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

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)

ACTION: Notice of proposed rulemaking
(NPRM).
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.
DATES: We must receive comments on
this proposed AD by July 23, 2007.

Management System receives them.
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.

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.
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. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Boeing: Docket No. FAA-2007-28355; Directorate Identifier 2007-NM-
062-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by July 23,
2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Boeing Model 737-600, -700, -700C, -800
and -900 series airplanes, certificated in any category, as
identified in Boeing Special Attention Service Bulletin 737-28-1257,
dated February 26, 2007.
Unsafe Condition
(d) This 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 issuing 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.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspection
(f) Within 24 months after the effective date of this AD: Do a
general visual inspection of ground blocks GD261 and GD264 for
corrosion, measure the electrical bond resistance, and separate the
ground wires for the fuel boost pump circuit between ground blocks
GD261 and GD264. Do these actions in accordance with the
Accomplishment Instructions of Boeing Special Attention Service
Bulletin 737-28-1257, dated February 26, 2007. Do applicable
corrective actions before further flight in accordance with the
service bulletin.
Alternative Methods of Compliance (AMOCs)
(g)(1) The Manager, Seattle Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
(2) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
