SUPPLEMENTARY INFORMATION: 14 CFR Part 39 Discussion [Docket No. FAA–2009–0689; Directorate Identifier 2009–NM–092–AD; Amendment 39–16081; AD 2009–23–09] 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 5, 2009 (74 FR 38999). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: DEPARTMENT OF TRANSPORTATION RIN 2120–AA64 Airworthiness Directives; Bombardier Model CL–600–1A11 (CL–600), CL– 600–2A12 (CL–601), CL–600–2B16 (CL– 601–3A) Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: 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: WReier-Aviles on DSKGBLS3C1PROD with RULES Two cases have been reported in which the ADG [air driven generator] has failed to power the essential bus following in-flight deployment as part of its periodic operational check. Subsequent inspection revealed that the ADG power feeder harness wire (* * * [aromatic polyimide]) had chafed on the backshell of its own connector (P1XC), resulting in a short circuit, wire damage and disconnection of the wire from the ADG. Coupled with a dual generator failure, such a disconnection would result in the loss of emergency power to critical systems, with a consequent adverse effect on the controllability of the aircraft. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective December 14, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 14, 2009. ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC. FOR FURTHER INFORMATION CONTACT: Wing Chan, Aerospace Engineer, Avionics and Flight Test Branch, ANE– 172, FAA, New York Aircraft Certification Office, 1600 Stewart Avenue, Suite 410, Westbury, New York VerDate Nov<24>2008 15:01 Nov 06, 2009 Jkt 220001 Two cases have been reported in which the ADG [air driven generator] has failed to power the essential bus following in-flight deployment as part of its periodic operational check. Subsequent inspection revealed that the ADG power feeder harness wire (* * * [aromatic polyimide]) had chafed on the backshell of its own connector (P1XC), resulting in a short circuit, wire damage and disconnection of the wire from the ADG. Coupled with a dual generator failure, such a disconnection would result in the loss of emergency power to critical systems, with a consequent adverse effect on the controllability of the aircraft. This directive mandates an inspection to determine the type of wire in the installed ADG power feeder harness. If the wires are a * * * [aromatic polyimide] type, the ADG power feeder harness is to be replaced with one incorporating * * * [non-aromatic polyimide] type wire. 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 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. PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 57577 Costs of Compliance We estimate that this AD will affect about 203 products of U.S. registry. We also estimate that it will take about 2 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 $32,480, or $160 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.

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:

    Two cases have been reported in which the ADG [air driven 
generator] has failed to power the essential bus following in-flight 
deployment as part of its periodic operational check. Subsequent 
inspection revealed that the ADG power feeder harness wire (* * * 
[aromatic polyimide]) had chafed on the backshell of its own 
connector (P1XC), resulting in a short circuit, wire damage and 
disconnection of the wire from the ADG. Coupled with a dual 
generator failure, such a disconnection would result in the loss of 
emergency power to critical systems, with a consequent adverse 
effect on the controllability of the aircraft.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective December 14, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 14,

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 5, 2009 (74 
FR 38999). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Two cases have been reported in which the ADG [air driven 
generator] has failed to power the essential bus following in-flight 
deployment as part of its periodic operational check. Subsequent 
inspection revealed that the ADG power feeder harness wire (* * * 
[aromatic polyimide]) had chafed on the backshell of its own 
connector (P1XC), resulting in a short circuit, wire damage and 
disconnection of the wire from the ADG. Coupled with a dual 
generator failure, such a disconnection would result in the loss of 
emergency power to critical systems, with a consequent adverse 
effect on the controllability of the aircraft.
    This directive mandates an inspection to determine the type of 
wire in the installed ADG power feeder harness. If the wires are a * 
* * [aromatic polyimide] type, the ADG power feeder harness is to be 
replaced with one incorporating * * * [non-aromatic polyimide] type 
wire.

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 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 203 products of U.S. 
registry. We also estimate that it will take about 2 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 $32,480, or $160 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

Docket No. FAA-2009-0689; Directorate Identifier 2009-NM-092-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
14, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to the airplanes, certificated in any 
category, as identified in paragraphs (c)(1), (c)(2), and (c)(3) of 
this AD.
    (1) Bombardier Model CL-600-1A11 (CL-600) airplanes, serial 
numbers 1004 through 1085 inclusive.
    (2) Bombardier Model CL-600-2A12 (CL-601) airplanes, serial 
numbers 3001 through 3066 inclusive.
    (3) Bombardier Model CL-600-2B16 (CL-601-3A) airplanes, serial 
numbers 5001 through 5131 inclusive.

Subject

    (d) Air Transport Association (ATA) of America Code 24: 
Electrical power.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    Two cases have been reported in which the ADG [air driven 
generator] has failed to power the essential bus following in-flight 
deployment as part of its periodic operational check. Subsequent 
inspection revealed that the ADG power feeder harness wire (* * * 
[aromatic polyimide]) had chafed on the backshell of its own 
connector (P1XC), resulting in a short circuit, wire damage and 
disconnection of the wire from the ADG. Coupled with a dual 
generator failure, such a disconnection would result in the loss of 
emergency power to critical systems, with a consequent adverse 
effect on the controllability of the aircraft.
    This directive mandates an inspection to determine the type of 
wire in the installed ADG power feeder harness. If the wires are a * 
* * [aromatic polyimide] type, the ADG power feeder harness is to be 
replaced with one incorporating * * * [non-aromatic polyimide] type 
wire.

Actions and Compliance

    (f) Unless already done, within 26 months after the effective 
date of this AD, inspect the ADG power feeder harness to determine 
the wire type, in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 600-0737 or 601-0591, both dated July 
23, 2007, as applicable. A review of airplane maintenance records is 
acceptable in lieu of this inspection if the wire type of the power 
feeder harness can be conclusively determined from that review. If 
the wire type is determined to be aromatic polyimide, replace the 
ADG power feeder harness, before further flight, in accordance with 
Part B of the Accomplishment Instructions of Bombardier Service 
Bulletin 600-0737 or 601-0591, both dated July 23, 2007, as 
applicable.
