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 adopting a new airworthiness directive (AD) for
certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes. This AD requires inspecting to identify the wing anti-ice
ducts (piccolo tubes) in the wing leading edge. For airplanes with
affected piccolo tubes, this AD requires revising the airplane flight
manual (AFM) to introduce new procedures for operation in icing
conditions. The optional implementation of repetitive inspections for
cracks of affected piccolo tubes, and corrective actions if necessary,
terminates the operational limitations. The optional installation of
certain new piccolo tubes terminates both the AFM revision and the
inspections. This AD was prompted by 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
the flight crew, and consequent reduced controllability of the
airplane.
DATES: This AD becomes effective September 7, 2005.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of September 7,
2005.
We must receive comments on this AD by October 24, 2005.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the airworthiness
authority for Canada, notified us that an unsafe condition may exist on
certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes. TCCA advises that it has received reports of failed wing
anti-ice ducts (piccolo tubes) located in the wing leading edge. De-
icing capability was degraded on the wing that had the piccolo tube
damage. Upon investigation, it has been determined that piccolo tubes
manufactured since June 2000 are susceptible to cracking due to the
process used to drill the air distribution holes. Such cracking may
cause 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 (TR) RJ/155,
dated July 5, 2005, to the Canadair Regional Jet Airplane Flight Manual
(AFM), CSP A-012. The TR introduces new procedures for operation in
icing conditions. The TR revises the Operating Limitations and Abnormal
Procedures sections of AFM CSP A-012 to include new procedures for
operation in icing conditions.
Accomplishing the actions specified in the TR is intended to
adequately address the unsafe condition. TCCA mandated the TR and
issued Canadian airworthiness directive CF-2005-26, dated July 11,
2005, to ensure the continued airworthiness of these airplanes in
Canada.
Bombardier has also issued Service Bulletin 601R-30-029, Revision
A, dated July 7, 2005. The service bulletin describes procedures for:
Repetitively inspecting, using fluorescent dye penetrant
methods, the piccolo tubes to detect cracks.
Replacing cracked piccolo tubes with acceptable parts, or
reinstalling cracked piccolo tubes under certain conditions.
Reporting the inspection results to the manufacturer.
FAA's Determination and Requirements of the Proposed AD
This airplane model is manufactured in Canada and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, TCCA has kept the FAA informed of
the situation described above. We have examined TCCA's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for airplanes of this type design that are certificated for
operation in the United States.
Therefore, we are issuing this AD, which requires identifying the
part and serial numbers of the piccolo tubes installed on the airplane.
For airplanes
[[Page 49165]]
with affected piccolo tubes, the AD requires revising the AFM as
specified previously. In addition, the optional implementation of the
repetitive inspection program described previously terminates the
operational limitations, provided operators comply with the exception
described under ``Differences Between the AD and the Service Bulletin/
Canadian Airworthiness Directive.'' The optional installation of
certain new piccolo tubes terminates both the AFM revision and the
repetitive inspections.
Differences Between the AD and the Service Bulletin/Canadian
Airworthiness Directive
The service bulletin specifies contacting the manufacturer for
instructions on how to repair certain conditions, but this AD requires
repair of those conditions using a method approved by the FAA or TCCA
(or its delegated agent). In light of the type of repair required to
address the unsafe condition, and consistent with existing bilateral
airworthiness agreements, we have determined that, for this AD, a
repair approved by the FAA or TCCA is acceptable for compliance with
this AD.
The applicability of the Canadian airworthiness directive specifies
serial numbers 7417 through 7990 inclusive, and 8000 and subsequent.
However, this AD expands that applicability to include additional
airplanes that have been recently identified as having the affected
piccolo tube installed. We have been informed that the Canadian
airworthiness directive and the service bulletin will be revised in the
near future to incorporate this change.
These differences have been coordinated with TCCA.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD; therefore, providing notice and opportunity for public comment
before the AD is issued is impracticable, and good cause exists to make
this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written
data, views, or arguments regarding this AD. Send your comments to an
address listed in the ADDRESSES section. Include ``Docket No. FAA-2005-
22145; Directorate Identifier 2005-NM-148-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD that might
suggest a need to modify it.
We will post all comments we receive, without change, to http://dms.dot.gov
, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of that Web
site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).
You may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78), or you may visit
http://dms.dot.gov.
Examining the Docket
You may examine the AD docket on the Internet at http://dms.dot.gov
, or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT
street address stated in the ADDRESSES section. Comments will be
available in the AD docket shortly after the Docket Management System
receives them.
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.

copy of the TR into the AFM. This TR introduces new procedures for
operation in icing conditions. Operate the airplane according to the
limitations and procedures in the TR. When this TR 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 the TR.
Optional Inspections
(i) For airplanes with an affected or unidentifiable piccolo
tube: The operating limitations and abnormal procedures specified in
the TR, as required by paragraph (h) of this AD, may be removed from
the AFM, provided all requirements of this paragraph have been
satisfied.
(1) A fluorescent dye penetrant inspection for cracks of the
piccolo tubes is done and repeated thereafter within 2,000-flight-
hour intervals in accordance with the service bulletin. An
inspection done before the effective date of this AD in accordance
with Bombardier Service Bulletin 601R-30-029, dated June 17, 2005,
is acceptable for compliance with the requirements of paragraph
(i)(1) of this AD.
(2) All applicable corrective actions are done as specified in
paragraph (k) of this AD.
(3) Applicable inspection reports are submitted as specified in
paragraph (o) of this AD.
AFM Limitations Required for Exceeding Inspection Interval
(j) During any period in which the inspection interval exceeds
2,000 flight hours after the initial inspection specified in
paragraph (i)(1) of this AD, the airplane must be operated under the
limitations and abnormal procedures specified in paragraph (h) of
