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

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directives (AD) 2000-23-
04 R1 and AD 2018-20-14, which applied to certain ATR-GIE Avions de 
Transport R[eacute]gional Model ATR42-500 airplanes. AD 2000-23-04 R1 
and AD 2018-20-14 required revising the maintenance or inspection 
program, as applicable, to incorporate new and/or more restrictive 
maintenance requirements and airworthiness limitations. This AD 
requires 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 incorporated by reference. This AD was prompted by 
the FAA's determination that new or more restrictive airworthiness 
limitations are necessary. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective June 23, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 23,

SUPPLEMENTARY INFORMATION:

Background

    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. 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. Airplanes with an original 
airworthiness certificate or original export certificate of 
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.
    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 to supersede 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 applied to certain ATR-GIE Avions de 
Transport R[eacute]gional Model ATR42-500 airplanes. The SNPRM 
published in the Federal Register on February 24, 2021 (86 FR 11169). 
The FAA preceded the SNPRM with a notice of proposed rulemaking (NPRM) 
that published in the Federal Register on October 29, 2020 (85 FR 
68503). The NPRM was prompted by the FAA's determination that new or 
more restrictive airworthiness limitations are necessary. The NPRM 
proposed to require revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. The SNPRM proposed to require revising the 
existing

[[Page 27032]]

maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2020-0263.
    The FAA is issuing this AD to address reduced structural integrity 
of the airplane. See the MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the SNPRM 
or on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.
    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 2020-0263 describes new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This AD also requires 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.

Costs of Compliance

    The FAA estimates that this AD affects 9 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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. 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 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

    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.
