Amendment 39-15739; AD 2008-23-18]

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), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This 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. We are issuing this
AD to require actions to correct the unsafe condition on these
products.
DATES: This AD becomes effective December 30, 2008.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of December 30,
2008.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on August 26, 2008 (73
FR 50254). That NPRM proposed 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.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the
[[Page 71533]]
public interest require adopting the AD as proposed.
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 required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect about 254 products of U.S.
registry. We also estimate that it will take about 4 work-hours per
product to comply with the basic requirements of this AD. The average
labor rate is $80 per work-hour. Based on these figures, we estimate
the cost of this AD to the 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 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 this AD:
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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

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.

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.
(4) A leak test and application of sealant are also acceptable
for compliance with the requirements of paragraphs (f)(1), (f)(2),
and (f)(3) of this AD if done before the effective date of this AD
