SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all MHI RJ Aviation ULC Model
CL–600–2C10 (Regional Jet Series 700,
701 & 702), CL–600–2C11 (Regional Jet
Series 550), CL–600–2D15 (Regional Jet
Series 705), CL–600–2D24 (Regional Jet
Series 900), and CL–600–2E25 (Regional
Jet Series 1000) airplanes. The NPRM
published in the Federal Register on
March 3, 2023 (88 FR 13385). The
NPRM was prompted by AD CF–2022–
43, dated August 9, 2022, issued by
Transport Canada, which is the aviation
authority for Canada (referred to after
this as the MCAI). The MCAI states that
new airworthiness limitations have been
developed.
In the NPRM, the FAA proposed to
require revising the existing
maintenance or inspection program, as
applicable, to incorporate new or more
restrictive airworthiness limitations.
The FAA is issuing this AD to address
an unannunciated loss or low quantity

of fire extinguishing agent in the engine
and auxiliary power unit (APU) fire
extinguishing bottles. This condition, if
not corrected, could result in the
inability to extinguish and suppress an
engine or APU fire.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2023–0422.
Discussion of Final Airworthiness
Directive
Comments
The FAA received comments from
The Air Line Pilots Association,
International (ALPA) who supported the
NPRM without change.
Conclusion
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
reviewed the relevant data and
determined that air safety requires
adopting this AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on this
product. Except for minor editorial
changes, this AD is adopted as proposed
in the NPRM. None of the changes will
increase the economic burden on any
operator.

This service information is reasonably
available because the interested parties
have access to it through their normal

Costs of Compliance
The FAA estimates that this AD
affects 606 airplanes of U.S. registry.
E:\FR\FM\06JNR1.SGM
06JNR1
Federal Register / Vol. 88, No. 108 / Tuesday, June 6, 2023 / Rules and Regulations
The FAA estimates the following costs
to comply with this AD:
The FAA has determined that revising
the 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. Therefore, the agency
estimates the average total cost per
operator to be $7,650 (90 work-hours ×
$85 per work-hour).
ddrumheller on DSK120RN23PROD with RULES1
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.

622R airplanes. The NPRM published in
the Federal Register on February 24,
2023 (88 FR 11827). The NPRM was
prompted by AD 2022–0192, dated
September 23, 2022, issued by EASA,
which is the Technical Agent for the
Member States of the European Union
(EASA AD 2022–0192) (also referred to
as the MCAI). The MCAI states that new
or more restrictive airworthiness
limitations have been developed.
In the NPRM, the FAA explained that
EASA AD 2022–0192 specifies that it
requires certain tasks (limitations)
already in Airbus A300–600 ALS Part 2
DT–ALI, Revision 03, that is required by
EASA AD 2019–0090, dated April 26,
2019 (which corresponds to FAA AD
2019–21–01, Amendment 39–19767 (84
FR 56935, October 24, 2019) (AD 2019–
21–01)), and that incorporation of EASA
AD 2022–0192 invalidates (terminates)
prior instructions for those tasks. The
NPRM therefore proposed to terminate
the limitations required by paragraph (g)
of AD 2019–21–01, for the tasks
identified in the service information
referred to in EASA AD 2022–0192
only, as specified in EASA AD 2022–
0192. The FAA is issuing this AD to
address fatigue cracking, damage, or
corrosion in principal structural
elements, which could result in reduced
structural integrity of the airplane.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all MHI RJ Aviation ULC
Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11
(Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-
600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet
Series 1000) airplanes. The NPRM published in the Federal Register on
March 3, 2023 (88 FR 13385). The NPRM was prompted by AD CF-2022-43,
dated August 9, 2022, issued by Transport Canada, which is the aviation
authority for Canada (referred to after this as the MCAI). The MCAI
states that new airworthiness limitations have been developed.
In the NPRM, the FAA proposed to require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations. The FAA is issuing this AD
to address an unannunciated loss or low quantity of fire extinguishing
agent in the engine and auxiliary power unit (APU) fire extinguishing
bottles. This condition, if not corrected, could result in the
inability to extinguish and suppress an engine or APU fire.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2023-0422.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from The Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
Conclusion
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 reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD to address the unsafe condition on this product.
Except for minor editorial changes, this AD is adopted as proposed in
the NPRM. None of the changes will increase the economic burden on any
operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Task 26-20-00-101, ``Visual Check of the Engine
Fire Extinguishing bottle pressure gauge'' and Task 26-20-00-102,
``Visual Check of the APU Fire Extinguishing bottle pressure gauge,''
of Section 1, ``Certification Maintenance Requirements,'' Subject 1-26,
``Fire Protection,'' of the MHI RJ Model CL-600-2C10, CL-600-2C11, CL-
600-2D15, CL-600-2D24, and CL-600-2E25 Series 550/700/705/900/1000
Airworthiness Limitations, Maintenance Requirements Manual--Part 2,
Volume 1, CSP B-053, Revision 26, dated March 25, 2022. This service
information specifies procedures for new airworthiness limitations for
certification maintenance requirements.
This service information 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 606 airplanes of U.S.
registry.
[[Page 36925]]
The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the 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. Therefore, the
agency estimates the average total cost per operator 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.
