Discussion The FAA issued AD 2000–23–04 R1, Amendment 39–12174 (66 FR 19381, April 16, 2001) (AD 2000–23–04 R1) and AD 2018–20–14, Amendment 39– 19448 (83 FR 52123, October 16, 2018) (AD 2018–20–14). ADs 2000–23–04 R1 and 2018–20–14 require actions to address an unsafe condition on certain ATR–GIE Avions de Transport Re´gional Model ATR42–500 airplanes. ADs 2000–23–04 R1 and 2018–20–14 require revising the maintenance or inspection program, as applicable, to incorporate new and/or more restrictive maintenance requirements and airworthiness limitations. The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD to supersede AD 2000–23–04 R1 and AD 2018–20–14 that would apply to certain ATR–GIE Avions de Transport Re´gional Model ATR42–500 airplanes. The NPRM published in the Federal Register on October 29, 2020 (85 FR 68503) (the NPRM). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary, as specified in EASA AD 2020–0136, dated June 18, 2020 (EASA AD 2020–0136). Actions Since the NPRM Was Issued Since the FAA issued the NPRM, the FAA has determined that new or more restrictive airworthiness limitations are necessary. The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0263, dated December 1, 2020 (EASA AD 2020–0263) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Model ATR 42–400 and ATR 42– 500 airplanes. EASA AD 2020–0263 supersedes EASA AD 2020–0136. Model ATR 42–400 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. EASA AD 2020–0263 refers to ATR ATR42–400/–500, Time Limits Document (TL), Revision 14, dated July 7, 2020. Airplanes with an original airworthiness certificate or original export certificate of E:\FR\FM\24FEP1.SGM 24FEP1 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Proposed Rules airworthiness issued after July 7, 2020, must comply with the airworthiness limitations specified as part of the approved type design and referenced on the type certificate data sheet; this AD, therefore, does not include those airplanes in the applicability. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is proposing this AD to address reduced structural integrity of the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2020–0263 describes new or more restrictive airworthiness limitations for airplane structures and safe life limits. This proposed AD would also require the following service information, which the Director of the Federal Register approved for incorporation by reference as of November 20, 2018 (83 FR 52123, October 16, 2018). • ATR ATR42–400/–500, Time Limits Document (TL), Revision 11, dated May 5, 2015. • ATR ATR42–400/–500 Time Limits Temporary Revision TR01/17, dated May 3, 2017. 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. khammond on DSKJM1Z7X2PROD with PROPOSALS Comments The FAA gave the public the opportunity to participate in developing this proposed AD. The FAA received no comments on the NPRM or on the determination of the cost to the public. FAA’s Determination and Requirements of This SNPRM 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 pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Certain changes described above expand the scope of the NPRM. As a result, the FAA has determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. VerDate Sep<11>2014 16:41 Feb 23, 2021 Jkt 253001 Proposed AD Requirements This proposed AD would retain the requirements of AD 2018–20–14. This proposed AD would also require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, which are specified in EASA AD 2020–0263 described previously, as incorporated by reference. Any differences with EASA AD 2020–0263 are identified as exceptions in the regulatory text of this AD. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections) and Critical Design Configuration Control Limitations (CDCCLs). Compliance with these actions and CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (n)(1) of this proposed AD. Costs of Compliance The FAA estimates that this proposed AD affects 9 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: The FAA estimates the total cost per operator for the retained actions from AD 2018–20–14 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the agency recognizes that this number may vary from operator to operator. In the past, the agency has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. The FAA estimates the total cost per operator for the new proposed actions to be $7,650 (90 work-hours × $85 per work-hour). 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 PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 11171 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 1.

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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening 
of comment period.

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

SUMMARY: The FAA is revising an earlier proposal to supersede 
Airworthiness Directives (AD) 2000-23-04 R1 and AD 2018-20-14, which 
apply to certain ATR-GIE Avions de Transport R[eacute]gional Model 
ATR42-500 airplanes. This action revises the notice of proposed 
rulemaking (NPRM) by including new or more restrictive airworthiness 
limitations. The FAA is proposing this AD to address the unsafe 
condition on these products. Since this action would

[[Page 11170]]

impose an additional burden over those in the NPRM, the FAA is 
reopening the comment period to allow the public the chance to comment 
on these changes.

DATES: The comment period for the NPRM published in the Federal 
Register on October 29, 2020 (85 FR 68503), is reopened.

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2020-0973; Project Identifier 
MCAI-2020-01113-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, 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 
the proposal 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 proposed AD.

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 NPRM 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 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 
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.

Discussion

    The FAA issued AD 2000-23-04 R1, Amendment 39-12174 (66 FR 19381, 
April 16, 2001) (AD 2000-23-04 R1) and AD 2018-20-14, Amendment 39-
19448 (83 FR 52123, October 16, 2018) (AD 2018-20-14). ADs 2000-23-04 
R1 and 2018-20-14 require actions to address an unsafe condition on 
certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 
airplanes. ADs 2000-23-04 R1 and 2018-20-14 require revising the 
maintenance or inspection program, as applicable, to incorporate new 
and/or more restrictive maintenance requirements and airworthiness 
limitations.
    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD to 
supersede AD 2000-23-04 R1 and AD 2018-20-14 that would apply to 
certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 
airplanes. The NPRM published in the Federal Register on October 29, 
2020 (85 FR 68503) (the NPRM). The NPRM was prompted by a determination 
that new or more restrictive airworthiness limitations are necessary, 
as specified in EASA AD 2020-0136, dated June 18, 2020 (EASA AD 2020-
0136).

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, the FAA has determined that new or 
more restrictive airworthiness limitations are necessary.
    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0263, dated December 1, 2020 
(EASA AD 2020-0263) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Model ATR 42-400 and ATR 42-500 airplanes. EASA AD 2020-0263 
supersedes EASA AD 2020-0136. Model ATR 42-400 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. EASA AD 2020-0263 refers to ATR ATR42-
400/-500, Time Limits Document (TL), Revision 14, dated July 7, 2020. 
Airplanes with an original airworthiness certificate or original export 
certificate of

[[Page 11171]]

airworthiness issued after July 7, 2020, must comply with the 
airworthiness limitations specified as part of the approved type design 
and referenced on the type certificate data sheet; this AD, therefore, 
does not include those airplanes in the applicability.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to address reduced structural integrity of the 
airplane. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0263 describes new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This proposed AD would also require the following service 
information, which the Director of the Federal Register approved for 
incorporation by reference as of November 20, 2018 (83 FR 52123, 
October 16, 2018).
     ATR ATR42-400/-500, Time Limits Document (TL), Revision 
11, dated May 5, 2015.
     ATR ATR42-400/-500 Time Limits Temporary Revision TR01/17, 
dated May 3, 2017.
    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.

Comments

    The FAA gave the public the opportunity to participate in 
developing this proposed AD. The FAA received no comments on the NPRM 
or on the determination of the cost to the public.

FAA's Determination and Requirements of This SNPRM

    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 pertinent information and determined an 
unsafe condition exists and is likely to exist or develop on other 
products of the same type design.
    Certain changes described above expand the scope of the NPRM. As a 
result, the FAA has determined that it is necessary to reopen the 
comment period to provide additional opportunity for the public to 
comment on this SNPRM.

Proposed AD Requirements

    This proposed AD would retain the requirements of AD 2018-20-14. 
This proposed AD would also require revising the existing maintenance 
or inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations, which are specified in EASA AD 
2020-0263 described previously, as incorporated by reference. Any 
differences with EASA AD 2020-0263 are identified as exceptions in the 
regulatory text of this AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
Critical Design Configuration Control Limitations (CDCCLs). Compliance 
with these actions and CDCCLs is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(n)(1) of this proposed AD.

Costs of Compliance

    The FAA estimates that this proposed AD affects 9 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 
proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2018-20-14 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. In the past, the agency has estimated that this action 
takes 1 work-hour per airplane. Since operators incorporate maintenance 
or inspection program changes for their affected fleet(s), the FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate.
    The FAA estimates the total cost per operator for the new proposed 
actions to be $7,650 (90 work-hours x $85 per work-hour).

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.
