RIN 2120-AA64
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet
Series 100 & 440) airplanes, that currently requires installation of
protective tape on the fire and overheat control unit located in the
flight compartment. This amendment requires the installation of
protective tape and adds repetitive inspections of the condition of the
protective tape and related corrective action. This amendment also
mandates eventual replacement of the existing fire and overheat control
unit with a modified unit, which ends the repetitive inspections.
Additionally, this amendment adds airplanes to the applicability in the
existing AD. The actions specified by this AD are intended to prevent
fluid contamination inside the fire and overheat control unit, which
could result in a false fire alarm and consequent emergency landing.
This action is intended to address the identified unsafe condition.
DATES: Effective June 12, 2006.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of June 12, 2006.
On August 22, 2003 (68 FR 42580, July 18, 2003), the Director of
the Federal Register approved the incorporation by reference of
Bombardier Alert Service Bulletin A601R-26-017, Revision ``A,'' dated
September 8, 2000.
ADDRESSES: The service information referenced in this AD may be
obtained from Bombardier, Inc., Canadair,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 2003-14-17,
amendment 39-13236 (68 FR 42580, July 18, 2003), which is applicable to
certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes, was published in the Federal Register on April 6, 2004 (69
FR 17987). This action proposed to continue to require the installation
of protective tape and to add repetitive inspections of the condition
of the protective tape and related corrective action. This action also
proposed to mandate eventual replacement of the existing fire and
overheat control unit with a modified unit, which would end the
repetitive inspections. Additionally, this action proposed to add
airplanes to the applicability in the existing AD.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
Requests To Refer to Current Revision of Service Information
Two commenters, Air Wisconsin Airlines and Bombardier, request that
we change one service information reference in the notice of proposed
rulemaking (NPRM). Bombardier states that the NPRM refers to Service
Bulletin 601R-26-018, Revision `A,' dated February 27, 2003, in several
places, although Revision `B,' dated November 6, 2003, is the current
revision. Bombardier requests that we change all references in the NPRM
from Revision `A' to Revision `B.' Air Wisconsin Airlines states that
the compliance time of ``8,000 flight hours or 36 months from the issue
date of this service bulletin,'' specified by Revision `A' has been
changed to ``20,000 flight hours from the issue date of this service
bulletin or before December 31, 2010,'' in Revision `B.' Air Wisconsin
Airlines notes that paragraph (e) of the NPRM refers to ``20,000 flight
hours'' and suggests changing the service information reference in
paragraph (e) from Revision `A' to Revision `B' to bring the ``20,000
flight hours'' into agreement with the current service information.
We have reviewed Bombardier Service Bulletin 601R-26-018, Revision
`B,' dated November 6, 2003. Except for the changed compliance time
noted and an added reference to Transport Canada Civil Aviation (TCCA),
Revision `A' and Revision `B' are essentially the same; therefore, we
agree with this request for the reasons given. We have revised
paragraphs (c), (e), and (f) of the AD to refer to Service Bulletin
601R-26-018, Revision `B,' as the appropriate source of service
information for accomplishing certain requirements of the AD.
Request To Extend Compliance Time
One commenter, Bombardier, requests that we revise the compliance
time specified in paragraph (e) of the NPRM. Bombardier states that
``20,000 flight hours or 84 months,'' is not consistent with applying
5,000 flight hours as equivalent to 24 months of operation for a
typical affected airplane. Bombardier states that ``20,000 flight hours
or 96 months,'' would more accurately reflect this application.
We partially agree. Bombardier's analysis does indicate that a
longer period of compliance time may be warranted. However, we have
determined that 89 months, rather than 96 months, would more accurately
reflect the compliance time mandated by Canadian airworthiness
directive CF-2000-35R1, dated July 2, 2003. Therefore, we have revised
paragraph (e) of the AD to specify a compliance time of ``20,000 flight
hours or 89 months after the effective date of this AD, whichever
occurs first.''
Change to Applicability
The reference to Service Bulletin 601R-26-018, Revision `A' is
changed to Revision `B' in the applicability of the AD; however, no
airplanes are added to or deleted from the applicability.
Change to Compliance Time Priority
To properly reflect the priority of the compliance times specified
in Canadian airworthiness directive CF-2000-35R1, we have revised
paragraph (d) of the AD to read, ``Within 5,000 flight hours or 24
months after the effective date of this AD, whichever occurs first.''
Credit for Use of Previous Issues of Service Information
The statement, ``This revision has no effect on aircraft which have
a previous issue of this service bulletin incorporated,'' appears in
Bombardier Service Bulletin 601R-26-018, Revision `B,' dated November
6, 2003, and in Bombardier Alert Service Bulletin A601R-26-017,
Revision `D,' dated November 6, 2003. Therefore, we have added new
paragraph (g) to the AD to give credit for actions accomplished in
accordance with Alert Service Bulletin A601R-26-017, Revision `C,'
dated November 6, 2003; and with Service Bulletin 601R-26-018, dated
December 2, 2002, and Revision `A,' dated February 27, 2003. We have
re-identified existing paragraph (g) and subsequent paragraphs in the
AD.
Clarification of Alternative Method of Compliance (AMOC) Paragraph
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Conclusion
After careful review of the available data, including the comments
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule with the changes previously
described. The FAA has determined that these changes will neither
increase the economic burden on any operator nor increase the scope of
the AD.
Cost Impact
There are about 240 airplanes of U.S. registry that will be
affected by this AD.
The installation of protective tape that is currently required by
AD 2003-14-17 takes about 1 work hour per airplane to do, at an average
labor rate of $65 per work hour. Based on these figures, the cost
impact of the currently required actions is estimated to be $65 per
airplane.
The new inspection required by this AD action will take about 1
work hour per airplane to do, at an average labor rate of $65 per work
hour. Based on these figures, the cost impact of the inspection
required by this AD on U.S. operators is estimated to be $15,600, or
$65 per airplane, per inspection cycle.
The replacement required by this AD action will take about 2 work
hours per airplane to do, at an average labor rate of $65 per work
hour. Parts cost will be minimal. Based on these figures, the cost
impact of the replacement required by this AD on U.S. operators is
[[Page 26684]]
estimated to be $31,200, or $130 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.
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 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
