ACTION: Proposed rule; correction. rmajette on PROD1PC64 with PROPOSALS AGENCY: SUMMARY: We are correcting an error in our proposed rule to amend the regulations to allow the importation into the continental United States of fresh blueberries from South Africa and Uruguay under certain conditions and to allow the use of cold treatment for blueberries imported into the United States from Argentina. The proposed rule was published in the Federal Register on June 5, 2007 (72 FR 30979– 30984, Docket No. APHIS 2007–0061). FOR FURTHER INFORMATION CONTACT: Mr. ´ Tony Roman, Import Specialist, Commodity Import Analysis and Operation Staff, PPQ, APHIS, 4700 River Road Unit 133, Riverdale, MD 20737–1231; (301) 734–8758. SUPPLEMENTARY INFORMATION: On June 5, 2007, we published in the Federal Register (72 FR 30979–30984, Docket No. APHIS–2007–0061) a proposed rule to allow the importation into the continental United States of fresh blueberries from South Africa and Uruguay under certain conditions. As a condition of entry, the blueberries would have to undergo cold treatment and would have to be accompanied by a phytosanitary certificate issued by the national plant protection organization (NPPO) of the exporting country. In addition, we also proposed to allow the use of cold treatment for blueberries imported into the United States from Argentina. VerDate Aug<31>2005 15:14 Jun 14, 2007 Jkt 211001 In two places in the Supplementary Information section of the proposed rule and in one place in the regulatory text, we stated that we would require shipments of blueberries from South Africa and Uruguay to be accompanied by a phytosanitary certificate issued by the NPPO of the importing country. This information was incorrect. We should have stated that we would require shipments of blueberries from South Africa and Uruguay to be accompanied by a phytosanitary certificate issued by the NPPO of the exporting country. This document corrects those errors. Correction In FR Doc. E7–10818, published on June 5, 2007 (72 FR 30979–30984) make the following corrections: On page 30980, first column, fourteenth line following the second table; on page 30981, first column, tenth line; and on page 30984, first column, in proposed § 319.56–2vv(b), correct ‘‘importing’’ to read ‘‘exporting’’.

ADDRESSES Discussion The Civil Aviation Authority (CAA), which is the aviation authority for New Zealand, has issued AD DCA/750XL/9, dated March 29, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: To prevent damage to the rear spar due to working and failing rivets between the rear spar and the inboard rib * * * The MCAI requires inspecting the inboard end of the rear spar for security of the blind rivets, inspecting the radii of the rear spar upper and lower flanges for cracking, inspecting the aft flange of the inboard rib for cracking, replacing the rear spar if cracks are found in any of the inspections, and modifying the rear spar by replacing the blind rivets with bolts or rivets. You may obtain further information by examining the MCAI in the AD docket. rmajette on PROD1PC64 with PROPOSALS Relevant Service Information Pacific Aerospace Limited has issued Mandatory Service Bulletin PACSB/XL/ 022, dated February 14, 2007. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. VerDate Aug<31>2005 15:14 Jun 14, 2007 Jkt 211001 Differences Between This Proposed 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 proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 7 products of U.S. registry. We also estimate that it would take about 40 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $200 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 costs. 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 the proposed AD on U.S. operators to be $23,800, or $3,400 per product. In addition, we estimate that any necessary follow-on actions would take about 40 work-hours and require parts costing $750, for a cost of $3,950 per product. This cost estimate is per side. We have no way of determining the number of products that may need these actions. 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 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 33167 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: 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 proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Discussion

    The Civil Aviation Authority (CAA), which is the aviation authority 
for New Zealand, has issued AD DCA/750XL/9, dated March 29, 2007 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    To prevent damage to the rear spar due to working and failing 
rivets between the rear spar and the inboard rib * * *

    The MCAI requires inspecting the inboard end of the rear spar for 
security of the blind rivets, inspecting the radii of the rear spar 
upper and lower flanges for cracking, inspecting the aft flange of the 
inboard rib for cracking, replacing the rear spar if cracks are found 
in any of the inspections, and modifying the rear spar by replacing the 
blind rivets with bolts or rivets.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Pacific Aerospace Limited has issued Mandatory Service Bulletin 
PACSB/XL/022, dated February 14, 2007. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed 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 proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 7 products of U.S. registry. We also estimate that 
it would take about 40 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $200 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 costs. 
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 the proposed AD on 
U.S. operators to be $23,800, or $3,400 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 40 work-hours and require parts costing $750, for a cost of 
$3,950 per product. This cost estimate is per side. We have no way of 
determining the number of products that may need these actions.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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 proposed AD and placed it in the AD docket.
