Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2C11 (Regional Jet Series 550) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600- 2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by reports of corrosion on fuel clamshell couplings installed in the fuel tank, and a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require removing and replacing the fuel clamshell couplings on certain airplanes, and revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2021-16, dated April 26,
2021 (TCCA AD CF-2021-16) (also referred to after this as the Mandatory
Continuing Airworthiness Information, or the MCAI), to correct an
unsafe condition for certain MHI RJ Aviation ULC Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional
Jet Series 700, 701 & 702) airplanes, Model CL-600-2C11 (Regional Jet
Series 550) airplanes, Model CL-600-2D15 (Regional Jet Series 705)
airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and
Model CL-600-2E25 (Regional Jet Series 1000) airplanes. You may examine
the MCAI in the AD docket on the internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2022-
0011.
This proposed AD was prompted by reports of corrosion on fuel
clamshell couplings installed in the fuel tank, and a determination
that new or more restrictive airworthiness limitations are necessary.
The FAA is proposing this AD to address corroded fuel clamshell
couplings in the fuel tank, which, if not removed and replaced, could
reduce the ability of the fuel coupling to conduct
[[Page 3717]]
lightning current and possibly lead to arcing and subsequent fuel tank
ignition in the event of a lightning strike. See the MCAI for
additional background information.
Related Service Information Under 1 CFR Part 51
MHI RJ Aviation has issued Service Bulletin 601R-28-068, Revision
A, dated December 21, 2020; and Service Bulletin 670BA-28-041, Revision
B, dated January 27, 2021. This service information describes
procedures for removing and replacing the fuel clamshell couplings.
These documents are distinct because they apply to different airplane
models.
MHI RJ Aviation has also issued Temporary Revision (TR) 2S4-002,
dated September 1, 2021. This service information describes a Critical
Design Configuration Control Limitations (CDCCL) item for bonding of
fuel and vent lines for lightning protection to preclude a spark.
MHI RJ Aviation has also issued the following TRs, which describe
airworthiness limitations for fuel tank systems.
<bullet> TR 2S4-003, dated September 1, 2021; CRJ Series Regional
Jet TR ALI-0741, dated October 13, 2020; and CRJ700/900/1000 Series
Regional Jet TR ALI-0751, dated April 8, 2021, describe a procedure for
removing and replacing self-bonding couplings in the fuel tank.
<bullet> CRJ Series Regional Jet TR ALI-0740, dated October 13,
2020, describes a CDCCL item for bonding of fuel and vent lines for
lightning protection to preclude a spark.
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.
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 and service information 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 these
same type designs.
Proposed Requirements of This NPRM
This proposed AD would require removing and replacing the fuel
clamshell couplings on certain airplanes and revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations.
This proposed AD would require revisions to certain operator
maintenance documents to include new actions (e.g., inspections) and
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 according to
paragraph (m)(1) of this proposed AD.
Differences Between This Proposed AD and the MCAI or Service
Information
The MCAI specifies to revise the CDCCL Items as introduced by
Bombardier CL-600-2B19 TR 2D-009, dated October 24, 2020, in Appendix
D--Fuel Systems Limitations of Part 2, Airworthiness Requirements, of
the MHI RJ Maintenance Requirements Manual (MRM). This proposed AD does
not require this action because the TR references Appendix D--Fuel
Systems Limitations of Part 2, Airworthiness Requirements, of the MHI
RJ MRM, which is not applicable to U.S. airplanes. As a result, this
proposed AD would require that the information specified in MHI RJ TR
2S4-002, dated September 1, 2021, is incorporated into Supplement 4--
FAA Fuel System Limitations of Part 2, Airworthiness Requirements, of
the MHI RJ MRM as required by paragraph (h)(1) of this proposed AD. MHI
RJ TR 2S4-002, dated September 1, 2021, addresses the unsafe condition
with references that apply to U.S. airplanes and provides the same or
better level of safety.
The MCAI also specifies to incorporate the new Fuel System
Limitation Task 28-23-00-605 as introduced by Bombardier CL-600-2B19 TR
2D-008, dated October 24, 2020; and to revise the Task Description
Effectivity as amended by Bombardier CL-600-2B19 TR 2D-010, dated April
8, 2021; in Appendix D--Fuel Systems Limitations of Part 2,
Airworthiness Requirements, of the MHI RJ MRM. This proposed AD does
not require these actions because these TRs also reference Appendix D--
Fuel Systems Limitations of Part 2, Airworthiness Requirements, of the
MHI RJ MRM, which is not applicable to U.S. airplanes. As a result,
this proposed AD would require that the information specified in MHI RJ
TR 2S4-003, dated September 1, 2021, is incorporated into Supplement
4--FAA Fuel System Limitations of Part 2, Airworthiness Requirements,
of the MHI RJ MRM, as specified in paragraph (h)(2) of this proposed
AD. MHI RJ TR 2S4-003, dated September 1, 2021, addresses the unsafe
condition with references that apply to U.S. airplanes and provides the
same or better level of safety.
Costs of Compliance
The FAA estimates that this proposed AD affects 914 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 21 work-hours x $85 per Up to $5,837.......... Up to $7,622.......... Up to $6,966,508.
hour = $1,785.
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for revising the maintenance/inspection program.
The FAA has determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although the
FAA recognizes that this number may vary from operator to operator. In
the past, the FAA has estimated that this action takes 1 work-hour per
airplane. 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 FAA estimates the total cost per operator to be $7,650
(90 work-hours x $85 per work-hour).
According to the manufacturer, some or all of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected individuals. The FAA does not control warranty
coverage for affected individuals. As a result, the FAA has
[[Page 3718]]
included all known costs in the cost estimate.
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
