Download as PDF jstallworth on DSK7TPTVN1PROD with PROPOSALS Federal Register / Vol. 80, No. 214 / Thursday, November 5, 2015 / Proposed Rules handlers. While assessments impose some additional costs on handlers, the costs are minimal and uniform on all handlers. However, these costs would be offset by the benefits derived by the operation of the marketing order. In addition, the Committee’s meetings were widely publicized throughout the California kiwifruit industry and all interested persons were invited to attend the meeting and participate in Committee deliberations on all issues. Like all Committee meetings, the July 17 and September 16, 2015, meetings, were public meetings and all entities, both large and small, were able to express views on this issue. Finally, interested persons are invited to submit comments on this proposed rule, including the regulatory and informational impacts of this action on small businesses. In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C Chapter 35), the order’s information collection requirements have been previously approved by the Office of Management and Budget (OMB) and assigned OMB No. 0581–0189. No changes in those requirements are necessary as a result of this action. Should any changes become necessary, they would be submitted to OMB for approval. This proposed rule would impose no additional reporting or recordkeeping requirements on either small or large California kiwifruit 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. 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 action. A small business guide on complying with fruit, vegetable, and specialty crop marketing agreements and orders may be viewed at: https://www.ams.usda.gov/ MarketingOrdersSmallBusinessGuide. Any questions about the compliance guide should be sent to Jeffrey Smutny at the previously mentioned address in the FOR FURTHER INFORMATION CONTACT section. A 15-day comment period is provided to allow interested persons to respond to this proposed rule. Fifteen days is deemed appropriate because: (1) The 2015–16 fiscal year began on August 1, 2015, handlers began shipping kiwifruit in September and the marketing order VerDate Sep<11>2014 14:36 Nov 04, 2015 Jkt 238001 requires that the rate of assessment apply to all assessable kiwifruit handled during the fiscal period; (2) the Committee needs to have sufficient funds to pay its expenses, which are incurred on a continuous basis; and (3) handlers are aware of this action which was unanimously recommended by the Committee at a public meeting and is similar to other assessment rate actions issued in past years. List of Subjects in 7 CFR Part 920 Kiwifruit, Marketing agreements, Reporting and record keeping requirements. For the reasons set forth in the preamble, 7 CFR part 920 is proposed to be amended as follows: PART 920—KIWIFRUIT GROWN IN CALIFORNIA 1. The authority citation for 7 CFR part 920 continues to read as follows: ■ Authority: 7 U.S.C. 601–674. 2. Section 920.213 is revised to read as follows: ■ § 920.213 Assessment rate. On and after August 1, 2015, an assessment rate of $0.040 per 9-kilo volume-fill container or equivalent of kiwifruit is established for kiwifruit grown in California. Dated: October 30, 2015. Rex A.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2015– 0177, dated August 25, 2015 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Several cases of torque conformation box (TCB) failures have been reported on engines incorporating mod TU34 or mod TU34A. Investigation concluded that these failures were caused by cracks on soldered joints of TCB resistors. This condition, if not corrected, could lead to limited power availability in a One Engine Inoperative (OEI) case, possibly resulting in reduced control of the helicopter. You may obtain further information by examining the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 3805. jstallworth on DSK7TPTVN1PROD with PROPOSALS Related Service Information Under 1 CFR Part 51 Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 292 72 2860, Version A, dated July 15, 2015. The MSB describes procedures for checking TCB resistance values. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of France, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all VerDate Sep<11>2014 14:36 Nov 04, 2015 Jkt 238001 information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require inspecting the TCB for correct resistance values and removing TCBs that fail inspection. Costs of Compliance We estimate that this proposed AD affects 300 engines installed on helicopters of U.S. registry. We estimate that it would take about 1 hour to perform an inspection. We also estimate that 20% of these engines would fail the inspection and require TCB removal, which would take about 1 hour. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $30,600. 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), (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 (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.

Discussion We received a report that, during a preflight inspection, an operator noted limited travel of the control yoke on a Quest Aircraft Design, LLC Model KODIAK 100 airplane. Upon further inspection of the control yoke system forward of the control yoke, cushion edging was found jammed in the elevator control anti-rotation guide slot. The jammed edging prevented the control yoke from having full nose up and nose down travel. The operator also reported the same problem on a different KODIAK 100 airplane in which the cushion edging plastic portion separated from the metal track. Investigation revealed that over time the cushion edging may become worn and degrade. This condition, if not corrected, could result in failure of the elevator control system cushion edging, which could restrict elevator control yoke movement and cause loss of control. Relevant Service Information We reviewed Quest Aircraft KODIAK Mandatory Service Bulletin SB14–07, dated August 26, 2014; Quest Aircraft Field Service Instruction, Elevator Control System—Cushion Edging Inspection, Report No. FSI–105, Revision 00, not dated; Quest Aircraft KODIAK 100 Recommended Service Bulletin SB15–01, dated March 26, 2015; and Quest Aircraft Field Service Instruction, Yoke Anti-Rotation Guide Wear Pad Upgrade, Report No. FSI–108, Revision 00, not dated.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2015-0177, dated August 25, 2015 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Several cases of torque conformation box (TCB) failures have 
been reported on engines incorporating mod TU34 or mod TU34A. 
Investigation concluded that these failures were caused by cracks on 
soldered joints of TCB resistors.
    This condition, if not corrected, could lead to limited power 
availability in a One Engine Inoperative (OEI) case, possibly 
resulting in reduced control of the helicopter.

    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2015-3805.

Related Service Information Under 1 CFR Part 51

    Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 292 
72 2860, Version A, dated July 15, 2015. The MSB describes procedures 
for checking TCB resistance values. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with the European Community, EASA has 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 provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design. This proposed AD would require inspecting the TCB for correct 
resistance values and removing TCBs that fail inspection.

Costs of Compliance

    We estimate that this proposed AD affects 300 engines installed on 
helicopters of U.S. registry. We estimate that it would take about 1 
hour to perform an inspection. We also estimate that 20% of these 
engines would fail the inspection and require TCB removal, which would 
take about 1 hour. The average labor rate is $85 per hour. Based on 
these figures, we estimate the cost of this proposed AD on U.S. 
operators to be $30,600.

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),
    (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.
