The Committee’s crop year begins on October 1, and ends on September 30. In an interim rule published in the Federal Register on October 28, 2015, and effective on October 29, 2015 (80 FR 65886, Doc. No. AMS–FV–15–0034, FV15–987–1 IR), § 987.339 was amended by decreasing the assessment rate established for California dates for the 2015–16 and subsequent crop years from $0.20 to $0.10 per hundredweight of dates. The decrease in the per hundredweight assessment rate allows the Committee to reduce its financial reserve while still providing adequate funding to meet program expenses. Final Regulatory Flexibility Analysis Pursuant to requirements set forth in the Regulatory Flexibility Act (RFA) (5 U.S.C. 601–612), the Agricultural Marketing Service (AMS) has considered the economic impact of this rule on small entities. Accordingly, AMS has prepared this final regulatory flexibility analysis. The purpose of the RFA is to fit regulatory actions to the scale of businesses subject to such actions in order that small businesses will not be unduly or disproportionately burdened. Marketing orders issued pursuant to the Act, and the rules issued thereunder, are unique in that they are brought about through group action of essentially small entities acting on their own behalf. There are approximately 70 producers of dates in the production area and 11 handlers subject to regulation under the marketing order. The Small Business Administration defines small agricultural producers as those having annual receipts of less than $750,000, and small agricultural service firms as those whose annual receipts are less than $7,500,000. (13 CFR 121.201) According to the National Agricultural Statistics Service (NASS), data for the most-recently completed crop year (2014) shows that about 3.54 tons, or 7,080 pounds, of dates were produced per acre. The 2014 producer price published by NASS was $1,190 per ton. Thus, the value of date production per acre in 2014–15 averaged about $4,213 (3.54 tons times $1,190 per ton). At that average price, a producer would have to farm over 178 acres to receive an annual income from dates of $750,000 ($750,000 divided by $4,213 per acre equals 178.02 acres). According to committee staff, the majority of California date producers farm less than 178 acres. Thus, it can be concluded that the majority of date producers could be considered small VerDate Sep<11>2014 17:33 Feb 25, 2016 Jkt 238001 entities. In addition, according to data from the committee staff, the majority of handlers of California dates have receipts of less than $7,500,000 and may also be considered small entities. This rule continues in effect the action that decreased the assessment rate established for the committee and collected from handlers for the 2015–16 and subsequent crop years from $0.20 to $0.10 per hundredweight of dates. The committee unanimously recommended 2015–16 expenditures of $59,250 and an assessment rate of $0.10 per hundredweight of dates, which is $0.10 lower than the rate previously in effect. Applying the $0.10 per hundredweight assessment rate to the estimated crop at 29,000,000 pounds (290,000 hundredweight) should provide $29,000 in assessment income. Thus, income derived from handler’s assessments, along with other income and funds from the committee’s authorized reserve, should be adequate funding to meet program expenses. This rule continues in effect the action that decreased the assessment obligation imposed on handlers. Assessments are applied uniformly on all handlers; however, decreasing the assessment rate reduces the burden on handlers. In addition, the committee’s meeting was widely publicized throughout the California date industry, and all interested persons were invited to attend the meetings and encouraged to participate in committee deliberations on all issues. Like all committee meetings, the June 25, 2015, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. 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. 0581–0178, ‘‘Vegetable and Specialty Crop Marketing Orders.’’ No changes in those requirements as a result of this action are necessary. Should any changes become necessary, they would be submitted to OMB for approval. This action imposes no additional reporting or recordkeeping requirements on either small or large Riverside County, California, date 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. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. Comments on the interim rule were required to be received on or before December 28, 2015. No comments were received. Therefore, for reasons given in the interim rule, we are adopting the interim rule as a final rule, without change. To view the interim rule, go to: https://www.regulations.gov/ #!documentDetail;D=AMS-FV-15-00340001. This action also affirms information contained in the interim rule concerning Executive Orders 12866, 12988, 13175, and 13563; the Paperwork Reduction Act (44 U.S.C. Chapter 35); and the EGov Act (44 U.S.C. 101). After consideration of all relevant material presented, it is found that finalizing the interim rule, without change, as published in the Federal Register (80 FR 65886, October 28, 2015) will tend to effectuate the declared policy of the Act.

We are issuing this AD to detect and correct damaged wiring and incorrect installation of the wiring harness and adjacent air ducts, which could lead to wire harness chafing and arcing, possibly resulting in an on-board fire. Since the NPRM was issued, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015–0171, dated August 20, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain ATR— ´ GIE Avions de Transport Regional Model ATR42–500 airplanes, and Model ATR72–102, –202, –212, and –212A airplanes. The MCAI states: An erroneous cockpit indication has been reported on an in-service aeroplane. Subsequent investigation identified chafed wiring between harnesses (2M–2S–6M) and the metallic structure of the cargo lining panel above the electronic rack 90VU shelf. The chafing was most likely the result of incorrect harness installation. In some cases, the bracket, which supports the harnesses, could be incorrectly positioned. Consequently, the wiring harnesses, and in certain configurations, the adjacent air duct, could be incorrectly routed. E:\FR\FM\26FER1.SGM 26FER1

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM was published in the Federal Register on November 24, 2015 (80 FR 
73147). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    There have been reports of Arriel 1E2 engines having experienced 
an uncommanded in-flight shut-down (IFSD) due to an untimely 
activation of the tachometer box shut-off system which was activated 
by the power turbine monitoring function of the tachometer box.
    This condition, if not corrected, could potentially lead to 
further cases of IFSD, possibly resulting in a forced landing.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 73147, November 24, 
2015).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed.

Related Service Information

    Turbomeca S.A. has issued Mandatory Service Bulletin No. 292 77 
0844, Version B, dated July 6, 2015. The service information describes 
procedures for removing pre-TU 369 tachometer boxes.

Costs of Compliance

    We estimate that this AD affects 200 engines installed on 
helicopters of U.S. registry. We also estimate that it will take about 
3 hours per engine to comply with this AD. The average labor rate is 
$85 per hour. Based on these figures, we estimate the cost of this AD 
on U.S. operators to be $51,000.

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 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 this AD:
    (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.
