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: All DHC–8 Series 400 aircraft have had a spoiler fuselage cable disconnect sensing system installed in production. Subsequently it was discovered that, in the event of a spoiler fuselage cable disconnect, only the ROLL SPLR INBD HYD caution light will be illuminated until the aircraft speed decreases below 165 kts [knots], at which time the ROLL SPLR OUTBD HYD caution light will also be illuminated. In the event of a spoiler fuselage cable disconnect in association with the existing indications described above, the reduction in roll authority could result in increased pilot workload during approach and landing. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 This AD becomes effective November 3, 2008. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 3, 2008. ADDRESSES: You may examine the AD docket on the Internet at https:// 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.

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 July 2, 2008 (73 FR 37896). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: All DHC–8 Series 400 aircraft have had a spoiler fuselage cable disconnect sensing system installed in production. Subsequently it was discovered that, in the event of a spoiler fuselage cable disconnect, only the ROLL SPLR INBD HYD caution light will be illuminated until the aircraft speed decreases below 165 kts [knots], at which time the ROLL SPLR OUTBD HYD caution light will also be illuminated. In the event of a spoiler fuselage cable disconnect in association with the existing indications described above, the reduction in roll authority could result in increased pilot workload during approach and landing. Modsums 4–110066 and 4–126356 (each applicable to a different batch of aircraft serial numbers) have been issued to rework the sensing circuit caution light indication to ensure that it is consistent for spoiler fuselage cable disconnects above and below 165 kts. Modsum 4–126356 has been installed in production on aircraft serial numbers 4130 and subsequent. You may obtain further information by examining the MCAI in the AD docket. E:\FR\FM\29SER1.SGM 29SER1 Federal Register / Vol. 73, No. 189 / Monday, September 29, 2008 / Rules and Regulations 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. jlentini on PROD1PC65 with RULES Costs of Compliance We estimate that this AD will affect about 20 products of U.S. registry. We also estimate that it will take about 10 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $2,339 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $62,780, or $3,139 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 VerDate Aug<31>2005 16:29 Sep 26, 2008 Jkt 214001 56469 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. 2008–19–07 Bombardier, Inc. (Formerly de Havilland, Inc.): Amendment 39–15674. Docket No. FAA–2008–0730; Directorate Identifier 2008–NM–055–AD. 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.

and DHC-8-402 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:

    All DHC-8 Series 400 aircraft have had a spoiler fuselage cable 
disconnect sensing system installed in production. Subsequently it 
was discovered that, in the event of a spoiler fuselage cable 
disconnect, only the ROLL SPLR INBD HYD caution light will be 
illuminated until the aircraft speed decreases below 165 kts 
[knots], at which time the ROLL SPLR OUTBD HYD caution light will 
also be illuminated. In the event of a spoiler fuselage cable 
disconnect in association with the existing indications described 
above, the reduction in roll authority could result in increased 
pilot workload during approach and landing.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective November 3, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 3, 
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 July 2, 2008 (73 FR 
37896). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    All DHC-8 Series 400 aircraft have had a spoiler fuselage cable 
disconnect sensing system installed in production. Subsequently it 
was discovered that, in the event of a spoiler fuselage cable 
disconnect, only the ROLL SPLR INBD HYD caution light will be 
illuminated until the aircraft speed decreases below 165 kts 
[knots], at which time the ROLL SPLR OUTBD HYD caution light will 
also be illuminated. In the event of a spoiler fuselage cable 
disconnect in association with the existing indications described 
above, the reduction in roll authority could result in increased 
pilot workload during approach and landing.
    Modsums 4-110066 and 4-126356 (each applicable to a different 
batch of aircraft serial numbers) have been issued to rework the 
sensing circuit caution light indication to ensure that it is 
consistent for spoiler fuselage cable disconnects above and below 
165 kts. Modsum 4-126356 has been installed in production on 
aircraft serial numbers 4130 and subsequent.

You may obtain further information by examining the MCAI in the AD 
docket.

[[Page 56469]]

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 20 products of U.S. 
registry. We also estimate that it will take about 10 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $80 per work-hour. Required parts will cost about $2,339 
per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $62,780, or $3,139 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 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

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

2008-19-07 Bombardier, Inc. (Formerly de Havilland, Inc.): Amendment 
39-15674. Docket No. FAA-2008-0730; Directorate Identifier 2008-NM-
055-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective November 
3, 2008.

Affected ADs

    (b) None.

Applicability

    (c) Bombardier Model DHC-8-400, DHC-8-401 and DHC-8-402 
airplanes, serial numbers 4003, 4004, 4006, and 4008 through 4129, 
certificated in any category.

Subject

    (d) Air Transport Association (ATA) of America Code 27: Flight 
Controls

Reason

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

    All DHC-8 Series 400 aircraft have had a spoiler fuselage cable 
disconnect sensing system installed in production. Subsequently it 
was discovered that, in the event of a spoiler fuselage cable 
disconnect, only the ROLL SPLR INBD HYD caution light will be 
illuminated until the aircraft speed decreases below 165 kts 
[knots], at which time the ROLL SPLR OUTBD HYD caution light will 
also be illuminated. In the event of a spoiler fuselage cable 
disconnect in association with the existing indications described 
above, the reduction in roll authority could result in increased 
pilot workload during approach and landing.
    Modsums 4-110066 and 4-126356 (each applicable to a different 
batch of aircraft serial numbers) have been issued to rework the 
sensing circuit caution light indication to ensure that it is 
consistent for spoiler fuselage cable disconnects above and below 
165 kts. Modsum 4-126356 has been installed in production on 
aircraft serial numbers 4130 and subsequent.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) For airplanes with serial numbers 4003, 4004, 4006, and 4008 
through 4094: Within 6,000 flight hours after the effective date of 
this AD, modify the spoiler cable disconnect sensing circuit by 
incorporating Modsum 4-110066 in accordance with Bombardier Service 
Bulletin 84-27-33, dated June 6, 2007.
    (2) For airplanes with serial numbers 4095 through 4129: Within 
6,000 flight hours after the effective date of this AD, modify the 
spoiler cable disconnect sensing circuit by incorporating Modsum 4-
126356 in accordance with Bombardier Service Bulletin 84-27-28, 
Revision B, dated September 25, 2007.
    (3) Installations of Modsum 4-126356 accomplished before the 
effective date of this AD according to Bombardier Service Bulletin 
84-27-28, dated October 2, 2006; or Revision A, dated April 30, 
2007; are considered acceptable for compliance with the 
corresponding action specified in this AD.
