(7) Multiplying the result of section
12(b)(6) by your share.
For example: You have a 100 percent
share in 100 harvested acres of potatoes
in the unit, with a guarantee of 150
hundredweight per acre and a price
election of $4.00 per hundredweight.
You are only able to harvest 10,000
hundredweight. Your indemnity would
be calculated as follows:
(1) 100 acres × 150 hundredweight =
15,000 hundredweight guarantee;
(2) 15,000 hundredweight × $4.00
price election = $60,000.00 value of
guarantee;
(4) 10,000 hundredweight × $4.00
price election = $40,000.00 value of
production to count;
(5) $60,000.00 ¥ $40,000.00 =
$20,000.00 loss; and
(6) $20,000.00 × 100 percent =
$20,000.00 indemnity payment.
You also have a 100 percent share in
100 unharvested acres of potatoes in the
same unit, with a guarantee of 150
hundredweight per acre and a price
election of $3.60 per hundredweight.
(The price election for unharvested
acreage is 90.0 percent of your elected
price election ($4.00 × 0.90 = $3.60.))
This unharvested acreage was appraised
at 35 hundredweight per acre for a total
of 3500 hundredweight as production to
count. Your total indemnity for the
harvested and unharvested acreage
would be calculated as follows:
(1) 100 acres × 150 hundredweight =
15,000 hundredweight guarantee for the
harvested acreage, and

of guarantee for the harvested acreage,
and
15,000 hundredweight guarantee ×
$3.60 price election = $54,000.00 value
of guarantee for the unharvested
acreage;
(3) $60,000.00 + $54,000.00 =
$114,000.00 total value of guarantee;
(4) 10,000 hundredweight × $4.00

production to count for the harvested
acreage, and 3500 hundredweight ×
$3.60 = $12,600.00 value of production
to count for the unharvested acreage;
(5) $40,000.00 + $12,600.00 =
$52,600.00 total value of production to
count;
(6) $114,000.00 ¥ $52,600.00 =
$61,400.00 loss; and

(iv) Unharvested production,
including unharvested production on
insured acreage you intend to put to
another use or abandon, or acreage
damaged by insurable causes and for
which you cease to provide further care,
if you and we agree on the appraised
amount of production. Upon such
agreement, the insurance period for that
acreage will end when you put the
acreage to another use or cease
providing care for the crop. This
unharvested production may be
adjusted in accordance with sections
12(e), and the value of all unharvested
production will be calculated using the
reduced price election determined in

production specified in 12(e)(1):
(1) Production not meeting the
standards for grading U.S. No. 2 due to
external defects will be determined on
an individual basis for all harvested and
unharvested potatoes if we determine it
is or would be practical to separate the
damaged production;
(2) All determinations must be based
upon a grade inspection; and
(3) Prior to any grade inspection, you
must notify us of the intended use of the
potatoes so the appropriate United
States Standard will be applied (We
may request previous sales records to
PO 00000

verify your claimed intended use or
base the intended use on the type of
potato grown if such potatoes are not
usually grown for the intended use you
reported).
(4) Marketable lots of potatoes will
include any lot of potatoes that is:
(i) Stored;
(ii) Sold as seed;
(iii) Sold for human consumption; or
(iv) Harvested and not sold or that is
appraised if such lots meet the
standards for grading U.S. No. 2 grade
or better on a sample basis.
(5) Marketable lots will also include
any potatoes that we determine:
(i) Could have been sold for seed or
human consumption in the general
marketing area;
(ii) Were not sold as a result of
uninsured causes including, but not
limited to, failure to meet chipper or
processor standards for fry color or
specific gravity; or
(iii) Were disposed of without our
prior written consent and such
disposition prevented our determination
of marketability.
(6) Unless included in section 12(e)(4)
or (5), a potato lot will not be
considered marketable if, due to
insurable causes of damage, it:
(i) Is partially damaged, and is
salvageable only for starch, alcohol, or
livestock feed;
(ii) Does not meet the standards for
grading U.S. No. 2 grade or better due
to internal defects; or
(iii) Does not meet the standards for
grading U.S. No. 2 grade or better due
to external defects, and it is not
practical to separate the damaged
production.

ACTION:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Bombardier Model DHC–8–400 series
airplanes. This AD requires an
inspection to detect discrepancies of the
main landing gear (MLG) system, an
inspection of the jam nut of the retract
actuator of the MLGs to ensure the wire
lock is in place and the nut is secured,
an inspection of the retract actuator for
any signs of corrosion or wear, and
applicable related investigative and
corrective actions if necessary. This AD
also requires submitting an inspection
report to Bombardier. This AD results
from two reports of collapse of MLGs
within a few days of each other. We are
issuing this AD to detect and correct
potential failure of major components of
the MLG assembly and attachments,
which could result in the possible
collapse of a MLG and consequent
damage to the airplane and injury to
people or damage to property on the
ground.
This AD becomes effective
November 14, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of November 14, 2007.
We must receive comments on this
AD by November 29, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation
(TCCA), which is the airworthiness
authority for Canada, notified us that an
unsafe condition may exist on certain
Bombardier Model DHC–8–400 series
airplanes. TCCA advises that, on
September 9, 2007, a main landing gear
(MLG) collapsed on a Bombardier
Model DHC–8–400 series airplane
during landing, and that two days later
on September 11, 2007, another MLG
collapsed on a Bombardier Model DHC–
8–400 series airplane during landing. It
has been determined that the root cause
of both MLG failures was a failure of the
retract actuator during gear extension.
This failure allowed the gear to fall
unrestricted with sufficient force to
break the over-center drag strut. The
reason for the component failure was
determined to be caused by internal
corrosion of the threads at the rod end
of the retract actuator. Potential failure
of the major components of the MLG
assembly and attachments, if not
corrected, could result in the possible
collapse of the MLG and consequent
damage to the airplane and injury to
people or damage to property on the
ground.
Relevant Service Information
Bombardier has issued DHC–8 Series
400 Maintenance Requirements Manual
(PSM 1–84–7), Part 1 (Maintenance
Review Board Report), tasks Z700–03E
(left hand) and Z700–04E (right hand).
These tasks describe procedures for
doing a general visual inspection to
detect discrepancies of the left- and
right-hand MLG systems.
Bombardier also has issued Repair
Drawing (RD) 8/4–32–059, Issue 4,
dated September 14, 2007. Bombardier
RD 8/4–32–059 refers to Goodrich
Service Concession Request SCR 086–
07, Revision C, dated September 14,
2007, as an additional source of service
information for accomplishing the
procedures in the RD. These documents
describe procedures for doing an
inspection of the retract actuator for any
PO 00000
Frm 00017
Fmt 4700
Sfmt 4700
61289
signs of corrosion or wear, and doing
applicable corrective actions if
necessary, which include adjusting the
retracted length of the rod end, torquing
the jam nut, installing a wire lock, and
lubricating the piston if necessary.
These documents also describe
procedures for doing a detailed
inspection of affected parts for any signs
of corrosion or wear, and doing
applicable related investigative and
corrective actions if necessary. The
related investigative actions involve
visually inspecting the threads of the
piston pin and the thread relief area for
evidence of corrosion. The corrective
actions include, but are not limited to,
removing the wire lock, backing off the
jam nut and rod end out of the piston,
replacing any discrepant retract actuator
or actuator assembly, coating certain
parts with a corrosion inhibitor
compound, and reworking any corroded
threaded area of the piston.
TCCA mandated the RD and
Bombardier DHC–8 Series 400
Maintenance Requirements Manual
(PSM 1–84–7), Part 1 (Maintenance
Review Board Report), tasks Z700–03E
(left hand) and Z700–04E (right hand),
and issued Canadian airworthiness
directive CF–2007–20, dated September
12, 2007, to ensure the continued
airworthiness of these airplanes in
Canada.
FAA’s Determination and Requirements
of this AD
These airplanes are manufactured in
Canada and are type certificated for
operation in the United States under the
provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement. Pursuant to
this bilateral airworthiness agreement,
TCCA has kept the FAA informed of the
situation described above. We have
examined TCCA’s findings, evaluated
all pertinent information, and
determined that we need to issue an AD
for products of this type design that are
certificated for operation in the United
States.
Therefore, we are issuing this AD to
detect and correct potential failure of
major components of the MLG assembly
and attachments, which could result in
the possible collapse of a MLG and
consequent damage to the airplane and
injury to people or damage to property
on the ground. This AD requires doing
a general visual inspection to detect
discrepancies of the left- and right-hand
MLG systems, doing a general visual
inspection of the jam nut of the retract
actuator of the left- and right-hand
MLGs to ensure the wire lock is in place
and the nut is secured, doing a detailed
E:\FR\FM\30OCR1.SGM
30OCR1
61290
Federal Register / Vol. 72, No. 209 / Tuesday, October 30, 2007 / Rules and Regulations
inspection of the retract actuator for any
signs of corrosion or wear, and doing
applicable related investigative and
corrective actions if necessary. This AD
also requires reporting the inspection
results to Bombardier.
Interim Action
We consider this AD interim action.
The inspection reports that are required
by this AD will enable the manufacturer
to obtain better insight into the nature,
cause, and extent of the problem, and
eventually to develop final action to
address the unsafe condition. Once final
action has been identified, we might
consider further rulemaking.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD; therefore, providing notice and
opportunity for public comment before
the AD is issued is impracticable, and
good cause exists to make this AD
effective in less than 30 days.

This AD is a final rule that involves
requirements affecting flight safety, and
we did not provide you with notice and
an opportunity to provide your
comments before it becomes effective.
However, we invite you to send any
written data, views, or arguments about
this AD. Send your comments to an
address listed under the ADDRESSES
section. Include ‘‘Docket No. FAA–
2007–29235; Directorate Identifier
2007–NM–232–AD’’ at the beginning of
your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of this AD. We will consider all
comments received by the closing date
and may amend this AD because of
those comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each

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
VerDate Aug<31>2005
17:42 Oct 29, 2007
Jkt 214001
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.
Effective Date
(a) This AD becomes effective November
14, 2007.
Regulatory Findings
Unsafe Condition
(d) This AD results from two reports of
collapse of the main landing gear (MLG)
within a few days of each other. We are
issuing this AD to detect and correct
potential failure of major components of the
MLG assembly and attachments, which could
result in the possible collapse of the MLG
and consequent damage to the airplane and
injury to people or damage to property on the
ground.
We have 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 that the 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); 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 AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the airworthiness
authority for Canada, notified us that an unsafe condition may exist on
certain Bombardier Model DHC-8-400 series airplanes. TCCA advises that,
on September 9, 2007, a main landing gear (MLG) collapsed on a
Bombardier Model DHC-8-400 series airplane during landing, and that two
days later on September 11, 2007, another MLG collapsed on a Bombardier
Model DHC-8-400 series airplane during landing. It has been determined
that the root cause of both MLG failures was a failure of the retract
actuator during gear extension. This failure allowed the gear to fall
unrestricted with sufficient force to break the over-center drag strut.
The reason for the component failure was determined to be caused by
internal corrosion of the threads at the rod end of the retract
actuator. Potential failure of the major components of the MLG assembly
and attachments, if not corrected, could result in the possible
collapse of the MLG and consequent damage to the airplane and injury to
people or damage to property on the ground.
Relevant Service Information
Bombardier has issued DHC-8 Series 400 Maintenance Requirements
Manual (PSM 1-84-7), Part 1 (Maintenance Review Board Report), tasks
Z700-03E (left hand) and Z700-04E (right hand). These tasks describe
procedures for doing a general visual inspection to detect
discrepancies of the left- and right-hand MLG systems.
Bombardier also has issued Repair Drawing (RD) 8/4-32-059, Issue 4,
dated September 14, 2007. Bombardier RD 8/4-32-059 refers to Goodrich
Service Concession Request SCR 086-07, Revision C, dated September 14,
2007, as an additional source of service information for accomplishing
the procedures in the RD. These documents describe procedures for doing
an inspection of the retract actuator for any signs of corrosion or
wear, and doing applicable corrective actions if necessary, which
include adjusting the retracted length of the rod end, torquing the jam
nut, installing a wire lock, and lubricating the piston if necessary.
These documents also describe procedures for doing a detailed
inspection of affected parts for any signs of corrosion or wear, and
doing applicable related investigative and corrective actions if
necessary. The related investigative actions involve visually
inspecting the threads of the piston pin and the thread relief area for
evidence of corrosion. The corrective actions include, but are not
limited to, removing the wire lock, backing off the jam nut and rod end
out of the piston, replacing any discrepant retract actuator or
actuator assembly, coating certain parts with a corrosion inhibitor
compound, and reworking any corroded threaded area of the piston.
TCCA mandated the RD and Bombardier DHC-8 Series 400 Maintenance
Requirements Manual (PSM 1-84-7), Part 1 (Maintenance Review Board
Report), tasks Z700-03E (left hand) and Z700-04E (right hand), and
issued Canadian airworthiness directive CF-2007-20, dated September 12,
2007, to ensure the continued airworthiness of these airplanes in
Canada.
FAA's Determination and Requirements of this AD
These airplanes are manufactured in Canada and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, TCCA has kept the FAA informed of
the situation described above. We have examined TCCA's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for products of this type design that are certificated for
operation in the United States.
Therefore, we are issuing this AD to detect and correct potential
failure of major components of the MLG assembly and attachments, which
could result in the possible collapse of a MLG and consequent damage to
the airplane and injury to people or damage to property on the ground.
This AD requires doing a general visual inspection to detect
discrepancies of the left- and right-hand MLG systems, doing a general
visual inspection of the jam nut of the retract actuator of the left-
and right-hand MLGs to ensure the wire lock is in place and the nut is
secured, doing a detailed
[[Page 61290]]
inspection of the retract actuator for any signs of corrosion or wear,
and doing applicable related investigative and corrective actions if
necessary. This AD also requires reporting the inspection results to
Bombardier.
Interim Action
We consider this AD interim action. The inspection reports that are
required by this AD will enable the manufacturer to obtain better
insight into the nature, cause, and extent of the problem, and
eventually to develop final action to address the unsafe condition.
Once final action has been identified, we might consider further
rulemaking.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD; therefore, providing notice and opportunity for public comment
before the AD is issued is impracticable, and good cause exists to make
this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
``Docket No. FAA-2007-29235; Directorate Identifier 2007-NM-232-AD'' at
the beginning of your comments. We specifically invite comments on the
overall regulatory, economic, environmental, and energy aspects of this
AD. We will consider all comments received by the closing date and may
amend this AD because of those comments.
We will post all comments we receive, without change, to https://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this 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 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 that the 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); 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
