RIN 2120–AA64 Discussion BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 Airworthiness Directives; Bombardier Model DHC–8–400 Series Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC–8–400 series airplanes. This AD requires a one-time inspection of the fuel and hydraulic tubes, and corrective actions if necessary. This AD also requires modifying fairlead plate assemblies. This AD results from reports of chafing between fuel and hydraulic tubes and the fairlead plate where the tubes pass through the firewall. We are issuing this AD to prevent chafing of the fuel and hydraulic tubes, which could lead to fuel and/or hydraulic fluid leakage in the engine nacelle area and consequent fire or explosion. DATES: This AD becomes effective October 14, 2005. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of October 14, 2005. ADDRESSES: You may examine the AD docket on the Internet at http:// dms.dot.gov or in person at the Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street SW., Nassif Building, room PL–401, Washington, DC. Contact Bombardier, Inc., Bombardier Regional Aircraft Division, 123 Garratt Boulevard, Downsview, Ontario M3K 1Y5, Canada, for service information identified in this AD. FOR FURTHER INFORMATION CONTACT: Richard Fiesel, Aerospace Engineer, Airframe and Propulsion Branch, ANE– 171, FAA, New York Aircraft Certification Office, 1600 Stewart Avenue, suite 410, Westbury, New York PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Bombardier Model DHC–8–400 series airplanes. That NPRM was published in the Federal Register on June 14, 2005 (70 FR 34409). That NPRM proposed to require a onetime inspection of the fuel and hydraulic tubes, and corrective actions if necessary. That NPRM also proposed to require modifying fairlead plate assemblies. Explanation of Change to Applicability We have revised the applicability of the proposed AD to identify model designations as published in the most recent type certificate data sheet for the affected models. Comments We provided the public the opportunity to participate in the development of this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance This AD will affect about 18 airplanes of U.S. registry. The actions will take about 4 work hours per airplane, at an average labor rate of $65 per work hour. Required parts will cost about $200 per airplane. Based on these figures, the estimated cost of the AD for U.S. operators is $8,280, or $460 per airplane. E:\FR\FM\09SER1.SGM 09SER1 Federal Register / Vol. 70, No. 174 / Friday, September 9, 2005 / Rules and Regulations 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 have 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) Is not a ‘‘significant rule’’ under 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

Small Business Regulatory Enforcement Fairness Act The Small Business Regulatory Enforcement Fairness Act (SBREFA) of 1996 requires FAA to comply with small entity requests for information or advice about compliance with statutes and regulations within its jurisdiction. Therefore, any small entity that has a question regarding this document may contact their local FAA official, or the person listed under FOR FURTHER INFORMATION CONTACT. You can find out more about SBRFA on the Internet at our site, http://www.faa.gov/avr/arm/ sbrefa.cfm. Authority for This Action The Department of Transportation (DOT) has the responsibility, under the laws of the United States, to develop transportation policies and programs that contribute to providing fast, safe, efficient, and convenient transportation (49 U.S.C. 101). The Federal Aviation Administration (FAA) is an agency of DOT. The Administrator of the FAA has general authority to issue rules regarding aviation safety (49 U.S.C. 106(g) and 44701). When an individual is found to be qualified for, and physically able to perform, certain duties, including those associated with flying and navigating an aircraft, the FAA issues an airman certificate. The airman certificate must specify the capacity in which the holder of the certificate may serve with respect to an aircraft (49 U.S.C. 44703). It is relevant to this rulemaking to also point out that, in carrying out their duties, the Secretary of Transportation and the Administrator of the FAA must act consistently with obligations of the United States Government under an international agreement (49 U.S.C. 40105). This action establishes a compliance date for the SIC pilot type rating and associated qualifying procedures. The PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 compliance date is the date that those affected by a rule must begin to follow it. In the preamble to the amendments adopted on August 4, 2005, the FAA found the amendments to be a reasonable and necessary exercise of our rulemaking authority and obligations. We now find that establishing a compliance date, by extension, also is a reasonable and necessary exercise of our rulemaking authority and obligations. Background On August 4, 2005, the FAA amended its regulations to provide for issuance of a pilot type rating for SIC privileges when a person completes the SIC pilot familiarization training set forth under 14 CFR 61.55(b), an FAA-approved SIC training curriculum under 14 CFR parts 121 or 135, or a proficiency check under 14 CFR part 125. See 70 FR 45263. The amendments adopted on August 4, 2005, are based on a notice of proposed rulemaking (NPRM) published in the Federal Register on November 16, 2004. See 69 FR 67258. The amendments require pilots acting as second in command and who plan to fly outside U.S. airspace and land in foreign countries to obtain the SIC pilot type rating. The amendments also establish two procedures for obtaining the SIC pilot type rating. The effective date of the amendments is September 6, 2005. The effective date is the date the amendments affect the current Code of Federal Regulations (CFR). Establishing a Compliance Date Although we received two comments on the November NPRM asking for 6 to 18 months for pilots to comply with the requirement to obtain a SIC pilot type rating,1 the FAA believed that 30 days (by September 6, 2005) was sufficient time. Additionally, the FAA has been put on notice by several foreign civil aviation authorities that they intend to begin enforcing the type-rating requirement; thus we believe that the sooner the rule becomes effective and U.S. pilots receive their SIC pilot type ratings, the sooner U.S. flight crews will be able to operate internationally unimpeded. The Agency, however, has reevaluated the time necessary for pilots to comply with the amendments. Since 1 The National Air Carrier Association recommended that the FAA provide a minimum of six months from issuing the final rule to full implementation and revision of its ICAO difference because its member airlines need to provide time for the initial processing of the several hundred thousand applications required for this SIC pilot type rating. The representative of American Airlines requested 18 months to complete the initial certification process for its initial 3,066 pilots that are not currently type rated. E:\FR\FM\09SER1.SGM 09SER1

Airworthiness Directives; Bombardier Model DHC-8-400 Series 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier Model DHC-8-400 series airplanes. This AD requires a 
one-time inspection of the fuel and hydraulic tubes, and corrective 
actions if necessary. This AD also requires modifying fairlead plate 
assemblies. This AD results from reports of chafing between fuel and 
hydraulic tubes and the fairlead plate where the tubes pass through the 
firewall. We are issuing this AD to prevent chafing of the fuel and 
hydraulic tubes, which could lead to fuel and/or hydraulic fluid 
leakage in the engine nacelle area and consequent fire or explosion.

DATES: This AD becomes effective October 14, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of October 14, 
2005.

ADDRESSES: You may examine the AD docket on the Internet at http://
dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street SW., Nassif Building, 
room PL-401, Washington, DC.
    Contact Bombardier, Inc., Bombardier Regional Aircraft Division,

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Bombardier 
Model DHC-8-400 series airplanes. That NPRM was published in the 
Federal Register on June 14, 2005 (70 FR 34409). That NPRM proposed to 
require a one-time inspection of the fuel and hydraulic tubes, and 
corrective actions if necessary. That NPRM also proposed to require 
modifying fairlead plate assemblies.

Explanation of Change to Applicability

    We have revised the applicability of the proposed AD to identify 
model designations as published in the most recent type certificate 
data sheet for the affected models.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

Costs of Compliance

    This AD will affect about 18 airplanes of U.S. registry. The 
actions will take about 4 work hours per airplane, at an average labor 
rate of $65 per work hour. Required parts will cost about $200 per 
airplane. Based on these figures, the estimated cost of the AD for U.S. 
operators is $8,280, or $460 per airplane.

[[Page 53559]]

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 have 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
