This amount will be considered production to count in determining any final indemnity on the unit and will be used to settle your claim as described in section 13. (ii) You may use such acreage for any purpose, including planting and separately insuring any other crop if such insurance is available. (iii) If you elect to plant and elect to insure spring planted acreage of the same dry pea type (you must elect whether or not you want insurance on the spring planted acreage of the same dry pea type at the time we release the fall planted acreage), you must pay additional premium for the insurance. Such acreage will be insured in accordance with the policy provisions that are applicable to acreage that is initially planted in the spring to the same dry pea type, and you must: (A) Plant the spring planted acreage in a manner which results in a clear and discernible break in the planting pattern at the boundary between it and any remaining acreage of the fall planted dry pea acreage; and (B) Store or market the production in a manner which permits us to verify the amount of spring planted production separately from any fall planted production. In the event you are unable to provide records of production that are acceptable to us, the spring planted acreage will be considered to be a part of the original fall planted unit. * * * * * Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2008–0034; Directorate Identifier 2007–CE–097–AD] RIN 2120–AA64 Airworthiness Directives; Pacific Aerospace Limited Model 750XL Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT).

Relevant Service Information Pacific Aerospace Corporation Limited has issued Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have 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 and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the proposed AD. rfrederick on PROD1PC67 with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 7 products of U.S. registry. We also estimate that it would take about 0.5 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $30 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $490, or $70 per product. Authority for This Rulemaking 15:11 Jan 17, 2008 Jkt 214001 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); 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. 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: § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 Pacific Aerospace Limited: Docket No. FAA– 2008–0034; Directorate Identifier 2007– CE–097–AD. Comments Due Date (a) We must receive comments by February 19, 2008. Affected ADs (b) or None. Applicability (c) This AD applies to Model 750XL airplanes, serial numbers 102 through 134, certificated in any category. Note 1: The applicability of this AD takes precedence over Pacific Aerospace Corporation Limited Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004. Subject (d) Air Transport Association of America (ATA) Code 39: Electrical Wiring. Reason (e) The mandatory continuing airworthiness information (MCAI) states: DCA/750XL/3A is prompted by a report from the manufacturer of the possibility that wiring loom protective sleeving is not fitted to aircraft S/N 107 through to 134. AD applicability revised to include aircraft up to S/N 134. To prevent fretting damage to the wiring loom that may lead to arcing in proximity to the fuel vent lines and the possibility of fire, inspect the main wiring loom on the right hand side of the aircraft adjacent to the frames at station 114.34’’ and 118.84’’, per PACSB/XL/009, issue 2, to ensure that two pieces of protective sleeving are fitted. The effectivity of the service information is serial number (S/N) 102 through 106. The MCAI expanded the applicability to S/N 102 through 134. Actions and Compliance (f) Unless already done, do the following actions: (1) Within the next 100 hours time-inservice (TIS) after the effective date of this AD, inspect the main wiring loom on the right hand side of the aircraft adjacent to the frames at station 114.34’’ and 118.84’’ to ensure there are two pieces of protective sleeving installed following Pacific Aerospace Corporation Limited Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004. (2) If the protective sleeves are missing, install protective sleeves following Pacific Aerospace Corporation Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004. FAA AD Differences Authority: 49 U.S.C. 106(g), 40113, 44701. 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 VerDate Aug<31>2005 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. Note 2: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, E:\FR\FM\18JAP1.SGM 18JAP1 Federal Register / Vol. 73, No. 13 / Friday, January 18, 2008 / Proposed Rules FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Discussion The FAA has examined the underlying safety issues involved in fuel tank explosions on several large transport airplanes, including the adequacy of existing regulations, the service history of airplanes subject to those regulations, and existing maintenance practices for fuel tank systems. As a result of those findings, we issued a regulation titled ‘‘Transport Airplane Fuel Tank System Design Review, Flammability Reduction and Maintenance and Inspection Requirements’’ (66 FR 23086, May 7, 2001). In addition to new airworthiness standards for transport airplanes and new maintenance requirements, this rule included Special Federal Aviation Regulation No. 88 (‘‘SFAR 88,’’ Amendment 21–78, and subsequent Amendments 21–82 and 21–83). Among other actions, SFAR 88 requires certain type design (i.e., type certificate (TC) and supplemental type certificate (STC)) holders to substantiate that their fuel tank systems can prevent ignition sources in the fuel tanks. This requirement applies to type design holders for large turbine-powered transport airplanes and for subsequent modifications to those airplanes. It requires them to perform design reviews and to develop design changes and maintenance procedures if their designs do not meet the new fuel tank safety standards. As explained in the preamble to the rule, we intended to adopt airworthiness directives to mandate any changes found necessary to address E:\FR\FM\18JAP1.SGM 18JAP1

Discussion

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for New Zealand, has issued AD DCA/750XL/3A, dated November 
28, 2007 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    DCA/750XL/3A is prompted by a report from the manufacturer of 
the possibility that wiring loom protective sleeving is not fitted 
to aircraft S/N 107 through to 134. AD applicability revised to 
include aircraft up to S/N 134.
    To prevent fretting damage to the wiring loom that may lead to 
arcing in proximity to the fuel vent lines and the possibility of 
fire, inspect the main wiring loom on the right hand side of the 
aircraft adjacent to the frames at station 114.34'' and 118.84'', 
per PACSB/XL/009 issue 2, to ensure that two pieces of protective 
sleeving are fitted.

    The effectivity of the service information is serial number (S/N) 
102 through 106. The MCAI expanded the applicability to S/N 102 through 
134.

[[Page 3418]]

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Pacific Aerospace Corporation Limited has issued Mandatory Service 
Bulletin PACSB/XL/009, issue 2, revised July 23, 2004. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have 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 and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 7 products of U.S. registry. We also estimate that 
it would take about 0.5 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $30 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $490, or $70 per product.

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); 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.

    (d) Air Transport Association of America (ATA) Code 39: 
Electrical Wiring.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    DCA/750XL/3A is prompted by a report from the manufacturer of 
the possibility that wiring loom protective sleeving is not fitted 
to aircraft S/N 107 through to 134. AD applicability revised to 
include aircraft up to S/N 134.
    To prevent fretting damage to the wiring loom that may lead to 
arcing in proximity to the fuel vent lines and the possibility of 
fire, inspect the main wiring loom on the right hand side of the 
aircraft adjacent to the frames at station 114.34'' and 118.84'', 
per PACSB/XL/009, issue 2, to ensure that two pieces of protective 
sleeving are fitted.

    The effectivity of the service information is serial number (S/
N) 102 through 106. The MCAI expanded the applicability to S/N 102 
through 134.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within the next 100 hours time-in-service (TIS) after the 
effective date of this AD, inspect the main wiring loom on the right 
hand side of the aircraft adjacent to the frames at station 114.34'' 
and 118.84'' to ensure there are two pieces of protective sleeving 
installed following Pacific Aerospace Corporation Limited Mandatory 
Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004.
    (2) If the protective sleeves are missing, install protective 
sleeves following Pacific Aerospace Corporation Mandatory Service 
Bulletin PACSB/XL/009, issue 2, revised July 23, 2004.
