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

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) that applies to certain Bombardier Model CL-600-2B19 (Regional Jet 
Series 100 & 440) airplanes. The existing AD currently requires 
inspecting to identify the wing anti-ice ducts (piccolo tubes) in the 
wing leading edge. For airplanes with affected piccolo tubes, the 
existing AD requires revising the airplane flight manual (AFM) to 
introduce new procedures for operation in icing conditions. The 
existing AD provides an optional implementation of repetitive 
inspections for cracks of affected piccolo tubes, and corrective 
actions if necessary, which terminates the operational limitations. The 
existing AD also provides an optional installation of certain new 
piccolo tubes, which terminates both the AFM revision and the 
inspections. This AD adds airplanes to the applicability, requires 
revising the AFM to introduce new procedures for operation in icing 
conditions, and requires inspecting to determine if certain anti-ice 
piccolo ducts are installed, and replacing or repairing the piccolo 
duct if necessary. This AD also provides an optional terminating action 
of replacing all affected piccolo ducts. This AD results from reports 
of failed piccolo tubes. We are issuing this AD to prevent cracked 
piccolo tubes, which could result in air leakage, a possible adverse 
effect on the anti-ice air distribution pattern and anti-ice capability 
without annunciation to

[[Page 67364]]

the flight crew, and consequent reduced controllability of the 
airplane.

DATES: This AD becomes effective December 1, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of December 1, 
2008.
    On September 7, 2005 (70 FR 49164, August 23, 2005), the Director

SUPPLEMENTARY INFORMATION:

Discussion

    On August 11, 2005, the FAA issued AD 2005-17-12, amendment 39-
14223 (70 FR 49164, August 23, 2005). That AD applies to certain 
Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. 
That AD requires inspecting to identify the wing anti-ice ducts 
(piccolo tubes) in the wing leading edge. For airplanes with affected 
piccolo tubes, that AD requires revising the airplane flight manual 
(AFM) to introduce new procedures for operation in icing conditions. 
That AD provides an optional implementation of repetitive inspections 
for cracks of affected piccolo tubes, and corrective actions if 
necessary, which terminates the operational limitations. That AD also 
provides an optional installation of certain new piccolo tubes, which 
terminates both the AFM revision and the inspections. That AD resulted 
from reports of failed piccolo tubes. The actions specified in that AD 
are intended to prevent cracked piccolo tubes, which could result in 
air leakage, 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.

Actions Since AD Was Issued

    Since we issued AD 2005-17-12, we received a report that faulty 
piccolo tubes might have been installed in a number of leading edge 
assemblies built as spares, and whose current locations are not 
specifically known. These faulty parts may have been installed on 
airplanes affected by that AD. Faulty piccolo tubes could crack, which 
could result in air leakage, 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.

Relevant Service Information

    Bombardier has issued Canadair Temporary Revision RJ/155-6, dated 
September 17, 2008 (``the TR''), to the Canadair Regional Jet AFM, CSP 
A-012. The TR describes new procedures for operation in icing 
conditions and supersedes Canadair TR RJ/155, dated July 5, 2005 (which 
we referred to as the appropriate source of service information for 
doing the AFM revision required by AD 2005-17-12).
    Bombardier has also issued Service Bulletin 601R-30-029, Revision 
B, dated August 29, 2005. We referred to Bombardier Service Bulletin 
601R-30-029, Revision A, dated July 7, 2005, as the appropriate source 
of service information for doing certain actions required by AD 2005-
17-12. Revision B contains the same procedures as Revision A but adds 
airplanes to the effectivity and removes certain other airplanes from 
the effectivity.
    Bombardier has also issued Alert Service Bulletin A601R-30-032, 
dated September 18, 2008. This service bulletin supersedes Bombardier 
Service Bulletin 601R-30-029, Revision A, dated July 7, 2005. 
Bombardier Alert Service Bulletin A601R-30-032 describes procedures for 
inspecting to determine if certain anti-ice piccolo ducts are 
installed, and replacing or repairing the piccolo duct if necessary.
    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. Transport Canada 
Civil Aviation (TCCA) mandated the service information and issued 
Canadian airworthiness directive CF-2008-30, dated October 7, 2008 
(referred to after this as ``the MCAI''), to ensure the continued 
airworthiness of these airplanes in Canada. Canadian airworthiness 
directive CF-2008-30 supersedes Canadian airworthiness directive CF-
2005-26R1, dated September 21, 2005, and adds airplanes to the 
applicability. We referred to Canadian airworthiness directive CF-2005-
26, dated July 11, 2005, in our AD 2005-17-12.

FAA's Determination and Requirements of This 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 issuing 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.
    Therefore, we are issuing this AD to supersede AD 2005-17-12. This 
new AD retains certain requirements of the existing AD. This AD also 
requires accomplishing the actions specified in the service information 
described previously, except as discussed under ``Differences Between 
the AD and the Service Information.'' This AD also adds airplanes to 
the applicability and removes certain other airplanes from the 
applicability.

Differences Between the AD and the Service Information

    Where Bombardier Alert Service Bulletin A601R-30-032, dated 
September 18, 2008, specifies that Bombardier may be contacted for 
information regarding repair, this AD

[[Page 67365]]

requires repair according to a method approved by either the Manager, 
New York ACO, or TCCA (or its delegated agent).

Interim Action

    We consider this AD interim action. We are currently considering 
requiring the replacement of all piccolo ducts that have serial numbers 
identified in Part A, Paragraph 2.A., of the Accomplishment 
Instructions of Bombardier Alert Service Bulletin A601R-30-032, dated 
September 18, 2008, with piccolo ducts that do not have the affected 
serial numbers, which will constitute terminating action for the 
actions required by this AD. However, the planned compliance time for 
the replacement would allow enough time to provide notice and 
opportunity for prior public comment on the merits of the replacement.

FAA's Justification and Determination of the Effective Date

    Because of our requirement to promote safe flight of civil aircraft 
and thus, the critical need to ensure proper functioning of the anti-
ice systems during the upcoming winter season, and the short compliance 
time involved with this action, this AD must be issued immediately.
    Because an unsafe condition exists that requires the immediate 
adoption of this AD, we find that notice and opportunity for prior 
public comment hereon are impracticable and that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2008-1200; Directorate Identifier 2008-NM-178-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 have 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 that the 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

New Requirements of This AD

New Revision to AFM

    (n) For all airplanes: Within 14 days after the effective date 
of this AD, revise the Operating Limitations and Abnormal Procedures 
sections of the Canadair Regional Jet AFM, CSP A-012, to include the 
information in Canadair (Bombardier) TR RJ/155-6, dated September 
17, 2008, as specified in that TR. This may be done by inserting a 
copy of Canadair (Bombardier) TR RJ/155-6 into the AFM. This TR 
introduces new procedures for operation in icing conditions. After 
the AFM revision specified in this paragraph has been done, the AFM 
limitation required by paragraph (g) of this AD must be removed from 
the AFM.

    Note 1: When Canadair (Bombardier) TR RJ/155-6, dated September 
17, 2008, has been included in general revisions of the AFM, the 
general revisions may be inserted in the AFM, provided the relevant 
information in the general revision is identical to that in Canadair 
(Bombardier) TR RJ/155-6.

    (o) Before further flight after accomplishing paragraph (n) of 
this AD, operate the airplane according to the limitations and 
procedures in Canadair (Bombardier) TR RJ/155-6, dated September 17, 
2008, except that MMEL entry 30-12-03, which permits the wing anti-
ice system to be inoperative with specific provisions, is not 
affected by this AD.
