occurs first. For this AD, the compliance time for the inspection is within 750 FH or 4 months, whichever occurs first after the effective date of this AD. In developing an appropriate compliance time the FAA considered the State of Design authority’s recommendation and the degree of urgency associated with the subject unsafe condition. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because of the failure of the stick pusher without any indication to the flight crew by the stall warning system. The latent failure of the stick pusher could result in loss of control of the airplane. In addition, the compliance time for the required action is shorter than the time necessary for the public to comment and for publication of the final rule. Therefore, the FAA finds good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reasons stated above, the FAA finds that good cause exists for making this amendment effective in less than 30 days. Comments Invited The FAA invites you to send any written relevant data, views, or PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2020–1133; Project Identifier MCAI–2020–01515–T’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, 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 AD. Submissions containing CBI should be sent to Shahram Daneshmandi, Aerospace Engineer, Large Aircraft Section, International Validation Branch, FAA, 2200 South 216th St., Des Moines, WA 98198; telephone and fax 206–231–3220; email shahram.daneshmandi@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. E:\FR\FM\17DER1.SGM 17DER1 Federal Register / Vol. 85, No. 243 / Thursday, December 17, 2020 / Rules and Regulations Costs of Compliance 81797 FAA estimates the following costs to comply with this AD: The FAA estimates that this AD affects 28 airplanes of U.S. registry. The ESTIMATED COSTS FOR REQUIRED ACTIONS * Labor cost Parts cost Cost per product Up to 10 work-hours × $85 per hour = Up to $850. None ..................................................... Up to $850 ............................................ Cost on U.S. operators Up to $23,800. * Table does not include estimated costs for reporting. The FAA estimates that it takes about 1 work-hour per product to comply with the 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 wiring inspection results on U.S. operators to be $2,380, 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 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 VerDate Sep<11>2014 17:27 Dec 16, 2020 Jkt 253001 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 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, and (2) Will not affect intrastate aviation in Alaska.

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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 and ATR72 
airplanes. This AD was prompted by a report of damage found on a wire 
bundle connecting an angle-of-attack (AOA) probe and a multi-function 
computer (MFC), which can inhibit activation of the stick pusher 
without any indication to the flight crew by the stall warning system. 
This AD requires a repetitive operational test for discrepancies of the 
stall warning system and stick pusher in the flight configuration, an 
inspection for discrepancies in the wiring bundles between AOA probes 
and MFCs, and corrective action if necessary, 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.

DATES: This AD becomes effective January 4, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 4, 
2021.
    The FAA must receive comments on this AD by February 1, 2021.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0249, dated November 11, 2020 
(EASA AD 2020-0249) (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 ATR42-400 and 
-500 airplanes; and Model ATR72-101, -102, -201, -202, -211, -212, and 
-212A 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 AD was prompted by a report of damage found on a wire bundle 
connecting an AOA probe and a MFC, which can inhibit activation of the 
stick pusher without any indication to the

[[Page 81796]]

flight crew by the stall warning system. The FAA is issuing this AD to 
address latent failure of the stick pusher, which could result in loss 
of control of the airplane. See the MCAI for additional background 
information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0249 describes procedures for a repetitive operational 
test for discrepancies (including missing or incorrect annunciators, 
messages, indicators, warnings, or sounds) of the stall warning system 
and stick pusher in the flight configuration, an inspection for 
discrepancies (including damage to electrical routing and conduits, 
foreign object debris, electrical routing and conduits not properly 
attached) in the wiring bundles between AOA probes and MFCs, corrective 
action, and an inspection report. 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

    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 
referenced above. The FAA is issuing this AD because the FAA evaluated 
all pertinent information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Requirements of This AD

    This AD requires accomplishing the actions specified in the MCAI 
described previously, as incorporated by reference, except for any 
differences identified as exceptions in the regulatory text of this AD 
and except as discussed under ``Differences Between this AD and the 
MCAI.''

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 2020-0249 
is incorporated by reference in this final rule. This AD, therefore, 
requires compliance with EASA AD 2020-0249 in its entirety, through 
that incorporation, except for any differences identified as exceptions 
in the regulatory text of this 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 2020-0249 that is 
required for compliance with EASA AD 2020-0249 is available on the 
internet at https://www.regulations.gov by searching for and locating 
Docket No. FAA-2020-1133.

Differences Between This AD and the MCAI

    The MCAI specifies a compliance for the inspection of the affected 
wiring within 750 FH (flight hours) or 5 months, whichever occurs 
first. For this AD, the compliance time for the inspection is within 
750 FH or 4 months, whichever occurs first after the effective date of 
this AD. In developing an appropriate compliance time the FAA 
considered the State of Design authority's recommendation and the 
degree of urgency associated with the subject unsafe condition.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because of the failure of the stick pusher without any indication to 
the flight crew by the stall warning system. The latent failure of the 
stick pusher could result in loss of control of the airplane. In 
addition, the compliance time for the required action is shorter than 
the time necessary for the public to comment and for publication of the 
final rule. Therefore, the FAA finds good cause that notice and 
opportunity for prior public comment are impracticable. In addition, 
for the reasons stated above, the FAA finds that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2020-1133; Project 
Identifier MCAI-2020-01515-T'' at the beginning of your comments. The 
most helpful comments reference a specific portion of the final rule, 
explain the reason for any recommended change, and include supporting 
data. The FAA will consider all comments received by the closing date 
and may amend this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, 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 AD. Submissions containing CBI should be sent to Shahram 
Daneshmandi, Aerospace Engineer, Large Aircraft Section, International 
Validation Branch, FAA, 2200 South 216th St., Des Moines, WA 98198; 
telephone and fax 206-231-3220; email [email protected]. Any 
commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

[[Page 81797]]

Costs of Compliance

    The FAA estimates that this AD affects 28 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
----------------------------------------------------------------------------------------------------------------
Up to 10 work-hours x $85 per hour   None.................  Up to $850...........  Up to $23,800.
 = Up to $850.
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    The FAA estimates that it takes about 1 work-hour per product to 
comply with the 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 wiring inspection results on U.S. operators to be 
$2,380, 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 
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

    The FAA determined that 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, and
    (2) Will not affect intrastate aviation in Alaska.
