14 CFR Part 39
[Docket No. FAA-2005-22873; Directorate Identifier 2005-NM-197-AD]
RIN 2120-AA64
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 &
440) airplanes. This proposed AD would require replacing the Camloc
fasteners on the sidewall of the center pedestal. This proposed AD
results from reports of the Camloc fasteners on the sidewall of the
center pedestal disengaging and interfering with an inboard rudder
pedal. We are proposing this AD to prevent these fasteners from
disengaging and interfering with an inboard rudder pedal, which could
reduce directional controllability of the airplane.
DATES: We must receive comments on this proposed AD by December 15,
2005.
ADDRESSES: Use one of the following addresses to submit comments on
this proposed AD.

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 several reports of the
Camloc fasteners on the sidewall of the center pedestal fully
disengaging and interfering with an inboard rudder pedal. In one
incident, the rudder jammed during an approach due to a disengaged
Camloc fastener that restricted movement of the pilot's inboard rudder
pedal and tow brake. This condition, if not corrected, could reduce
directional controllability of the airplane.
Relevant Service Information
Bombardier has issued Service Bulletin 601R-31-030, Revision F,
dated September 1, 2005. The service bulletin describes procedures for
replacing, with screws and nut plate assemblies, the Camloc fasteners
on the left and right sidewalls of the center pedestal. 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 directive CF-2004-23R1,
dated July 18, 2005, to ensure the continued airworthiness of these
airplanes in Canada.
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 proposing this AD, which would require
accomplishing the actions specified in the service information
described previously.
Costs of Compliance
This proposed AD would affect about 718 airplanes of U.S. registry.
The proposed actions would take about 1 work hour per airplane, at an
average labor rate of $65 per work hour. Required parts would cost
about $135 per airplane. Based on these figures, the estimated cost of
the proposed AD for U.S. operators is $143,600, or $200 per airplane.
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 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 distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that the 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. See the
ADDRESSES section for a location to examine the regulatory evaluation.

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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2005-22873;
Directorate Identifier 2005-NM-197-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by December
15, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) airplanes, certificated in any category,
serial numbers 7003 through 7986 inclusive.
Unsafe Condition
(d) This AD results from reports of the Camloc fasteners on the
sidewall of the center pedestal disengaging and interfering with an
inboard rudder pedal. We are issuing this AD to prevent these
fasteners from disengaging and interfering with an inboard rudder
pedal, which could reduce directional controllability of the
airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within
[[Page 69293]]
the compliance times specified, unless the actions have already been
done.
Replacement of Fasteners
(f) Within 5,500 flight hours after the effective date of this
AD, replace, with screws and nut plate assemblies, the Camloc
fasteners on the left and right sidewalls of the center pedestal, in
accordance with the Accomplishment Instructions of Bombardier
Service Bulletin 601R-31-030, Revision F, dated September 1, 2005.
Actions Accomplished Previously
(g) Replacing fasteners before the effective date of this AD in
accordance with the Accomplishment Instructions of one of the issues
of Bombardier Service Bulletin 601R-31-030 identified in Table 1 of
this AD is acceptable for compliance with the requirements of
paragraph (f) of this AD.
