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. 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
:During flight-testing of a wing anti-ice piccolo tube
containing a deliberate small breach, it was determined that the
wing leading edge thermal switches were not detecting the consequent
bleed leak at the design threshold. As a result, new Airworthiness
Limitation tasks, consisting of a functional test of the wing
leading edge thermal switches and an inspection of the wing anti-ice
duct piccolo tubes, have been introduced in order to limit exposure
to dormant failure of the switches in the event of piccolo tube
failure, which could potentially compromise the structural integrity
of the wing leading edge and the effectiveness of the wing anti-ice
system.
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 February 22,
2011.

Discussion
Transport Canada Civil Aviation, which is the aviation authority
for Canada, has issued Canadian Airworthiness Directive CF-2009-49R1,
dated January 21, 2010 (referred to after this as ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:
During flight-testing of a wing anti-ice piccolo tube containing
a deliberate small breach, it was determined that the wing leading
edge thermal switches were not detecting the consequent bleed leak
at the design threshold. As a result, new Airworthiness Limitation
tasks, consisting of a functional test of the wing leading edge
thermal switches and an inspection of the wing anti-ice duct piccolo
tubes, have been introduced in order to limit exposure to dormant
failure of the switches in the event of piccolo tube failure, which
could potentially compromise the structural integrity of the wing
leading edge and the effectiveness of the wing anti-ice system. This
directive mandates the revision of the approved maintenance schedule
to include these new tasks, including phase-in schedules.
This revision clarifies the applicability of the directive for
CL-600-2A12 aircraft, serial numbers 3001 through 3066, and for CL-
600-2B16 aircraft, serial numbers 5001 through 5194. The directive
is only applicable to these aircraft if Bombardier Service Bulletin
(SB) 601-0590 [Scheduled Maintenance Instructions (MSG-3) Derived--
Qualification] has been incorporated. There is no change required to
the approved maintenance schedule if SB 601-0590 has not been
incorporated.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Bombardier has issued the following service information:
Challenger 601 Time Limits/Maintenance Checks, PSP 601-5,
Revision 38, dated June 19, 2009.
Challenger 601 Time Limits/Maintenance Checks, PSP 601A-5,
Revision 34, dated June 19, 2009.
Challenger 604 Time Limits/Maintenance Checks, CH 604
TLMC, Revision 13, dated August 12, 2009.
Challenger 605 Time Limits/Maintenance Checks, CH 605
TLMC, Revision 1, dated August 12, 2009.
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
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 103 products of U.S. registry. We also estimate that
it would take about 1 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $8,755, or $85 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
[[Page 479]]
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, 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 adding the following new AD:
Bombardier, Inc.: Docket No. FAA-2010-1307; Directorate Identifier
2010-NM-049-AD.
Comments Due Date
(a) We must receive comments by February 22, 2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the airplanes identified in paragraphs
(c)(1), (c)(2), (c)(3), and (c)(4) of this AD; certificated in any
category.
(1) Bombardier, Inc. Model CL-600-2A12 (CL-601) airplanes,
serial numbers 3001 through 3066 inclusive on which Bombardier
Service Bulletin 601-0590 has been accomplished.
(2) Bombardier, Inc. CL-600-2B16 (CL-601-3A and CL-601-3R
Variants) airplanes, serial numbers 5001 through 5194 inclusive on
which Bombardier Service Bulletin 601-0590 has been accomplished.
(3) Bombardier, Inc. CL-600-2B16 (CL-604 Variants) airplanes,
serial numbers 5301 through 5665 inclusive.
(4) Bombardier, Inc. CL-600-2B16 (CL-604 Variants) airplanes,
serial numbers 5701 and subsequent.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (j) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued operational safety of the airplane.
Subject
(d) Air Transport Association (ATA) of America Codes 30 and 36:
Ice and Rain Protection and Pneumatic, respectively.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During flight-testing of a wing anti-ice piccolo tube containing
a deliberate small breach, it was determined that the wing leading
edge thermal switches were not detecting the consequent bleed leak
at the design threshold. As a result, new Airworthiness Limitation
tasks, consisting of a functional test of the wing leading edge
thermal switches and an inspection of the wing anti-ice duct piccolo
tubes, have been introduced in order to limit exposure to dormant
failure of the switches in the event of piccolo tube failure, which
could potentially compromise the structural integrity of the wing
leading edge and the effectiveness of the wing anti-ice system.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.

paragraph (j)(1) of this AD.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service
information as follows: No differences.
Other FAA AD Provisions
(j) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft Certification Office, ANE-170, FAA, has the authority
to approve AMOCs for this AD, if requested using the procedures
found in 14 CFR 39.19. Send information to ATTN: Program Manager,
Continuing Operational Safety, FAA, New York ACO, 1600 Stewart
Avenue, Suite 410, Westbury, New York 11590; telephone 516-228-7300;
fax 516-794-5531. Before using any approved AMOC on any airplane to
which the AMOC applies, notify your principal maintenance inspector
(PMI) or principal avionics inspector (PAI), as appropriate, or
lacking a principal inspector, your local Flight Standards District
Office. The AMOC approval letter must specifically reference this
AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: A Federal agency may not conduct or
sponsor, and a person is not required to respond to, nor shall a
person be subject to a penalty for failure to comply with a
collection of information subject to the requirements of the
Paperwork Reduction Act unless that collection of information
displays a current valid OMB Control Number. The OMB Control Number
for this information collection is 2120-0056. Public reporting for
this collection of information is estimated to be approximately 5
minutes per response, including the time for reviewing instructions,
completing and reviewing the collection of information. All
responses to this collection of information are mandatory. Comments
concerning the accuracy of this burden and suggestions for reducing
the burden should be directed to the FAA at: 800 Independence Ave.,
SW., Washington, DC 20591, Attn: Information Collection Clearance
Officer, AES-200.
