14 CFR Part 39
[Docket No. FAA-2004-19763; Directorate Identifier 2004-NM-187-AD;
Amendment 39-13969; AD 2005-03-13]
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: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes. This AD requires doing repetitive inspections for fractures
and cracks of the links of the aileron power control unit (PCU);
replacing any fractured/cracked link; and doing applicable related
investigative and corrective actions, if necessary. This AD is prompted
by reports indicating that the links of the aileron PCU have failed. We
are issuing this AD to prevent failure of both links of the aileron
PCU, which could result in reduced lateral control of the airplane.
DATES: This AD becomes effective March 23, 2005.
The incorporation by reference of a certain publication listed in
the AD is approved by the Director of the Federal Register as of March
23, 2005.
ADDRESSES: For service information identified in this AD, contact
Bombardier, Inc., Canadair, Aerospace Group, P.O. Box 6087, Station
Centre-ville, Montreal, Quebec H3C 3G9, Canada. You can examine this

final disposition. You can examine the AD docket on the Internet at

identifier for this docket is 2004-NM-187-AD.
FOR FURTHER INFORMATION CONTACT: Dan Parrillo, Aerospace Engineer,
Systems and Flight Test Branch, ANE-172, FAA, New York Aircraft
Certification Office, 1600 Stewart Avenue, Westbury, suite 410, New
York 11590; telephone (516) 228-7305; fax (516) 794-5531.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with an AD for certain Bombardier Model CL-600-2B19 (Regional Jet
Series 100 & 440) airplanes. That action, published in the Federal
Register on December 7, 2004 (69 FR 70571), proposed to require doing
repetitive inspections for fractures and cracks of the links of the
aileron power control unit (PCU); replacing any fractured/cracked link;
and doing applicable related investigative and corrective actions, if
necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the one comment that was
submitted on the proposed AD. The commenter supports the proposed AD.
Conclusion
We have carefully reviewed the available data, including the
comment that has been submitted, and determined that air safety and the
public interest require adopting the AD as proposed.
Interim Action
This is considered to be interim action until final action is
identified, at which time we may consider further rulemaking.
Costs of Compliance
This AD will affect about 697 airplanes of U.S. registry. The
required inspection will take about 1 work hour per airplane, at an
average labor rate of $65 per work hour. Based on these figures, the
estimated cost of the AD for U.S. operators is $45,305, or $65 per
airplane, per inspection cycle.
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,
[[Page 7846]]
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. See the ADDRESSES section for a location to
examine the regulatory evaluation.

Repetitive Inspections
(f) Before the accumulation of 2,000 total flight hours, or

the Accomplishment Instructions of Bombardier Alert Service Bulletin
A601R-27-130, Revision ``B,'' including Appendices A and B, dated
May 11, 2004. Repeat the detailed inspection thereafter at intervals
not to exceed 1,000 flight hours.
Note 1: For the purposes of this AD, a detailed inspection is
``an intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirrors magnifying lenses, etc. may be necessary. Surface cleaning
and elaborate procedures may be required.''
Corrective Action
(g) If any fractured or cracked link is detected during any
inspection required by paragraph (f) of this AD, before further
flight, replace the fractured/cracked link and do the applicable
related investigative and corrective actions by doing all the
actions in accordance with Part B of the Accomplishment Instructions
of Bombardier Alert Service Bulletin A601R-27-130, Revision ``B,''
including Appendices A and B, dated May 11, 2004; except as required
by paragraph (h) of this AD.
(h) If any crack is found on the aileron lugs during any related
investigative action required by paragraph (g) of this AD, and the
service bulletin recommends contacting Bombardier for disposition:
Before further flight, disposition and replace the cracked aileron
lug in accordance with a method approved by the Manager, New York
Aircraft Certification Office (ACO), FAA, or Transport Canada Civil
Aviation (TCCA) (or its delegated agent).
Acceptable Revisions of the Referenced Service Bulletin
(i) Actions specified in paragraphs (f) and (g) of this AD done

(k) of this AD.
(k) Airplanes on which a fractured or cracked link of the
aileron PCU was found that were not subject to an NDT inspection of
the aileron lugs (i.e., related investigative action required by
paragraph (h) of this AD) before the effective date of this AD must
do an NDT inspection of the applicable lugs in accordance with
paragraph (g) of this AD at the next repetitive detailed inspection
of the link of the aileron PCU required by this AD.
