Prior to arriving at this budget, the Board considered alternative expenditure levels, but ultimately decided that the recommended levels were reasonable to properly administer the order. Unexpended funds may be used temporarily to defray expenses of the subsequent marketing year, but must be made available to the handlers from whom collected within 5 months after the end of the year, according to § 984.69. According to NASS, the season average grower prices for years 2004 and 2005 were $1,390 and $1,520 per ton, respectively. Dividing these average grower prices by 2,000 pounds per ton provides an inshell price per pound range of between $.70 and $.76. Adjusting by a few cents above and below those prices ($0.67 to $0.79 per inshell pound) provides a reasonable price range within which the 2006–07 season average price is likely to fall. Dividing these inshell prices per pound by the 0.45 conversion factor designated in the order yields a 2006–07 price range estimate of $1.49 and $1.76 per kernelweight pound of assessable walnuts. To calculate the percentage of grower revenue represented by the assessment rate, the assessment rate of $0.0101 (per kernelweight pound) is divided by the low and high estimates of the price range and then multiplied by 100. The estimated assessment revenue for the 2006–07 marketing year as a percentage of total grower revenue would likely range between .7 and .6 percent. This action continues in effect the action that increased the assessment obligation imposed on handlers. While assessments impose some additional costs on handlers, the costs are minimal and uniform on all handlers. Some of the additional costs may be passed on to producers. However, these costs are offset by the benefits derived by the operation of the marketing order. In addition, the Board’s meeting was widely publicized throughout the California walnut industry and all interested persons were invited to VerDate Aug<31>2005 21:54 Mar 05, 2007 Jkt 211001 attend the meeting and participate in Board deliberations on all issues. Like all Board meetings, the September 8, 2006, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. This action imposes no additional reporting or recordkeeping requirements on either small or large California walnut handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. The AMS is committed to complying with the E-Government Act, to promote the use of the Internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes. USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. An interim final rule concerning this action was published in the Federal Register on November 16, 2006 (71 FR 66645). Copies of the rule were also mailed by the Board’s staff to all Board members and walnut handlers. In addition, the interim final rule was made available through the Internet by USDA and the Office of the Federal Register. The rule provided for a 60-day comment period, which ended on January 16, 2007, and no comments were received.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires inspecting the carbon-fiber reinforced plastic main landing gear (MLG) door to determine whether certain part numbers are installed. For airplanes having certain doors, this AD requires inspecting the MLG outboard door for cracks, play, and loose sealant/bolts/nuts, and related E:\FR\FM\06MRR1.SGM 06MRR1 9844 Federal Register / Vol. 72, No. 43 / Tuesday, March 6, 2007 / Rules and Regulations investigative and corrective actions if necessary. This AD also requires, for airplanes having certain doors, modifying the rod bracket attachment of the MLG outboard door. This AD results from a report of a rod bracket of the MLG door detaching during flight. We are issuing this AD to detect and correct cracks in the rod bracket attachment bolts, which could result in the rod brackets detaching from the MLG door and blocking the proper functioning of the MLG. DATES: This AD becomes effective April 10, 2007. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of April 10, 2007.

Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all Fokker Model F.28 Mark 0070 and 0100 airplanes. That NPRM was published in the Federal Register on December 28, 2006 (71 FR 78099). That NPRM proposed to require inspecting the carbon-fiber reinforced plastic main landing gear (MLG) door to determine whether certain part numbers are installed. For airplanes having certain doors, that NPRM proposed to require inspecting the MLG outboard door for cracks, play, and loose sealant/ bolts/nuts, and related investigative and corrective actions if necessary. That NPRM also proposed to require, for airplanes having certain doors, modifying the rod bracket attachment of the MLG outboard door. 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 as proposed. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this AD. ESTIMATED COSTS Action Inspections ............................................... Modification .............................................. 2 6 rwilkins on PROD1PC63 with RULES 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.

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.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to all Fokker Model F.28 
Mark 0070 and 0100 airplanes. That NPRM was published in the Federal 
Register on December 28, 2006 (71 FR 78099). That NPRM proposed to 
require inspecting the carbon-fiber reinforced plastic main landing 
gear (MLG) door to determine whether certain part numbers are 
installed. For airplanes having certain doors, that NPRM proposed to 
require inspecting the MLG outboard door for cracks, play, and loose 
sealant/bolts/nuts, and related investigative and corrective actions if 
necessary. That NPRM also proposed to require, for airplanes having 
certain doors, modifying the rod bracket attachment of the MLG outboard 
door.

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 as proposed.

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.
