DEPARTMENT OF AGRICULTURE Agricultural Marketing Service 7 CFR Part 956 [Docket No. AMS–FV–13–0024; FV13–956– 1 CR] Sweet Onions Grown in the Walla Walla Valley of Southeast Washington and Northeast Oregon; Continuance Referendum Agricultural Marketing Service, USDA. ACTION: Referendum order. AGENCY: This document directs that a referendum be conducted among eligible producers of sweet onions in the Walla Walla Valley of southeast Washington and northeast Oregon, to determine whether they favor continuance of the marketing order regulating the handling of sweet onions produced in the production area. DATES: The referendum will be conducted from September 14 through October 4, 2013. To vote in this referendum, producers must have produced Walla Walla sweet onions within the designated production area in Washington and Oregon during the period January 1 through December 31, 2012. ADDRESSES: Copies of the marketing order may be obtained from the referendum agents at 805 SW. Broadway, Suite 930, Portland, OR 97205, or the Office of the Docket Clerk, Marketing Order and Agreement Division, Fruit and Vegetable Program, AMS, USDA, 1400 Independence Avenue SW., STOP 0237, Washington, DC 20250–0237; Fax: (202) 720–8938; or Internet: www.regulations.gov.

SUPPLEMENTARY INFORMATION: Pursuant to Marketing Agreement and Order No. 956, both as amended (7 CFR Part 956), hereinafter referred to as the ‘‘order,’’ and the applicable provisions of the Agricultural Marketing Agreement Act of 1937, as amended (7 U.S.C. 601–674), hereinafter referred to as the ‘‘Act,’’ it is hereby directed that a referendum be conducted to ascertain whether continuance of the order is favored by the producers. The referendum shall be conducted from September 14 through October 4, 2013, among Walla Walla sweet onion producers in the production area. Only Walla Walla sweet onion producers that were engaged in the production of Walla Walla sweet onions in Washington and Oregon, during the period of January 1 through December 31, 2012, may participate in the continuance referendum. USDA has determined that continuance referenda are an effective means for determining whether producers favor the continuation of marketing order programs. USDA would consider termination of the order if a majority of the producers voting in the referendum and producers of a majority of the volume of Walla Walla sweet onions represented in the referendum do not favor continuance. In evaluating the merits of continuance versus termination, USDA will not exclusively consider the results of the continuance referendum. USDA will also consider all other relevant information concerning the operation of the order and the relative benefits and disadvantages to producers, handlers, and consumers in order to determine whether continued operation of the order would tend to effectuate the declared policy of the Act. In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501– 3520), the ballot materials to be used in the referendum herein ordered have been submitted to and approved by the Office of Management and Budget (OMB) and have been assigned OMB No. 0581–0178, Vegetable and Specialty Crop Marketing Orders. It has been estimated that it will take an average of 20 minutes for each of the approximately 21 producers of Walla Walla sweet onions in Washington and Oregon to cast a ballot. Participation is PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 voluntary. Ballots postmarked after October 4, 2013, will not be included in the vote tabulation. Manuel Michel and Gary D. Olson of the Northwest Marketing Field Office, Fruit and Vegetable Program, AMS, USDA, are hereby designated as the referendum agents of the Secretary of Agriculture to conduct this referendum. The procedure applicable to the referendum shall be the ‘‘Procedure for the Conduct of Referenda in Connection With Marketing Orders for Fruits, Vegetables, and Nuts Pursuant to the Agricultural Marketing Agreement Act of 1937, as Amended’’ (7 CFR 900.400– 900.407). Ballots will be mailed to all producers of record and may also be obtained from the referendum agents, or from their appointees.

SUPPLEMENTARY INFORMATION: VerDate Mar<15>2010 16:29 Jun 19, 2013 Jkt 229001 Comments Invited We invite you to participate in this rulemaking by submitting written comments, data, or views. We also invite comments relating to the economic, environmental, energy, or federalism impacts that might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time. We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. The European Aviation Safety Agency (EASA), which is the aviation authority for Germany, has issued EASA AD No. 2010–0128, dated June 25, 2010 (EASA 2010–0128), to correct an unsafe condition for Model BO 105 C, BO 105 D, and BO 105 S helicopters, and certain variants of those models. EASA advises that several failures of third stage turbine wheels used in Rolls Royce Corporation (RRC) 250 series engines have occurred. According to EASA, RRC has determined that detrimental vibrations can occur within a particular range of turbine speeds, and may be a contributing factor to these failures. This condition, if not corrected, could result in loss of engine power, possibly resulting in an emergency landing and injuries to the helicopter occupants. To address this, RRC issued Commercial Engine Bulletin (CEB) A–1400, now at revision 3, for engines with a third stage turbine wheel, part number (P/N) 23065833, installed. CEB A–1400 introduces an operational limitation to avoid engine power turbine (N2) steadystate operation in a speed range between 86.5% and 95.5% for more than 60 seconds in single or cumulative events. In response, ECD has revised the RFM and has provided a placard to inform pilots to avoid steady-state operations Frm 00002 between 86.5% and 95.5% turbine speeds. The EASA AD requires amending the RFMs and installing a placard as described in ECD Alert Service Bulletin No. BO105–60–110, Revision 1, dated March 3, 2010 (ASB BO105). FAA’s Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other helicopters of the same type design. Related Service Information ECD has issued ASB BO105, which contains procedures for installing a placard on the instrument panel stating the prohibited steady-state turbine operating range. Revision 1 of ASB BO105 removed the temporary RFM pages as these changes were included in the most recent revisions of the BO105C/CS and BO105CB/CBS RFMs. Proposed AD Requirements Discussion PO 00000 37151 Fmt 4702 Sfmt 4702 This proposed AD would require installing a placard on the instrument panel next to the triple RPM indicator and revising the Operating Limitations sections of the Model BO 105C/CS and BO105 CB/CBS RFMs to limit steadystate operations between speeds of 86.5% and 95.5%. Costs of Compliance We estimate that this proposed AD would affect 80 helicopters of U.S. Registry. Based on an average labor rate of $85 per hour, we estimate that operators may incur the following costs in order to comply with this AD. Amending the RFM would require about 0.5 workhours, for a cost per helicopter of about $43 and a cost to U.S. operators of $3,440. Installing the decal would require about 0.2 work-hours, and required parts would cost about $5, for a cost per helicopter of $22 and a cost to U.S. operators of $1,760. Based on these estimates, the total cost of this proposed AD would be $65 per helicopter and $5,200 for the U.S. operator fleet. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, E:\FR\FM\20JNP1.SGM 20JNP1 37152 Federal Register / Vol. 78, No. 119 / Thursday, June 20, 2013 / Proposed Rules 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, 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); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and 4. 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 an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Discussion

    The European Aviation Safety Agency (EASA), which is the aviation 
authority for Germany, has issued EASA AD No. 2010-0128, dated June 25, 
2010 (EASA 2010-0128), to correct an unsafe condition for Model BO 105 
C, BO 105 D, and BO 105 S helicopters, and certain variants of those 
models. EASA advises that several failures of third stage turbine 
wheels used in Rolls Royce Corporation (RRC) 250 series engines have 
occurred. According to EASA, RRC has determined that detrimental 
vibrations can occur within a particular range of turbine speeds, and 
may be a contributing factor to these failures. This condition, if not 
corrected, could result in loss of engine power, possibly resulting in 
an emergency landing and injuries to the helicopter occupants. To 
address this, RRC issued Commercial Engine Bulletin (CEB) A-1400, now 
at revision 3, for engines with a third stage turbine wheel, part 
number (P/N) 23065833, installed. CEB A-1400 introduces an operational 
limitation to avoid engine power turbine (N2) steady-state operation in 
a speed range between 86.5% and 95.5% for more than 60 seconds in 
single or cumulative events. In response, ECD has revised the RFM and 
has provided a placard to inform pilots to avoid steady-state 
operations between 86.5% and 95.5% turbine speeds.
    The EASA AD requires amending the RFMs and installing a placard as 
described in ECD Alert Service Bulletin No. BO105-60-110, Revision 1, 
dated March 3, 2010 (ASB BO105).

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Germany and are approved for operation in the United States. Pursuant 
to our bilateral agreement with Germany, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other helicopters of the same type design.

Related Service Information

    ECD has issued ASB BO105, which contains procedures for installing 
a placard on the instrument panel stating the prohibited steady-state 
turbine operating range. Revision 1 of ASB BO105 removed the temporary 
RFM pages as these changes were included in the most recent revisions 
of the BO105C/CS and BO105CB/CBS RFMs.

Proposed AD Requirements

    This proposed AD would require installing a placard on the 
instrument panel next to the triple RPM indicator and revising the 
Operating Limitations sections of the Model BO 105C/CS and BO105 CB/CBS 
RFMs to limit steady-state operations between speeds of 86.5% and 
95.5%.

Costs of Compliance

    We estimate that this proposed AD would affect 80 helicopters of 
U.S. Registry.
    Based on an average labor rate of $85 per hour, we estimate that 
operators may incur the following costs in order to comply with this 
AD. Amending the RFM would require about 0.5 work-hours, for a cost per 
helicopter of about $43 and a cost to U.S. operators of $3,440. 
Installing the decal would require about 0.2 work-hours, and required 
parts would cost about $5, for a cost per helicopter of $22 and a cost 
to U.S. operators of $1,760. Based on these estimates, the total cost 
of this proposed AD would be $65 per helicopter and $5,200 for the U.S. 
operator fleet.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I,

[[Page 37152]]

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, 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);
    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; and
    4. 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 an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.
