14 CFR Part 39
[Docket No. 2001-NM-250-AD; Amendment 39-13013; AD 2003-01-02]
RIN 2120-AA64
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series
100 & 440) series airplanes, that requires replacement of the existing
smoke detectors in the cargo compartment with new, improved smoke
detectors. This amendment is prompted by mandatory continuing
airworthiness information from a civil airworthiness authority. The
actions specified by this AD are intended to prevent false smoke
warnings from the smoke detectors in the cargo compartment. A false
smoke warning prompts the flightcrew to discharge fire extinguisher
bottles, leaving those bottles depleted in the event of an actual fire.
Repeated false smoke warnings create uncertainty as to whether an
emergency landing and emergency evacuation of passengers and flightcrew
is warranted.
DATES: Effective February 18, 2003.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of February 18, 2003.
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
(FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue,
SW., Renton, Washington; or at the FAA, New York Aircraft Certification
Office, 10 Fifth Street, Third Floor, Valley Stream, New York; or at
the Office of the Federal Register, 800 North Capitol Street, NW.,
suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: Dan Parrillo, Aerospace Engineer, ANE-
172, FAA, New York Aircraft Certification Office, 10 Fifth Street,
Third Floor, Valley Stream, New York; telephone (516) 256-7505; fax
(516) 568-2716.
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 as a second supplemental notice of
proposed rulemaking (NPRM) in the Federal Register on August 16, 2002
(67 FR 53525). That action proposed to require replacement of the
existing smoke detectors in the cargo compartment with new, improved
smoke detectors. That action also proposed to include spare part
information.

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 Change to Applicability
We have revised the applicability of the final rule to identify
model designations as published in the most recent type certificate
data sheet for the affected models.
Explanation of Editorial Change
We have changed the service bulletin citations throughout this
final rule to exclude the CRJ 100/200 Service Bulletin Compliance
Facsimile Reply Sheet and Service Bulletin Comment Sheet--Facsimile
Reply Sheet. (Those forms are intended to be completed by operators and
submitted to the manufacturer to provide input on the quality of the
service bulletins and report compliance; however, this AD does not
include such requirements.)
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 change previously described. The FAA has determined that
this change will neither increase the economic burden on any operator
nor increase the scope of the AD.
Cost Impact
The FAA estimates that 281 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 2 work hours per
airplane to accomplish the required replacement of the existing smoke
detectors in the cargo compartment with new, improved smoke detectors,
and that the average labor rate is $60 per work hour. The cost of
required parts is approximately $4,136 ($876 for one smoke detector kit
and $1,630 each for two smoke detectors). Based on these figures, the
cost impact of the AD on U.S. operators is estimated to be $1,195,936,
or $4,256 per airplane.
The cost impact figure discussed above is 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

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:

Docket 2001-NM-250-AD.
Applicability: Model CL-600-2B19 (Regional Jet Series 100 & 440)
series airplanes, serial numbers 7003 through 7480 inclusive;
certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must request approval for an
alternative method of compliance in accordance with paragraph (c) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent false smoke warnings from the smoke detectors in the
cargo compartment, which prompt the flightcrew to discharge fire
extinguisher bottles, leaving those bottles depleted in the event of
an actual fire, or which create uncertainty as to whether an
emergency landing and emergency evacuation of passengers and
flightcrew is warranted, accomplish the following:
Replacement
(a) Within 18 months after the effective date of this AD:
Replace the existing smoke detectors having part number (P/N)
473052, which are located in the cargo compartment, with new,

appropriate FAA Principal Maintenance Inspector, who may add
comments and then send it to the Manager, New York ACO.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the New York ACO.

(d) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
