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 https://www.regulations.gov
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
7057
describes procedures for a general visual
inspection of all affected potable waterline 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:

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.

AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
Viking Air Limited (Viking) (type
certificate previously held by
Bombardier Inc. and de Havilland, Inc.)
Model DHC–3 airplanes. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as corrosion, wear, and
fatigue-related degradation in aging
aircraft. This proposed AD would
require establishing a corrosion
prevention and control program to
identify and correct corrosion and
cracking. This proposed AD would also
require completing all of the initial tasks
identified in the program and reporting
corrosion findings to Viking. The FAA
is proposing this AD to address the
unsafe condition on these products.
DATES: The FAA must receive comments
on this proposed AD by March 25, 2022.
ADDRESSES: You may send comments by
any of the following methods:

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
https://www.regulations.gov 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.
