Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This proposed AD was prompted by a report of an electrical contactor that failed with contacts in the intermediate position, causing the airplane to lose power to multiple electrical systems. This proposed AD would require repetitive operational tests of the affected part, and, depending on findings, accomplishment of applicable corrective action, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42
and ATR72 airplanes. This proposed AD was prompted by a report of an
electrical contactor that failed with contacts in the intermediate
position, causing the airplane to lose power to multiple electrical
systems. This proposed AD would require repetitive operational tests of
the affected part, and, depending on findings, accomplishment of
applicable corrective action, as specified in a European Union Aviation
Safety Agency (EASA) AD, which is proposed for incorporation by
reference (IBR). The FAA is proposing this AD to address the unsafe
condition on these products.

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

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2023-0181, dated October 13, 2023
(EASA AD 2023-0181) (also referred to as the MCAI), to correct an
unsafe condition for ATR--GIE Avions de Transport R[eacute]gional Model
ATR 42-200, ATR 42-300, ATR 42-320, ATR 42-400, ATR 42-500, ATR 72-101,
ATR 72-102, ATR 72-201, ATR 72-202, ATR 72-211, ATR 72-212, and ATR 72-
212A airplanes, except those on which ATR modification (mod) 05948 has
been embodied in production. Model ATR 42-400 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. The MCAI states that one event of
electrical failure has been reported on a pre-mod 05948 airplane,
possibly caused by a functional item number (FIN) 1PA contactor failing
with contacts in the intermediate position.
The FAA is proposing this AD to address an electrical failure. This
condition, if not addressed, could lead to temporary loss of the direct
current emergency electrical network and loss of control of the
airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-0222.
Related Service Information Under 1 CFR Part 51
EASA AD 2023-0181 specifies procedures for repetitive operational
tests on the contactor 1PA, and, depending on findings, accomplishment
of applicable corrective actions. Corrective actions include
replacement of the contactor. 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 ADDRESSES.
[[Page 8362]]
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 this 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 require accomplishing the actions specified
in EASA AD 2023-0181 described previously, except for any differences
identified as exceptions in the regulatory text 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 2023-0181 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2023-0181 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 2023-0181 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 2023-
0181. Service information required by EASA AD 2023-0181 for compliance
will be available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2024-0222
after the FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 49 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85........ $0 $85 $4,165 per test.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170.... $1,625 $1,795
------------------------------------------------------------------------
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.
