Abstract
The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440); 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. This AD was prompted by a determination that aircraft maintenance manual (AMM) tasks and certification maintenance requirement (CMR) tasks are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive AMM and CMR tasks. The FAA is issuing this AD to address the unsafe condition on these products.

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-600-2B19 (Regional Jet Series 100 & 440); 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 February 16, 2023 (88 FR
10060). The NPRM was prompted by AD CF-2022-32, dated June 13, 2022,
issued by Transport Canada, which is the aviation authority for Canada
(referred to after this as the MCAI). The MCAI states that it was
discovered that the 10-year (120-month) periodic hydrostatic tests of
the engine and auxiliary power unit (APU) fire extinguishing bottles on
Model CL-600-2B19 airplanes and of the engine, APU, and cargo
compartment fire extinguishing bottles for Model CL-600-2C10, CL-600-
2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 airplanes were not
performed. This could mean that the functional test of the pressure
switch, which should be performed as part of the hydrostatic tests, may
have been omitted on several airplanes in service. Failure to perform
the pressure switch test and the 10-year overhaul or restoration of the
FIREX bottles could result in a dormant loss of fire extinguishing
capability.
In the NPRM, the FAA proposed to require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive AMM and CMR tasks. The FAA is issuing this AD to
address undetected loss of fire extinguishing capability for the
engine, APU, or cargo compartment. The unsafe condition, if not
addressed, could result in an inability to put out a fire in the
engine, APU, or cargo compartment area.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-0167.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from 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, considered the
comment received, 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 Bombardier Temporary Revisions 2A-73 and 2A-74,
both dated June 5, 2020. This service information specifies new or more
restrictive CMR tasks.
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 1,114 airplanes of U.S.
registry. 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
[[Page 32627]]
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.

effective date of this AD, revise the existing maintenance or
inspection program, as applicable, to incorporate the information
specified in Bombardier Temporary Revisions 2A-73 and 2A-74, both
dated June 5, 2020. The initial compliance time for doing the tasks
is at the applicable times specified in Bombardier Temporary
Revisions 2A-73 and 2A-74, both dated June 5, 2020, or within 60
days after the effective date of this AD, whichever occurs later.

this AD.
(i) If a restoration (previously called a hydrostatic test) of
any cargo compartment fire extinguisher bottle was accomplished on
or before June 5, 2014, do the applicable maintenance task on that
bottle within 48 months after the effective date of this AD.
(ii) If a restoration (previously called a hydrostatic test) of
any cargo compartment fire extinguisher bottle was accomplished
after June 5, 2014, do the applicable maintenance task on that
bottle within 10 years after the most recent restoration was
accomplished.

(i) No Alternative Actions or Intervals
After the existing maintenance or inspection program has been
revised as required by paragraphs (g) and (h) of this AD, no
alternative actions (e.g., inspections) or intervals may be used
unless the actions and intervals are approved as an alternative
method of compliance (AMOC) in accordance with the procedures
