14 CFR Part 39
[Docket No. FAA-2005-22793; Directorate Identifier 2005-NM-161-AD;
Amendment 39-14462; AD 2006-02-10]
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 replacing the Gask-O-Seal in the coupling
of the refuel/defuel shut-off valves. This AD results from a report
that Gask-O-Seals that did not incorporate an integral restrictor to
limit fuel flow rate and fuel pressure during refueling were installed
on certain airplanes. We are issuing this AD to prevent a buildup of
excessive static charge, which could create an ignition source inside
the fuel tank.
DATES: This AD becomes effective March 1, 2006.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of March 1,
2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Management Facility, U.S.
Department of Transportation, 400 Seventh Street SW., Nassif Building,
room PL-401, Washington, DC.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at http://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Bombardier
Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. That NPRM
was published in the Federal Register on October 27, 2005 (70 FR
61920). That NPRM proposed to require replacing the Gask-O-Seal in the
coupling of the refuel/defuel shut-off valves.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the single comment received.
Request To Reference Latest Issue of Service Bulletin
One commenter requests that the NPRM reference Bombardier Alert
Service Bulletin A601R-28-064, Revision `A,' dated September 15, 2005
(Bombardier Alert Service Bulletin A601R-28-064, dated April 21, 2005,
was referenced as the appropriate source of service information for
doing the actions in the NPRM). The commenter notes that Revision `A'
of the alert service bulletin is the latest issue with updated
information.
We agree with the commenter. The actions in Revision `A' of the
alert service bulletin are essentially the same as the actions in the
original issue. We have revised this AD to reference Revision `A' of
the alert service bulletin. We have also added paragraph (g) to this AD
to give credit for actions done in accordance with the original issue
of the alert service bulletin and reidentified subsequent paragraphs
accordingly.
Conclusion
We have carefully reviewed the available data, including the
comment received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
The following table provides the estimated costs for U.S. operators
to comply with this AD.

Action Work hours labor rate Parts Cost per registered Fleet cost

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
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 and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
