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 certain Bombardier,
Inc., Model CL-600-2B16 (604 Variant) airplanes. The NPRM published in
the Federal Register on March 21, 2024 (89 FR 20141). The NPRM was
prompted by AD CF-2023-55, dated July 18, 2023, issued by Transport
Canada, which is the aviation authority for Canada (referred to after
this as the MCAI). The MCAI states that during airplane refueling, a
spark was seen when the fuel cap chain contacted one of the fuel
scupper bolts. An inspection was performed and one of the fourteen
bolts that surround the fuel inlet was found touching an electrical
wire behind the scupper. Due to vibrations during flight, the bolt
damaged the wire insulation and when the bolt was grounded to the
airframe a spark was generated.
In the NPRM, the FAA proposed to require inspecting the electrical
wires attached to the airplane connector located behind the fuel
scupper for damage, and all applicable related investigative and
corrective actions. The FAA is issuing this AD to address
[[Page 57074]]
damaged wire insulation, which could lead to electrical sparks during
refueling and possibly result in a fire.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-0467.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
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 Bombardier Service Bulletin 605-28-014, dated May
10, 2023; and Bombardier Service Bulletin 650-28-003, dated May 10,
2023. This service information specifies procedures for inspecting the
electrical wires attached to the J274 connector (i.e., the airplane
connector located behind the fuel scupper) for damage (i.e., core of
the electrical wire exposed, or damage such as black soot to the
insulation with no core exposure), and applicable related investigative
and corrective actions. The related investigative action includes
inspecting the fuel scupper for damage (i.e., arcing or pitting marks
directly or indirectly induced by the wire chaffed on the scupper bolt
and the surrounding area). The corrective actions include repairing any
damaged fuel scupper, repairing or replacing any damaged electrical
wire, and reinstalling the fuel scupper without a certain attachment
bolt. These documents are distinct since they apply to different
configurations of the airplane.
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 163 airplanes of U.S.
registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255........................... $0 $255 $41,565
----------------------------------------------------------------------------------------------------------------
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 these on-condition actions:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340 *...................................... ** $0 $340
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost estimates for the on-condition scupper
repair specified in this AD.
** The FAA has received no definitive data on which to base the parts cost for the electrical wire replacement
specified in this AD.
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.
