ACTION: Final rule; request for comments. cprice-sewell on PROD1PC62 with RULES AGENCY: 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, VerDate Aug<31>2005 15:37 Apr 11, 2008 Jkt 214001 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.

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.

Canadair Temporary Revision RJ/155– 3. 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. cprice-sewell on PROD1PC62 with RULES 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 VerDate Aug<31>2005 15:37 Apr 11, 2008 Jkt 214001 March 20, 2008 ...... March 20, 2008 ...... March 20, 2008 ...... March 20, 2008 ...... March 20, 2008 ...... March 20, 2008 ...... March 20, 2008 ...... March 20, 2008 ...... March 20, 2008 ...... March 25, 2008 ...... 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 antiice. 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 PO 00000 Frm 00032 Fmt 4700 Sfmt 4700 Canadair Regional Jet AFM, CSP A– 012. 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. E:\FR\FM\14APR1.SGM 14APR1 Federal Register / Vol. 73, No. 72 / Monday, April 14, 2008 / Rules and Regulations 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 https:// 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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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: I PART 39—AIRWORTHINESS DIRECTIVES 1.

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.

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 https://
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.
