Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2004-19496; Directorate Identifier 2003-NM-181-AD;
Amendment 39-13920; AD 2004-26-08]
RIN 2120-AA64
Airworthiness Directives; Bombardier Model CL-215-6B11 (CL215T
Variant) and CL-215-6B11 (CL415 Variant) Series Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier Model CL-215-6B11 (CL215T variant) and CL-215-6B11
(CL415 variant) series airplanes. This AD requires replacing the
mounting pad studs of the auxiliary feather pump with new, longer
studs, and installing a pressure relief valve. This AD is prompted by a
few incidents of external oil leaks from the oil pump of the power
control unit due to a malfunction of the pressure regulating valve. We
are issuing this AD to prevent fracturing of the pump body, which could
result in loss of engine oil, and consequent inability to maintain
engine oil pressure and to feather the propeller.
DATES: This AD becomes effective February 9, 2005.
The incorporation by reference of certain publications listed in
the AD is approved by the Director of the Federal Register as of
February 9, 2005.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with an AD for certain Bombardier Model CL-215-6B11 (CL215T variant)
and CL-215-6B11 (CL415 variant) series airplanes. That action,
published in the Federal Register on November 3, 2004 (69 FR 63968),
proposed to require replacing the mounting pad studs of the auxiliary
feather pump with new, longer studs, and installing a pressure relief
valve.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been submitted on the proposed
AD or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
The following table provides the estimated costs for U.S. operators
to comply with 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
[[Page 685]]
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.
