Airworthiness Directives; Bombardier Model CL-600-2C10 (Regional
Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and
CL-600-2D24 (Regional Jet Series 900) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier Model CL-600-2C10 (Regional Jet Series 700, 701, &
702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional
Jet Series 900) airplanes. This AD requires replacing the Camloc
fasteners on the sidewall of the center pedestal. 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.
DATES: This AD becomes effective March 24, 2006.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of March 24,
2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Management Facility, U.S.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at http://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Bombardier
Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15
(Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900)
airplanes. That NPRM was published in the Federal Register on November
9, 2005 (70 FR 67946). That NPRM proposed to require replacing the
Camloc fasteners on the sidewall of the center pedestal.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the single comment received.
[[Page 8442]]
Request To Allow Use of Alternative Parts
The commenter agrees with the proposed 5,500-flight-hour compliance
time. But the commenter requests that we allow installation of
operator-supplied hardware with operator-fabricated gang-nut plates in
lieu of the parts specified in the referenced service bulletin. The
commenter states that this will facilitate compliance with the proposed
AD because operators will not be dependent on parts availability.
We do not agree with the commenter's request. We have discussed the
question of parts availability with the manufacturer, and the
manufacturer states that there is no problem with availability of the
kit needed to complete the requirements of this AD. Therefore, parts
availability does not justify allowing operators to install parts other
than those specified in the service bulletin. Also, it is not
appropriate to address such a request in an AD. We recommend that the
commenter apply for approval of an alternative method of compliance
(AMOC) and provide specific information about the hardware proposed in
the comment. Operators who choose to submit an AMOC request should
include data supporting that the proposed alternative hardware will
provide an acceptable level of safety. We have not changed the final
rule in this regard.
Conclusion
We have carefully reviewed the available data, including the
comment received, and determined that air safety and the public
interest require adopting the AD as proposed.
Costs of Compliance
This AD affects about 209 airplanes of U.S. registry. The required
actions will take about 2 work hours per airplane, at an average labor
rate of $65 per work hour. Required parts will cost between $141 and
$150 per airplane. Based on these figures, the estimated cost of this
AD for U.S. operators is between $56,639 and $58,520, or between $271
and $280 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 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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under 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.
