ACTION: Final rule. AGENCY: 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: SUMMARY: 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. PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 This AD becomes effective December 30, 2008.

SUPPLEMENTARY INFORMATION: DATES: 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 E:\FR\FM\25NOR1.SGM 25NOR1 Federal Register / Vol. 73, No. 228 / Tuesday, November 25, 2008 / Rules and Regulations 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. erowe on PROD1PC63 with RULES 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. VerDate Aug<31>2005 14:39 Nov 24, 2008 Jkt 217001 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 https:// 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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing Model 757 series airplanes. That NPRM was published in the Federal Register on December 6, 2007 (72 FR 68764). That NPRM proposed to require sealing the fasteners on the front and rear spars inside the left and right main fuel tanks and on the lower panel of the center fuel tank. That NPRM also proposed to require inspections of the wire bundle support installations to verify if certain clamps are installed and if Teflon sleeving covers the wire bundles inside the left and right equipment cooling system bays, on the left and right rear spars, and on the left and right front spars; and corrective actions if necessary. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received from the four commenters. Request for Justification of the NPRM Northwest Airlines (NWA) has no objection to the intent of the NPRM, but it states it is not clear that we have shown that the probability of a fuel tank explosion due to unsealed fuel tank fasteners reaches the threshold for justifying the proposed modification. NWA requests that we provide more detail regarding the risk and benefit of the NPRM. We agree to provide clarification. The unsafe condition encompassed the scenario of single failures (for example, a wire bundle clamp failure that could result in wire bundle contact with the fuel tank causing an ignition source internal to the tank) that place an airplane at risk of a fuel tank explosion.

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 https://
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

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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2008-23-18 Bombardier, Inc. (Formerly Canadair): Amendment 39-15739. 
Docket No. FAA-2008-0911; Directorate Identifier 2008-NM-115-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
30, 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 
2,000 flight hours after the effective date of this AD, whichever 
comes first, apply sealant between the windshields and side windows 
and do all applicable related investigative and corrective actions 
before further flight 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.
    (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 
in accordance with Bombardier Alert Service Bulletin A670BA-56-002, 
dated January 7, 2008.
