DOCUMENT SUMMARY:
The FAA is superseding an existing airworthiness directive (AD) that applies to all Bombardier Model CL6002B19 (Regional Jet Series 100 & 440) airplanes and Model CL6001A11 (CL600), CL6002A12 (CL601), and CL6002B16 (CL6013A, CL6013R, and CL604) airplanes. The existing AD currently requires revising the airplane flight manuals (AFMs) to include new cold weather operations limitations and procedures. This AD requires revising the AFMs to include a requirement for flightcrew training regarding enhanced takeoff procedures and winter operations. This AD results from reports of uncommanded roll during takeoff. We are issuing this AD to prevent possible loss of control on takeoff resulting from even small amounts of frost, ice, snow, or slush on the wing leading edges or forward upper wing surfaces.
SUMMARY:
Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), et al., Airplanes, and Model CL-600-2B19 Airplanes,
SUPPLEMENTAL INFORMATION
Discussion
On April 2, 2008, the FAA issued AD 20080806, amendment 3915458
(73 FR 19989, April 14, 2008). That AD applies to all Bombardier Model
CL6002B19 (Regional Jet Series 100 & 440) airplanes and Model CL600
1A11 (CL600), CL6002A12 (CL601), and CL6002B16 (CL6013A, CL
6013R, and CL604) airplanes. That AD requires revising the airplane
flight manuals (AFMs) to include new cold weather operations limitations and
[[Page 61337]]
procedures. That AD resulted from reports of uncommanded roll during
takeoff. The actions specified in that AD are intended to prevent
possible loss of control on takeoff resulting from even small amounts
of frost, ice, snow, or slush on the wing leading edges or forward upper wing surfaces.
Actions Since AD Was Issued
The preamble to AD 20080806 specified that we considered the requirements ``interim action'' and that Transport Canada Civil Aviation (TCCA) advised that it was developing further actions, such as crew awareness and training with regard to winter operations to address the unsafe condition addressed by that AD. That AD explains that we might consider further rulemaking if those further actions are developed, approved, and available. TCCA has now advised us that the manufacturer has developed these actions, and we have determined that further rulemaking is indeed necessary; this AD follows from that determination.
Relevant Service Information
Bombardier has issued the temporary revisions (TRs) listed in the
``Temporary Revisions'' table. The temporary revisions describe
limitations that include tactile inspections for ice during certain
weather conditions, limitations and procedures for use of wing and cowl
antiice during certain taxiing or takeoff conditions, and takeoff
limitations to reduce highpitch attitudes during rotation. The
temporary revisions also describe a limitation, effective November 1,
2008, that requires flightcrew training regarding enhanced takeoff
procedures and winter operations. Accomplishing the actions specified
in the service information is intended to adequately address the unsafe
condition. TCCA mandated the service information and issued Canadian
airworthiness directives CF200815R1 and CF200816R1, both dated
August 20, 2008 (referred to after this as ``the MCAI''), to ensure the continued airworthiness of these airplanes in Canada.

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 20080806. This new AD retains certain requirements of the existing AD. This AD also requires revising the AFMs to include a requirement for flightcrew training regarding enhanced takeoff procedures and winter operations. Differences Between This AD and the Canadian Airworthiness Directives
The Canadian airworthiness directives specify that operators should advise flightcrews of the changes introduced by the TRs; and review the ``Pilot's Checklist'' to ensure that the instructions regarding selection of the wing antiice system to ``ON,'' as specified in the AFM Limitations section, are incorporated. We do not require these actions because there is no method to determine compliance with these actions.
Change to Existing AD
This AD retains certain requirements of AD 20080806; however,
certain paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this AD, as listed in the following table:
Revised Paragraph Identifiers
Corresponding requirement in
Requirement in AD 20080806 this AD

Paragraph (h)............................. Paragraph (g).
Paragraph (i)............................. Paragraph (j).
[[Page 61338]]
FAA's Justification and Determination of the Effective Date
We are rapidly approaching the ice/snow season and the pilot training regarding enhanced takeoff procedures and winter operations must be accomplished before the season begins. Because of our requirement to promote safe flight of civil aircraft and thus, the critical need to prevent uncommanded roll during takeoff 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. FAA20081096; Directorate Identifier 2008NM158AD'' 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. List of Subjects in 14 CFR Part 39

Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39AIRWORTHINESS 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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 3915458 (73 FR 19989, April 14, 2008) and adding the following new AD:
20082109 Bombardier, Inc. (Formerly Canadair): Docket No. FAA 20081096; Directorate Identifier 2008NM158AD; Amendment 39
15693.
Effective Date
(a) This AD becomes effective October 31, 2008.
Affected ADs
(b) This AD supersedes AD 20080806.
Applicability
(c) This AD applies to all Bombardier Model CL6001A11 (CL 600), CL6002A12 (CL601), CL6002B16 (CL6013A, CL6013R, & CL
604) airplanes, and Model CL6002B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category.
Note 1: Some Model CL6002B16 (CL604) airplanes might be referred to by a marketing designation as CL605.
Note 2: 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.
Unsafe Condition
(d) This AD results from reports of uncommanded roll during
takeoff. We are issuing this AD to prevent possible loss of control
on takeoff resulting from even small amounts of frost, ice, snow,
or slush on the wing leading edges or forward upper wing surfaces. Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the actions have already been done.
Restatement of AD 20080806
Revision to Airplane Flight Manual (AFM)
(f) Within 7 days after April 21, 2008 (the effective date of AD
20080806), revise the applicable sections of the applicable AFM by
inserting a copy of the applicable temporary revision (TR) listed in
Table 1 of this AD. Thereafter, operate the airplanes per the
limitation specified in the applicable TR, except as provided by
paragraphs (h) and (j) of this AD. Doing the revision required by
paragraph (h) of this AD terminates the requirements of this paragraph.
(g) When information identical to that in a TR specified in
paragraph (f) of this AD has been included in the general revisions
of the applicable AFM, the general revisions may be inserted into the AFM, and the TR may be removed from that AFM.
