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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM).

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

SUMMARY: The FAA proposes to revise a notice of proposed rulemaking 
(NPRM) to supersede Airworthiness Directive (AD) 2021-09-13, which 
applies to certain ATR-GIE Avions de Transport R[eacute]gional Model 
ATR42-500 airplanes. This action revises the NPRM by including 
additional new or more restrictive airworthiness limitations. The FAA 
is proposing this AD to address the unsafe condition on these products. 
Since this action would 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 FAA must receive comments on this SNPRM by December 27, 
2022.

disclosure. If your comments responsive to this SNPRM 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 SNPRM, 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 SNPRM. Submissions containing CBI should 
be sent to Shahram Daneshmandi, Aerospace Engineer, Large Aircraft 
Section, FAA, International Validation Branch, 2200 South 216th St.,

[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.

Background

    The FAA issued AD 2021-09-13, Amendment 39-21527 (86 FR 27031, May 
19, 2021) (AD 2021-09-13), for certain ATR-GIE Avions de Transport 
R[eacute]gional Model ATR42-500 airplanes. AD 2021-09-13 requires 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. The 
FAA issued AD 2021-09-13 to prevent reduced structural integrity of the 
airplane.
    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD to 
supersede AD 2021-09-13 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 April 8, 2022 (87 FR 20783) (the NPRM). The 
NPRM was prompted by MCAI originated by the European Union Aviation 
Safety Agency (EASA), which is the Technical Agent for the Member 
States of the European Union. EASA issued AD 2021-0212, dated September 
17, 2021 (EASA AD 2021-0212), to correct an unsafe condition. The NPRM 
proposed to retain the requirements of AD 2021-09-13. The NPRM also 
proposed to require revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations.

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, EASA superseded EASA AD 2021-0212 
and issued EASA AD 2022-0063, dated April 8, 2022 (EASA AD 2022-0063). 
EASA AD 2022-0063 was issued because ATR-GIE Avions de Transport 
published Revision 16 of the ATR 42-400/-500 Time Limits Document 
(TLD), which included new or more restrictive maintenance tasks and 
airworthiness limitations. EASA subsequently superseded EASA AD 2022-
0063 and issued EASA AD 2022-0200, dated September 26, 2022 (EASA AD 
2022-0200) (also referred to after this as the MCAI). EASA AD 2022-0200 
states that since EASA AD 2022-0063 was issued, ATR-GIE Avions de 
Transport published Revision 17 of the ATR 42-400/-500 TLD, which 
includes new or more restrictive maintenance tasks and airworthiness 
limitations.
    EASA AD 2022-0200 applies to all ATR-GIE Avions de Transport 
R[eacute]gional Model ATR42-400 and -500 airplanes. Model ATR42-400 
airplanes are not certificated by the FAA and are not included on the 
U.S. type certificate data sheet; this proposed 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 29, 2022, must comply with the 
airworthiness limitations specified as part of the approved type design 
and referenced on the type certificate data sheet; this proposed AD 
therefore does not include those airplanes in the applicability.
    The FAA is proposing this AD to prevent reduced structural 
integrity of the airplane. You may examine EASA AD 2022-0200 in the AD 
docket at regulations.gov under Docket No. FAA-2022-0396.

Comments

    The FAA received a comment from The Air Line Pilots Association, 
International (ALPA), who supported the NPRM without change.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0200 describes new or more restrictive maintenance 
tasks and airworthiness limitations for airplane structures and for 
safe life limits of the components.

[[Page 67844]]

    This proposed AD would also require EASA AD 2020-0263, dated 
December 1, 2020, which the Director of the Federal Register approved 
for incorporation by reference as of June 23, 2021 (86 FR 27031, May 
19, 2021).
    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

    These products have been approved by the aviation authority of 
another country and are 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 described 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 these same type designs.
    Certain changes described above expand the scope of the NPRM. As a 
result, it is necessary to reopen the comment period to provide 
additional opportunity for the public to comment on this SNPRM.

Proposed AD Requirements in This SNPRM

    This proposed AD would retain the requirements of AD 2021-09-13. 
This proposed AD would also require revising the existing maintenance 
or inspection program, as applicable, to incorporate additional new or 
more restrictive maintenance tasks and airworthiness limitations, which 
are specified in EASA AD 2022-0200 described previously, as proposed 
for incorporation by reference. Any differences with EASA AD 2022-0200 
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 (AMOC) according to 
paragraph (m)(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 2021-09-13 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 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.
