AGENCY: Notice of proposed rulemaking (NPRM). ACTION: The FAA proposes to supersede Airworthiness Directives (AD) 2000–23–26, AD 2018–14–11, and AD 2019–13–04, which apply to ATR— GIE Avions de Transport Re´gional Model ATR72 airplanes. AD 2019–13– 04 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance instructions and airworthiness limitations. Since the FAA issued AD 2019–13–04, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products. SUMMARY: The FAA must receive comments on this proposed AD by December 17, 2020.

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 2019–13–04, Amendment 39–19677 (84 FR 35028, July 22, 2019) (‘‘AD 2019–13–04’’), for certain ATR—GIE Avions de Transport Re´gional Model ATR72 airplanes. AD 2019–13–04 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance instructions and airworthiness limitations. The FAA issued AD 2019– 13–04 to address fatigue cracking and damage in principal structural elements, which could result in reduced structural integrity of the airplane. AD 2019–13– 04 specifies that accomplishing the revision required by paragraph (g) of that AD terminates all requirements of AD 2000–23–26, Amendment 39–11999 (65 FR 70775, November 28, 2000) (‘‘AD 2000–23–26’’), AD 2008–04–19 R1, Amendment 39–16069 (74 FR 56713, PO 00000 Frm 00038 Fmt 4702 Sfmt 4702 69273 November 3, 2009) (‘‘AD 2008–04–19 R1’’), and AD 2018–14–11 Amendment 39–19331 (83 FR 34031, July 19, 2018) (‘‘AD 2018–14–11’’);. AD 2008–04–19 R1 was superseded by AD 2020–09–16, Amendment 39–19912 (85 FR 29596, May 18, 2020). This proposed AD would therefore supersede AD 2000–23–26, AD 2018–14–11, and AD 2019–13–04. Actions Since AD 2019–13–04 Was Issued Since the FAA issued AD 2019–13– 04, 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 2020–0173, dated August 5, 2020 (‘‘EASA AD 2020–0173’’) (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 ATR72 airplanes. Airplanes with an original airworthiness certificate or original export certificate of airworthiness issued after December 12, 2019 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 fatigue cracking and damage in principal structural elements, which could result in reduced structural integrity of the airplane. See the MCAI for additional background information. Related IBR Material Under 1 CFR Part 51 EASA AD 2020–0173 describes new or more restrictive airworthiness limitations for airplane structures and safe life limits. This AD would also require ATR ATR72 Time Limits Document, Revision 16, dated January 30, 2018, which the Director of the Federal Register approved for incorporation by reference as of August 26, 2019 (84 FR 35028, July 22, 2019). 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 E:\FR\FM\02NOP1.SGM 02NOP1 69274 Federal Register / Vol. 85, No. 212 / Monday, November 2, 2020 / Proposed Rules 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 has 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. jbell on DSKJLSW7X2PROD with PROPOSALS Proposed AD Requirements This proposed AD would retain the requirements of AD 2019–13–04. 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 2020–0173 described previously, as incorporated by reference. Any differences with EASA AD 2020–0173 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). Compliance with these actions 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. 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 2020–0173 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2020–0173 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 VerDate Sep<11>2014 20:16 Oct 30, 2020 Jkt 253001 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 2020–0173 that is required for compliance with EASA AD 2020–0173 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–0972 after the FAA final rule is published. Airworthiness Limitation ADs Using the New Process The FAA’s process of incorporating by reference MCAI ADs as the primary source of information for compliance with corresponding FAA ADs has been limited to certain MCAI ADs (primarily those with service bulletins as the primary source of information for accomplishing the actions required by the FAA AD). However, the FAA is now expanding the process to include MCAI ADs that require a change to airworthiness limitation documents, such as airworthiness limitation sections. For these ADs that incorporate by reference an MCAI AD that changes airworthiness limitations, the FAA requirements are unchanged. Operators must revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in the new airworthiness limitation document. The airworthiness limitations must be followed according to 14 CFR 91.403(c) and 91.409(e). The previous format of the airworthiness limitation ADs included a paragraph that specified that no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in the AMOCs paragraph under ‘‘Other FAA Provisions.’’ This new format includes a ‘‘New Provisions for Alternative Actions, and Intervals’’ paragraph that does not specifically refer to AMOCs, but operators may still request an AMOC to use an alternative action or interval. Costs of Compliance The FAA estimates that this proposed AD affects 23 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 PO 00000 Frm 00039 Fmt 4702 Sfmt 4702 AD 2019–13–04 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 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.

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 supersede Airworthiness Directives (AD) 
2000-23-26, AD 2018-14-11, and AD 2019-13-04, which apply to ATR--GIE 
Avions de Transport R[eacute]gional Model ATR72 airplanes. AD 2019-13-
04 requires revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive maintenance 
instructions and airworthiness limitations. Since the FAA issued AD 
2019-13-04, the FAA has determined that new or more restrictive 
airworthiness limitations are necessary. This proposed AD would require 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
will be incorporated by reference. The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by December 
17, 2020.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

other information as described in 14 CFR 11.35, the FAA will post all 
comments we receive, 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 we receive 
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. 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 2019-13-04, Amendment 39-19677 (84 FR 35028, July 
22, 2019) (``AD 2019-13-04''), for certain ATR--GIE Avions de Transport 
R[eacute]gional Model ATR72 airplanes. AD 2019-13-04 requires revising 
the existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive maintenance instructions and 
airworthiness limitations. The FAA issued AD 2019-13-04 to address 
fatigue cracking and damage in principal structural elements, which 
could result in reduced structural integrity of the airplane. AD 2019-
13-04 specifies that accomplishing the revision required by paragraph 
(g) of that AD terminates all requirements of AD 2000-23-26, Amendment 
39-11999 (65 FR 70775, November 28, 2000) (``AD 2000-23-26''), AD 2008-
04-19 R1, Amendment 39-16069 (74 FR 56713, November 3, 2009) (``AD 
2008-04-19 R1''), and AD 2018-14-11 Amendment 39-19331 (83 FR 34031, 
July 19, 2018) (``AD 2018-14-11'');. AD 2008-04-19 R1 was superseded by 
AD 2020-09-16, Amendment 39-19912 (85 FR 29596, May 18, 2020). This 
proposed AD would therefore supersede AD 2000-23-26, AD 2018-14-11, and 
AD 2019-13-04.

Actions Since AD 2019-13-04 Was Issued

    Since the FAA issued AD 2019-13-04, 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 2020-0173, dated August 5, 2020 
(``EASA AD 2020-0173'') (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 
ATR72 airplanes.
    Airplanes with an original airworthiness certificate or original 
export certificate of airworthiness issued after December 12, 2019 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 fatigue cracking and damage in principal 
structural elements, which could result in reduced structural integrity 
of the airplane. See the MCAI for additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0173 describes new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This AD would also require ATR ATR72 Time Limits Document, Revision 
16, dated January 30, 2018, which the Director of the Federal Register 
approved for incorporation by reference as of August 26, 2019 (84 FR 
35028, July 22, 2019).
    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

[[Page 69274]]

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 has 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.

Proposed AD Requirements

    This proposed AD would retain the requirements of AD 2019-13-04. 
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 
2020-0173 described previously, as incorporated by reference. Any 
differences with EASA AD 2020-0173 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). 
Compliance with these actions 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.

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 2020-0173 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0173 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 2020-0173 that is required 
for compliance with EASA AD 2020-0173 will be available on the internet 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2020-0972 after the FAA final rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections) or intervals may be used unless the actions or intervals 
are approved as an alternative method of compliance (AMOC) in 
accordance with the procedures specified in the AMOCs paragraph under 
``Other FAA Provisions.'' This new format includes a ``New Provisions 
for Alternative Actions, and Intervals'' paragraph that does not 
specifically refer to AMOCs, but operators may still request an AMOC to 
use an alternative action or interval.

Costs of Compliance

    The FAA estimates that this proposed AD affects 23 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 2019-13-04 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.
