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 Directive (AD) 
2018-18-05, which applies to all ATR-GIE Avions de Transport 
R[eacute]gional Model ATR42-200, -300, and -320 airplanes; and AD 2020-
09-16, which applies to all ATR-GIE Avions de Transport R[eacute]gional 
Model ATR42-200, -300, and -320 airplanes. AD 2018-18-05 and AD 2020-
09-16 require revising the existing maintenance or inspection program, 
as applicable, to incorporate new or more restrictive airworthiness 
limitations. Since the FAA issued AD 2018-18-05 and AD 2020-09-16, the 
FAA has determined that new or more restrictive airworthiness 
limitations are necessary. This proposed AD would retain the 
requirements of AD 2020-09-16. This proposed AD would also 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 
is proposed for incorporation 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 May 23, 
2022.

Background

    The FAA issued AD 2018-18-05, Amendment 39-19384 (83 FR 44463, 
August 31, 2018) (AD 2018-18-05), which applies to certain ATR-GIE 
Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 
airplanes. AD 2018-18-05 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive maintenance requirements and airworthiness limitations. The 
FAA issued AD 2018-18-05 to prevent reduced structural integrity of the 
airplane.
    The FAA also issued AD 2020-09-16, Amendment 39-19912 (85 FR 29596, 
May 18, 2020) (AD 2020-09-16), which applies to all ATR-GIE Avions de 
Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. AD 
2020-09-

[[Page 19819]]

16 requires revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. The FAA issued AD 2020-09-16 to address reduced structural 
integrity of the airplane. AD 2020-09-16 also specifies that 
accomplishing the revision required by paragraph (g) of that AD 
terminates all requirements of AD 2018-18-05, but AD 2020-09-16 did not 
supersede AD 2018-18-05.

Actions Since AD 2018-18-05 and AD 2020-09-16 Were Issued

    Since the FAA issued AD 2018-18-05 and AD 2020-09-16, the FAA has 
determined that new or more restrictive airworthiness limitations are 
necessary.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0211, dated September 17, 2021 
(EASA AD 2021-0211) (also referred to as the MCAI), to correct an 
unsafe condition for all ATR-GIE Avions de Transport R[eacute]gional 
Model ATR42-200, -300, and -320 airplanes.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to prevent reduced structural integrity of the 
airplane. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0211 describes new or more restrictive airworthiness 
limitations for airplane structures and components.
    This AD would also require EASA AD 2019-0256, dated October 17, 
2019, which the Director of the Federal Register approved for 
incorporation by reference as of June 22, 2020 (85 FR 29596, May 18, 
2020).
    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, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain the requirements of AD 2020-09-16. 
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 
2021-0211 described previously, as proposed for incorporation by 
reference. Revising the existing maintenance or inspection program, as 
specified in EASA AD 2021-0211, would terminate the retained 
requirements from AD 2020-09-16. Any differences with EASA AD 2021-0211 
are identified as exceptions in the regulatory text of this proposed 
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 (AMOC) according to 
paragraph (m)(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 developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate EASA AD 2021-0211 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0211 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 EASA AD 2021-0211 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 EASA AD 2021-
0211. Service information required by EASA AD 2021-0211 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2022-0395 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), intervals, or CDCCLs may be used unless the actions, 
intervals, and CDCCLs are approved as an AMOC in accordance with the 
procedures specified in the AMOCs paragraph under ``Additional FAA AD 
Provisions.'' This new format includes a ``New Provisions for 
Alternative Actions, Intervals, and CDCCLs'' paragraph that does not 
specifically refer to AMOCs, but operators may still request an AMOC to 
use an alternative action, interval, or CDCCL.

Costs of Compliance

    The FAA estimates that this proposed AD affects 26 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 2020-09-16 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. Since

[[Page 19820]]

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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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.
