Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2021-13, dated April 1,
2021 (TCCA AD CF-2021-13) (also referred to after this as the Mandatory
Continuing Airworthiness Information, or the MCAI), to correct an
unsafe condition for Bombardier, Inc., Model CL-600-1A11 (600), CL-600-
2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants)
airplanes, equipped with any Cox & Co. 3043 or 3044 series (potable
water-line) ribbon heater. You may examine the MCAI in the AD docket at
<a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No.
FAA-2022-0090.
This proposed AD was prompted by a report of smoke in the aft cabin
during a maintenance activity, which an investigation determined was
caused by a faulty drain line ribbon heater. The ribbon heater lead
wires were found to have been installed with the lead wire termination
reversed, which, in combination with a ribbon heater ground fault, led
to a continuous ribbon heater heating condition. The FAA is proposing
this AD to address faulty potable water-line ribbon heaters, which, if
not corrected, could lead to an onboard fire. See the MCAI for
additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 601-0644, Revision 1, dated
January 29, 2019, and Service Bulletin 604-30-007, Revision 1, dated
January 29, 2019. This service information describes procedures for a
general visual inspection of all affected potable water-line ribbon
heater installations for any discrepancy and applicable corrective
actions and other specified actions. Discrepancies include
discoloration, blistering or cracking of insulation, signs of wear, or
heat damage. Corrective actions include replacement of discrepant
insulation and ribbon heaters. Other specified actions include
identifying the potable water-line ribbon heater pigtail wire
configuration, installing a fuse to the ribbon heater power lead, and
testing the potable water-line heater system of each ribbon heater.
These documents are distinct since they apply to different airplane
models. 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
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 the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
the unsafe condition described previously is likely to exist or develop
on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 585 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 30 work-hours x $85 per hour = Up $268 Up to $2,818.............. Up to $1,648,530.
to $2,550.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action 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 this on-condition action:
[[Page 7058]]
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
Up to 30 work-hours x $85 per hour Up to $39,552 *..... $42,102
= $2,550.
------------------------------------------------------------------------
* The parts cost for a single potable water-line ribbon heater and
associated material is $4,944. The estimated cost above assumes the
worst case scenario of replacing all eight ribbon heaters on an
airplane configured with eight ribbon heaters.
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) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
