Download as PDF rmajette on PROD1PC64 with PROPOSALS 31202 Federal Register / Vol. 72, No. 108 / Wednesday, June 6, 2007 / Proposed Rules MPCI coverage level—The coverage level percentage you selected in the underlying MPCI policy to which this option is attached. MPCI dollar amount of insurance— The value of the insurance coverage for the unit provided under the MPCI policy (the amount of insurance selected by you for dollar or similar plans of insurance or the amount determined by multiplying the production guarantee (per acre) times the price election, times the number of acres in the unit, times the MPCI coverage level you selected). MPCI indemnity—The indemnity determined for each unit under the MPCI policy to which this option is attached, not including replant and prevented planting indemnities or any indemnity payable under this option. MPCI indemnity factor—A factor determined by dividing the MPCI indemnity by the MPCI dollar amount of insurance for a unit. This factor is used to ensure that the indemnity paid under this option is proportional to the amount of loss and indemnity paid under the MPCI policy. Option Dollar Amount of Insurance— The value of the additional insurance coverage for the unit provided by this option, which is determined by multiplying the option coverage level by the total value of the crop and subtracting the MPCI dollar amount of insurance. Option Coverage Level—The coverage level percentage selected under this option. This percentage effectively becomes the coverage level under the MPCI policy when the losses under such policy exceed the deductible and an indemnity is owed. Total value of the insured crop—The value of the crop that is determined by dividing the MPCI dollar amount of insurance by the MPCI coverage level. 2. This option is only available for insured crops that contain an option coverage level percent in the actuarial documents. 3. To be eligible for this coverage, you must have an MPCI policy in force for the insured crop (or for citrus fruit, citrus trees, and stone fruit, as applicable, the insured type) in accordance with the applicable Crop Provisions for the insured crop. You must choose an option coverage level percentage that is shown in the actuarial documents, by the sales closing date. 4. You must elect this option in writing on or before the crop sales closing date for the crop insured. This option is continuous and will remain in effect for as long as you continue to have a MPCI policy in effect for the insured crop, an option coverage level percent is contained in the actuarial VerDate Aug<31>2005 15:18 Jun 05, 2007 Jkt 211001 documents, or it is cancelled by you or terminated by us on or before the cancellation or termination date, as applicable. 5. This option is not available if you have chosen the Catastrophic Risk Protection (CAT) level of coverage or a price election less than 100 percent. 6. If you elect this option and a MPCI indemnity is paid on any unit, your deductible will disappear in proportion to the amount of such loss and indemnity paid. For example, if you selected a 50 percent MPCI coverage level, select an 85 percent option coverage level, and had a total loss, the amount of indemnity paid under both the MPCI policy and this option would be equal to 85 percent of the total value of the insured crop. The amount of the additional indemnity and related terms and conditions are described below: (a) All acreage of the insured crop insured under your MPCI policy will be covered under this option; (b) The amount of any replant or prevented planting payment that is payable under the MPCI policy will not be affected by this option. (c) An indemnity will be payable under this option only after the underlying MPCI deductible is met and an MPCI indemnity is paid. (d) The total indemnity for each unit (MPCI coverage plus this option) cannot exceed the combination of both the MPCI and option dollar amounts of insurance. (e) Your premium will be determined by: (i) Totaling the MPCI dollar amount of insurance and the option dollar amount of insurance; and (ii) Multiplying the result of section 6(e)(i) by the premium rate for the insured crop applicable to your MPCI coverage level. 7. In addition to the settlement of claim section for the applicable Crop Provisions, your indemnity will be computed on a unit basis as follows: (a) Determine the MPCI indemnity factor; (b) Multiply the MPCI indemnity factor times the Option Dollar Amount of Insurance to determine the indemnity under this option. Example: Assume a policy with one unit; an MPCI coverage level of 50 percent and an option coverage level of 85 percent; 100% share; a $120,000 MPCI dollar amount of insurance; and a $40,000 payable indemnity under the MPCI portion of the policy. Your indemnity would be calculated for each unit as follows: (a) $40,000 loss ÷ by $120,000 MPCI dollar amount of insurance = .33333 MPCI indemnity factor. PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 (b) .33333 MPCI indemnity factor × $84,000 option dollar amount of insurance = $28,000 indemnity under this option. Note: The total unit indemnity is $68,000 ($40,000 MPCI indemnity plus $28,000 option indemnity) Signed in Washington, DC, on May 30, 2007. Eldon Gould, Manager, Federal Crop Insurance Corporation.

AGENCY: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737–600, –700, –700C, –800 and –900 series airplanes. This proposed AD would require inspecting ground blocks GD261 and GD264 for corrosion, measuring the electrical bond resistance between the ground blocks and the airplane structure, separating the ground wires for the fuel boost pump circuit between ground blocks GD261 and GD264, and doing corrective actions if necessary. This proposed AD results from a report of random flashes of the six fuel pump low pressure lights and intermittent operation of the fuel boost pumps. We are proposing this AD to prevent the simultaneous malfunction of all six fuel boost pumps, which could cause the engines to operate on suction feed and potentially flame out.

Discussion We have received a report of random flashes of the six fuel pump low pressure lights and intermittent operation of the fuel boost pumps. This was caused by an electrical ground block with poor continuity to ground. This condition, if not corrected, could cause the engines to operate on suction feed and potentially flame out. Relevant Service Information We have reviewed Boeing Special Attention Service Bulletin 737–28– 1257, dated February 26, 2007. The service bulletin describes procedures for the following actions: • Inspecting ground blocks GD261 and GD264 for corrosion; • Measuring the electrical bond resistance between the ground blocks and the airplane structure; • Separating the fuel boost pump grounds by removing three fuel boost pump ground wires from ground block GD261 and installing them in ground block GD264. • Repairing corrosion damage; and • Replacing the ground block with a new one if any corrosion is found or if the electrical bond resistance exceeds 0.001 ohm. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other airplanes of this same type design. For this reason, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously.

Discussion

    We have received a report of random flashes of the six fuel pump 
low pressure lights and intermittent operation of the fuel boost pumps. 
This was caused by an electrical ground block with poor continuity to 
ground. This condition, if not corrected, could cause the engines to 
operate on suction feed and potentially flame out.

Relevant Service Information

    We have reviewed Boeing Special Attention Service Bulletin 737-28-
1257, dated February 26, 2007. The service bulletin describes 
procedures for the following actions:
     Inspecting ground blocks GD261 and GD264 for corrosion;
     Measuring the electrical bond resistance between the 
ground blocks and the airplane structure;
     Separating the fuel boost pump grounds by removing three 
fuel boost pump ground wires from ground block GD261 and installing 
them in ground block GD264.
     Repairing corrosion damage; and
     Replacing the ground block with a new one if any corrosion 
is found or if the electrical bond resistance exceeds 0.001 ohm.
    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other airplanes 
of this same type design. For this reason, we are proposing this AD, 
which would require accomplishing the actions specified in the service 
information described previously.

Costs of Compliance

    There are about 1,871 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this proposed AD.

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 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 that the proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;

[[Page 31204]]

    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. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

malfunction of all six fuel boost pumps, which could cause the 
engines to operate on suction feed and potentially flame out.
