ACTION: Final rule.
SUMMARY:
We are superseding an existing airworthiness directive (AD) for the products listed above. This 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. * * *
We are issuing this AD to require actions to correct the unsafe condition on these products.
DATES:
This AD becomes effective April 15, 2010.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 15, 2010.
On December 1, 2008 (73 FR 67363, November 14, 2008), the Director of the Federal Register previously approved the incorporation by reference of certain publications listed in this AD.
On September 7, 2005 (70 FR 49164, August 23, 2005), the Director of the Federal Register previously approved the incorporation by reference of certain other publications listed in this AD.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in theFederal Registeron July 24, 2009 (74 FR 36628), and proposed to supersede AD 2008-23-16, Amendment 39-15737 (73 FR 67363, November 14, 2008). That NPRM proposed to correct an unsafe condition for the specified products.
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 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 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.
Comments
We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.
Explanation of Changes Made to the AD
We have revised this AD to identify the legal name of the manufacturer as published in the most recent type certificate data sheet for the affected airplane models.
We have revised paragraph (j)(5) of this AD to remove reference to Master Minimum Equipment List (MMEL) Entry 30-12-03. However, we have approved operation of the airplane according to MMEL Entry 30-12-03 as a method for complying with the requirements of paragraph (j)(5) of this AD. Operators may contact the Manager, New York ACO, ANE-170, for information regarding the use of MMEL Entry 30-12-03 for compliance with the requirements of paragraph (j)(5) of this AD. We have included a new Note 1 in this AD to specify that guidance on operating the airplane under certain conditions according to the MMEL can be found in MMEL Entry 30-12-03, and have renumbered subsequent notes accordingly.
Conclusion
We reviewed the available data and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.
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 required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD.
Explanation of Change to Costs of Compliance
Since issuance of the NPRM, we have increased the labor rate used in the Costs of Compliance from $80 per work-hour to $85 per work-hour. The Costs of Compliance information, below, reflects this increase in the specified hourly labor rate.
Costs of Compliance
We estimate that this AD will affect about 711 products of U.S. registry.
The actions that are required by AD 2008-23-16 and retained in this AD take about 3 work-hours per product, at an average labor rate of $85 per work hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the currently required actions is $181,305, or $255 per product.
We estimate that it will take about 12 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will 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 this AD to the U.S. operators to be $725,220, or $1,020 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 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 this AD:
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.
Examining the AD Docket
You may examine the AD docket on the Internet athttp://www.regulations.gov;or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is in theADDRESSESsection. Comments will be available in the AD docket shortly after receipt.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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.
2009-22-05Bombardier, Inc.:Amendment 39-16056. Docket No. FAA-2009-0656; Directorate Identifier 2009-NM-038-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective April 15, 2010.
Affected ADs
(b) This AD supersedes AD 2008-23-16, Amendment 39-15737.
Applicability
(c) This AD applies to Bombardier, Inc. 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.
“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
Identification of Affected Piccolo Tubes
(f) Unless already done, for airplanes having S/Ns 7013, 7017, 7037, 7046, 7059, 7076, 7105, 7127, 7151, 7157, 7163, 7174, 7179, 7203, 7204, 7228, 7271, 7347, 7362, 7378, 7417 through 7990 inclusive, 8000 through 8076 inclusive, 8082, 8086, 8090 through 8092 inclusive, 8096 and 8097: Before the airplane accumulates 3,000 total flight hours, or within 14 days after September 7, 2005 (the effective date of AD 2005-17-12, which was superseded by AD 2008-23-16), whichever occurs later, determine whether any affected piccolo tube is installed on the airplane. Affected piccolo tubes are identified in paragraph 1.A. of Bombardier Service Bulletin 601R-30-029, Revision A, dated July 7, 2005. Doing the action required by paragraph (p), (q), (r), (w), or (y) of this AD terminates the requirements of this paragraph.
