Discussion We proposed to amend 14 CFR part 39 with an earlier NPRM for the specified products, which was published in the Federal Register on January 8, 2007 (72 FR 676). That earlier NPRM proposed to require actions intended to address the unsafe condition for the products listed above. Since that NPRM was issued, we determined that replacing any type 1 fuel fittings with type 2 fuel fittings, not just leaking type 1 fuel fittings, is needed in order to eliminate future fuel leaks. The Civil Aviation Authority of New Zealand, which is the airworthiness authority for New Zealand, has issued AD DCA/R2000/12, dated June 29, 2006 SUMMARY: We are revising an earlier NPRM for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: To prevent fuel system leaks inspect the bronze/brass hollow threaded fuel line fittings for type and leaks, per Avions Pierre Robin Service Bulletin (SB) No. 86. ADDRESSES: PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 E:\FR\FM\13AUP1.SGM 13AUP1 45184 Federal Register / Vol. 72, No. 155 / Monday, August 13, 2007 / Proposed Rules (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: To prevent fuel system leaks inspect the bronze/brass hollow threaded fuel line fittings for type and leaks, per Avions Pierre Robin Service Bulletin (SB) No. 86. Replace leaking Type 1 fuel line fittings with Type 2 fittings, per SB No. 86, before further flight. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information AVIONS PIERRE ROBIN (current type certificate responsibility with Alpha Aviation Design Limited) has issued Avions Pierre Robin Service Bulletin No. 86, dated July 30, 1980. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. Comments We received no comments on the earlier NPRM. 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. Certain changes described above expand the scope of the earlier NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on the proposed AD. sroberts on PROD1PC70 with PROPOSALS 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 VerDate Aug<31>2005 17:02 Aug 10, 2007 Jkt 211001 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 10 products of U.S. registry. We also estimate that it would take about 1 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 $100 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $1,800, or $180 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 PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 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: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: Alpha Aviation Design Limited (Type Certificate No. A48EU previously held by Apex Aircraft and AVIONS PIERRE ROBIN): Docket No. FAA–2006–26491; Directorate Identifier 2006–CE–76–AD. Comments Due Date (a) We must receive comments by September 12, 2007. Affected ADs (b) None. Applicability (c) This AD applies to Model R2160 airplanes, serial numbers 001 through 191, certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 28: Fuel. Reason (e) The mandatory continuing airworthiness information (MCAI) states: To prevent fuel system leaks inspect the bronze/brass hollow threaded fuel line fittings for type and leaks, per Avions Pierre Robin Service Bulletin (SB) No. 86. Actions and Compliance (f) Unless already done, within the next 25 hours time-in-service after the effective date of this AD, replace the Type 1 fuel line fittings with Type 2 fittings, per Avions Pierre Robin Service Bulletin No. 86 dated July, 1980. FAA AD Differences Note: This AD differs from the MCAI and/ or service information as follows: This AD requires the replacement of the Type 1 fuel line fittings with Type 2 fittings, per Avions Pierre Robin Service Bulletin No. 86 dated E:\FR\FM\13AUP1.SGM 13AUP1 Federal Register / Vol. 72, No. 155 / Monday, August 13, 2007 / Proposed Rules July, 1980. The MCAI required a one-time inspection for leaks and replacement if leaks were found. There was no MCAI action to determine whether leaks developed in the future. The FAA believes that mandatory replacement of the fittings will eliminate current leaking fittings as well as preventing the problem from developing in the future. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Karl Schletzbaum, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329–4146; fax: (816) 329–4090. 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. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120–0056.

SUPPLEMENTARY INFORMATION: I. Introduction The Commodity Futures Trading Commission (Commission) published comprehensive final regulations for trading facilities on August 10, 2001.1 The final regulations codified the procedural provisions common to 1 66 PO 00000 FR 42256 (August 10, 2001).

The final regulations also codified the procedural provisions common to DCMs, derivatives transaction execution facilities (DTEF), and derivatives clearing organizations (DCO) in part 40 of the Commission’s regulations, and further established the regulatory framework necessary to implement and interpret the provisions of the CEA, as amended by the Commodity Futures Modernization Act of 2000 (CFMA),2 pertinent to trading facilities. Based upon its subsequent experience in administering the Act, the Commission herein proposes several amendments to parts 36 and 40 of the Commission’s regulations to better implement the Act and provide clearer direction as to the Commission’s regulatory requirements thereunder. II. Exempt Commercial Markets The CFMA created a qualified exemption from the Commission’s jurisdiction for transactions executed or traded on ECMs. Section 2(h)(3) of the Act, which was added by the CFMA, applies the exemption to transactions in exempt commodities executed or traded on an electronic trading facility that are entered into on a principal-to-principal basis solely between persons that are eligible commercial entities.3 The CEA specifically reserves the applicability of the Commission’s antifraud and antimanipulation authority to transactions executed or traded on ECMs in section 2(h)(4) of the Act 4 and gives the Commission the authority to issue ECM special calls for information to, among other things, enforce that authority.5 In July 2004, the Commission amended regulation 36.3(b), which governs the Commission’s access to ECM transaction data, to improve the quality of accessible information relevant to its antifraud and antimanipulation authority.6 In that rulemaking, the Commission stated that aberrant price behavior on ECMs may require further Commission investigation and the eventual use of the Commission’s special call authority to identify wrongful conduct.7 The authority to issue special calls to ECMs currently is delegated to the Directors of 2 Pub.

SUMMARY: We are revising an earlier NPRM for the products listed above. 
This proposed AD results from mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as:

    To prevent fuel system leaks inspect the bronze/brass hollow 
threaded fuel line fittings for type and leaks, per Avions Pierre 
Robin Service Bulletin (SB) No. 86.

    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

Discussion

    We proposed to amend 14 CFR part 39 with an earlier NPRM for the 
specified products, which was published in the Federal Register on 
January 8, 2007 (72 FR 676). That earlier NPRM proposed to require 
actions intended to address the unsafe condition for the products 
listed above.
    Since that NPRM was issued, we determined that replacing any type 1 
fuel fittings with type 2 fuel fittings, not just leaking type 1 fuel 
fittings, is needed in order to eliminate future fuel leaks.
    The Civil Aviation Authority of New Zealand, which is the 
airworthiness authority for New Zealand, has issued AD DCA/R2000/12, 
dated June 29, 2006

[[Page 45184]]

(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    To prevent fuel system leaks inspect the bronze/brass hollow 
threaded fuel line fittings for type and leaks, per Avions Pierre 
Robin Service Bulletin (SB) No. 86. Replace leaking Type 1 fuel line 
fittings with Type 2 fittings, per SB No. 86, before further flight.

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

Relevant Service Information

    AVIONS PIERRE ROBIN (current type certificate responsibility with 
Alpha Aviation Design Limited) has issued Avions Pierre Robin Service 
Bulletin No. 86, dated July 30, 1980. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

Comments

    We received no comments on the earlier NPRM.

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.
    Certain changes described above expand the scope of the earlier 
NPRM. As a result, we have determined that it is necessary to reopen 
the comment period to provide additional opportunity for the public to 
comment on the proposed AD.

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 10 products of U.S. registry. We also estimate that 
it would take about 1 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 $100 per product. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these costs. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $1,800, or $180 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.

    (c) This AD applies to Model R2160 airplanes, serial numbers 001 
through 191, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 28: Fuel.

Reason

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

    To prevent fuel system leaks inspect the bronze/brass hollow 
threaded fuel line fittings for type and leaks, per Avions Pierre 
Robin Service Bulletin (SB) No. 86.

Actions and Compliance

    (f) Unless already done, within the next 25 hours time-in-
service after the effective date of this AD, replace the Type 1 fuel 
line fittings with Type 2 fittings, per Avions Pierre Robin Service 
Bulletin No. 86 dated July, 1980.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: This AD requires the replacement of the Type 1 fuel line 
fittings with Type 2 fittings, per Avions Pierre Robin Service 
Bulletin No. 86 dated

[[Page 45185]]

July, 1980. The MCAI required a one-time inspection for leaks and 
replacement if leaks were found. There was no MCAI action to 
determine whether leaks developed in the future. The FAA believes 
that mandatory replacement of the fittings will eliminate current 
leaking fittings as well as preventing the problem from developing 
in the future.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Staff, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send

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.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act (44 
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
