ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain MHI RJ Aviation ULC Model
CL–600–2D15 (Regional Jet Series 705)
and CL–600–2D24 (Regional Jet Series
900) airplanes. This proposed AD was
prompted by a notice from a supplier
reporting that torque wrenches used to
install the air driven generator (ADG)
downlock cam nut were out of
calibration, which resulted in a higher
torque level setting than required during
the initial production installation of the
affected cam nut. This proposed AD
would require replacement of the
affected ADG locking cam screw and
cam nut, as specified in a Transport
Canada AD, which is proposed for
incorporation by reference (IBR). 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 June 7, 2024.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Background
Transport Canada, which is the
aviation authority for Canada, has
issued Transport Canada AD CF–2023–
76, dated November 28, 2023 (Transport
Canada AD CF–2023–76) (also referred
to as the MCAI), to correct an unsafe
condition for certain MHI RJ Aviation
ULC Model CL–600–2D15 (Regional Jet
Series 705) and CL–600–2D24 (Regional
Jet Series 900) airplanes. The MCAI
states MHI RJ Aviation received a
supplier quality escape notice, reporting
that torque wrenches used to install the
ADG downlock cam nut were out of
calibration, which resulted in a higher
torque level setting than required during
the initial production installation of the
affected cam nut. This over-torque
condition could cause the screw and
cam to fail, which, if not corrected,
could result in the loss of the ADG
downlock mechanism functionality
upon airplane touchdown which
eliminates a critical power source for
the aircraft, leaving the flight crew with
the minimum flightdeck displays and
difficulty controlling the aircraft.
The FAA is proposing this AD to
address the unsafe condition on these
products.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2024–1006.

affected ADG locking cam screw and
cam nut. 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.
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
Transport Canada AD CF–2023–76
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 Transport Canada AD CF–
2023–76 by reference in the FAA final
rule. This proposed AD would,
therefore, require compliance with
Transport Canada AD CF–2023–76 in its
entirety through that incorporation,
except for any differences identified as
exceptions in the regulatory text of this
proposed AD. Service information
required by Transport Canada AD CF–
2023–76 for compliance will be
available at regulations.gov under
Docket No. FAA–2024–1006 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 24
airplanes of U.S. registry. The FAA
estimates the following costs to comply
with this proposed AD:

Up to $455 .....................................
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.

continues to read as follows:
■
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new airworthiness
directive:
■
MHI RJ Aviation ULC (Type Certificate
Previously Held by Bombardier, Inc.):
Docket No. FAA–2024–1006; Project
Identifier MCAI–2023–01222–T.
(a) Comments Due Date
The FAA must receive comments on this
airworthiness directive (AD) by June 7, 2024.
(b) Affected ADs
None.
(c) Applicability
This AD applies to MHI RJ Aviation ULC
(Type Certificate previously held by
Bombardier, Inc.) Model CL–600–2D15
(Regional Jet Series 705) and Model CL–600–
2D24 (Regional Jet Series 900) airplanes,
certificated in any category, as identified in
Transport Canada AD CF–2023–76, dated
November 28, 2023 (Transport Canada AD
CF–2023–76).
(d) Subject
Air Transport Association (ATA) of
America Code 24, Electrical power.
(e) Unsafe Condition
This AD was prompted by a notice from a
supplier reporting that torque wrenches used
to install the air driven generator (ADG)
downlock cam nut were out of calibration,
which resulted in a higher torque level
setting than required during the initial
production installation of the affected cam
nut. The FAA is issuing this AD to address
this over-torque condition that could cause
the screw and cam to fail. The unsafe
condition, if not addressed, could result in
the loss of the ADG downlock mechanism
functionality on aircraft touchdown which
eliminates a critical power source for the
aircraft, leaving the flight crew with the
minimum flightdeck displays and difficulty
controlling the aircraft.
The Proposed Amendment
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:

AGENCY:
The FAA proposes to
supersede Airworthiness Directive (AD)
2023–02–13, which applies to certain
Dassault Aviation Model FALCON
900EX airplanes. AD 2023–02–13
requires revising the existing
maintenance or inspection program, as
applicable, to incorporate new or more
restrictive airworthiness limitations.
Since the FAA issued AD 2023–02–13,
the FAA has determined that new or
more restrictive airworthiness
limitations are necessary. This proposed
AD would continue to require certain
actions in AD 2023–02–13 and 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 is
proposed for incorporation by reference
(IBR). The FAA is proposing this AD to
address the unsafe condition on these
products.

Background
The FAA issued AD 2023–02–13,
Amendment 39–22320 (88 FR 8740,
February 10, 2023) (AD 2023–02–13),
for certain Dassault Aviation Model
FALCON 900EX airplanes. AD 2023–
02–13 was prompted by an MCAI
originated by EASA, which is the
Technical Agent for the Member States
of the European Union. EASA issued
AD 2022–0144, dated July 11, 2022
(EASA AD 2022–0144) (which
corresponds to FAA AD 2023–02–13), to
correct an unsafe condition.
AD 2023–02–13 requires revising the
existing maintenance or inspection
program, as applicable, to incorporate
new or more restrictive airworthiness
limitations. The FAA issued AD 2023–
02–13 to address reduced structural
integrity of the airplane.
Actions Since AD 2023–02–13 Was
Issued
Since the FAA issued AD 2023–02–
13, EASA superseded AD 2022–0144

RIN 2120-AA64
Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate
Previously Held by Bombardier, Inc.) Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain MHI RJ Aviation ULC Model CL-600-2D15 (Regional Jet Series
705) and CL-600-2D24 (Regional Jet Series 900) airplanes. This proposed
AD was prompted by a notice from a supplier reporting that torque
wrenches used to install the air driven generator (ADG) downlock cam
nut were out of calibration, which resulted in a higher torque level
setting than required during the initial production installation of the
affected cam nut. This proposed AD would require replacement of the
affected ADG locking cam screw and cam nut, as specified in a Transport
Canada AD, which is proposed for incorporation by reference (IBR). 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 June 7,
2024.

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 Fatin
Saumik, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410,
Westbury, NY 11590; telephone 516-228-7300; email
[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
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2023-76, dated November 28, 2023
(Transport Canada AD CF-2023-76) (also referred to as the MCAI), to
correct an unsafe condition for certain MHI RJ Aviation ULC Model CL-
600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series
900) airplanes. The MCAI states MHI RJ Aviation received a supplier
quality escape notice, reporting that torque wrenches used to install
the ADG downlock cam nut were out of calibration, which resulted in a
higher torque level setting than required during the initial production
installation of the affected cam nut. This over-torque condition could
cause the screw and cam to fail, which, if not corrected, could result
in the loss of the ADG downlock mechanism functionality upon airplane
touchdown which eliminates a critical power source for the aircraft,
leaving the flight crew with the minimum flightdeck displays and
difficulty controlling the aircraft.
The FAA is proposing this AD to address the unsafe condition on
these products.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2024-1006.
Related Service Information Under 1 CFR Part 51
Transport Canada AD CF-2023-76 specifies procedures for replacing
the affected ADG locking cam screw and cam nut. 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.
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 Transport Canada AD CF-2023-76 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 Transport Canada AD CF-2023-76 by reference
in the FAA final rule. This proposed AD would, therefore, require
compliance with Transport Canada AD CF-2023-76 in its entirety through
that incorporation, except for any differences identified as exceptions
in the regulatory text of this proposed AD. Service information
required by Transport Canada AD CF-2023-76 for compliance will be
available at regulations.gov under Docket No. FAA-2024-1006 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 24 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
[[Page 30288]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 2 work-hours x $85 per hour = $285 Up to $455................ Up to $10,920.
$170.
----------------------------------------------------------------------------------------------------------------
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.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier,
Inc.): Docket No. FAA-2024-1006; Project Identifier MCAI-2023-01222-
T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by June 7, 2024.
(b) Affected ADs
None.
(c) Applicability
This AD applies to MHI RJ Aviation ULC (Type Certificate
previously held by Bombardier, Inc.) Model CL-600-2D15 (Regional Jet
Series 705) and Model CL-600-2D24 (Regional Jet Series 900)
airplanes, certificated in any category, as identified in Transport
Canada AD CF-2023-76, dated November 28, 2023 (Transport Canada AD
CF-2023-76).
(d) Subject
Air Transport Association (ATA) of America Code 24, Electrical
power.
(e) Unsafe Condition
This AD was prompted by a notice from a supplier reporting that
torque wrenches used to install the air driven generator (ADG)
downlock cam nut were out of calibration, which resulted in a higher
torque level setting than required during the initial production
installation of the affected cam nut. The FAA is issuing this AD to
address this over-torque condition that could cause the screw and
cam to fail. The unsafe condition, if not addressed, could result in
the loss of the ADG downlock mechanism functionality on aircraft
touchdown which eliminates a critical power source for the aircraft,
leaving the flight crew with the minimum flightdeck displays and
difficulty controlling the aircraft.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
