(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 all Bombardier Model CL-600-2B19 (Regional Jet 
Series 100 & 440) airplanes and Model CL-600-1A11 (CL-600), CL-600-2A12 
(CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) series 
airplanes. The existing AD currently requires revising the airplane 
flight manuals (AFMs) to include a new cold weather operations 
limitation. This AD requires revising the AFMs to modify the cold 
weather operations limitation and include additional limitations and 
procedures. This AD results from reports of uncommanded roll during 
take-off. We are issuing this AD to prevent possible loss of control on 
take-off resulting from even small amounts of frost, ice, snow, or 
slush on the wing leading edges or forward upper wing surfaces.

DATES: This AD becomes effective April 21, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of April 21, 
2008.
    On February 22, 2005 (70 FR 8025, February 17, 2005), the Director 
of the Federal Register approved the incorporation by reference of 
certain other publications.
    We must receive any comments on this AD by May 14, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

    On February 10, 2005, the FAA issued AD 2005-04-07, amendment 39-
13979 (70 FR 8025, February 17, 2005). That AD applies to all 
Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes 
and Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 
(CL-601-3A, CL-601-3R, and CL-604) series airplanes. That AD requires 
revising the airplane flight manuals to include a new cold weather 
operations limitation. That AD resulted from a report that even small 
amounts of frost, ice, snow, or slush on the wing leading edges or 
forward upper wing surfaces can cause an adverse change in the stall 
speeds, stall characteristics, and the protection provided by the stall 
protection system. The actions specified in that AD are intended to 
prevent possible loss of control on take-off 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

    Since we issued that AD, Transport Canada Civil Aviation (TCCA) 
informed us that there were three incidents in which Model CL-600-2B19 
and CL-600-2B16 airplanes experienced uncommanded roll during take-off. 
TCCA advises that it is necessary to further revise the AFM limitations 
and procedures for cold weather or icing conditions.

Relevant Service Information

    Bombardier has issued the temporary revisions (TRs) listed in the 
following table. The temporary revisions describe limitations that 
include tactile inspections for ice during certain weather conditions. 
The temporary revisions also describe limitations and procedures for 
use of wing and cowl anti-ice during certain taxiing or take-off 
conditions, and revised take-off limitations to reduce high-pitch 
attitudes during rotation. TCCA mandated the service information and 
issued Canadian emergency airworthiness directives CF-2008-15, dated 
March 7, 2008, and CF-2008-16, dated March 10, 2008, to ensure the 
continued airworthiness of these airplanes in Canada.

FAA's Determination and Requirements of This AD

    These airplanes are manufactured in Canada and are 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 products of this type design that are certificated for 
operation in the United States.
    Therefore, we are issuing this AD to supersede AD 2005-04-07. This 
new AD retains the requirements of the existing AD. This AD also 
requires revising the AFMs to include revised and additional 
limitations and procedures specified in the temporary revisions 
described previously.

Clarification of AD Compliance Time

    Due to the degree of urgency associated with the subject unsafe 
condition, this AD specifies a compliance time of within 7 days after 
the effective date of this AD to more closely coincide with the time 
the Canadian airworthiness directives must be accomplished. Canadian 
airworthiness directive CF-2008-15 specifies a compliance time of 
within 21 days after March 10, 2008 (the effective date of Canadian 
airworthiness directive CF-2008-15). Canadian airworthiness directive 
CF-2008-16 specifies a compliance time of within 21 days after March 
12, 2008 (the effective date of Canadian airworthiness directive CF-
2008-16).

Differences Between This AD and the Canadian Airworthiness Directives

    The Canadian airworthiness directives specify that operators should 
advise flight crews of the changes introduced by the TRs; and review 
the ``Pilot's Checklist'' to ensure that the instructions regarding 
selection of the wing anti-ice 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.
    The Canadian airworthiness directives specify that operators should 
insert a copy of the Canadian airworthiness directive in the AFM, but 
this AD does not require the insertion. We have determined that this 
action is unnecessary since all relevant wording is within the required 
temporary revisions, which are required to be inserted in the AFM.
    The Canadian airworthiness directives specify certain temporary 
revision documents. After the Canadian airworthiness directives were 
issued, Bombardier issued new TRs that include instructions on the cowl 
anti-ice. TCCA does not plan to revise its airworthiness directives to 
incorporate the new TRs. However, it is our practice to refer to the 
most recent and appropriate service information available in our ADs.
    These differences have been coordinated with TCCA.

Interim Action

    This is considered to be interim action. TCCA has advised that it 
currently is developing further actions, such as crew awareness and 
training with regard to winter operations, that will address the unsafe 
condition addressed by this AD. Once this information is developed, 
approved, and available, the FAA might consider additional rulemaking.

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 assure safe operation during cold 
weather (ice/snow conditions) 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.

[[Page 19991]]

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-2008-0408; Directorate 
Identifier 2008-NM-068-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.
