SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 with an AD for certain Gulfstream Aerospace LP Model Gulfstream 100 airplanes; and Model Astra SPX and 1125 Westwind Astra series airplanes. That action, published in the Federal Register on October 4, 2004 (69 FR 59147), proposed to require adjusting the ground contact switches of the main landing gear. Comments We provided the public the opportunity to participate in the development of this AD. No comments have been submitted on the proposed AD 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 as proposed. Costs of Compliance This AD will affect about 106 airplanes of U.S. registry. The actions will take about 3 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $20,670, or $195 per airplane. 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 VerDate jul<14>2003 18:52 Jan 05, 2005 Jkt 205001 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.

Plain language information: Marcia Walters, marcia.walters@faa.gov. SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the Federal Aviation Regulations (14 CFR Part 39) with an AD to supersede AD 99–01–17, amendment 39–10985 (64 FR 1118, January 8, 1999). The existing AD applies to certain Airbus Model A320 series airplanes. The proposed AD was published in the Federal Register on August 5, 2004 (69 FR 47393), to require reducing the compliance threshold and repetitive intervals for the inspections required by the existing AD. The proposed AD also provides for an optional terminating action for the repetitive inspections. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment submitted on the proposed AD. The commenter supports the proposed AD. Clarification of Certain Wording in Preamble of Proposed AD For clarification, we are explaining an inadvertent error in certain wording in the preamble of the proposed AD, which differed from the AD requirements for the optional terminating action specified in paragraph (h) of the proposed AD. In the Summary, Relevant Service Information, and FAA’s Determination and Requirements of the proposed AD sections, we specify that PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 the proposed AD would add an allowable time for the optional terminating action (provided by the existing AD). However, in paragraph (h) of the proposed AD we did not include that ‘‘allowable time’’ for accomplishing the optional terminating action. This decision was based on the fact that the French airworthiness directive referenced in the proposed AD did not specify an allowable time for the optional terminating action, so it was not necessary to state that time in the proposed AD. In light of the above, we have removed the wording ‘‘* * * would add an allowable time for the optional terminating action * * *’’ from the new actions in the Summary section. The Relevant Service Information and FAA’s Determination and Requirements of the proposed AD sections are not restated in the final rule. In addition, certain other wording in the preamble specifies that the new AD reduces the compliance threshold, but it also extends the compliance threshold for certain airplanes. Therefore, we have changed the wording to specify that the new AD revises the compliance threshold. Clarification of Paragraph (f)(2) of Proposed AD For clarification, we are explaining an inadvertent error in paragraph (f)(2) of the proposed AD. Paragraph (f)(2) of the proposed AD specified doing the inspection at the later of the times specified in paragraph (f)(1)(i) and (f)(1)(ii) of the AD; the correct citation is paragraphs (f)(2)(i) and (f)(2)(ii) of the AD. Conclusion We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance This AD will affect about 269 airplanes of U.S. registry. The ultrasonic inspection that is required by AD 99–01–17 and retained in this AD takes about 6 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the currently required ultrasonic inspection is $390 per airplane, per inspection cycle.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with an AD for certain Gulfstream Aerospace LP Model Gulfstream 100 
airplanes; and Model Astra SPX and 1125 Westwind Astra series 
airplanes. That action, published in the Federal Register on October 4, 
2004 (69 FR 59147), proposed to require adjusting the ground contact 
switches of the main landing gear.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been submitted on the proposed 
AD 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 as proposed.

Costs of Compliance

    This AD will affect about 106 airplanes of U.S. registry. The 
actions will take about 3 work hours per airplane, at an average labor 
rate of $65 per work hour. Based on these figures, the estimated cost 
of the AD for U.S. operators is $20,670, or $195 per airplane.

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. See the ADDRESSES section for a location to 
examine the regulatory evaluation.
