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 anti-ice piccolo duct failure
reported on CL-600-2B19 (CRJ) aircraft. Although there have been no
failures reported on Challenger aircraft, similar ducts are installed
on the * * * [other] Challenger models.
Upon investigation, it has been determined that ducts manufactured
since June 2000, and installed since 1 August 2000, are susceptible to
cracking due to the process used to drill the holes in the ducts.
These ducts were installed on CL-600-2B16 aircraft, serial numbers
5469 through 5635 in production, but may also have been installed as
replacements on CL-600-1A11, CL-600-2A12 and other CL-600-2B16
aircraft.
Cracking of the wing anti-ice piccolo ducts could result in air
leakage, with an adverse effect on the anti-ice air distribution
pattern and a possible unannunciated insufficient heat condition. As a
result, the airplane flight manual (AFM) instructions have been
revised to provide proper annunciation of an insufficient heat
condition, utilizing existing messages and indications, with
instructions, to the pilot, to leave icing conditions if sufficient
heat cannot be achieved or maintained.
This directive mandates the amendment of the AFM procedures, in
addition to checking the part numbers and serial numbers of the
installed wing anti-ice piccolo ducts and replacing them as necessary.
The unsafe condition is anti-ice system air leakage with a possible
adverse effect on the anti-ice air distribution pattern and anti-ice
capability without annunciation to the flightcrew, and consequent
reduced controllability of the airplane.
ACTIONS AND COMPLIANCE
(f) Unless already done, do the following actions.
(1) For airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and
(c)(4) of this AD: Within 30 days after the effective date of this AD,
revise the Normal and Abnormal Procedures sections of the applicable
Canadair Challenger Airplane Flight Manual (AFM) by inserting a copy
of the applicable temporary revision (TR) listed in Table 2 of this
AD. When the information in the applicable TR is included in the
general revisions of the AFM, the general revisions may be inserted in
the AFM, as applicable, and the TR may be removed.

serial number identified in paragraph 2.C. of the applicable service
bulletin listed in Table 3 of this AD is installed. A review of
airplane maintenance records is acceptable in lieu of this inspection
if the serial number of the duct can be conclusively determined from
that review. If any affected serial number is installed, before
further flight, replace the piccolo duct with a serviceable piccolo
duct that does not have a serial number identified in paragraph 2.C.
of the applicable service bulletin listed in Table 3 of this AD. Do
all actions in accordance with the Accomplishment Instructions of the
applicable service bulletin listed in Table 3 of this AD.

AGENCY: Federal Aviation Administration
(FAA), Department of Transportation (DOT).
ACTION: Final rule.
SUMMARY: We are revising 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:
[S]everal cases of wing anti-ice piccolo duct failure reported on CL-600-2B19
(CRJ) aircraft. Although there have been no failures reported on Challenger
aircraft, similar ducts are installed on the * * * [other] Challenger
models.
* * * * *
Cracking of the wing anti-ice piccolo ducts could result in air leakage,
with an adverse effect on the anti-ice air distribution pattern and a
possible unannunciated insufficient heat condition. * * *
The unsafe condition is anti-ice system air leakage with a possible adverse
effect on the anti-ice air distribution pattern and anti-ice capability
without annunciation to the flightcrew, and consequent reduced controllability
of the airplane. We are issuing this AD to require actions to correct
the unsafe condition on these products.
DATES: This AD becomes effective April 1, 2010.
The Director of the Federal Register approved the incorporation by reference
of certain publications listed in this AD as of April 1, 2010.
On April 28, 2009 (74 FR 12225, March 24, 2009), the Director of the Federal
Register approved the incorporation by reference of certain other publications
listed in this AD.
DATES: This AD becomes effective April 1, 2010.
ADDRESSES: You may examine the AD docket on the Internet at http://

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part
39 to revise an existing AD that applies to certain Model CL-600- 1A11
(CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL- 601-3R,
and CL-604) airplanes. That NPRM was published in the Federal Register
on November 5, 2009 (74 FR 57273), and proposed to revise AD 2009-06-05,
Amendment 39-15841 (74 FR 12225, March 24, 2009). That AD required actions
intended to address an unsafe condition for the products listed above.
Actions Since Issuance of AD 2009-06-05
Since we issued AD 2009-06-05, Bombardier requested that we change paragraphs
(f)(2) and (f)(4) of AD 2009-06-05 to allow compliance within 2,000 flight
hours or 60 months after the effective date of the AD, whichever occurs
first, instead of prior to the accumulation of 2,000 total flight hours
or within 60 months after the effective date of the AD, whichever occurs
first. We agreed and proposed to revise paragraphs (f)(2) and (f)(4) of
AD 2009-06-05 accordingly in the NPRM. The compliance time matches the
intent of Transport Canada Civil Aviation (TCCA) AD CF-2008-18, dated
May 9, 2008, and represents the maximum interval of time allowable for
the affected airplanes to operate safely.
Bombardier also requested that we change Table 2 of AD 2009-06-05 to replace
references to two temporary revisions (TRs): Canadair TR 600/23, dated
August 16, 2006, to the Canadair Challenger Model CL-600- 1A11 Airplane
Flight Manual (AFM); and Canadair TR 600-1/19, dated August 16, 2006,
to the Canadair Challenger Model CL-600-1A11 AFM (Winglets). These two
TRs are approved by TCCA, and should be replaced in AD 2009-06-05 with
references to the following FAA-approved TRs: Canadair TR 600/22, dated
August 16, 2006, to the Canadair Challenger Model CL-600-1A11 AFM; and
Canadair TR 600-1/17, dated August 16, 2006, to the Canadair Challenger
Model CL-600-1A11 AFM (Winglets). We agreed and proposed to revise Table
2 of AD 2009-06-05 accordingly in the NPRM.
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 Change Made to the Manufacturer Name
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.
Explanation of Change to the Alternative Methods of Compliance
We have revised the ``Alternative Methods of Compliance (AMOCs)'' paragraph
(g)(1) in this AD to specify the current contact information.
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 108 products of U.S. registry.
The actions that are required by AD 2009-06-05 and retained in this AD
take about 37 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 $339,660,
or $3,145 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 at http:// 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 the ADDRESSES section. Comments will be available
in the AD docket shortly after receipt.
