Airworthiness Directives; Bombardier Model CL-600-2B19 Series
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
is applicable to certain Bombardier Model CL-600-2B19 series airplanes.
This AD requires inspection of certain installed electrical relays to
determine whether they have certain manufacturing date codes, and
replacement of the electrical relays with those date codes with new
relays with different manufacturing date codes. This action is
necessary to prevent the failure of an electrical relay due to a
defective moving blade assembly, which could result in the inability to
generate electrical power from the emergency system, if needed. This
action is intended to address the identified unsafe condition.
DATES: Effective September 18, 2002.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of September 18, 2002.
ADDRESSES: The service information referenced in this AD may be
obtained from Bombardier, Inc., Canadair, Aerospace Group, P.O. Box
6087, Station Centre-ville, Montreal, Quebec H3C 3G9, Canada. This
information may be examined at the Federal Aviation Administration

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain Bombardier Model CL-600-
2B19 series airplanes was published in the Federal Register on April 4,
2002 (67 FR 16067). That action proposed to require inspection of
certain installed electrical relays to determine whether they have
certain manufacturing date codes, and replacement of the electrical
relays with those date codes with new relays with different
manufacturing date codes.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Explanation of Credit Language
Since the language in Notes 2, 3, and 4 of the proposed AD is
regulatory in nature, the notes have been redesignated as paragraphs
(b), (e), and (g) in this final rule. The remaining paragraphs of this
final rule have been redesignated to accommodate these changes.
Conclusion
After careful review of the available data, the FAA has determined
that air safety and the public interest require the adoption of the
rule with the changes described previously. The FAA had determined that
these changes will neither increase the economic burden on any operator
nor increase the scope of the AD.
Cost Impact
The FAA estimates that 160 airplanes of U.S. registry will be
affected by this AD. It will take approximately 1 work hour per
airplane to accomplish the required inspection at an average labor rate
of $60 per work hour. Based on these figures, the cost impact of the
required inspection on U.S. operators is estimated to be $9,600, or $60
per airplane.
It will take approximately 2 work hours per airplane to accomplish
the required replacement of suspect relay K1XC at an average labor rate
of $60 per work hour. There will be no charge for the replacement part.
Based on these figures, the cost impact of the required replacement of
suspect relay K1XC on U.S. operators is estimated to be a maximum of
$19,200, or $120 per airplane.
It will take approximately 2 work hours per airplane to accomplish
the required replacement of suspect relays K2XD and K3XD at an average
labor rate of $60 per work hour. There will be no charge for the
replacement parts. Based on these figures, the cost impact of the
required replacement of suspect relays K2XD or K3XD on U.S. operators
is estimated to be a maximum of $19,200, or $120 per airplane.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the requirements of this
AD action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
Regulatory Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
