Thus, where the second tier CUSO is itself wholly owned by a wholly owned first tier CUSO, use of a consolidated opinion audit capturing both levels would be permissible. Regulatory Procedures Regulatory Flexibility Act The final rule relieves a CUSO that is wholly owned from having to secure a separate opinion audit of its books, if it is included in the annual consolidated opinion audit of the credit union that is its parent. The Board has determined and certifies that the rule will not have a significant economic impact on a substantial number of small credit unions. Accordingly, the NCUA Board has determined that a Regulatory Flexibility Analysis is not required. Paperwork Reduction Act NCUA has determined that the proposed regulation does not increase paperwork requirements under the Paperwork Reduction Act of 1995 and regulations of the Office of Management and Budget. Executive Order 13132 Executive Order 13132 encourages independent regulatory agencies to consider the impact of their actions on state and local interests. In adherence to fundamental federalism principles, NCUA, an independent regulatory agency as defined in 44 U.S.C. 3502(5), voluntarily complies with the executive order. The final rule will apply only to federally-chartered credit unions. It will not have substantial direct effects 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. NCUA has determined that this proposal does not constitute a policy that has federalism implications for purposes of the executive order.

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 Airbus Model A318, A319, A320, and A321 series airplanes. That NPRM was published in the Federal Register on May 12, 2005 (70 FR 24997). That NPRM proposed to require modification of the electrical bonding of all structures and systems installed inside the center fuel tank. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Support for the Proposed AD One commenter supports the proposed AD. Request To Extend Compliance Time Request To Consider Effect of Other Rulemaking One commenter requests that we revise the ‘‘Discussion’’ and ‘‘FAA’s Determination and Requirements of the Proposed AD’’ sections of the proposed AD to describe the relationship of the proposed AD to the NPRM on Reducing Fuel Tank Flammability (referred to after this as the ‘‘FTF rule’’), which was announced by the FAA Administrator in February 2004. The commenter notes that airplanes affected by the proposed AD are included in the applicability of the FTF NPRM. Further, the commenter expects that the unsafe condition addressed by the proposed AD would be mitigated by doing the requirements of the FTF rule, so the FTF rule would preclude the need for the proposed AD. The commenter concludes that the FAA did not consider all pertinent data when it issued the proposed AD and, consequently, the FAA’s determination and requirements of the proposed AD may be flawed. While the commenter asks for specific changes only to the preamble of the proposed AD, we infer that the commenter is requesting that we withdraw the proposed AD. We do not concur. Reducing flammability and minimizing potential ignition sources comprise the FAA’s two-pronged, balanced approach to fuel tank safety. Since the introduction of turbinepowered airplanes, the FAA’s primary means of protection from fuel tank explosions has been to eliminate ignition sources. The fuel tank rules are VerDate Aug<31>2005 14:27 Sep 20, 2005 Jkt 205001 based on the assumption that fuel tanks will always contain flammable vapors. However, one of the important lessons learned as a result of the fuel tank safety reviews required by Special Federal Aviation Regulation No. 88 (‘‘SFAR 88,’’ amendment 21–78, and subsequent amendments 21–82 and 21–83) is that unanticipated failures and maintenance errors will continue to generate unexpected ignition sources. Thus, we have concluded that we are unlikely ever to identify and eradicate all possible sources of ignition. Our balanced approach means that, while we pursue reducing flammability through efforts such as the Fuel Tank Flammability (FTF) rule, we will also continue to eliminate identified ignition sources, such as those identified as a result of the SFAR 88 fuel tank safety reviews. This AD is consistent with that effort. We have not changed the AD in this regard. One commenter requests that we extend the compliance time from 58 months to 72 months after the effective date of the AD. The commenter states that many operators have increased their heavy maintenance interval from 5 years to 6 years. Thus, the commenter states that increasing the compliance time to 72 months would allow for minimum disruption to its operating schedule. We do not concur. We have determined that the 58-month compliance time, as proposed, represents the maximum interval of time allowable for the affected airplanes to continue to operate safely before the modification is done. In developing an appropriate compliance time for this AD, we considered, among other factors, the manufacturer’s recommendation and the degree of urgency associated with the subject unsafe condition. We have not changed this AD in this regard. Request To Increase Estimated Costs of Compliance Two commenters request that we revise the estimated costs of compliance stated in the proposed AD. One commenter states that the service bulletin to which the proposed AD refers estimates that the modification will take 132 to 141 work hours, but the commenter’s own experience indicates that the modification will take 200 to 215 work hours. The other commenter states that the service bulletin estimates the total work hours as 129 to 146.5, but it estimates up to 443 work hours (including time required for fuel tank guard personnel) will be needed. PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 55229 We do not concur. The estimates of 129 to 146.5 work hours specified in the service bulletin include time for gaining access and closing up. The cost analysis in AD rulemaking actions, however, typically does not include costs such as the time required to gain access and close up, time necessary for planning, or time necessitated by other administrative actions. Those incidental costs may vary significantly among operators and are almost impossible to calculate. We recognize that, in doing the actions required by an AD, operators may incur incidental costs in addition to the direct costs. However, the estimate of 49 to 64 work hours, as proposed and as specified in this AD, represents the time necessary to perform only the actions actually required by this AD. We have not changed the AD in this regard. Explanation of Change to Applicability The FAA has revised the applicability of this AD to identify model designations as published in the most recent type certificate data sheet for the affected models. Conclusion We have carefully reviewed the available data, including the comments received, 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 affects about 506 airplanes of U.S. registry. The required actions take between 49 and 64 work hours per airplane depending on the airplane’s configuration. The average labor rate is $65 per work hour. Required parts cost between $10 and $370 per airplane, depending on the airplane’s configuration. Based on these figures, the estimated cost of this AD for U.S. operators is between $1,616,670 and $2,292,180, or between $3,195 and $4,530 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 E:\FR\FM\21SER1.SGM 21SER1 55230 Federal Register / Vol. 70, No. 182 / Wednesday, September 21, 2005 / Rules and Regulations 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.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. That AD currently requires operators to determine the number of flight cycles accumulated on each component of the main landing gear (MLG) and the nose landing gear (NLG), and to replace each component that reaches its life limit with a serviceable component. The existing AD also requires operators to revise the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness in the aircraft maintenance manual to reflect the new life limits. This new AD requires revising the ALS to incorporate extended and more restrictive life limits for structurally significant items. This AD is prompted by engineering analysis of fleet operations which resulted in more restrictive life limits. We are issuing this AD to prevent failure of certain structurally significant items, including the MLG and the NLG, which could result in reduced structural integrity of the airplane.

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 Airbus Model 
A318, A319, A320, and A321 series airplanes. That NPRM was published in 
the Federal Register on May 12, 2005 (70 FR 24997). That NPRM proposed 
to require modification of the electrical bonding of all structures and 
systems installed inside the center fuel tank.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Support for the Proposed AD

    One commenter supports the proposed AD.

Request To Consider Effect of Other Rulemaking

    One commenter requests that we revise the ``Discussion'' and 
``FAA's Determination and Requirements of the Proposed AD'' sections of 
the proposed AD to describe the relationship of the proposed AD to the 
NPRM on Reducing Fuel Tank Flammability (referred to after this as the 
``FTF rule''), which was announced by the FAA Administrator in February 
2004. The commenter notes that airplanes affected by the proposed AD 
are included in the applicability of the FTF NPRM. Further, the 
commenter expects that the unsafe condition addressed by the proposed 
AD would be mitigated by doing the requirements of the FTF rule, so the 
FTF rule would preclude the need for the proposed AD. The commenter 
concludes that the FAA did not consider all pertinent data when it 
issued the proposed AD and, consequently, the FAA's determination and 
requirements of the proposed AD may be flawed.
    While the commenter asks for specific changes only to the preamble 
of the proposed AD, we infer that the commenter is requesting that we 
withdraw the proposed AD. We do not concur. Reducing flammability and 
minimizing potential ignition sources comprise the FAA's two-pronged, 
balanced approach to fuel tank safety. Since the introduction of 
turbine-powered airplanes, the FAA's primary means of protection from 
fuel tank explosions has been to eliminate ignition sources. The fuel 
tank rules are based on the assumption that fuel tanks will always 
contain flammable vapors. However, one of the important lessons learned 
as a result of the fuel tank safety reviews required by Special Federal 
Aviation Regulation No. 88 (``SFAR 88,'' amendment 21-78, and 
subsequent amendments 21-82 and 21-83) is that unanticipated failures 
and maintenance errors will continue to generate unexpected ignition 
sources. Thus, we have concluded that we are unlikely ever to identify 
and eradicate all possible sources of ignition.
    Our balanced approach means that, while we pursue reducing 
flammability through efforts such as the Fuel Tank Flammability (FTF) 
rule, we will also continue to eliminate identified ignition sources, 
such as those identified as a result of the SFAR 88 fuel tank safety 
reviews. This AD is consistent with that effort. We have not changed 
the AD in this regard.

Request To Extend Compliance Time

    One commenter requests that we extend the compliance time from 58 
months to 72 months after the effective date of the AD. The commenter 
states that many operators have increased their heavy maintenance 
interval from 5 years to 6 years. Thus, the commenter states that 
increasing the compliance time to 72 months would allow for minimum 
disruption to its operating schedule.
    We do not concur. We have determined that the 58-month compliance 
time, as proposed, represents the maximum interval of time allowable 
for the affected airplanes to continue to operate safely before the 
modification is done. In developing an appropriate compliance time for 
this AD, we considered, among other factors, the manufacturer's 
recommendation and the degree of urgency associated with the subject 
unsafe condition. We have not changed this AD in this regard.

Request To Increase Estimated Costs of Compliance

    Two commenters request that we revise the estimated costs of 
compliance stated in the proposed AD. One commenter states that the 
service bulletin to which the proposed AD refers estimates that the 
modification will take 132 to 141 work hours, but the commenter's own 
experience indicates that the modification will take 200 to 215 work 
hours. The other commenter states that the service bulletin estimates 
the total work hours as 129 to 146.5, but it estimates up to 443 work 
hours (including time required for fuel tank guard personnel) will be 
needed.
    We do not concur. The estimates of 129 to 146.5 work hours 
specified in the service bulletin include time for gaining access and 
closing up. The cost analysis in AD rulemaking actions, however, 
typically does not include costs such as the time required to gain 
access and close up, time necessary for planning, or time necessitated 
by other administrative actions. Those incidental costs may vary 
significantly among operators and are almost impossible to calculate. 
We recognize that, in doing the actions required by an AD, operators 
may incur incidental costs in addition to the direct costs. However, 
the estimate of 49 to 64 work hours, as proposed and as specified in 
this AD, represents the time necessary to perform only the actions 
actually required by this AD. We have not changed the AD in this 
regard.

Explanation of Change to Applicability

    The FAA has revised the applicability of this AD to identify model 
designations as published in the most recent type certificate data 
sheet for the affected models.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, 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 affects about 506 airplanes of U.S. registry. The required 
actions take between 49 and 64 work hours per airplane depending on the 
airplane's configuration. The average labor rate is $65 per work hour. 
Required parts cost between $10 and $370 per airplane, depending on the 
airplane's configuration. Based on these figures, the estimated cost of 
this AD for U.S. operators is between $1,616,670 and $2,292,180, or 
between $3,195 and $4,530 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

[[Page 55230]]

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
