The delinquency fee is calculated based on a 360-day year, that is, six percent times the unpaid balance divided by 360 times the number of days unpaid. The NCUA may waive or abate collection of interest, if circumstances warrant. (2) The Act contains specific penalties and other consequences for delinquent payments, including, but not limited to: (i) Section 202(d)(2)(B) of the Act (12 U.S.C. 1782(d)(2)(B)) provides that the Board may assess and collect a penalty from an insured credit union of not more than $20,000 for each day the credit union fails or refuses to pay any deposit or premium due to the fund; and (ii) Section 202(d)(3) of the Act (12 U.S.C. 1782(d)(3)) provides, generally, that no insured credit union shall pay any dividends on its insured shares or distribute any of its assets while it remains in default in the payment of its deposit or any premium charge due to the fund. Section 202(d)(3) further provides that any director or officer of any insured credit union who knowingly participates in the declaration or payment of any such dividend or in any such distribution shall, upon conviction, be fined not more than $1,000 or imprisoned more than one year, or both.

E9–17310 Filed 7–23–09; 8:45 am] BILLING CODE 7535–01–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2009–0656; Directorate Identifier 2009–NM–038–AD] RIN 2120–AA64 Airworthiness Directives; Bombardier Model CL–600–2B19 (Regional Jet Series 100 & 440) Airplanes srobinson on DSKHWCL6B1PROD with PROPOSALS AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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 VerDate Nov<24>2008 16:00 Jul 23, 2009 Jkt 217001 the unsafe condition as: There have been several cases of wing leading edge anti-ice piccolo duct failure reported on CL–600–2B19 (CRJ) aircraft. Upon investigation, it was determined that ducts manufactured since May 2000 are susceptible to cracking due to the process used to drill holes in the ducts. This cracking may cause air leakage, with a possible adverse effect on the anti-ice air distribution pattern and antiice capability, without annunciation to the flight crew [and consequent reduced controllability of the airplane]. It has subsequently been determined that faulty ducts may also have been installed in a number of leading edge assemblies built as spares and whose current locations are not specifically known. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by August 24, 2009.

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 proposed AD. Discussion On November 4, 2008, we issued AD 2008–23–16, Amendment 39–15737 (73 FR 67363, November 14, 2008). That AD required actions intended to address an unsafe condition on the products listed above. The preamble to AD 2008–23–16 explains that we consider those requirements ‘‘interim action’’ and were considering further rulemaking. We now have determined that further rulemaking is indeed necessary to require the previously optional terminating action, and this proposed AD follows from that determination. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, previously issued Canadian Airworthiness Directive CF–2008–30, dated October 7, 2008 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The unsafe condition is cracked piccolo ducts, which could result in air leakage, a possible adverse effect on the anti-ice distribution pattern and anti-ice capability without annunciation to the flight crew, and consequent reduced controllability of the airplane. Required actions include revising the airplane E:\FR\FM\24JYP1.SGM 24JYP1 Federal Register / Vol. 74, No. 141 / Friday, July 24, 2009 / Proposed Rules flight manual, inspecting to determine if certain anti-ice piccolo ducts are installed, and replacing or repairing the piccolo duct if necessary. You may obtain further information by examining the MCAI in the AD docket. 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 $682,560, or $960 per product. FAA’s Determination and Requirements of This 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Authority for This Rulemaking srobinson on DSKHWCL6B1PROD with PROPOSALS Differences Between This 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 711 products of U.S. registry. The actions that are required by AD 2008–23–16 and retained in this proposed AD take about 3 work-hours per product, at an average labor rate of $80 per work hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the currently required actions on U.S. operators is $170, 640, or $240 per product. We estimate that it would take about 12 work-hours per product to comply with the new basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $0 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 VerDate Nov<24>2008 16:00 Jul 23, 2009 Jkt 217001 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 36629 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 removing Amendment 39–15737 (73 FR 67363, November 14, 2008) and adding the following new AD: Bombardier, Inc. (Formerly Canadair): Docket No. FAA–2009–0656; Directorate Identifier 2009–NM–038–AD. Comments Due Date (a) We must receive comments by August 24, 2009. Affected ADs (b) The proposed AD supersedes AD 2008– 23–16, Amendment 39–15737. Applicability (c) This AD applies to Bombardier Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category; serial numbers (S/Ns) 7003 through 7067 inclusive, 7069 through 7990 inclusive, 8000 through 8076 inclusive, 8082, 8086, 8090 through 8092 inclusive, 8096, and 8097. Subject (d) Air Transport Association (ATA) of America Code 30: Ice and rain protection. Reason (e) The mandatory continuing airworthiness information (MCAI) states: There have been several cases of wing leading edge anti-ice piccolo duct failure reported on CL–600–2B19 (CRJ) aircraft. Upon investigation, it was determined that ducts manufactured since May 2000 are susceptible to cracking due to the process used to drill holes in the ducts. This cracking may cause air leakage, with a possible adverse effect on the anti-ice air distribution pattern and anti-ice capability, without annunciation to the flight crew [and consequent reduced controllability of the airplane]. The faulty ducts were installed on aircraft SN 7417 through 7990 and 8000 through 8055 in production, and as replacement parts on in service aircraft SN 7014, 7017, 7037, 7046, 7059, 7076, 7105, 7127, 7151, 7157, 7163, 7179, 7203, 7228, 7271, 7347, 7359, 7362, 7378 and 7381. Service Bulletin (SB) 601R–30–029, Revision B and AD CF–2005– 26R1 previously covered the above aircraft serial numbers. It has subsequently been determined that faulty ducts may also have been installed in a number of leading edge assemblies built as spares and whose current locations are not specifically known. As they may have been installed on any of the aircraft serial numbers in the Applicability section of this directive, checking of records and/or inspection * * * is now required for all applicable aircraft. E:\FR\FM\24JYP1.SGM 24JYP1 36630 Federal Register / Vol. 74, No. 141 / Friday, July 24, 2009 / Proposed Rules This directive, which supersedes and cancels AD CF–2005–26R1 [which corresponds to FAA AD 2005–17–12, amendment 39–14223], mandates the amendment of the Airplane Flight Manual (AFM) procedures, in addition to checking the part numbers and serial numbers of installed and spare wing anti-ice piccolo ducts, as required, and inspecting, replacing or repairing them as necessary. Terminating action is also introduced. Required actions include revising the airplane flight manual, inspecting to determine if certain anti-ice piccolo ducts are installed, and replacing or repairing the piccolo duct if necessary.

Standards for Business Practices for Interstate Natural Gas Pipelines; Notice of Proposed Rulemaking 1. The Federal Energy Regulatory Commission (Commission) proposes to amend its regulations at 18 CFR 284.12 to incorporate by reference the consensus standards adopted by the Wholesale Gas Quadrant (WGQ) of the North American Energy Standards Board (NAESB) that (1) permit the use of indices to price capacity release transactions and (2) afford greater flexibility on the receipt and delivery points for redirects of scheduled gas quantities. I. Background 2. Since 1996, the Commission has adopted regulations to standardize the business practices and communication methodologies of natural gas interstate pipelines to create a more integrated and efficient pipeline grid. These regulations have been promulgated in the Order No. 587 series of orders,1 wherein the Commission has incorporated by reference standards for interstate natural gas pipeline business practices and electronic communications that were developed and adopted by NAESB’s WGQ. Upon incorporation by reference by the Commission, these standards have become a part of the Commission’s regulations and have become mandatory and binding on the natural gas pipelines under the Commission’s jurisdiction. 3. A cold snap in January 2004 in New England highlighted the need for better coordination and communication between the gas and electric industries as coincident peaks occurred in both 1 This series of orders began with the Commission’s issuance of Standards for Business Practices of Interstate Natural Gas Pipelines, Order No. 587, FERC Stats. & Regs. ¶ 31,038 (1996). PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 36633 industries making the acquisition of gas and transportation by power plant operators more difficult. In response to this need, in early 2004, NAESB established a Gas-Electric Coordination Task Force to examine issues related to the interrelationship of the gas and electric industries and identify potential areas for improved coordination through standardization. NAESB developed a number of standards to enhance the coordination of scheduling and other business practices between the gas and electric industries. On June 27, 2005, NAESB filed these standards and requested clarification regarding a number of additional proposals that it was considering, including capacity release indexed pricing, the use of flexible receipt and delivery points upstream of a constraint, and changes to the intra-day nomination cycle. 4. In Order No. 698,2 the Commission incorporated these standards by reference and provided the clarification requested in NAESB’s June 27, 2005 filing. The NAESB report highlighted several issues relating to Commission policy that were inhibiting the development of additional standards and requested Commission guidance and clarification on these issues. In the NOPR 3 and in Order No. 698, the Commission provided clarification and guidance to NAESB regarding Commission policies in the following three areas: (1) Uses of gas indices for pricing capacity release transactions; (2) flexibility in the use of receipt and delivery points; and (3) changes to the intraday nomination schedule to increase the number of scheduling opportunities for firm shippers. 5. On September 3, 2008, NAESB submitted a report to the Commission with respect to these three issues. NAESB reports its membership conducted thirteen subcommittee meetings, many of which were multiday meetings, held in a one year period from June 2007 to July 2008. While the standards discussed related only to gas issues, NAESB states that all interested parties including the Wholesale Electric Quadrant membership were asked to participate and make their perspectives known. Two hundred participants, including many from the electric industry, participated in these meetings. 2 Standards for Business Practices for Interstate Natural Gas Pipelines; Standards for Business Practices for Public Utilities, Order No. 698, FERC Stats. & Regs. ¶ 31,251 (2007), order on clarification and reh’g, Order No. 698–A, 121 FERC ¶ 61,264 (2007). 3 Standards for Business Practices for Interstate Natural Gas Pipelines; Standards for Business Practices for Public Utilities, FERC Stats. & Regs. ¶ 32,609 (2006) (NOPR).

Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional 
Jet Series 100 & 440) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. 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: There have been several cases 
of wing leading edge anti-ice piccolo duct failure reported on CL-600-
2B19 (CRJ) aircraft. Upon investigation, it was determined that ducts 
manufactured since May 2000 are susceptible to cracking due to the 
process used to drill holes in the ducts. This cracking may cause air 
leakage, with a possible adverse effect on the anti-ice air 
distribution pattern and anti-ice capability, without annunciation to 
the flight crew [and consequent reduced controllability of the 
airplane]. It has subsequently been determined that faulty ducts may 
also have been installed in a number of leading edge assemblies built 
as spares and whose current locations are not specifically known.
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by August 24, 2009.

Discussion

    On November 4, 2008, we issued AD 2008-23-16, Amendment 39-15737 
(73 FR 67363, November 14, 2008). That AD required actions intended to 
address an unsafe condition on the products listed above. The preamble 
to AD 2008-23-16 explains that we consider those requirements ``interim 
action'' and were considering further rulemaking. We now have 
determined that further rulemaking is indeed necessary to require the 
previously optional terminating action, and this proposed AD follows 
from that determination. Transport Canada Civil Aviation (TCCA), which 
is the aviation authority for Canada, previously issued Canadian 
Airworthiness Directive CF-2008-30, dated October 7, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products.
    The unsafe condition is cracked piccolo ducts, which could result 
in air leakage, a possible adverse effect on the anti-ice distribution 
pattern and anti-ice capability without annunciation to the flight 
crew, and consequent reduced controllability of the airplane. Required 
actions include revising the airplane

[[Page 36629]]

flight manual, inspecting to determine if certain anti-ice piccolo 
ducts are installed, and replacing or repairing the piccolo duct if 
necessary. You may obtain further information by examining the MCAI in 
the AD docket.

FAA's Determination and Requirements of This 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 the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This 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 711 products of U.S. registry.
    The actions that are required by AD 2008-23-16 and retained in this 
proposed AD take about 3 work-hours per product, at an average labor 
rate of $80 per work hour. Required parts cost about $0 per product. 
Based on these figures, the estimated cost of the currently required 
actions on U.S. operators is $170, 640, or $240 per product.
    We estimate that it would take about 12 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $80 per work-hour. Required parts would cost about $0 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 $682,560, or $960 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

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 FAA amends Sec.  39.13 by removing Amendment 39-15737 (73 FR 
67363, November 14, 2008) and adding the following new AD:

Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2009-0656; 
Directorate Identifier 2009-NM-038-AD.

Comments Due Date

    (a) We must receive comments by August 24, 2009.

Affected ADs

    (b) The proposed AD supersedes AD 2008-23-16, Amendment 39-
15737.

Applicability

    (c) This AD applies to Bombardier Model CL-600-2B19 (Regional 
Jet Series 100 & 440) airplanes, certificated in any category; 
serial numbers (S/Ns) 7003 through 7067 inclusive, 7069 through 7990 
inclusive, 8000 through 8076 inclusive, 8082, 8086, 8090 through 
8092 inclusive, 8096, and 8097.

Subject

    (d) Air Transport Association (ATA) of America Code 30: Ice and 
rain protection.

Reason

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

    There have been several cases of wing leading edge anti-ice 
piccolo duct failure reported on CL-600-2B19 (CRJ) aircraft. Upon 
investigation, it was determined that ducts manufactured since May 
2000 are susceptible to cracking due to the process used to drill 
holes in the ducts. This cracking may cause air leakage, with a 
possible adverse effect on the anti-ice air distribution pattern and 
anti-ice capability, without annunciation to the flight crew [and 
consequent reduced controllability of the airplane].
    The faulty ducts were installed on aircraft SN 7417 through 7990 
and 8000 through 8055 in production, and as replacement parts on in 
service aircraft SN 7014, 7017, 7037, 7046, 7059, 7076, 7105, 7127, 
7151, 7157, 7163, 7179, 7203, 7228, 7271, 7347, 7359, 7362, 7378 and 
7381. Service Bulletin (SB) 601R-30-029, Revision B and AD CF-2005-
26R1 previously covered the above aircraft serial numbers.
    It has subsequently been determined that faulty ducts may also 
have been installed in a number of leading edge assemblies built as 
spares and whose current locations are not specifically known. As 
they may have been installed on any of the aircraft serial numbers 
in the Applicability section of this directive, checking of records 
and/or inspection * * * is now required for all applicable aircraft.

[[Page 36630]]

    This directive, which supersedes and cancels AD CF-2005-26R1 
[which corresponds to FAA AD 2005-17-12, amendment 39-14223], 
mandates the amendment of the Airplane Flight Manual (AFM) 
procedures, in addition to checking the part numbers and serial 
numbers of installed and spare wing anti-ice piccolo ducts, as 
required, and inspecting, replacing or repairing them as necessary. 
Terminating action is also introduced.

Required actions include revising the airplane flight manual, 
inspecting to determine if certain anti-ice piccolo ducts are 
installed, and replacing or repairing the piccolo duct if necessary.

Restatement of Requirements of AD 2005-17-12
