RIN 2120-AA64
Airworthiness Directives; Bombardier Model CL-600-2C10 (Regional
Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), and
CL-600-2D24 (Regional Jet Series 900) Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. 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:
There have been several incidents of shorting and sparks due to
de-icing fluid ingress into the cockpit of CL-600-2C10 and CL-600-
2D24 aircraft. De-icing fluid can enter between the windshields and
side windows, leading to possible damage to the electrical
components and wires as it comes into contact with cockpit
floodlight electrical connections.
De-icing fluid in contact with cockpit floodlight electrical
connections can result in possible arcing and fire. The proposed AD
would require actions that are intended to address the unsafe condition
described in the MCAI.
DATES: We must receive comments on this proposed AD by September 25,
2008.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2008-19, dated May 8, 2008 (referred to after this as ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:
There have been several incidents of shorting and sparks due to
de-icing fluid ingress into the cockpit of CL-600-2C10 and CL-600-
2D24 aircraft. De-icing fluid can enter between the windshields and
side windows, leading to possible damage to the electrical
components and wires as it comes into contact with cockpit
floodlight electrical connections.
De-icing fluid in contact with cockpit floodlight electrical
connections can result in possible arcing and fire. The actions to
address the unsafe condition include performing a leak test, applying
sealant between the windshields and side windows, and doing related
investigative and corrective actions. The related investigative action
is performing a leak test after applying sealant. The related
corrective action is contacting Bombardier for repair instructions and
doing the repair. You may obtain further information by examining the
MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Alert Service Bulletin A670BA-56-002,
Revision A, dated February 26, 2008. The actions described in this
service information are intended to correct the unsafe condition
identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 254 products of U.S. registry. We also estimate that
it would take about 4 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Based on these figures, we estimate the cost of the
[[Page 50255]]
proposed AD on U.S. operators to be $81,280, or $320 per product.
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.
We are 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
We 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. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2008-0911;
Directorate Identifier 2008-NM-115-AD.
Comments Due Date
(a) We must receive comments by September 25, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier Model CL-600-2C10 (Regional
Jet Series 700, 701 & 702) airplanes, serial numbers 10003 through
10216 inclusive; and Model CL-600-2D15 (Regional Jet Series 705) and
CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers
15001 through 15040 inclusive; certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 56: Windows.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
There have been several incidents of shorting and sparks due to
de-icing fluid ingress into the cockpit of CL-600-2C10 and CL-600-
2D24 aircraft. De-icing fluid can enter between the windshields and
side windows, leading to possible damage to the electrical
components and wires as it comes into contact with cockpit
floodlight electrical connections.
De-icing fluid in contact with cockpit floodlight electrical
connections can result in possible arcing and fire. The actions to
address the unsafe condition include performing a leak test,
applying sealant between the windshields and side windows, and doing
related investigative and corrective actions. The related
investigative action is performing a leak test after applying
sealant. The related corrective action is contacting Bombardier for
repair instructions and doing the repair.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 450 flight hours after the effective date of this AD:
Perform a leak test in accordance with Part A of the Accomplishment
Instructions of Bombardier Alert Service Bulletin A670BA-56-002,
Revision A, dated February 26, 2008.
(2) If leakage is detected in the leak test performed in
accordance with paragraph (f)(1) of this AD: Prior to further
flight, apply sealant between the windshields and side windows and
do all applicable related investigative and corrective actions in
accordance with Part B of the Accomplishment Instructions of
Bombardier Alert Service Bulletin A670BA-56-002, Revision A, dated
February 26, 2008. Do all applicable related investigative and
corrective actions before further flight.
(3) If there is no leakage detected in the leak test performed
in accordance with paragraph (f)(1) of this AD: Within 6 months or
